对可编程逻辑控制器(PLC)控制系统在实际应用中出现的温度信号显示不正常、模拟量信号漂移、开关量输入信号无反应、接地故障等干扰现象进行了分析

提出了解决方法及其防范措施

为电厂处理同类问题提供参考。

The interference phenomena occurred in practical application of the programmable logic controller(PLC) control system

such as abnormality in display of the temperature signal

shift of the analog signals

without response to input signals of switching value

and earth fault etc.

have been analysed

the solving methods and preventive measures being put forward

providing with reference for dealing with similar problems in other power plant.
