摘要
介绍了变速恒频风力发电机的基本运行机理及其PSASP/UPI仿真模型的开发原理。采用统计学方法分析了风电场中风电机组的实测运行数据,并在此基础上重新建立了适用于联网风电机组仿真模型的风速–功率特性曲线。仿真结果表明,该曲线更接近于风电机组的实际运行情况,在变速恒频风力发电机的仿真模型中,采用上述曲线能显著提高仿真的精确性。
The basic operation mechanism of variable speed constant frequency （VSCF） wind power generator and the development principle of PSASP/UPI simulation model applied to VSCF wind power generator are presented. By / means of statistical method the measured operational data of wind power generation unit in wind farm is analyzed, on this basis the wind speed vs output power characteristic curve suitable to the simulation model of interconnected wind power generation unit is rebuilt. Simulation results show that the rebuilt curve is more close to actual operation mode of wind power generation unit. Applying the rebuilt curve to the simulation model of VSCF wind power generator, the accuracy of simulation can be evidently improved.
