摘　　要：详细推导出了抽水蓄能电站背靠背启动过程的数学模型，利用解耦的方法使得发电机与电动机的状态方程可以分别进行数值计算。模型中考虑了发电机和电动机两机的容量比、励磁电流比、初始相位角和水轮机导叶开度及导叶开启速度对背靠背启动的影响，编制了其通用计算机仿真软件，给出了数字仿真的计算结果。This paper presents a new mathematical model for back to back startup of pumped storage hydro units in detail.Using decoupling method,the state equations for both generator and motor can do numerical calculation individually.The effect of generator to motor capacity ratio and excitation current ratio,initial phase angles,opening and opening rate of wicket gate of the hydraulic turbine on the back to back startup are taken into consideration in the model.A general purpose computer simulation software is prepared,and the calculation results for digital simulation are also presented.
