摘要
通过AB公司的ControlLogix PLC系统在浙江某电厂水务控制系统的应用案例,着重介绍PID指令对加药工艺过程自动控制,论及PID指令的调节参数设置经验方法。
Along with the development of technology and management, the entire automation becomes important in power plant. Generally, the automatization can be actualized by using the programmable controller （PLC） for auxiliary control system in power plant. This article mainly elaborated the application of ControlLogix PLC system in one power plant in Zhejiang. The PID adjustment for the automatic chemistry control system is emphasized, and finally an experience way of setting the PID parameter is introduced.
