摘　　要：该文通过对配电网系统中中性点不接地时断路器投入电容器组分别在峰值和过零点进行了仿真分析,给出了配电网同步关合的控制策略,阐述了同步合闸过程,并对同步关合的关键技术进行了研究。采用remez算法的FIR工频数字滤波器对信号进行调理,避免了谐波对提取过零点的干扰。分析了控制电压与环境温度分别对断路器分合闸的影响,并采用线性插值法对机构的动作时间进行补偿。Based ontheneutralpointungrounded systemofdistributionnetwork,synchronousswitchofcapacitor is simulated and analyzed in the peak and zero crossing point,the synchronization control strategy ofdistribution network is given and the process of which is represented,the key technologies of synchronous closing has been studied.The signal would be conditioned by using FIR digital filter with remez algorithm,to avoid the harmonic extraction of zero interference.the Influence of the control voltage and temperature in circuit breaker closing isanalysed,and thelinearinterpolationmethod would beused to compensate the agency action time.
