摘要
水泵水轮机最高扬程驼峰区安全裕度是抽水蓄能电站的关键参数,不仅仅关系到水泵水轮机高扬程抽水的安全稳定性,同时对水泵和水轮机总体性能,包括效率、入力、出力、空化、稳定性乃至过渡过程的稳定性均有重要影响。由于现有水泵水轮机规范和合同对该指标的要求过于严格,对总体性能产生了不利影响,为此提出建议,供相关电站参考。
The hump safety margin of pump turbine is a key parameter for pump storage station. Not only effect to the safety and stability of the pump turbine operating in the maximum pump head, but also influence the general performance of pump turbine operating on the pump mode and the turbine mode by efficiency, input, output, cavitation, stability and the transient process. As the requirements of the hump safety margin described in the national code and technical specification of the pump turbine are not fully reasonable, the proposal are given for owner consideration and taking, as reference for the relevant projects.
