| 摘 要： | 为了减小10kV配电网投切无功补偿电容器组时所产生的开关暂态过电压对电力设备造成的危害，提出了一种基于DSP的采用同步技术投切无功补偿电容器组的控制装置。该装置以数字信号处理器（DSP）TMS320LF2812为核心，对交流电压、电流同步采样，实时提取三相电压、电流的零点，控制同步真空断路器实现补偿电容器组在电压过零时投入，在电流过零时切除，有效减小投切电容器组时所引起的涌流和过电压，弥补了传统无功补偿装置存在的不足。

| Abstract: | order to reduce the 10kV power distribution network switching and reactive power compensation capacitor of switch transient over-voltage on the harm caused by electrical equipment, introduced a DSP-based synchronization technology used switching reactive power compensation capacitor control device. The installation to a digital signal processor (DSP) core, TMS320LF2812 voltage, current, real-time synchronous sampling, extraction of three-phase voltage and current of zero, the control of synchronous vacuum circuit breaker in the realization of compensation capacitor voltage zero inputs, in the current zero, effectively reducing the capacitor when inrush and over-voltage traditional reactive power compensation equipment. |
