本文提出了一种确定配电网络中最弱母线的方法。电压稳定性指示器（VSI）识别系统中最弱的总线。电压稳定性指标由辐射状配电系统的电压方程推导出来。通过放置 DSTATCOM 可以改善最弱的母线电压分布。 DSTATCOM 被建模为提供补偿所需的无功功率，并将 DSTATCOM 所在节点的电压幅度维持为 1 p.u。所提出的 VSI 和 DSTATCOM 建模的有效性通过标准 33 总线径向分布系统进行了检验。结果验证了大型配电系统中所提出的 VSI 和 DSTATCOM 模型。
This paper presents a method to determine the weakest bus in a distribution network. The voltage stability indicator (VSI) identifies the weakest bus of system. The voltage stability indicator is derived from the voltage equation of radial distribution system. The weakest bus voltage profile is improved by placing a DSTATCOM. The DSTATCOM is modeled to supply the required reactive power for compensation and to maintain the voltage magnitude of the node where DSTATCOM is placed as 1 p.u. The validity of the proposed VSI and DSTATCOM modeling is examined by a standard 33 bus radial distribution system. The results validate the proposed VSI and DSTATCOM models in large distribution systems.
