摘要

在电力系统中，快速电压恢复对保持分布式发电机与系统的连接起着重要的作用。特别是在有大量电机同时运行的工业微电网中，这更具挑战性。在这方面，动态无功源的放置可以促进故障后场景下更快的电压恢复。本文将轨迹灵敏度指数(TSI)用于寻找静态同步补偿器(STATCOM)加速故障感应延迟电压恢复(FIDVR)的最优位置。仿真结果表明，基于TSI排序的STATCOM布局可以快速恢复系统中DG机组的故障后电压。

A Trajectory Sensitivity Index Based Approach to Accelerate Post-Fault Voltage Recovery in Microgrid

In a power system, fast voltage recovery plays an important role to keep the distributed generator (DG) connected to the system. Specially, it is more challenging in an industrial microgrid, where there is a large number of motors operating simultaneously. In this regard, placement of dynamic VAR sources can facilitate faster voltage recovery under post-fault scenarios. In this paper, trajectory sensitivity index (TSI) is used for finding optimal location of static synchronous compensator (STATCOM) for accelerating fault induced delayed voltage recovery (FIDVR). Simulation results demonstrate that STATCOM placement based on TSI ranking can quickly recover the post-fault voltage of DG units in the system.
