大型汽轮发电机组进相运行及对电网调压试验研究

Study on leading phase operation and voltage regulation test of power network for large steam turbine-generator

介绍了300、600MW大型汽轮发电机进相运行的限制因素及对电网电压的调整效果。试验分析表明,大机组发电机进相运行可有效改善电网无功潮流分布,提高电网供电质量。电网调度部门可根据系统电压情况通过实施发电机进相运行来调整电网电压,其电压调整为1%～5%。

The limiting factol.s of 300 MW, 600 MW large steam turbine-generator leading phase operation and the effects of voltage regulation on power network were presented. The analysis indicates that large turbine-generator leading phase operation can improve the reactive power load distribution and the quality of power supply effectively. The dispatching departments can regulate the power network vohage by generator leading phase operation, and the adjustment range is 1%-5%.
