Publication date: 2007-8-31 16:48:36. 1. Purpose: Office buildings, substations, and production facilities where electricity is used, as well as employee dormitories, are crowded with people and contain numerous electrical installations; high electricity consumption makes these places prone to electrical fires. In the event of a fire, it can easily lead to casualties, property losses, and serious environmental pollution incidents. To ensure the safety of people, this emergency response plan has been formulated. 2 Responsibilities and Division of Labor of the Command Structure 　2.1 Command Structure: This bureau has established a “Command Leadership Group” for emergency rescue in cases of electrical fire accidents: Team leader: Director; Deputy team leaders: Person in charge of safety, Person in charge of marketing; Members: Head of the wiring team, Head of the metering team, Material manager, Cashier. 2.2 Responsibilities of the Command Structure 2.2.1 Command Leadership Group: Responsible for formulating and revising emergency response plans, establishing specialized emergency rescue teams, and organizing the implementation of such plans as well as conducting drills ； Inspection and supervision as preventive measures against major accidents and various preparations for emergency response ； 2.2.2 Leadership team: Issues and revokes emergency rescue orders and signals in the event of an accident ； Organize and direct the rescue team to carry out rescue operations ； Report the accident to superiors and relevant authorities, and submit a request for assistance to the hospital and the county fire department if necessary ； Organize accident investigations and summarize the experiences and lessons learned from emergency rescue efforts. 2.2.3 Division of responsibilities among team leaders 2.2.3.1 Team leader: Responsible for acting as the overall commander at the scene in case of a fire, organizing personnel to handle the fire incident and preventing it from spreading further ； Responsible for organizing investigations into fire incidents and reporting to the higher-level authorities, as well as approving the corrective and preventive measures taken ； 2.2.3.2 Deputy team leader: Assists the team leader in handling the specific tasks related to emergency rescue ； 2.2.3.3 Responsibilities of the line team leader: Responsible for organizing the evacuation of personnel and the relocation of on-site staff ； Investigate the causes of fire accidents and report to the top management ； 2.2.3.4 Responsibilities of the safety specialist: Assist the line team in organizing on-site management, instruct staff on basic safety knowledge to prevent accidents from escalating, participate in investigations into the causes of fires, and develop corrective and preventive measures ； 2.2.3.5 The dedicated marketing staff is responsible for directing the resumption of production following an electrical fire accident, as well as for managing supplies and organizing the urgent provision of production equipment or dealing with related incidents ； 2.2.3.6 The dedicated marketing staff is responsible for participating in the claims processing following electrical fire incidents ； 2.2.3.8 The metering team is responsible for (organizing) first aid personnel: it is tasked with taking emergency measures for those who suffer accidents at the scene, as well as preparing medical protective equipment for first aid purposes ； 2.2.3.9 Part-time fire safety officers in each team: Responsible for the daily fire safety tasks within their respective units; 2.2.3.10 On-site staff: Must report a fire immediately and take emergency measures to extinguish it before the firefighters arrive, while also obeying instructions regarding evacuation ； Report the witnessed details of the fire truthfully. 3 Emergency Plan: In the event of a fire in the office building where work is carried out, the offices of various production teams, substations, employee dormitories, power distribution rooms, and the cable compartments within substations, the person in charge on site should remain calm. The staff present or other individuals should also stay clear-headed, call the emergency services immediately, and take the following rescue measures promptly: 3.1 Call the emergency services right away (emergency number: 119) and activate the alarm system without delay. The person who reports the fire should provide the fire department with accurate information regarding the time and location of the fire, the nature of the materials burning, the extent of the fire, as well as their own name and contact number. Someone should also be stationed at an intersection to guide the fire trucks to the accident site quickly so that they can extinguish the fire. It is also necessary to report to the top management, the Economic Security Department (2270), department heads, and the head of the Safety Inspection Department, and to promptly inform the relevant safety officers and emergency responders; these individuals must arrive at the scene as soon as possible. In the event of injuries or deaths, the affected party should contact the health center (0733-8142793) or the nearest hospital at the accident site, as well as call 120 to request assistance. 　