| 摘要: |
| 以提高仿真效率为目的，建立了一种适用于永磁直驱同步电机风电场的多机动态等值模型。该模型在同调等值法的基础上，选择能综合反映风电机组运行状态的变量矩阵作为分群指标，通过模糊聚类算法对指标矩阵进行处理，将具有相近运行点的风电机组划分到同一机群。并用一台风电机组并联一个电流源组成等值机组表征该机群，最后通过多个表征机群的等值机组的组合建立了风电场动态等值模型。在此基础上，利用电力系统电磁暂态ATP/EMTP软件平台进行实例仿真，仿真结果验证了该等值模型的有效性。 |

| Abstract: |
| In order to improve the efficiency of simulation, a dynamic multi-machine equivalent model suitable for the wind farm equipped with direct-driven permanent magnet synchronous generators (D-PMSG) is presented. Based on the homology equivalent method, the matrix of variables that can comprehensively reflect the wind generators’ operation state is adopted as cluster classification index. Then, the wind turbines with similar operating point are divided into the same group by processing the index matrix with fuzzy clustering algorithm. The wind generators are represented by an equivalent wind turbine through a wind generator paralleled with a current source. Therefore, the overall equivalent wind farm model can be assembled with multiple representative equivalent wind turbines. Case study is carried out on ATP/EMTP platform and simulation results prove the validity of the proposed model compared with corresponding detailed model. |
