摘　　要：针对新能源场站惯量、无功功率不平衡、有功及频率支撑能力不足的问题,提出了一种将飞轮储能技术与双馈电机技术结合起来的储能型复合调相机,该调相机结合锂电池储能,提升了系统的调频速度与容量。与同步调相机相比,可以利用滑差进行大转速范围的调功,在相同的惯量下,储能型复合调相机调功时间更长,更有利于增强电力系统的稳定性。对储能型复合调相机进行了仿真分析,结果表明,其具有良好的功率调节特性,应用于电力系统中,既可实现发电、储能、调相等功能,又可实现有功功率和无功功率双向大范围迅速调节。Aiming at the problems of inertia imbalance,reactive power imbalance,and insufficient support capacity of active power and frequency of new energy stations,an energy storage composite condenser combining flywheel energy storage technology and doubly-fed motor technology was proposed.The condenser combined with lithium battery energy storage,to improve the frequency modulation speed and capacity of the system.Compared with the synchronous condenser,the power adjustment can be carried out in a large speed range by using slip.Under the same inertia,the power adjustment time of the energy storage composite condenser is longer,which is more conducive to enhance the stability of the power system.The simulation results show that it has good power regulation characteristics.When applied in power system,it can realize power generation,energy storage,phase modulation and other functions at the same time.It can also realize bidirectional and rapid adjustment of active power and reactive power at the same time.
