摘　　要：针对矿井电网负荷变化频繁、无功冲击大的特点,设计了一套机械投切电容器(Mechanically Switched Ca-pacitor,简称MSC)动态无功补偿系统。该系统首次将高压真空接触器实际应用于投切并联电容器组,利用高压真空接触器寿命长、操作频繁、价格低的优势打破了晶闸管触发投切的传统惯例。选用DSP作为核心控制器,对电容器组进行选相投切,并利用神经网络的学习和训练功能避免产生接触器过电压和涌流现象。相对传统动态无功补偿装置而言,此系统具有可靠性强、损耗少、成本低的优点,给企业和国家带来了巨大的经济效益。For mine power load change frequently and impact large,a set of dynamic reactive power compensation system mechanically switched capacitor（MSC） is designed.It is the first time to use high-voltage vacuum contactor in switching capacitors.Its advantages of long life,frequent operation and low price break the traditional practice of thyristor trigger.It takes DSP as the core controller,which control vacuum contactor to switch capacitors.Meanwhile,it uses learning and training function of neural network to avoid over-voltage and surge phenomena.The system is more reliable,and has lower loss and cost comparing with to the traditional dynamic reactive power compensation device.It will bring huge economic benefits to business.
