建立了风电机组和超导储能（ superconducting magnetic energy storage ，SMES）装置的数学模型以研究SMES对并网风电场运行稳定性的改善。针对风电系统中经常出现的联络线短路故障和风电场的风速扰动，提出利用SMES安装点的电压偏差作为SMES有功控制器的控制信号的策略。并搭建了风电场接入电网后的仿真模型，对实例系统进行的仿真计算结果表明，SMES采用该控制策略，不仅可以在网络故障后有效地提高风电场的稳定性，而且能够在快速的风速扰动下平滑风电场的功率输出，降低风电场对电网的冲击。

The mathematic models for wind power generator and superconducting magnetic energy storage ( SMES) unit are set up, and the function of SMES in improving the operation performance of wind farms is then studied .According to the short -circuit fault in the grid and wind disturbance of the wind farms often occurred , a new strategy using voltage deviation of SMES connection point as control signal of the active power controller of SMES unit is presented .A simulation model of the power system connected with wind farm is established .The simulation results show that with the designed controller , SMES can not only improve the transient stability of wind power system after the short circuit of the grid , but also effectively smooth the out-put of wind farm and reduce the impulsion to power system during the fast wind disturbance .
