| 摘 要： | 以双馈感应发电机组构成的风电场为研究对象,考虑了风力发电机与集电网络的等值,提出两种模型,研究了单机加权等值与等功率损耗结合模型,降阶变尺度等值与并联化结合模型。针对风电场机组参数完全相同的算例,利用PSCAD/EMTDC建立了风电场的不同等值模型,对风速扰动和PCC处发生电压跌落故障下的风电场暂态特性进行了比较分析,研究结果验证了等值模型的正确性。 |

| Abstract: | The thesis focuses on wind farm consisting of doubly fed induction generators, considering the equivalence of wind power generator and collector network, put forward two models, study the combination model of single weighted equivalent and equivalence power loss, the combination model of reduced-order re-scaled and parallel connection aimed transformation. Regarding the wind turbine generator system with identical parameters, using PSCAD/EMTDC to establish the different equivalent model of wind farm, a comparative analysis of the transient characteristics of wind velocity perturbation and the voltage drop of PCC, the results verify the validity of the equivalent model. |
| Keywords: | wind farm doubly fed induction generator equivalent model collector network |
