摘要
相比于交流电网系统,直流电网系统拥有更为广泛的应用前景,但目前相关的技术研究尚处于起步阶段。为解决直流电网系统出现故障时导致的供电质量和供电可靠性下降的问题,针对直流配电系统接地故障展开分析,研究出现交流电源侧故障、直流网络故障、负荷侧故障时的电流电压变化情况,采用仿真模拟软件建立不同接地方式,对直流配电系统的故障量进行研究。研究成果可为直流电网的运营和维护提供理论依据。
Compared with the AC power grid system,the DC power grid system has a wider application prospect,but the current related technical research is still in its infancy.In order to solve the problem that the power supply quality and power supply reliability decline caused by the failure of the DC power grid system,this paper analyzes the ground fault of the DC power distribution system,and studies the current and voltage changes in the occurrence of AC power side faults,DC network faults,and load side faults.In different situations,simulation software is used to establish different grounding methods,and the fault quantity of the DC power distribution system is studied.The research results can provide theoretical basis for the operation and maintenance of DC power grid.
