摘要
以龙羊峡水电站为背景,采用遗传算法建立了水电站调度模型,并在此基础上评估了龙羊峡水电站低水位运行所带来的发电损失,研究结果表明:龙羊峡水电站在实际调度中,低水位情况下超发电量现象十分严重,致使耗水率平均偏高达34.36%,严重影响了水电站的长期运行效益。如果能恢复到正常水位下运行,每年可平均提高发电量63.7%,并使耗水率降低29.2%。
In this paper,according to the practical condition of the Longyangxia Hydroelrctric Station, an operation model of hydroelectric station is proposed based on the genetic algorithm, and the loss of electric energy of operation under low waterlevel is estimated using the model. The results show that the exaggerated generation is severe in Longyangxia Hydroelrctric Station, and water consume rate increases by 34.36%. This phenomenon influences economic benefit greatly. If the water level can be raise to normal level, the average increased electric generation is (63.7%), and the water consume rate can be decreased by 29.2%. These outcomes provide some valuable reference about the raising water level for the operation of Longyangxia Hydroelrctric Station.
