摘要
为研究龙滩水电站700 MW水力发电机组转轮运行的综合性能,采用三维湍流数值模型对转轮进行了数值计算和性能预估。通过数值计算结果与试验结果的对比分析,为龙滩水电站转轮在各工况尤其是低水头工况的安全稳定运行提供了参考依据,并提出了改善机组稳定运行的建议和优化措施。
In order to study the runner properties of Longtan 700MW hydroelectric generating unit, numerical calculation with 3D turbulent numerical model is made and performances of the runner are estimated. The analysis on numerical results and experimental results provides references to the safe and stable operation of the runner under all working conditions, especially the low-head condition, and proposes optimization measures to improve operation stability of the unit as well.
