龙羊峡水电站机组具有增容的必要性和可能性.为探求电站增容后产生的效益,以梯级水电站调度图为依据,建立数学模型,采用优化算法,拟定6种方案,进行电站增容发电量复核分析.通过比较各方案的多年平均发电量、平均水头和发电保证率等指标,分析电量增加的主要因素,结论是电站增容后产生的电量增值效益是明显的,这可为电站增容项目的实施提供技术参考.
The necessity and possibility of capacity expansion of Longyangxia Hydropower Station are explored.In order to find out the benefit of power station after capacity increase, a mathematical model is established on the basis of the schedule map of cascaded hydropower station, and six kinds of schemes are formulated by using optimization algorithm to increase capacity of power station Analysis of generating capacity The main factors of increasing electricity consumption are analyzed by comparing the annual average generating capacity, average water head and generation guarantee rate of various schemes, etc. The conclusion is that the value added benefit of generating electricity after capacity increase is obvious, which can be used for power station The implementation of capacity expansion projects provide technical reference.
