摘要
针对传统电力配电网络的接地故障电流控制问题,提出基于两相直挂式设备的配电网接地故障电流柔性调控。这一方法的主要特点包括简化设备结构、免供电、电压电流垂直原则、软并网和充电控制原则。通过Matlab仿真验证了这一方法的可行性,为改善电力系统的稳定性和可靠性提供了新思路。
In response to the problem of ground fault current control in traditional power distribution networks,a flexible control method for ground fault current in distribution networks based on two-phase direct mounted equipment is proposed.The main features of this method include simplified equipment structure,power free,vertical principle of voltage and current,soft grid connection,and charging control principles.The feasibility of this method was verified through Matlab simulation.This provides new ideas for improving the stability and reliability of the power system.
