| 摘要: |
| 针对海上风电场机组数量庞多、连接复杂造成的暂态同步稳定分析困难的问题，提出基于单机等效的海上风电场暂态同步稳定性直接分析方法。建立面向暂态同步稳定分析的海上风电并网系统模型；基于机组模型系数矩阵与电网节点阻抗矩阵的相似变换，建立系统单机等效模型，据此提出暂态同步稳定的直接分析方法。通过算例分析验证了所提方法的有效性，结果表明，基于所提方法可通过对单机系统的分析判定多机系统稳定性。 |

| Abstract: |
| Aiming at the problem of difficult transient synchronization stability analysis caused by large number and complex interconnection of offshore wind turbines, a direct analysis method of transient synchronization stability for offshore wind farm is proposed based on single-machine equivalence. The model of offshore wind power integration system is built facing the transient synchronization stability analysis. Based on the similarity transformation between unit model coefficient matrix and grid node impedance matrix, a system single-machine equivalent model is established, on this basis, a direct analysis method for transient synchronization stability is proposed. The effectiveness of the proposed method is validated by example analysis, and the results show that the proposed method can identify the stability of multi-machine system through the analysis of single-machine system. |
| Key words: offshore wind power transient synchronization stability single-machine equivalent model direct method equal area criterion |
