In order to improve the flexibility and economy of research on wind power, a wind power simulation platform is developed.The upper computer software simulates the wind turbine system by respectively building the models of wind speed, wind blade and the transmission system.The hardware of the platform is implemented by designing the grid-connec-tion device and programming the control method of the motor and.In order to keep a high power factor at different wind speeds,a strategy for capacitors cutting-in or cutting-off in group is brought forward.The platform is proved that it can cor-reedy simulate the condition of the actual wind turbine as the power curve given by experiments which is roughly the same as the one given by Bladed.%为了提高风力发电研究的灵活性和经济性,对风力发电模拟甲台进行了研究、设计和实现.分别对风速、风机和传动系统进行了建模.得出相应的数学模型.并用上位机软件进行模拟.通过对伺服屯机的控制和并网装置的设计.搭建了风力发电模拟平台.针对风力发电机组输出功率不稳定,容易造成无功补偿不足或过补偿等问题,提出并制定了补偿电容自动分组投切策略,使风力发电机组在不同风速下运行时,功率因数始终接近1.利用风力机模拟软件Bladed进行了仿真.实验结果证明该模拟平台可以准确地模拟实际风力发电机组的工况.
