What is the Chinese translation of ESD\ITCC?

ESD emergency shutdown system, ITCC integrated turbine-compressor control system. Last edited by Compare on 2009-2-10 21:32.]

ESD is the abbreviation for Emergency Shutdown Device, which refers to the emergency shutdown system. This specialized security protection system was developed in the 1990s and has received unanimous praise for its high reliability and flexibility. 　　 The ESD emergency shutdown system, in accordance with the principle of safety independence, operates independently of the DCS distributed control system, and its safety level is higher than that of the DCS. Under normal conditions, the ESD system remains in a static state and requires no human intervention. As a safety protection system, it operates above the production process control to monitor the safety of the devices in real time. Only in the event of an emergency in the production equipment is it not necessary to go through the DCS system; instead, the ESD directly sends out protection interlock signals to safeguard the on-site equipment and prevent the spread of danger from causing significant losses. According to available data, people’s judgment and actions in dangerous situations are often delayed and unreliable; when operators are faced with a life-threatening situation, they must react within 60 seconds, and the probability of making a wrong decision is as high as 99.9%. Therefore, it is highly necessary to install safety interlocks that are independent of the control system; this is an important principle for ensuring safe production. It moves when it should move and stays still when it shouldn’t – this is a notable feature of the ESD system. 　　 Why is it necessary to have an ESD system set up separately? Of course, general safety interlock protection functions can also be implemented by a DCS. However, for larger-scale emergency shutdown systems, they should be installed separately from the DCS in accordance with the principle of safety and independence. There are several main reasons for this: (1) to reduce the likelihood of both control functions and safety functions failing simultaneously, so that a malfunction in the DCS does not compromise the safety protection system; (2) for large-scale installations or rotating mechanical equipment, the faster the response time of the emergency shutdown system, the better. This helps to protect the equipment and prevent accidents from escalating ； It also helps in identifying the causes of accidents and keeping records of them. Since DCS processes a large amount of process monitoring information, its response speed is difficult to make fast ； (3) The DCS system is a process control system that is dynamic and requires frequent manual intervention, which may lead to human-induced errors ； ESD, on the other hand, is static and does not require human intervention; by setting it this way, human errors can be avoided.

It would be even better if specific details and functions of ITCC could also be provided. I would be extremely grateful

The ITCC features an integrated turbine-compressor control system; GE uses MARK VI – I’m not sure if that’s the case

ESD is the abbreviation for Emergency Shutdown Device, which refers to the emergency shutdown system. ITCC is an integrated turbine-compressor control system.

The ITCC compressed air unit integrated control system (Integrated Turbine Compressor Control) is a new type of control system that has emerged in recent years, used for controlling compressed air units in large-scale projects. Compared with traditional compressor control schemes, it offers advantages such as high reliability, powerful functionality, flexible configuration, and ease of operation. It is a comprehensive control system that integrates turbine speed control, anti-surge control, performance control, load distribution control, extraction control, and self-protection interlock logic control for the entire unit. The ones that are widely used in China include ICS triplex and tricon.

Please provide specific details and functions of FGS

The function of ESDI is primarily used for safe logical interlock control. In addition to this function, ITCC also provides anti-surge control for the units, speed control for the turbines, and performance control for the units
