PLC在电厂给水变频群控系统中的应用

The Application of PLC in the Power-plant Water Supply Inverter Control System

在热电厂给水系统的变频器群控系统,提出采用PLC来实现集中控制、频率分配、器件联动的设计理念,并在此基础上设计实施了一套基于PLC的可视化群控系统,最终实现了反馈响应最优化、运行参数实时化、节能效率最大化等预期目标。

In the power plant water supply system of the inverter control system, PLC is used to achieve the centralized control, frequency allocation, device linkage design concepts. And on this basis, a PLC-based visual control system is designed. Finally it is realized the feedback response optimization, operation parameters in real time, such as maximizing the expected target of energy efficiency.
