摘　　要：随着抽水蓄能电站数量的不断增加,其安全监控与管理就变得极为重要。抽水蓄能机组经常面临工况的急剧转换如突发事件甩负荷等,可能会给运行管理带来安全隐患。为此,基于李雅普诺夫稳定性理论提出了构建安全系统模型的安全阈值整定方法,并利用河北张河湾抽水蓄能电站的实际运行数据,对其进行了动态系统建模,完成了安全模型的构建及安全阈值的整定。将整定的阈值作为停机标准,对抽水蓄能机组实际运行参数进行动态实时监控,保证了机组安全平稳运行。As the number of pumped storage power station is increasing,the safety monitoring and management is extremely important.Pumped storage units faced with the rapid conversion of working conditions and unexpected events may trigger serious safety accidents.Based on the Lyapunov stability theorem,this paper presented a method of setting safety threshold by building system security model.Then the dynamical system model was established according to the actual operation data of Zhanghewan Pumped Storage Power Station,and obtained the safety threshold using the proposed method.Taking the threshold as the stop criterion,the actual running parameters of the pumped storage unit was monitored in real time to ensure the safe and stable operation of the unit.
