研究目的:本文对动态无功补偿进行研究,以解决在变配电所中静态补偿经常造成过补偿或欠补偿的问题,同时降低铁路供电线路的损耗,保证铁路供电系统的稳定性。
研究结果:动态无功补偿装置根据用电负荷的极性及运行过程中需要补偿的容量,可对并联电容器组等设备进行单独控制或者综合控制,实现变电所电压、无功的综合自动调整,从而实现提高供电电能质量、变电所无功就地平衡的目标。
Research purposes: The research is done on the dynamic reactive power compensation in railway substation for the purposes of solving the problem of over-compensation or under-compensation caused by static compensation in the substation, lowering the loss of railway power supply line and guaranteeing the stability of power supply system.
Research results: According to the pole of demand load and the compensated capacity required in the running process, the dynamic reactive power device can control the capacitor equipments individually and integrally for realizing comprehensively automatic adjustment of voltage and reactive power to improve the power supply quality and balance the reactive power in place.
