摘　　要：针对目前电力系统故障时只能被动防御的局面,提出了一种新型FACTS装置,即储能调相功率调制系统,它将飞轮储能技术和传统的同步调相技术有机地结合起来,同时采用交流励磁、变速恒频和矢量控制等先进控制技术,使之具有储能、发电和调相等多种功能,将其用于电力系统的稳定性控制,使主动致稳成为可能。文中详细论述了该FACTS装置的核心部件——柔性功率调节器的控制策略和实现方法,并对系统实现所遇到的几个关键问题进行了深入分析。初步的研究结果表明,该装置可实现有功功率和无功功率同时四象限大范围的快速调节,使电力系统的稳定性增强成为可能。According to the situation that the power system can only defence the fault passively, the paper offer an new FACTS device named energy storage power modulation system（ESPMS）. This device, which employed new technologies such as AC excitation, VSCF and vector control, combines the flywheel power storage with the traditional phase synchronization technology. ESPMS can modulate phase, store and generate energy, which can stabilize power system actively. This paper also shows detailed discussion about the control strategy and method of flexible power conditioner（FPC） which is the core equipment of ESPMS and analysis referring to several key problems about system realization. Initial results reflect that this device can quickly and enormously modulate the active power and reactive power in four-quadrant, which makes power system stability possible.
