| 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. |
