Abstract
Inverters used in microgrid system need to be run in grid-connected and islanding modes, which need to extract the phase of the grid and establish the internal phase of the system respectively. At present, conventional PLL can only be used in a certain mode and is invalid during mode switching. Therefore, a new type of PLL used in microgrid system is present in this paper base on resonant theory. With this method, the phase can be transited smoothly and current distortion can be reduced during mode switching. Finally, a 50kW microgrid experimental platform is designed base on F28335. Experimental results demonstrate the feasibility of the model and the correctness of the theoretical analysis.关键词
