摘要
以液压传动型风力发电系统为研究对象,针对液压调速回路元件选用的实际情况,建立了定量泵-双变量马达调速系统、永磁同步发电机及风轮的数学模型。采用AMESim软件建立液压调速系统仿真模型,采用MATLAB/Simulink软件建立永磁同步发电机及风轮仿真模型。应用模糊控制方法,分析了液压传动变速恒频风力发电系统马达的转速特性。研究表明,定量泵-双变量马达液压调速系统能实现永磁同步发电机转速稳定控制。
With wind power generators of hydraulic transmission type as the research object, the mathematical model of the fixed displacement pump-double variable displacement motors speed regulating system, the permanent magnet synchronous generator and wind turbine were established aiming at the actual situation of hydraulic component in speed regulation circuit. The mathematical model of fixed displacement pump-double variable displacement motors speed regulating system was established through the AMESim. The mathematical model of permanent magnet synchronous generator and wind turbine were established through the MATLAB/Simulink. Using the method of fuzzy control, the VSCF generator speed characteristics was theoretically analysed. Research shows that the fixed displacement pump-double variable displacement motors speed regulating system can make the permanent magnet synchronous generator speed stability.
