Laboratory Test of Dynamic Operation Characteristics of Flexible Power Conditioner

柔性功率调节器(FPC)是一种集成了飞轮储能技术和双馈电机技术两者优点的新型FACTS装置,具有电能存储、有功功率和无功功率解耦调控等多种功能。本文介绍了所研制的380V/4kW FPC样机的构成,对该样机进行了全面的运行特性实验研究,对实验数据进行了分析,结果表明,FPC样机可以直接变频启动,在亚同步状态和超同步状态下均可以进行有功功率和无功功率的双向独立调控,具有良好的动态运行特性,从而验证了FPC技术的可行性。

Flexible power conditioner（FPC） is a novel FACTS device which integrats both the characteristics of flywheel energy storage and the doubly-fed induction generator.It can perform multi-functions including energy storage,dynamic active and reactive power conditioning.A 380V/4kW FPC prototype is developed and detailed laboratory test of the dynamic operation characteristics of the prototype is performed in this paper.The test results show that the prototype can perform frequency conversion start without supplementary starting equipment,and exchange the active power and reactive power with the grid independently and quickly at both the sub-synchronous and super-synchronous operation states.The feasibility of the FPC is validated.Satisfactory characteristics dynamic operations are obtained.
