化学补给水控制系统改造方案介绍

Reconstructed Scheme of Control System of Chemical Feed Water

文中介绍了湖南省三个不同时期建设的电厂化学补给水控制系统改造方案,虽然三个不同时期电厂的化学补给水系统原有的控制水平不同,但都成功实现了PLC以太网的最终改造,且运行良好。虽然改造时要投入一部分资金与人力,但改造后的效果显著,大大提高了生产效率,因此这些改造方案比较适用于老电厂的扩建改造。

This paper introduces the construction of three different periods in Hunan chemical supply plant water control system improvement program.Although the chemical plant in three different periods of water supply control system at different levels of the original,but all successfully achieved end-PLC Ethernet transformation,and running well.Although the transformation of part of the time to put in money and manpower,but the obvious effect after the modification has greatly enhanced the efficiency of production,these reform programs more applicable to the expansion of old power plant transformation.
