新型双转子调速风力发电系统的原理设计

Principle Design of a New Type of Double Rotor Speed Regulating Wind Power Generation System

为解决大规模风电并网与电力系统之间的矛盾这一当前风电行业的突出问题,在对比分析常规风电机组技术特点的基础上,提出了一种利用双转子调速装置连接齿轮箱与同步发电机的双转子调速风力发电系统,仿真试验结果表明:该系统可以克服双馈和直驱风力发电机组电能质量不高、可靠性低、维护成本高等缺点,具有较低成本、较高可靠性和较强的电网适应性.

A double rotor speed regulating wind power generation system with double rotor speed regulating device connecting the gearbox and the synchronous generator is proposed on the basis of the analysis of the conventional wind turbine technical characteristics in order to resolve the contradiction between the large-scale wind power grid and the power system. The simulation results show that the system can overcome the shortcomings of double fed and direct drive wind turbines,such as low power quality,low reliability and high maintenance cost,which has low cost,high reliability and strong grid adaptability.
