水泵水轮机主要参数选择对机组运行稳定性的影响分析

Analysis of the Influence of Main Parameters Selection of Pump-turbine on the Stable Operation of the Pump Storage Units

水泵水轮机主要参数的选择对机组运行稳定性的影响尤为重要,且能够对机组运行稳定性造成影响的参数较多,为探寻不同参数对机组运行稳定性的影响,本文根据已建和在建项目的运行情况和模型试验结果等经验,通过公式拟合等手段为新建机组推荐合适的参数选择,减少前期设计的不确定性,为今后抽水蓄能前期设计工作提供一定借鉴,为将来新建机组的稳定性打下基础。

The selection of the main parameters of the pump turbine has a particularly important impact on the stability of the unit operation,and there are many parameters that can affect the stability of the unit operation.To explore the impact of different parameters on the stability of the unit operation,this article recommends suitable parameter selection for new units through formula fitting and other methods based on the operating conditions and model test results of existing and ongoing projects,reducing the uncertainty of preliminary design,To provide certain reference for the preliminary design work of pumping and storage in the future,and lay a foundation for the stability of new units in the future.
