Brief analysis of substation operation and maintenance Abstract This article introduces the importance of substation operation to safe power production, measures to ensure safe and stable operation of substations, as well as the professional qualities and work requirements that substation operators must possess. Keywords Substation operation safety In the operation of the power system, substation operation is the executive agency for power grid operation management, switching operation and accident handling. The main task of substation operation is the operation, maintenance and management of power equipment. It is characterized by a lot of equipment to maintain and a high chance of abnormalities and obstacles. ； The work is tedious and tedious, which can easily lead to mental laxity among personnel. ； The personnel are scattered and difficult to centrally manage. Each operation duty officer is the executor who ensures the safety, stability and economic operation of the power grid. In the operation and maintenance of the power grid, any irregular behavior may affect the safety and stable operation of the power grid, and even cause major accidents. If the power operation attendant performs the switching operation in the wrong position or mistakenly opens and closes the switch. will bring immeasurable economic losses and harm to families, businesses and society. * * Impact, because the safe operation of the power system largely depends on whether the safety level of the operation work can be grasped. As the backbone of the power system, the substation is the backbone of the power system. Once a fault occurs, it may affect the user's normal power supply and damage the equipment, causing economic losses. ； In severe cases, it will cause the power system to oscillate or collapse, causing large-scale power outages, endangering the safety of the power grid, equipment and people, and even bringing instability to society, affecting social stability, and posing a serious threat to the national economic construction and people's lives and property. In view of this, in order to effectively ensure the safe and stable operation of the substation, as the substation operation duty personnel, we must adhere to the policy of "safety first, prevention first", and must do the following in terms of ideology and professional skills. First of all, substation operation reflects the overall business level of the team. The procedures must be strictly followed. Procedures are written with lessons and blood, and their role in ensuring safe operation is very important. The team should not only emphasize familiarity with safety procedures, but also pay attention to the mastery and correct application of the procedures. The key to quality on duty is careful monitoring of screens, equipment inspections, shift inspections, class inspections, mental state on duty, etc. The quality of duty has been improved, accident handling can be responded to quickly, and the switching operation can be more accurate and faster. Because we have a clear picture of the operation mode, load conditions, equipment performance, etc. of the substation, we can organize and deal with it in a targeted manner. When an accident occurs, you will not be panicked and confused, such as: If you monitor the screen carefully, you will be able to fully grasp the signs before an accident occurs. ； If you inspect the equipment carefully, you will be able to grasp the operating status of the equipment. ； If the succession is taken seriously, equipment defects can be noticed or discovered in time, making the accident visible instead of invisible. Thus, accidents are nipped in the bud and the safe and stable operation of the power system is ensured. Secondly, in order to ensure the safe operation of the power grid, each person on duty must continuously improve their professional quality. This requires that on the one hand, the person on duty must have rich theoretical business knowledge, be familiar with the relevant laws and regulations in substation operation, master the "field operating procedures" and accident handling methods of substation operation, and be familiar with the simultaneous production process of power generation, supply and use. Ensure safe, economical and high-quality operation of the power grid ； On the other hand, they must have rich practical experience in operation. Each duty officer must be a conscientious person, learn by doing, learn by doing, and take practical measures to teach, help, lead, and follow new employees. * , self-study, take professional knowledge training classes ； Participate in on-site training and counter-accident drills * In a combined form, master the knowledge of all aspects of substation operation, accumulate experience, and use strengths and avoid weaknesses. ； For problems that you don’t understand or don’t know in practice, you must humbly learn from the experienced operators. * , until you understand and figure it out. Experience is constantly accumulated. Third, in actual substation operation work, whether it is daily work or abnormal accident handling, the on-duty personnel are required to concentrate and think diligently. Every operation must be accurate and various rules, regulations and procedures should be strictly implemented. Implement the "two votes and three systems" and always implement the policy of "safety first". In order to oppose * To avoid misoperation and ensure the safety of people and equipment, the on-duty staff should do this: 1. Check the simulation diagram before operation, carefully make various records, and fill in the operation ticket in time. After the operation is completed, check the simulation diagram to ensure accuracy, speed and accuracy. ； 2. Frequently check the operation mode, analyze the operation mode, and solve problems in a timely manner. Maintain safe and reliable operation methods, strengthen operation inspections, and ensure the normal operation of various equipment ； 3. Conduct frequent counter-accident drills * . Improve your ability to handle accidents and anticipate accidents under various operating modes, especially under special and weak operating modes. ； 4. Develop good labor discipline and maintain a good mental state. When performing switching operations, you must be fully attentive, concentrated, and emotionally stable. This requires the on-duty staff to enhance their sense of responsibility, take a good rest when they are off duty, and be able to concentrate on their work when on duty, and be able to think quickly when dealing with problems. For temporarily changed work plans and accidents and abnormal situations, we must carefully and carefully record the operation tickets and fill in the operation tickets in a timely manner. We must not deal with them based on impressions. ； 5. Establish and improve a normal inspection system, especially for important loads, special inspections should be carried out. Check transformers, metering devices, etc. If abnormal phenomena are found, make records in time and report to superiors ； Careful analysis should be done to find out the reasons. Ensure economical and stable operation of the power system. References: "Safety Work Regulations for the Electrical Industry" (Electrical Part of Power Plants and Substations) * * Industry standard.
