摘要：

摘要：Ｅ级燃气轮机发电机出口处的３只有功变送器所用电压互感器（ＰＴ）回路接线为同一组线圈电压，缺乏冗余度，一旦该组ＰＴ一次或二次回路断线，致使３只有功变送器输出的功率信号值同时出现较大波动，就可能引起跳机事故。针对以上情况进行分析，对该信号回路和逻辑进行改进，解决了配置引起的冗余度缺乏问题，提高了设备运行的安全性和可靠性。

Abstract:

Abstract:The circuit connections of potential transformer used by the three active transmitters at the outlet of E class gas turbine generator were the same set of coils voltage,and they were also lack of redundancy.Once primary or secondary circuit break happened in the potential transformer,it might lead to large fluctuations on output power signal values of the three active transmitters simultaneously.Furthermore,tripping accidents might occur.After a deep analysis and investigation of the above problem,the signal circuit and logic were improved.As a result,the lack of redundancy problem was solved,and the safety and reliability of equipment operation were improved as well.