3.2 In the event of a fire involving electrical equipment, it is necessary to first cut off the power supply to that equipment, call 119 for help, and inform the unit’s management, the Safety Inspection Department, and the Economic Security Department. Those present at the scene should promptly take action to extinguish the fire ； The Economic Defense Department is responsible for organizing the evacuation of people, ensuring that no casualties, overcrowding, or expansion of accidents occur during the evacuation process, and urging people to evacuate through safe routes. Notify the property management company (2210) promptly to shut down the elevator to prevent people from evacuating via it. 　3.3 In the event of a fire involving live electrical equipment, personnel at the scene who are familiar with such equipment should take charge or lead the efforts to extinguish the fire. To extinguish fires, dry chemical fire extinguishers, carbon dioxide fire extinguishers, or 1211 fire extinguishers should be used; tap water or foam fire extinguishers must not be employed. 　3.4 In the event of a fire in equipment such as transformers and oil switches that require filling with oil, foam extinguishers or dry sand should be used to put out the fire. 　3.5 When extinguishing fires at live electrical equipment, firefighters must not use water directly if they are not wearing insulating shoes and gloves, as this could lead to electric shock accidents. 　3.6 Generally, within 10 minutes of a fire breaking out, it is the critical period when it is easiest to extinguish the fire. After this time, as the fire spreads, ordinary firefighting methods become ineffective. Therefore, at the onset of a fire, all people present should call for help, try to put out the fire, and rescue others, using whatever means are available—including fire extinguishers, water, sand, etc.—to quickly suppress the initial flames, and they should also strive to leave the dangerous area as soon as possible. 　3.7 After a fire breaks out, those at the scene of the accident should not panic. They should find a wet towel nearby to cover their mouth and nose, or lie face down on the ground in order to get out of the smoke-filled area as quickly as possible, thereby avoiding harm from toxic gases. When fighting fires, firefighters should take extra precautions to protect themselves, wearing appropriate protective equipment as much as possible. If conditions permit at the scene, it is especially important to wear gas masks to prevent further poisoning incidents. For those who have been rescued from poisoning, they should be moved to a place with fresh air as soon as possible, and then taken to the hospital promptly for treatment. 　3.8 In the presence of an open flame, wet your hair and clothes to prevent them from catching fire; if your clothes do catch fire, extinguish it immediately on the spot. 　3.9 Proper use of common fire extinguishers ； 　　 3.9.1 Usage of dry powder fire extinguishers: To use it, hold the nozzle in one hand and point it at the source of fire; then lift the pull ring with the other hand, and a thick cloud of powder mist will be released to cover the burning area and extinguish the fire. 　　 3.9.2 How to use a foam fire extinguisher: When using it, hold the handle with one hand and support the bottom with the other; then turn the extinguisher upside down and shake it a few times, and the foam will be discharged. Be careful not to use a foam fire extinguisher on people, do not open the cylinder lid, and do not use it together with water. 　　 3.9.3 Usage method of the 1211 fire extinguisher: First, remove the safety pin when using it. Hold the handle with one hand and aim the nozzle at the base of the fire with the other hand; pressing the handle will activate it, allowing you to sweep back and forth while moving forward rapidly. 　3.10 Preventive Measures 　　 3.10.1 Safety managers at all levels should regularly inspect fire protection facilities such as fire alarm systems, fire hydrants, fire buckets, and fire extinguishers to ensure their effectiveness. 　　 3.10.2 Safety managers at all levels regularly conduct safety inspections on site to eliminate potential hazards. 　　 3.10.3 The dedicated safety officer is responsible for organizing fire safety education and training to ensure that personnel at all levels are familiar with fire safety knowledge, thereby enhancing their awareness of fire safety and preventing incidents before they occur.

