摘　　要：按照《防止电力生产安全重大事故的二十五项重点要求》,电力企业应设置主汽温度10 min内下降超50℃跳机保护,但是目前国内多数PG9171E型联合循环机组均未设置该保护。介绍了某厂Symphony Plus S+系统用多种方式搭建该保护,且对搭建过程和应用环境进行了阐述,为其他电厂Symphony Plus S+系统实现该功能提供参考和借鉴。According to the"Twenty-five key requirements for preventing major accidents in power production safety",power companies should set up the trip protection when the temperature of the main steam turbine drops over 50℃ within 10min.The case of a factory’s Symphony Plus S+system building this protection in a variety of ways is introduced,and the construction process and application environment are explained.This paper provides reference for other power plants to implement this function in the Symphony Plus S+system.
