摘要:
针对大规模双馈型机组所组成的风电场,提出1种将变桨机构动作情况作为风电场分群聚类指标的 等值建模方法。通过将能够表征变桨机构动作状态的特征向量输入到支持向量机中,对风电机组进行动态 分群,将同一群内的风机进行等效合并。此外叙述了等效机组参数计算方法,建立风电场多机等效模型。 经过对不同建模方法的比较得出,此方法在保证仿真精度的前提下大幅度缩小了仿真时间,且仿真结果更 加接近风电场实际运行工况,验证了该方法能够更加准确的表现出风电场并网点的动态特性。
Abstract:
For a large?scale wind farm with wind turbine driven doubly fed induction generator(DFIG). Put forward a kind of equivalent model method by pitch angle action situation as a cluster index. The specific method is,input the feature vector can characterization the state of pitch angle action in support vector machine. The wind turbines are dy? namically grouped,and the same group wind turbines are aggregated. The calculation method of equivalent wind tur? bine parameters has descried. Thus a wind farm model represented by multi?machine equivalent wind turbines is ob? tained. Through the comparison of different modeling methods,we can see the simulation time was reduced greatly in the premise of ensuring the accuracy of the simulation. And the result is more closed to the actual operating condi? tions of wind farm. Verified this equivalent model more accurately describes the dynamic characteristics of a wind farm at the grid connection point.
