摘要
满发流量是水电站规划设计的重要参数,但其对梯级水电站发电量的影响却鲜有研究。以串联型梯级水电站为例,构建了梯级水电系统的数学模型和约束条件,给出了梯级水电系统的调度策略,通过实例仿真得出满发流量与梯级水电站发电量之间的关系曲线。结果表明,上级水电站的满发流量对下级水电站发电量的影响很小,梯级水电站的发电量主要受本级电站满发流量的影响。各级水电站的满发流量与其发电量之间的关系曲线态势相似,都存在一个峰值点。
The full-load flow is an important parameter in the planning of hydroelectric plant, but its effect on the whole output of cascaded hydroelectric plants are not been investigated. The mathematic model and its constraints are established by taking cascaded hydroelectric plants as an example. The scheduling policy has also been proposed. The simulation is carried out and the relation curves between the full-load flow and power generation are gained. The results show that the full-load flow of upstream plant has little effect on the downstream ones. The full-load flow mainly affects the power generation of the cascaded hydroelectric plant that it is related to. The curves between the full-load flow and the related power generation for each plant have some similarity that all of them have a maximum point.
