湖北电网电源结构优化研究

三峡电站具有明显的季节性，而湖北电网水电比重较大（其中调节性能差的水电站占大多数），特别是湖北电网目前最大的水电站－葛洲坝水电站与三峡水电站年出力过程相同，在此条件下，若不采取有效措施，过多吸纳三峡电能将会影响湖北火电机的经济性、增大湖北电网的调缺缺口。

Study on Power Source Structure Optimization for Hubei Power Network

The output from Three Gorges power station has distinct seasonal difference and the ratio of hydro generator is comparatively high in Hubei province(most of them have bad regulating performance).Especially,the annual output process of Gezhouba hydro Power Station,the largest hydropower station in Hubei Power network is the same as that of Three Gorges.Under such condition,in case without taking any effective measure,the over accepting energy from Three Gorges will influence the economic performance of thermal power unit and enlarge the peak adjusting gap.
