基于辅助服务的机组无功优化分配

Optimal Distribution of Generator Reactive Power Based on the Auxiliary Service

建立了基于无功辅助服务的机组无功优化分配模型,并与等功率因素无功分配模型进行了比较。以二滩水电站机组为例进行了仿真分析,证明采用基于无功辅助服务的机组无功优化分配模型在满足机组安全、稳定运行的前提下,能够增加机组有偿无功辅助服务电量,提高机组经济运行水平,增加电站经济运行效益。

A generator reactive power optimization distribution model based on the reactive power auxiliary services is established, which is compared with the equal power-factor reactive power distribution model. The simulation analysis of Ertan hydropower station generator as an example proves that optimal distribution model of generator reactive power based on the auxiliary service under safe and stable operation, it can greatly increase the reactive power auxiliary service electric energy of generator, improve the level of economic operation, and increase the economic efficiency of power station.
