摘要
基于统计风速模型和ARMA模型产生的模拟风速实现实验室的风速模拟,利用风电场采集的实际数据进行频谱校正,使之最大限度接近风电场真实风况。通过对风力机的风轮、传动轴、齿轮箱、变桨距系统及气动转矩的脉冲特性进行建模,实现从风的产生到传动链各环节的模拟,模拟过程在DSP中实现,由DSP给变频器发送转矩指令,变频器采用直接转矩控制调节异步电动机的电磁转矩。实验结果证明了该方法的可行性。
A new simulation algorithm combining statistic wind model and ARMA model was put forward to produce simulation wind. With practical data collected in the wind farm, the simulation wind speed was corrected in spectrum mimicry to approach the real wind speed in actual wind farm with maximum limit. The rotor, drive axis, gear- box, variable pitch system and pulse performance of aerodynamic torque of wind turbine were modeled to simulate the wind and total drive train. The simulation process was realized in DSP and the torque commands were sent to converter by DSP to regulate the torque of asynchronous motor with direct torque control strategy. The feasibility of simulation method was verified with real experiments.
