摘　　要：基于RSCAD/CBuilder采用自定义编程技术开发一套双馈式感应风力发电机(DFIG)的通用励磁控制模型。该模型控制策略依据网侧变换器电网电压定向、转子侧变换器定子磁链定向矢量控制原理;模型的人机交互界面根据面向对象设计理念,形成参数输入对话框;模型的实时运行程序采用C语言编程技术,并针对信号相位提取、相位斜率计算给出相应的设计方法。本文还以实例对比法对所开发模型进行了通用性和精确性验证,结果表明:该模型可便捷地应用于不同系统频率、功率等级DFIG的RTDS仿真实验并大幅提高建模效率。In this paper,a set of general excitation control model for doubly-fed induction generator（DFIG）is developed based on RSCAD/CBuilder by using custom programming technology.The model control strategy is determined according to the grid voltage orientation of converter at grid side and the stator flux orientation of converter at rotor side.Based on object-oriented design concept,parameter input dialog box is built on man-machine interactive interface of model.The real-time operation program is compiled with C language and can provide design method for extraction of signal phase and calculation of phase slope.In the end,the versatility and accuracy of the developed model are verified with an example.Results show that the model can be applied to RTDS simulation experiment with various types of DFIG conveniently and can improve modeling efficiency greatly.
