摘  要:在特殊时期电站需要进行生态调度满足下游河道的生态需求,为合理评价与制定电站短期生态调度过程,以景洪电站为例,分析其1956~1987年3~8月份逐日水文数据,分别构建各月流量与涨落水率模糊集隶属函数,采用模糊集相似度概念作为衡量电站调度效果的标准。提出了一种基于天然水文资料的电站日内优化调度方法,发现相对于原调度方案,经优化后的生态调度方案流量和涨水率的变幅与天然水文过程更加接近。优化结果显示,在枯水期优化方案相对于原方案日内下泄总量有一定减少,在丰水期优化方案相比于原方案日内下泄总量增幅较大。研究成果可为电站短期生态调度的评价和优化提供参考。The power station needs ecological scheduling to meet the ecological demand of the downstream river in special periods. The daily hydrological data of Jinghong power station from March to August 1956 to 1987 were analyzed, and the vague set affiliation functions of flow rate and rising and falling water rates were constructed for each month separately, and the concept of similarity of vague sets was adopted as a criterion to measure the dispatching effect of the power station. An intra-day optimal dispatching method of the power station based on natural hydrological data was proposed. It is found that the variation of flow and rise and fall rate of the optimized ecological dispatching scheme is closer to the natural hydrological process compared with the original dispatching scheme. The optimization results show that the optimized scheme has a certain reduction in the total intra-day discharge during the dry period compared with the original scheme, and a larger increase in the total intra-day discharge during the wet period compared with the original scheme. The model can provide theoretical reference for evaluation and optimization of short-term ecological dispatch of power plant.
