| 摘要: |
| 随着应用场合的不同，风电场模型参数需要相应改变。现在主流的风电场大多采用双馈式风机，而双馈式风机模型中PI控制器参数修正问题少有文献谈及。针对此问题，在PSCAD/EMTDC仿真平台下，忽略风机启动的暂态过程，转子侧、网侧变流器分别采用定子磁链定向、电网电压定向控制策略，建立了转子侧、网侧变流器均采用SPWM调制的直接功率控制模型。给出了基于传递函数的控制器参数整定方法,适用于双馈式风机的控制器参数的修正。模型详细参数采用GE1.5 MW双馈式风机组成的风电场模型参数。与Matlab/Simulink下仿真结果对比可知，该整定方法取得了较理想的效果，在两个仿真平台中输出参量具有较好的一致性。 |

| Abstract: |
| In different applications, wind farm model parameters need to modify simultaneously. Nowadays, doubly-fed induction generators are widely used in previous wind farm. Proportional integral controller parameters modification are rarely mentioned in the past paper. To solve the problem, a wind farm model is built in PSCAD/EMTDC simulation environment in this paper. In the model, transient process of doubly-fed induction generator is ignored. Stator flux orientation and grid voltage orientation strategy are used respectively in rotor-side converter and grid-side converter. Direct power control model with SPWM modulation are used in both rotor-side converter and grid-side converter. The controller parameter determination method is based on transfer function. The model can be a resolution on controller parameters modification problem. GE 1.5 MW doubly-fed induction generator parameters are used in the model. Comparing simulation results with that in Matlab/Simulink platform, the controller parameter determination method has got an ideal effect. The output parameters are of certain conformity. |
