Multi-Mode Coordination System Control Strategy And Its Operation Performance Of Western Nanjing Power Grid Upfc Project

As the latest generation of FACTS devices, Unified Power Flow Controller (UPFC) can control the system voltage and power flow rapidly, precisely and continuously, which provides an effective means to solve the restrictions on urban power gird development. This paper studies in UPFC system control strategy, which is the direct link and core problem of application. And a multi-mode coordination system control strategy is proposed in this paper, which can optimize the power flow distribution under different operating condition of power gird. Combining with Western Nanjing Power Grid UPFC project commissioning, the actual control effect in the power gird of the strategy are given, it provides practical experience for the popularization and application of UPFC.
