摘　　要：本文设计了一种低压无功功率动态补偿装置。分析了动态补偿对电容器投切时间的要求,设计了投切信号发生电路,提出了提高补偿精度的电容器选择及组合方法,设计了电容器组投切策略,确定了补偿装置的硬件结构,同时设计了无功补偿控制方式流程图、电容器投切控制流程图等。基于本设计研制的无功补偿装置真正实现了动态补偿。This paper designs a low-voltage reactive power dynamic compensation device. The time requirement about dynamic compensation is analyzed,the switching signal generator circuit is designed,the selection and combination method of capacitors for improving the compensation accuracy are presented,the switch on-and-off strategy of capacitor bank is designed,the hardware structure of the compensation device is determined,the flowchart of reactive power compensation control method and the flowchart about capacitors switch on-and-off are designed. The reactive compensation device based on this design has realized dynamic compensation indeed.
