Abstract  

A novel wind turbine with hydro-mechanical hybrid transmission was proposed to solve the problems in traditional wind turbines, such as high failure rate in gearboxes, technological sophisticated inverters, harmonic interference. The variable speed constant frequency (VSCF) control algorithm was presented through the theoretical analysis on the transmission characteristics of the system and the establishment of a dynamic model of the wind turbine. A cosimulation of AMESim and MATLAB/simulink was conducted on a 1.5 MW grid wind turbine. The simulation results validated the feasibility of the transmission system. The novel wind power generation system is characterized by simple VSCF control algorithm, low load impact, power stability, high transmission efficiency and grid-friendliness.

风电机组的机械液压混合传动技术

针对传统风电机组具有齿轮箱故障率高、变流器技术复杂及谐波干扰等问题,提出基于机械液压混合传动的风力发电机组.通过理论分析系统的传动特性,建立该风力发电机组的动态模型,给出基于该传动方式的变速恒频(VSCF)控制方法.以1.5 MW并网风电机组为例,利用AMESim 与MATLAB/simulink软件对机组运行工况进行联合仿真分析.仿真结果验证了理论分析的正确性,表明提出的机械液压混合传动式风力发电系统具有变速恒频控制方法简单、载荷冲击小、功率稳定性好、传动效率较高、电网友好性好等特点.
