戈兰滩水电站水位流量关系分析

The Analyze of Water Level-Discharge Relation of Gelantan Hydropower Station

以戈兰滩水电站预可研、可研设计阶段水位流量关系分析计算为例,阐述了有、无实测流量资料条件下,水位流量关系低水部分拟合、高水部分外延的多种计算方法,总结了多种成果比较与合理性分析的重要性,尤其是在结果有差别时,不同的优选成果对水轮机选型、施工导流规模等的设计有较大的影响,进而影响水电站的效益。因此,如何确定可靠的水位流量关系显得十分重要。

In this paper,many kinds of calculation methods are intreduced,such as water lever-diseharge relations fit at lower water level and extend externally at high water level under the condition that whether there are real tested discharge data existed taking the analyze and calculation of water level-discharge relation at the beforehand feasibility study,feasibility study and design stage as example.It summarized the comparison of many kinds of results and the importance of reasonably analyzed.Especially under the condition that some difference in the results are existed,the different optimized results have great influence to selection of turbine,the scale of construction diversion and moreover, it will influnce the beneficial result of the power station.Therefore.it seems that how to determine reliable water level-discharge relation is very important.
