摘要(Abstract)：

浙能乐清发电有限责任公司多次发生脱硫热控系统测量信号受干扰显示异常的情况,通过分析查找,采用PLC程序进行干扰信号尖峰屏蔽和加装电容消除干扰。总结了软件抑制逻辑和加装硬件的简易处理方法及注意事项,可为干扰故障的快速处理提供参考。
There are abnormal signal display due to interfered measuring signal of desulfurization thermal control system in Zhejiang Energy Yueqing Electric Power Generation Co.,Ltd.By analysis and detection,interference signal peak sheldding by PLC programm and installation of capacitance are adopted for interference elimination.The paper summarizes software suppression logic and the simple treatment method as well as the precautions,providing reference to fast treatment on interference fault.
