Abstract：The flexible power conditioner(FPC)is a novel FACTS device which integrating both the characteristics of flywheel energy storage and the doubly-fed induction generator. And the electromechanical wave propagation is a new idea for analyzing and studying active power oscillations. In this paper, the electromechanical wave propagation is applied to improving power system stability. The characteristic of the electromechanical wave propagation on the system with single generator is analyzed as well. The stability control method of the FPC based on the electromechanical wave propagation is proposed. A 380V/4kW FPC prototype was developed and the corresponding controller was designed as the proposed method. The test results of the prototype show that the FPC can effectively improve the system stability. The feasibility of the proposed method and the practicability of the FPC are validated.
