| 摘 要： | 介绍了一种应用在低压配电网中的多功能无功补偿装置，采用16位单片机MC80C196KB为控制核心，设计了控制器的主电路。详细阐述了该装置测量采用的交流采样算法。对配电变压器电气参数进行实时监测、记录、统计和综合分析。采用零电压开关(晶闸管)实现电容器组的自动动态投切，消除了投切过程产生的涌流，减少了元件损坏和维护工作量。实现了无功补偿控制与配电变压器运行状态监测的综合功能。

| Abstract: | A multi-function var compensation controller for low-voltage power distribution network is introduced. Taking a 16-bit chip microcomputer as its core,the main circuit of the controller is designed. Its AC sampling arithmetic is presented in detail. The controller monitors and records the electric parameters of distribution transformer in real time,and does statistic calculation and comprehensive analysis. Capacitor groups are switched on-off dynamically and automatically by using zero voltage switch(thyristor),which eliminates switching inrush current and reduces com-ponent damage and maintenance workload. It integrates the functions of var compensation control and operation monitoring of distribution transformer. |
