摘　　要：针对有些双馈机组受原动机械特性的影响不具备自起动能力问题,以1 MW双馈飞轮储能机组为例,利用双馈电机灵活可控的特点,研究了定子侧与转子侧两种不同的起动方法与并网技术,并比较了各自的特点。仿真验证结果表明,两种方法正确可行,控制简单,为实现无自起动能力的双馈机组高效、经济起动和无冲击并网奠定了理论基础。Due to special mechanical design, some double-fed induction machine （DFIM） units do not have the capa- bility of self start-up. Two methods, i.e. the stator side and rotor side start-up and synchronization, are studied in this paper, which are both simple and no synchronization impact. Simulation is carried out for a typical 1MW DFIM flywheel energy storage system. Simulation results confirm the validity and the feasibility of two methods, which lays the theoreti- cal foundations of DFIM unit start-up effectively and no synchronization impact.
