A Microcomputer Control System for Compensating Reactive Power with Thyristor

介绍一种适用于低压配电网基波无功补偿微机控制系统，设计了一种简便的基波无电流快速检测硬件电路。该系统能实现对多级电容器组的分相投切控制，可满足低压配电网基波无功补偿的快速性和实时性要求。

A microcomputer control system, which is suitable to compensate reactive power in low-voltage networks, is described. A simple and effective circuit for detecting fundamental-wave reactive current is presented. Using this System, separate-phase control of the switched capacitors can be realized. The fast and real-time compensating characteristics can be obtained with this system on compensating the fundamenta-swave reactive power in low-voltage networks.
