摘　　要：风热机组是风能热利用的主要形式之一,压缩机特性和控制策略的改变会造成其载荷有别于风电机组,为了探究两者载荷特性的异同,本文以2 MW风电机组为基本模型,在GH Bladed中通过修改模型中电机参数和控制策略,得到实际运行的风热机组的模型。通过与风电机组对比,得出风热机组在叶片y方向、轮毂和塔架y以及z方向的力矩都有所减小的结论,为风热机组叶片等部件的强度校核提供了参考。Wind heating units are one of the main forms of wind energy heat utilization. Changes in compressor characteristics and control strategies can cause their loads to be different from those of wind turbines. In order to explore the similarities and differences in load characteristics between the two, this article takes a 2 MW wind turbine as the basic model and modifies the motor parameters and control strategies in the model in GH Bladed to obtain the actual operating model of the wind heating unit. By comparing with wind turbines, it is concluded that the torque of wind turbines in the y direction of the blades, the y direction of the hub and tower, and the z direction has decreased,providing a reference for the strength verification of wind turbine blades and other components.
