Flexible power conditioner based on flywheel energy storage

Abstract

According to the situation that the power system can only defense the fault passively, a new FACTS device, which is called flexible power conditioner (FPC), based on flywheel energy storage system is proposed. This device, which employed new technologies such as AC excitation, VSCF and vector control, combines the flywheel energy storage with the traditional phase synchronization technology. FPC can modulate phase, store and generate energy, which can stabilize power system actively. The control strategy and method of FPC is discussed. A 10kVA excitation control system of FPC was developed. Experiment 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.
