随着高渗透率分布式电源（Distributed Generation， DG）接入电网，对配电网故障场景下的供电恢复提出了更高的要求，研究配电网故障恢复可以提高配电系统的可靠性和稳定性。重合闸作为快速恢复供电的重要方法，其与分布式电源低电压穿越（Low Voltage Ride Through， LVRT）特性在时域上相配合可有效降低DG脱网率；故障场景下，柔性软开关的负荷转供和电压支撑作用能在保证用户供电的同时提高新能源的利用效率，降低新能源的脱网率。本文针对故障位置的两侧提出了不同的配电网的故障恢复方案，最后通过在MATLAB/Simulink仿真平台上搭建仿真模型证明了所提出的故障恢复方案的有效性与可行性。

With the integration of high penetration distributed generation into the power grid, higher requirements have been put forward for power supply recovery in distribution network fault scenarios. Studying distribution network fault recovery can improve the reliability and stability of distribution systems. As an important method for quickly restoring power supply, reclosing, combined with the low-voltage ride through characteristics of DG in the time domain, can effectively reduce the disconnection rate of DG; In fault scenarios, the load transfer and voltage support function of soft open point can improve the utilization efficiency of new energy while ensuring user power supply. This article proposes different fault recovery schemes for both sides of the fault location, and finally proves the correctness and feasibility of the proposed fault recovery scheme by building a simulation model on the MATLAB/Simulink simulation platform.
