Dynamic Modeling and Simulation on Directly Driven Wind Turbine with Permanent Magnet Synchronous Generator with Power System

随着风电技术的不断发展,风电并网显得尤为重要和迫切,而动态模型是研究风电并网特性的重要工具。本文从风力发电系统总体结构出发,分析了发电系统的控制策略,建立了直驱型风力发电系统的动态模型。并对所建立的模型进行了仿真分析研究,结果表明所建立的模型能满足系统要求,为进一步研究并网风电机组的低电压穿越特性和电能质量奠定了基础。

With the development of wind power, the wind power connected grid is especially important and urgent, and the dynamic model is the important tools to study characteristics of wind power with grid. This paper, from the overall structure of wind power system, analyzes the control strategy of power generation system, establishes a dynamic model with PMSG wind power system. And after analysis the model, the results show that the model can meet the system requirements, and have a foundation for further study on the low voltage ride-through ability and power quality.
