摘要(Abstract)：

根据现场检查情况,对浙江省内主要火电机组汽轮机保护系统(ETS)的运行状况、硬件配置和定期试验等进行归纳分析,指出存在的故障隐患并提出相应改进措施。分析认为,目前ETS的系统电源、控制器通信、系统配置及试验模式等方面还有待进一步完善。
Through the summary and analysis of the operation condition,hardware configuration and regular tests of Emergency Trip System(ETS) for steam turbine of the main thermal units in Zhejiang province according to the field examination,papers points out the existing faults and hidden trouble and puts forward the improvement measures.It concludes the current ETS is still to be improved in respect of system power supply,controller communication,system configuration and test mode.
