摘要
动静干涉与相位共振故障直接影响抽水蓄能电站水泵水轮机安全与稳定运行.本文以某水泵水轮机为对象,系统研究了由动静干涉产生的水力激振模式,并对其进行相位共振风险评估.通过实例计算分析了张河湾与黑麋峰抽水蓄能水泵水轮机由动静干涉引起厂房振动影响因素.同时,通过统计国内部分抽水蓄能电站水力参数,计算了动静干涉水力激振模式与相位共振风险系数RF,并提出相应预控措施.为其他大型抽水蓄能电站的振动问题提供参考,并为即将大规模建设的抽蓄电站安全稳定性提供积极借鉴意义.
Abstract
Rotor-stator interaction and phase resonance faults have a direct effect on the operation of the pump turbine of the pumped-storage power station.In this paper,the hydraulic excitation modes generated by rotor-stator interaction are systematically investigated with a hydraulic turbine as an object,and the risk of phase resonance is assessed.The influence factors of factory vibration caused by rotor-stator interaction of Zhanghewan and Heimifeng pumped-storage pump turbine are calculated and analyzed by examples.At the same time,by counting the hydraulic parameters of some pumped-storage power stations in China,rotor-stator interaction hydraulic excitating vibration mode and the phase resonance risk coefficient BF are calculated,and the corresponding pre-control measures are proposed.This provides a reference for the vibration problems of other large pumped-storage power stations and provides a positive reference for the safety and stability of the large-scale pumped-storage power stations to be built.