Basic methods for handling substation accidents: Power equipment and power systems often experience various abnormal conditions or accidents during operation. Handling matters correctly and in a timely manner is an important basic responsibility and skill for the operators on duty at substations. ? 1 General principles? In the event of an accident, the personnel on duty must promptly and accurately determine the situation and make quick records, report to the superior dispatchers and relevant responsible persons, swiftly and correctly execute the dispatch orders and instructions from the operation supervisors, and handle the matter in accordance with the relevant regulations. ? ① Rapidly contain the spread of the accident, eliminate its root causes, and remove threats to personnel and equipment ； ? ② Use every possible method to keep the equipment running in order to maintain normal power supply to users and the lines ； ? ③ Restore power to the users and lines that have lost power as soon as possible. ? In the event of an accident, only leaders and staff involved in accident handling are allowed to remain in the control room; all other personnel should leave voluntarily, and unrelated work teams should suspend their work and leave the site. The remaining personnel in the control room should keep as quiet as possible to avoid interfering with the crew’s efforts to handle the incident. ? Keep a clear head when dealing with accidents, and proceed under the unified leadership of the on-duty shift supervisor. During the handling of an accident, it is necessary to maintain close contact with the higher-level dispatchers and follow their orders at all times. Once the incident is resolved, it should be reported promptly to the relevant supervisors. After the incident is resolved, a detailed record of the incident and the handling process should be kept, along with all phone recordings for future reference. ? The technical personnel in the substation should regularly organize accident records and discuss together whether the procedures taken to handle accidents were correct. By combining this with training activities such as accident scenario planning and counter-accident drills, safety education can be provided to employees, thereby improving the ability of those on duty to handle accidents. ? 2 Accident Handling? (1) Line accident handling:? ① In the event of a line trip, operators should immediately determine the details and report to the higher-level dispatching authorities and team leaders, including whether the circuit breaker has reset, whether there is voltage on the line, and which relay protection and automatic devices have been activated ； ? ② Thoroughly inspect the primary equipment associated with the circuits in this facility for any obvious signs of faults ； ? ③ If there is still voltage in the line after the three-phase circuit breakers trip, care should be taken to prevent an increase in voltage at the far end due to the long length of the line; if necessary, request the dispatch to disconnect the circuit breaker on the opposite side. ? ④ Power restoration attempts after failed tripping and reclosing at both ends shall be carried out in accordance with the dispatcher’s instructions. Reclosing should be disabled during trial delivery. ? (2) Handling of transformer accidents: ? ① If the tripping of a transformer causes other transformers to become overloaded, a spare transformer should be brought online as soon as possible, or the load should be reduced within the specified time frame ； ? ② Determine the cause of the fault based on the operation of the relay protection devices and external observations; power supply must not be restored until the cause is identified and the fault is resolved ； ? ③ When abnormal operating conditions of the transformer are detected, such as internal cracking sounds, abnormally high and rising temperatures, oil leakage from the oil conservator or explosion vent, a significant drop in oil level, severely abnormal results from oil analysis, severe damage to the bushings, and discharge phenomena, an outage should be requested for corrective action. ? (3) Handling of electrical misoperation accidents: ? ① In the event of a misoperation, it is necessary to remain calm, rescue personnel as quickly as possible, and restore normal operation of the equipment ； ? ② If a circuit breaker is closed incorrectly, it should be disconnected immediately; for a circuit breaker that has been closed incorrectly, it should be reopened based on the actual situation or in accordance with the dispatcher’s instructions ； ? ③ If the isolating switch is closed under load, it is strictly prohibited to open it again; first, the circuit breaker directly connected to this isolating switch must be turned off ； If a disconnect switch is pulled while under load, it must not be closed again until the connected circuit breaker is turned off. ? ④ If the grounding switch is closed by mistake, it should be reopened immediately. ? (4) Handling of faults in the AC and DC power supplies: ? ① If a fault occurs that results in the interruption of both AC and DC power supplies, it is necessary to activate the backup power supply as soon as possible. Attention should be paid to restoring critical loads first, in order to avoid excessive current surges ； If it is at night, necessary accident lighting must be provided ； ? ② During the processing, attention should be paid to the impact of AC and DC power supplies on the operating condition of the equipment; the equipment must be thoroughly inspected to restore any conditions that cannot be restored automatically. ? ③ The identification of the DC ground point must be carried out strictly in accordance with on-site procedures; it is not allowed to cause another point of grounding or a DC short circuit ； ? ④ Quickly identify the cause of the fault and eliminate it as soon as possible. ? 3 Conclusion? It is very important for duty personnel to be familiar with the methods for handling electrical equipment accidents, as this requires not only the accumulation of experience but also continuous learning of relevant regulations and an understanding of the technical specifications of electrical equipment. The duty personnel should regularly carry out various activities such as accident scenario planning and discussions on safety measures, in order to enhance their understanding of how to handle accidents. This ensures that they can remain calm and organized when an accident actually occurs, thereby improving the efficiency of accident response.

