针对某燃气机组紧急关断阀门（Emergency Shutdown Device，ESD）可靠性低的缺陷，分别从电磁阀配置、控制回路独立、电源冗余配置等方面进行改进： ESD阀选用24 V DC电磁阀，控制气路由单电磁阀改造为双电磁阀，并对电磁阀控制电源及调压站系统电源进行优化。ESD阀采用双电磁阀后，任何故障不会导致阀门误动；将双电磁阀分配到控制回路中，可同时对双电磁阀进行控制，从而实现了ESD阀的完全冗余。改进后，消除了跳机隐患，提高了系统的稳定性。
Abstract：The problem of low reliability of emergency shutdown device (ESD) valves of the gas turbine power plant is improved and solved from the aspects of solenoid valve configuration, independent control loop, and redundant power supply configuration. The ESD valve selects 24 V DC solenoid valve, upgrades single solenoid valve control to dual solenoid valve control, and optimizes solenoid valve control power supply and pressure regulation station system power supply configuration. The ESD of dual solenoid valve will not cause malfunction of the valve due to failure. By assigning the dual solenoid valve to the control loop, the dual solenoid valve can be controlled at the same time, so as to realize the redundancy and reliability of the ESD valve. After the improvement, the hidden danger of unit failure is eliminated, and the system stability is improved.
