摘　　要：飞轮储能系统将能量储存在高速旋转的飞轮转子中,具有高功率密度、无环境污染、使用寿命长、运行温度范围广、充放电次数无限制等优点,已获得了广泛的应用。将多台模块化的飞轮储能单元并联起来组成飞轮阵列储能系统,是获得大容量、高功率储能的解决方案。文章首先论述了飞轮阵列储能系统的国内外发展现状与要解决的关键问题,然后详细给出了飞轮阵列储能系统的设计方法、并联拓扑结构与控制策略。随着飞轮储能单元并联技术的逐渐成熟,飞轮阵列储能系统应用领域将逐步扩展到电力系统调频、间歇式可再生能源发电等领域,并将在提高电网对可再生能源的接纳能力等方面发挥重要作用。Flywheel energy storage systems （FESS） store energy in a rotating mass. The advantages of such systems includes high power density, environmental friendliness, long lifespan, wide operating temperature range, and very long charge-discharge cycle life. FESS has therefore been widely used in numerous applications. Integrating multiple flywheel energy storage units to form a flywheel array energy storage system （FAESS） provides a mean for large scale energy storage. In this paper, an overview of the current development status and key technologies of FAESS is given. Design method, parallel topology and control strategy of FAESS are then presented. With enhanced control technologies for parallel operation of flywheel energy storage units, FAESS could be used for grid frequency regulation particularly for dealing with intermittent renewable energy generation.