II. Basis: With the economic development of ** City, the demand for electricity is increasing rapidly. The power grid in the ** area is continuously expanding. To address various accidents that may occur under the new operating conditions of the grid, an emergency response plan for the power grid in the ** area has been formulated in accordance with relevant laws and regulations, industry standards and procedures, as well as emergency response plans. III. Principles: 1. Basic principles: ① Prevention first. Adhering to the principles of \"safety first, prevention foremost, and constant readiness,\" we strengthen power safety management, focus on the prevention and control of emergencies, conduct regular safety inspections, identify and address equipment defects in a timely manner, and effectively prevent serious and major accidents in power production ； Targeted anti-accident drills are carried out to enhance the capacity of the power grid in **region to handle severe emergencies, conduct emergency rescue operations, and restore normal power supply operations promptly. ② Unified command. In the face of grid emergencies, the principle of \"unified command, organized implementation, and effective measures\" is followed. Under the unified command and coordination of leaders at all levels, relevant agencies, and the provincial power control center, active and effective emergency response efforts are carried out, including dealing with emergencies, carrying out rescue operations in case of accidents, restoring the grid, providing emergency assistance, maintaining stability, and resuming power generation. ③ Hierarchical partitioning. Establish an emergency response system based on the principles of \"layered zoning, unified coordination, and clear responsibility allocation\". **The power supply companies in various counties and districts within the regional power grid, as well as electricity consumers, should develop emergency plans tailored to their specific circumstances, in order to prevent and handle emergencies and maintain normal operations in electricity production. ④ Focus on the key points. Adhering to the principle of \"unified coordination, protection of the main grid, and focus on key areas,\" in dealing with emergencies, the safety of the **regional power grid is given top priority, and all necessary measures are taken to prevent the expansion of the emergency. During the restoration of power supply, priority is given to restoring power to critical users in order to restore normal power supply conditions in society as soon as possible. 2. General principles for handling accidents: ① Rapidly contain the spread of the accident, eliminate its root causes, and remove threats to personnel, power grids, and equipment ； ②Do everything possible to maintain the operation of normal equipment in order to ensure a steady power supply for important users and plant operations ； ③Restore the decommissioned sections as soon as possible and put them into parallel operation ； ④Restore power to areas or users that have lost power as soon as possible, giving priority to restoring power to critical users ； ⑤Adjust the system operation mode as soon as possible to restore it to normal. IV. Scope of Application: This plan is applicable to the **region’s power grid in addressing and dealing with various types of emergencies that may have a significant impact on or pose a serious threat to the power grid. Chapter 2: Activation of the Plan I. Conditions for activating the plan: 1. **Failure and tripping of the main 220KV and 110KV lines in the regional power grid** ； 2. **Loss of voltage on 220KV and 110KV busbars at key stations in the regional power grid** ； 3. **Transformer tripping due to accidents at key stations in the regional power grid.** II. Reporting System: 1. The power grid dispatching system should establish a strict reporting system for emergencies as well as a seamless information network for such emergencies. **No unit or individual in the regional power grid shall conceal, delay reporting, or give false information regarding emergencies, nor shall they instigate others to do so. 2. In the event of an emergency or grid accident, the on-duty dispatcher shall report to the station/company’s supervising management and the provincial dispatching center. 3. In the event of an emergency or grid accident, the company’s senior management should promptly understand the situation of the accident and report the first-hand information accurately and truthfully to the relevant provincial company authorities. Chapter 3 **Emergency Response Plans for Regional Power Grid Incidents**
I. General Principles for Incident Handling:
