龙羊峡水电站增容发电量复核分析

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。

Reexamination and Analysis on Generating Capacity Increase of Longyangxia Hydropower Station

The generating capacity increase of Longyangxia hydrogenerator units is not only necessary but also probable.In order to find out the benefits brought by generating capacity increase,based on the dispatching chart of cascade hydropower plants,a mathematic model is established,an optimal arithmetic is adopted,six schemes are proposed,which reexamine and analyse the energy output.Via comparing indexes,such as average annual energy output ,average water head,assurance rate of electric power generation of each scheme and so on,the paper analyses the main reasons of energy output increment and draws the conclusion that the energy output increment benefits brought by generating capacity increase are evident .It provides technical references for the project execution of generating capacity increase of Longyangxia Hydropower Station.
