摘要
Abstract
The coefficients of the droop controller influence the transient response and the stability of the wireless paralleled inverter system. Traditional design of the droop controller is usually accompanied by the small signal model based on the quasi-stationary phasor. However, the quasi-stationary phasor representation of sinusoidal signals is limited in analyzing the faster response of paralleled inverter system. This paper focuses on the parallel operation of 400 Hz inverters which employ the droop controller. A small signal model which based on the time-varying phasor of this system is built. The theoretical analyses show that the traditional small signal model is limited in designing the parameters of the paralleled inverter system. Compared with the traditional small signal model, the small signal model based on the time-varying phasor can reflect the transient processes of the droop regulating. Therefore, the parameters of the paralleled system can be designed more accurate with the small signal model in this paper. The validity of the proposed model is proved by the simulation and experimental results.关键词