1. In the event of a fault that causes a trip in 110KV and higher voltage lines: After the line trips and the load is transferred, it is necessary to control the load on other related lines and main transformers to prevent overloading. Decisions regarding whether to attempt to restore power should be made based on the specifics of the line fault. However, before attempting to restore power, the following factors should be considered: ① Select the appropriate point for restoring power – it is advisable to choose the switch located far from major power plants and central substations, as well as one that has a minimal impact on system stability ； ②The forced switching device should have sufficient breaking capacity; the relay protection system must be reliable; the number of times the switch is used to disconnect faults should remain within acceptable limits; automatic reclosing should be disabled ； ③The neutral point of the transformer at the high-voltage side must be grounded ； 2. Bus fault tripping: In a double-bus wiring configuration, in the event of a fault in one bus, it is necessary to check the components on the other bus, especially to determine whether the current flow through the main transformer is overloaded; the load current flow should be adjusted promptly to prevent overload. At the same time, quickly identify the cause of the fault; based on the findings, handle it in accordance with the following principles: ① If the faulty location can be identified and isolated promptly, restore power supply as soon as the fault is isolated ； ②If the fault location is identified but cannot be isolated quickly, and if a fault occurs in one of the two busbars, the intact components on the faulty busbar should be transferred to the non-faulty busbar to restore power supply ； ③When no fault point can be identified upon inspection, it is permissible to attempt to restore power to the busbar. The selection of the power source for this attempt should take into account the considerations that need to be addressed before attempting to restore power following a line fault trip. II. Accident Response Plan: 1. Power grid section: 1.1 In the event of a power outage due to a fault in the 220KV ** line: If the fault is permanent, under the unified command of the provincial power control center, the ** power plant will be connected via the 110KV ** line to form a 220KV–110KV electromagnetic loop network for operation ； The **line shall be powered from the medium-voltage substation, with the high-voltage substation in hot standby, and the 110KV line used as a backup for interconnection.** Make sure that the load on line ** does not exceed 80 MW; change the protection setting for line ** to that applicable to the interconnection line, but keep the protection system disabled. Chapter 4 Requirements for Plan Training and Drills I. Training: Based on the actual operating conditions of the power grid and the accident response plans, it is necessary to strengthen the training of technical personnel involved in grid dispatching, operation monitoring, and production management. Make full use of existing high-tech methods to train professionals in related fields, and improve the emergency response capabilities of various personnel through means such as simulations, thereby enhancing their ability to handle real-world situations. II. Drills: **Regional dispatching teams should take into account various unexpected factors such as weak points in the power grid, prominent operational issues, special operating conditions, severe weather conditions, external damages, and the characteristics of seasonal accidents. Regularly, targeted joint accident-response drills and exercises to handle emergencies should be organized, and thorough summaries should be conducted to continuously improve these drills; they must not become a mere formality. Chapter 5: Revision According to the \"Annual Operation Plan\" issued each year, and in light of any changes or adjustments in the grid’s operation mode, the \"**Regional Grid Emergency Response Plan**\" is revised to ensure its scientific validity and practical usability. Chapter 6 **Emergency Response Procedure Flowchart for Regional Power Grid Incidents: When a power grid incident occurs, the grid dispatch team is activated; a report is submitted to the relevant supervisor within the organization, as well as to the higher-level dispatch authority. The emergency response plan is put into effect, and reports are made to higher-level leaders. Immediate actions are taken to address the power grid incident. Once the incident has been resolved, an incident report is prepared, along with an assessment of the incident.**
