首先介绍了STAR-90仿真平台,然后详细描述了抽水蓄能电站中水泵水轮机数学模型、发电/电动机数学模型及励磁机的数学模型。文中讨论了抽水蓄能电站调节控制模型,其分为限时调节控制方式和限压调节控制方式,并介绍了抽水蓄能电站各种运行工况以及它们之间的转换。最后在STAR-90仿真平台上运行得出仿真结果,该结果基本符合现场的运行工况,完全满足抽水蓄能电站运行人员的培训要求。
Firstly, the STAR-90 simulation platform is introduced. Then the mathematic model of pump-turbine mathematical model, generator / motor model and exciter model are described in detail. The control model of pumped storage power station is discussed in this paper. The control model is divided into time-limited control mode and pressure-limited regulation control mode. Various operating conditions of pumped storage power station and the transition between them are introduced. Finally, the simulation results are obtained on the STAR-90 simulation platform. The results are basically in line with the operating conditions of the site and fully meet the training requirements of the operators of pumped storage power stations.
