许多电网规范中对基于测量的仿真模型验证的新要求表明，双馈发电机系统（DFG）的发电机和变流器模型的现有通用方法可能不够准确。作者表明，通过对发电机方程和转换器控制设计进行详细分析，可以在保持高精度的同时降低模型复杂性。本文中提出的发电机模型允许改进的代表性的静态和动态响应的风力涡轮机配备DFG系统，特别是在电网故障和电压恢复期间。该模型的目的是代表现代DFG系统独立的供应商特定的硬件和软件。模拟的结果进行比较，涉及风力涡轮机的电压骤降的测量。该发电机模型已被提议作为WECC/IEEE发电机模型的扩展，并已被IEC TC 88工作组27（标准IEC 61400-27-1）接受为风力涡轮机建模和模型验证的参考。
New requirements for the validation of simulation models based on measurements in many grid codes show that existing generic approaches for generator and converter models of doubly fed generator systems (DFG) may not be accurate enough. The authors show that by applying a detailed analysis of the generator equations and the converter control design, a reduction of the model complexity is possible while maintaining a high level of accuracy. The generator model presented in this paper allows an improved representation of the stationary and dynamic response of wind turbines equipped with DFG systems especially during grid faults and during voltage recovery. The model is designed to represent modern DFG systems independently of vendor specific hardware and software. The results of simulations are compared to measurements of a voltage dip involving wind turbines. The generator model has been proposed as extension to the WECC/IEEE generator models and has been accepted as reference for IEC TC88 working group 27 (standard IEC 61400-27-1) on modeling and model validation of wind turbines.
