可再生能源与电力系统的整合带来了一些技术挑战，包括为系统保护研究开发适当的模型和准确评估短路贡献。与传统的同步或异步发电机相比，转换器接口的风力涡轮机（WT）产生显著不同的电流波形特征。本文提出了一种新的相量域建模方法的III型风力发电机与双馈感应发电机（DFIG）使用的概念，基于控制的等效电路。该模型考虑了负序量对WT控制响应的影响，实现了不平衡故障的准确模拟。
The integration of renewables into power systems introduces several technical challenges including the development of appropriate models for system protection studies and accurate evaluation of short circuit contributions. Converter interfaced wind turbines (WTs) produce significantly different current waveform signatures compared to the traditional synchronous or asynchronous generators. This paper proposes a new phasor domain modeling approach for Type III WTs with doubly-fed induction generators (DFIGs) using the concept of control based equivalent circuits. The proposed model accounts for the impact of negative sequence quantities on WT control response to achieve accurate simulation of unbalanced faults.
