摘    要:针对某些配电网负荷电压水平不满足要求和电压波动较大的问题,提出基于串联电容补偿的配电网负荷电压调节与稳定方法.通过在配电线路上串入可调电容,根据电容电压损耗与线路原电感电压损耗极性相反的特征,在负荷波动的情况下利用电容电压抵偿线路电感电压即可调节和稳定负荷侧电压.通过实时采样负荷功率,计算补偿电路的晶闸管触发角,调节电...

关 键 词:配电网  串联电容补偿  调压  晶闸管  仿真

Abstract:The series capacitance compensation is applied to realize the load voltage adjustment and stabilization for those distribution power systems which have large voltage fluctuation or could not meet the requirement of load voltage level.The adjustable capacitor is inserted into the distribution line and its voltage is used to compensate the line inductor voltage when load fluctuates,which could adjust and stabilize the voltage.The load power is sampled and the thyristor trigger angle of compensation circuit is...
Keywords:distribution power system  series capacitance compensation  voltage adjustment  thyristor  simulation
