摘要

针对大型化、高可靠性、长寿命的高端风电装备发展趋势，研究风电装备动力学特性，基于风电装备能量流、物质流、信息流与各部件拓扑关系，确定风机整体式动力学建模流程；综合考虑叶轮捕获风能、风载及传动系统模型与电网发电作用载荷模型，借助SIMULINK软件对风电装备整体动力学模型仿真分析。结果表明，风电装备转速、功率特性与风机额定工况运行参数基本相符，从而验证整体式动力学模型的可信度；风电装备扭矩从叶轮端传递到发电机端，扭矩波动幅值降低，且兆瓦级风机叶轮端扭矩量级为E6 Nm，发电机端扭矩量级为E4 Nm；可对增速箱输入、输出端扭矩曲线进行包络线拟合，为增速箱内部功率损耗分析提供宏观边界条件。

Abstract

Large-scale, high-reliability and long-life have become the development trends of wind power equipment. Therefore, the research on dynamic characteristics has great significance in improving design and manufacturing technology of wind turbine. Integral dynamic modeling process is established based on energy flow, material flow, information flow and topological relationship of wind turbine. Furthermore, integral dynamic model is simulated by using SIMULINK, considering wind energy model, wind load model, transmission system model and grid load model. As a result, rotate speed characteristic and power characteristic are similar to operating parameters under the rated condition, which verifies the reliability of this simulation. Moreover, the torque fluctuating amplitude is decreasing from impeller to generator and the torque magnitude of impeller is , while that of generator is . In addition, the torque envelope line of gearbox will be fitted to provide macro boundary condition for gearbox power loss analysis.
