PLC 控制系统的抗干扰能力是关系到整个控制系统安全运行的关键因素之一，而接地系统是PLC安装和应用过程中的重要环节。针对PLC控制系统中存在的干扰问题，重点探讨了系统接地类型、方式及接地装置。实际结果表明，采取良好的接地措施，对提高PLC控制系统的抗干扰能力。

引言    

   随着国民经济的快速增长，国家智能电网计划建设更多高参数、大容量的燃煤火电机组，以满足不断增长的电能需求。高参数、大容量燃煤火电机组的辅助PLC控制系统的控制结构和控制范围发生了巨大的变化，因此，对控制系统的可靠性要求更为严格。

   PLC系统的抗干扰能力已越来越受到人们的重视。合理、可靠的系统接地是提高控制系统抗干扰能力的重要保证。为了保证PLC控制系统的监测控制精度和安全、可靠运行，必须从设计、设备的选型和安装、调试、生产维护各个环节对PLC控制系统的接地进行控制。本文就多个PLC控制系统现场实际应用的情况，探讨了如何通过完善PLC控制系统的接地来提高系统的抗干扰能力，从而实现系统的安全运行。

一、干扰的产生

   PLC控制系统应用现场的干扰源种类繁多，尤其是大型电厂更为复杂。干扰的来源主要包括以下几个部分。

   ①PLC控制系统内部

   PLC 控制系统内部干扰源主要有元器件的固有噪声、电源系统等。 

   ②PLC控制系统外部 

   PLC控制系统外部干扰源主要有闪电、雷击、电气设备的电磁场、电火花等。 

   ③PLC控制系统和周围其他系统的电位差等

   在PLC控制系统和周围其他系统的电位差等干扰中，有些干扰源有规律可循，可以通过一定的手段检测并加以控制；有些干扰源则随机出现，难以捕捉。但各种干扰源都是通过一定的途径对控制系统产生影响的，这些干扰途径主要是以“路”或“场”的形式出现。 

   1.1 “路”的干扰

   “路”的干扰是指干扰通过电路（主要是控制系统的过程通道或电源系统）进入PLC控制系统。A/D、D/A转换设备和各种输入装置都有可能成为各种干扰的通路。另外，过程通道和PC计算机之间的公共地线也会成为干扰通路。

   “路”的干扰分为串模干扰和共模干扰。

   串模干扰是指干扰信号叠加在输入信号上的一种干扰方式。这种干扰信号的特点是它与输入信号串联，存在于同一个回路中，并且全部施加在接收被测信号设备的输入端。干扰信号可能是信号源内部产生的，如图1(a）所示；也可能是由导线感应进来的，
