摘　　要：发电机进相运行是解决系统低谷运行时枢纽点电压偏高的有效手段。针对江苏省2010年实际背景分区电网,选择若干组已投运的机组,以分类分区研究单机进相的调压作用为基础,对多机进相运行进行仿真,分析进相运行对分区关键母线电压的影响和对系统电压的调节作用,并校验多机进相运行时系统的暂态稳定性,探讨分区内多机进相运行的调压能力。Leading phase operation of generators is an effective method to reduce voltage of the key point which is much high in valley load period.Several generating units in operation in the district grid of Jiangsu province in 2010 were selected as the research targets.Then the research analyzed the influence of leading phase of multi-generators on the key bus voltage based on the voltage regulation effects of leading phase of single-generator in classification and subarea method.The transient stability of leading phase of multi-generators was verified,and the voltage regulation capability of leading phase of multi-generators was analyzed.
