基于鲁地拉水电站枯水期耗水率动态分析的水库优化调度

Optimal Reservoir Operation Based on Dynamic Analysis of Water Consumption Rate in Dry Season of Ludila Hydropower Station

枯水期保证水库水位在1221m及以上的前提下,依据鲁地拉水电站近几年枯水期运行数据,综合分析耗水率与各变量之间的关系,将鲁地拉水电站水库优化调度问题,转化成了一个处理发电计划与耗水率相关关系的问题,形成一套“多退少补”的优化水库调度模式。得出鲁地拉水电站枯水期水库运行日动态调度相关关系:N_(t+1.日计划)=Q_(t-1.来)/μ_(t-1)+ΔW_(t-1)。

The requirement of guaranteeing reservoir water level in dry season is 1221m or above.According to operation data of Ludila Hydropower Station in dry season in recent years,the relationship between water consumption rate and various variables is comprehensively analyzed in this paper.The problem of reservoir optimal operation of Ludila Hydropower Station is transformed into a problem dealing with the relationship between power generation plan and water consumption rate,forming an optimum reservoir operation mode of"retreat more fill less".It is concluded that the correlation of dynamic operation of reservoir in dry season of Ludila Hydropower Station is N_(t+1.日计划)=Q_(t-1.来)/μ_(t-1)+ΔW_(t-1).
