日调节水电站梯级经济调度系统的实现与应用

Implement and Alpplication of Cascade Economic Dispatch System in Daily Regulation Cascade Hydropower Stations

随着电力系统的迅速发展,日调节水电站在系统中承担的任务发生改变,对梯级联合经济调度的需求越发明显。以福建省富屯溪流域的三级日调节梯级水电站为研究对象,研究日调节水电站梯级联合调度模型,绘制、开发出日调节水电站联合调度图与相关的梯级经济调度系统软件,并且通过实际运行,达到梯级发电效益最大的经济目标,证明其具有经济、管理意义和推广价值,对其它类似梯级电站开展经济调度也有借鉴意义。

With the rapid development of electric power system, the tasks that daily regulation hydropower station groups undertake in the system have been changed. And the demand for cascade economic dispatch is becoming strong. By taking the three-stage daily regulation hydropower stations in Futunxi river basin in Fujian province as the research object, the article researches the cascade economic dispatch model of the daily regulation hydropower stations, drawing the joint dispatch chart of the daily regulation hydropower station and developing the related software system. Through the actual operation, the system achieves the goal of the maximum efficiency of cascade power generation. It is proved that the system implies economic significance, management significance and promotion value, and also has reference significance for the joint economic dispatch of other similar cascade hydropower stations.
