摘　　要：为了满足内蒙古电网黑启动试验仿真计算的要求,需要建立考虑黑启动孤网频率控制的水电机组模型。首先,使用PSCAD软件自定义搭建了万家寨水电机组模型,利用PSD-BPA软件验证了模型传递函数的正确性。然后,对调速器孤网模式控制参数进行了仿真优化。最后,基于实际机组甩负荷试验数据对水轮机模型进行了改进。基于上述模型对甩负荷试验进行了仿真反演,仿真结果与录波数据吻合度较高,证明了万家寨水电机组建模的准确性。In order to meet the requirements of black start test simulation of Inner Mongolia power grid, it is necessary to establish a hydropower unit model considering black start and isolated operation. Firstly, the model of Wanjiazhai hydropower unit is built based on PSCAD, and the correctness of the model transfer function is verified by PSD-BPA.Then, the control parameters of the governor isolated mode are simulated and optimized. Finally, based on the actual unit load rejection test data, the hydraulic turbine model is improved. Based on the above model, the simulation inversion for load rejection test is in good agreement with the recording data, which proves the accuracy of the modeling of Wanjiazhai hydropower unit.
