摘要： 在借鉴海上风电场实际项目经验的基础上，重点分析了海上风电场集电线路的等效方式以及海上风电场的等值建模。综合目前风电场动态等值中单机等值与多机等值的优缺点，以实际风电场作为参考，提出了单机等值法和多机等值法相结合的双层等效方法。按风机的馈线分布对风电场进行一次单机等值，再以主成分分析法对一次等值后的机组提取主导变量，作为二次多机等值的分群指标并进行机组分群，保证风电场等值的精确度。该等值建模对海上风电场进行二次等效建模，通过仿真验证，将等效后的仿真模型与实际详细模型做对比，验证了该等效方法的可行性。

Abstract: Based on the practical project experience of offshore wind farms, this paper focuses on the analysis of the equivalent way of collecting lines of offshore wind farms and the equivalent modeling of offshore wind farms. Based on the advantages and disadvantages of single-machine equivalence and multi-machine equivalence in the current wind farm dynamic equivalence, and taking the actual wind farm as a reference, a double-layer equivalence method combining the single-machine equivalence method and the multi-machine equivalence method is proposed. According to the feeder distribution of wind turbines, the wind farm is equivalenced for a single unit, and then the principal component analysis method is used to extract the dominant variables for the units after the primary equivalence. This is used as the grouping index of the secondary multi-machine equivalence and grouping the units to ensure the equivalence accuracy of the wind farm. The equivalent modeling performs secondary equivalent modeling for offshore wind farms. Through simulation verification, the equivalent simulation model is compared with the actual detailed model to verify the feasibility of the equivalent method.
Key words: offshore wind farm; line equivalent; principal component analysis; equivalent modeling.
