摘要
为了研究风力发电系统控制、功率输出估计及动态特性需同时考虑风速和风向的随机特征,建立考虑风向影响的风速模型。根据Box-Jenkins的建模思想,以样本相关分析为出发点,并借助于样本典型相关分析的有关概念及分析方法,建立了考虑风向影响的合成风速模型。在Matlab/Simulink仿真平台上对风速模型进行了仿真;实现了与电力系统分析程序DIgSILENT/PowerFactory的接口;通过仿真验证所建模型的合理性。
The stochastic properties of wind speed and direction affect simultaneously the output power and dynamic characteristic of wind power generation system. The description of stochastic properties of wind speed and direction is essential to study the control, output power and dynamic characteristic of wind power generation system. So the stochastic model of wind speed time series affected by wind direction was set up based on sample analysis of correlation and Box-Jenkins modeling. Matlab/Simulink and intergrated The stochastic model of wind speed affected to DIgSILENT//PowerFactory. The rationality by wind direction were presented in of model was verified by simulation.
