The Design and Research of Three-Phase Inverter Dual-Loop Control

Abstract:

A dual-loop (inner current loop and outer voltage loop) control scheme for micro electric source inverters in microgrid is improved in this paper. In order to make dual-loop control analysis more accurate, LC filter, SVPWM module equivalent are included in the inverter supplied system model. Based on the fully decoupled dq axis model,the PI controller are used in both inner current loop and outer voltage loop. The inner current loop is designed with engineering algorithm and the outer voltage loop with bode diagram and step response. The simulation results show the validity of the designed control in that the proposed design methodology not only enhances steady state performance of the system, improves the voltage quality but also enables the current limiting.
