摘要

针对现代大型风力发电机组在额定风速以下的输出功率波动问题,提出一种利用风轮大转动惯量实现无储能系统的功率平抑策略。首先利用风电机组本身特性给出具有即时性的精确等效风速参与控制;通过基于高气动效率区宽速比的叶片设计对每段风速设置转速上下限,同时给出整个惯量控制过程,实现风轮的能量储存和释放;通过大数据构建多个基于风速脉动趋势斜率的预判模型,实现转矩预判动作。最后,在专业仿真软件Bladed和实际某风场中进行功率输出对比仿真和实验。其结果表明,所采用的策略在不外加储能设备的情况下,有效平稳了风力发电机组的输出功率。

Abstract

A power smoothing strategy without energy storage system by utilizing the large rotational inertia of the wind turbine rotor to achieve power smoothing is proposed to solve the problem of output power fluctuations of modern large-scale wind turbines under rated wind speed. Firstly, the inherent characteristics of the wind turbines are employed to provide an immediate and accurate equivalent wind speed for control participation. Secondly, the upper and lower limits of the rotational speed are set for each wind speed segment based on high aerodynamic efficiency zone and wide speed-ratio design, and the entire inertia control process is given simultaneously to achieve the energy storage and release of the wind turbine rotor. Subsequently, multiple prediction models based on the slope of the wind speed pulsation trend are constructed via big data sources to realize the predictive action of the torque. Finally, the comparative simulation experiments of the power output of the wind turbine are carried out by BLADED simulation software and a certain actual wind farm. The results show that the adopted strategy stabilizes the output power effectively without the additional energy storage devices.
