摘　　要：差动调速型风电系统,可在无需电力电子变频设备时与电网友好连接,有望解决现役主流变速恒频并网风力机无功功耗大、低电压穿越能力弱、输出电能质量和动态稳定性不高等问题。为了进一步提升该型风电系统的运行性能,消除高成本传感、控制单元及大功率伺服电动机带来的不利影响,提出一种新颖的具备自稳速功能的差动调速型风电系统传动方案。以自稳速风力机为研究对象,在确定其传动系统配置形式的基础上,推导所提机组的传动原理,并对其传动特性展开深入研究。搭建自稳速型风电机组半物理试验平台,利用岭回归算法计算得到试验台关键惯量和阻尼参数。最终在变化风速下,开展仿真和试验研究,验证所提风电机组的可行性和优越性。Wind power generation system,equipped with the speed regulating differential mechanism(SRDM),is able to be friendly connected to the power grid without the need for partially-or fully-rated converters.The novel alternative transmission schemes have shown promising potential in addressing several issues present in existing variable speed constant frequency grid-connected wind turbines(WTs),such as huge reactive power consumption,weak low voltage ride through ability as well as unsatisfactory output power quality and dynamic stability.To further improve the operational performance of SDRM-based WT and eliminate the adverse effects caused by the high-cost sensors,high-power speed regulating motor and corresponding expensive control units,a novel WT transmission scheme equipped with a self-stabilizing SRDM is proposed.Taking the self-stabilizing SRDM-based WT as the research object,its kinematic principles and transmission characteristics are thoroughly studied,on the basis of determining the structural configuration of the proposed transmission system.A dedicated semi-physical experimental platform is constructed,and its key inertia and damping parameters are calculated by using the ridge regression algorithm.Finally,simulation and experimental case studies are conducted under varying wind speeds,through which the feasibility and superiority of the proposed self-stabilizing SRDM-based WT are verified.
