摘要
为了分析低水头、日调节或径流式水电站的出力情况,研究适用于水电站的发电调度运行方式曲线,笔者研究分析折线形和山峰形两种出力限制曲线,对两种曲线合理性进行分析和验证,并提出应用建议.结果表明,两种曲线均可以大幅提高水电站及电网调度对短期(日内)预想出力的预测精度.两种曲线均可适用于低水头、径流式水电站在不同水头条件的调度需求,有一定借鉴意义.
Abstract
In order to analyze the output of low head,daily regulation or run-of-river hydropower station,and study the operation mode curve of power generation scheduling suitable for hydropower stations,the authors study and analyze two output limit curves of polygonal-shape and peak shape,analyze and verify the rationality of the two curves,and put forward application suggestions.The results show that the two curves can greatly improve the prediction accuracy of hydropower station and power grid dispatching for short-term(intraday)expected output.The two curves can be applied to the scheduling requirements of low head and run-of-river hydropower stations under different water head conditions,which has certain reference significance.
