Full-frequency Domain Modeling and Complex Vector Control of Three-phase Grid-connected Inverter
摘要
Abstract
The energy storage battery grid-connected system composed of three-phase grid-connected inverter and its control system can realize bidirectional energy interaction between energy storage device and power grid.Based on the vector control strategy of three-phase system,this paper comprehensively considers the frequency and phase sequence of three-phase AC signals,and studies the influence of coordinate transformation on the system model.Regarding that the conventional frequency domain model established in three-phase static frame doesn't apply to the synchronous rotating frame,the complex vector is introduced,and the full-frequency domain modelling of energy storage battery grid-connected system in synchronous rotating frame is realized by time-frequency transform.On this basis,the complex vector control strategy based on full-frequency domain model is proposed.By improving the symmetry of the full-frequency domain model,the coupling problem of dq axis current signals are solved,and the implementation method doesn't increase the complexity of the control system.Simulation and experimental results show that the proposed complex vector control strategy can effectively improve the dynamic response performance of energy storage battery grid-connected system.关键词
