水厂应用中的PLC所受的干扰源主要有电源系统引入的干扰、接地系统引入的干扰和输入输出电路引入的干扰三类。如果PLC的干扰问题解决得不好，系统将无法可靠运行，将会影响到正常供水。因此，有必要对PLC应用系统中的干扰问题进行探讨。主要本文分别讨论PLC的三种抗干扰技术。
电网的干扰，频率的波动，将直接影响到PLC系统的可靠性与稳定性。如何抑制电源系统的干扰是提高PLC的抗干扰性能的主要环节。
设置滤波器的作用是为了抑制干扰信号从电源线传导到系统中，使用隔离变压器，必须注意:屏蔽层要良好接地;次级连接线要使用双绕线(减少电线间的干扰)，隔离变压器的初级绕组和次级绕组应分别加屏蔽层，初级的屏蔽层接交流电网的零线;次级的屏蔽层和初级间屏蔽层接直流端。
为了抑制电网大容量设备起停(如送水泵等)引起电网电压的波动，保持供电电压的稳压，可采用开头稳压电源。
PLC的控制器与I/O系统分别由各自的隔离变压器供电，并与主电源分开，这样当输入输出供电断电时，不会影响到控制器的供电。
