简述造纸PLC控制系统抗干扰分析：
一、概述
随着科学技术的发展，PLC（PLC的相关产品）在工业控制中的应用越来越广泛。PLC控制系统的可靠性直接影响到工业企业的安全生产和经济运行，系统的抗干扰能力是关系到整个系统可靠运行的关键。自动化系统中所使用的各种类型PLC，有的是集中安装在控制室，有的是安装在生产现场和各电机设备上，它们大多处在强电电路和强电设备所形成的恶劣电磁环境中。要提高PLC控制系统可靠性，一方面要求PLC生产厂家用提高设备的抗干扰能力；另一方面，要求工程设计、安装施工和使用维护中引起高度重视，多方配合才能完善解决问题，有效地增强系统的抗干扰性能。
二、电磁干扰源及对系统的干扰
1、干扰源及干扰一般分类
影响PLC控制系统的干扰源与一般影响工业控制设备的干扰源一样，大都产生在电流或电压剧烈变化的部位，这些电荷剧烈移动的部位就是噪声源，即干扰源。
