无功补偿自控方案在电力设计中的应用比较

Application of the Reactive Compensation Self-Control Program in Power Design

简述了无功补偿的原因和意义、补偿途径和方式。研究了传统电子式自动补偿控制方案、基于单片机控制技术的无功补偿自控方案以及基于PLC控制技术的无功补偿自控方案等设计结构和原理。并对其性能和电路结构特点进行比较,为电力设计提供参考。

This article firstly presents the cause,significance,means and ways of reactive power compensation.Then it introduces the design structure and principle of the traditional electronic automatic compensation control system,the auto-controlling system of reactive power compensation based on the SCM control technology and the auto-controlling system of reactive power compensation based on the PLC control technology.Finally,the author compares the three control systems and their circuit structure features to provide a reference for electric power design.
