在不具备风场环境的情况下,针对液压型风力发电机组风力机特性模拟问题,在实际数据的基础上,建立了风力机输出特性数学模型,依据相似模拟的原理,采用转速控制的补偿方法对风力机特性进行了实验研究。将等效功率实验数据乘以转换系数之后的结果、仿真结果以及相关合作公司提供的850 kW风力机的实际数据进行了对比。结果表明:系统能够在误差允许范围内精准模拟风力机的输出功率和输出转矩。
Aimed at the simulation problems of the wind turbine characteristics in hydraulic wind turbine without wind field environment,a mathematical model of the wind turbine output characteris-tics was established on the basis of the actual data.According to the similar simulation principles and the use of direct speed control compensation method,the experiments of wind turbine characteristics were conducted.Finally,the results of the equivalent power experimental data multiplied by the con-version coefficient,the simulation results and the actual data of 850 kW wind turbine provided by the related cooperation company were compared,and the results show that the system can accurately sim-ulate the output power and output torque of wind turbine in the range of allowable errors.
