基于EMTP/ATP的双馈式风力发电系统的模型与实现

摘要

以电力系统电磁暂态分析软件EMTP/ATP为平台,采用电机矢量控制技术以及比例一积分调节器串联校正等方法建立了双馈风力发电系统的电磁暂态仿真模型,该模型包括风速模型、风力机模型、双馈发电机模型,以及有功、无功解耦控制系统的模型.依据变速风电机组的运行特性对该模型进行了仿真研究,仿真结果验证了该模型的有效性.%Based on the vector control theory and proportional integral regulator series correction method, an electro-magnetic transient model of wind power system with doubly fed induction generator (D.FIG) is established using EMTP/ATP software.The model comprises a wind speed model, a wind turbine model, a doubly fed induction machine with its control system, and a decoupling control system model for active power and reactive power. System simulations are carried out and the result shows the effectiveness of the proposed model.
