结合二滩电站历史运行数据,分析了500kV系统不同运行方式下的无功变化规律,为合理调整电站有功和无功功率分配,提高二滩电站无功经济运行效益提供了理论依据。
Combined with the historical operation data of Ertan Hydropower Station, the variation law of reactive power under different operation modes of 500kV system is analyzed, which provides a theoretical basis for adjusting the reactive power distribution of active and reactive power and improving the economic efficiency of Ertan hydropower stations.
