摘要: 直驱风力发电机组穿越模型普遍缺乏实测验证,难以准确计算系统稳定裕度和精确分析故障响应。针对此问题,在分析二次侧故障穿越模拟原理的基础上,进行二次侧电压穿越模拟系统设计,利用最小二乘算法对波形数据进行辨识,并对模型进行验证。结果表明,相较于常规一次侧电压穿越试验,二次侧实测建模方法提高了试验效率,具有较高的仿真精度。

Abstract: It is difficult to calculate the system stability margin and analyze the fault response accurately because of the lack of experimental verification for the crossing model of direct-driven wind turbine. In order to solve this problem, based on the analysis of the principle of secondary-side fault crossing model, the simulation system of secondary-side voltage crossing is designed, the waveform data is identified by the least square algorithm, and the model is verified. The results show that compared with the conventional primary-side voltage traversal test, the secondary-side measurement modeling method improves the test efficiency and has higher simulation accuracy.

Key words: direct-driven wind turbine, voltage fault ride through, measurement-based modeling, secondary side simulation, parameter identification, model validation
