摘　　要：为了满足就地随机补偿的要求,提出一种自关断器件控制的电容器(SDCC)无功动态补偿装置。对调整电容器电压的无功功率动态补偿电路原理进行了论述,采用反向阻断器件组成开关电路,由开关电路调整补偿电容器的充放电电压,实现用电容器对负载无功功率补偿的动态控制。用实例对调整电容器电压无功功率动态补偿电路中的工作原理、工作过程和主要器件参数的选择进行了分析和阐述。经样机验证SDCC无功动态补偿装置可满足就地随机补偿的要求。A self-switch off devices controlled capacitor （SDCC）reactive power dynamic compensa- tion device is proposed to meet local random compensation. The circuit principle of reactive power dynamic compensation for adjusting capacitor voltage is described. The switch circuit consisting of reverse blocking device is adopted to adjust the charge and discharge voltage of compensation capaci- tor and achieve the dynamic control of load reactive power compensation by using capacitor. The working principle and process for adjusting reactive power dynamic compensation of capacitor voltage as well as selection of main elements parameters are analyzed and described by example. It is veri- fied by the sample that SDCC reactive power dynamic compensation device can meet the requirement of local and random compensation.
