摘要
本文介绍了羊卓雍湖三机式抽水蓄能电站的运行方式,着重分析了水力回流方式运行的必要性和经济性;扼要论述了电站的主要过渡工况的计算目的、数学模型,分析了计算结果。通过计算可以确定调压室的最高、最低涌浪,压力钢管沿线的最大、最小压力,分析事故机组或水泵起停对正常运行机组的水力干扰,验证电站调节系统的稳定性,提出合理的机组飞轮力矩值和调速器参数。
This paper describes the operating mode of Yangzhuo yong Lake Pumped Storage Power Station with the ternary units with stress on analysing the necessity and economy of operating mode in 'Water System Partial Circulating Current', briefly introduces the computation purpose of the main transition conditions, mathematic models, and analyses the computation results. In result, the maximum and minimum water levels in the surge tank and the maximum and minimum pressures in the penstock can be determined, the hydaulic interference of the emergency unit or starting/ stopping of the pump in normal operation analysed, the stability of the governing system of the station verified, and the reasonable flywheel moment value of unit and the parameters of the governor presented.
