不对称急剧波动负荷供电的无功补偿和微机控制

The Var Compensation in the Power Supply Network toUnbalanced and Fast-varying Industry Loads and theComputer Control System in a Compensator

本文导出了三相不对称急剧波动负荷供电线路动态无功补偿规律(模型)的三种形式,并依据其第三种补偿模型,为TCR型静止无功补偿器设计了微机控制系统,介绍了系统的硬件和软件,提供了初步实验结果。

This paper derives shortly three kinds of models of var dynamic compensation in the power supply network to unbalanced and fast-varying industry loads. To be based on the third kind of models, a computer control system with a monolithic processor in a static var compensator of TCR type has been constructed. Hardwares and softwares of the control system are also illustrated in this article. Some results of a tentative test are presented.
