摘　　要：针对水平轴串列式双风轮风电机组多输入多输出(MIMO)复杂非线性气动特性,提出了一种前后风轮干涉条件下的双风轮风电机组气动MIMO系统全工况分段仿射自回归(PWARX)建模方案。结合所搭建的双风轮风电机组半物理仿真平台进行运行仿真和测试验证,分析了该模型在不同工况场景下的输出值对实际值的跟踪精确度。结果表明:所建立的双风轮风电机组气动MIMO系统的PWARX模型对双风轮风电机组全工况气动特性具有高精度的全局逼近能力。Aiming at the complex nonlinear aerodynamic characteristics of multiple-input multiple-output(MIMO),a piecewise affine regressive exogenous(PWARX)modeling scheme for dual wind turbine under the condition of front and rear wind turbine interference was proposed.Combined with the semi-physical simulation platform of dual wind turbine,the simulation and test verification are carried out,and the tracking accuracy of the output value to the actual value under different working conditions was analyzed.Results show that the PWARX model of the dual wind turbine MIMO system has a high precision global approximation ability to the aerodynamic characteristics under all operating conditions.
