摘要
在传统9区图的基础上改进了智能控制策略,设计一种以SM8958A单片机为核心构成的智能型动态无功补偿控制器.应用CD4070构成功率因数采集电路保证对功率因数的准确采集.采用智能投切判据和投切算法使电容器组的投切更加合理,投切无震荡,避免电容器组的频繁投切.经过现场的实际运行,本控制器实现了对无功功率的动态补偿.
The intelligent control strategy is improved on the basis of the classic ＂nine-zone＂ theory. A kind of intelligent Dynamic and Reactive compensation-controller is designed by using single-chip microcomputer SM8958A. The accurate acquisition of power-factor is achieved by acquisition circuit using CD4070. More reasonable switching of capacitors is achieved by using intelligent switching algorithm and criterion in order to avoid frequent switching of capacitors. The dynamic compensation of reactive-power is achieved by this controller through practical local operation.
