Micro-grid System in Auxiliary Power System of Substation

Abstract

This paper analyzes and summarizes the operation of conventional power and proposed the station of micro-grid. Firstly, the paper introduces the structure of each part of the station with a micro-grid system and describes the role and function of each part of the power system. Then, the paper states the influence which the station of micro-grid affects to a network of distribution and summed up its own role. In the end, the paper discusses the research orientation on the station of micro-grid and the advantage of the station with micro-grid. Experiments show that when the traditional grid is in normal operation, the micro-grid connects the operation station and the substation system, and will disconnect from the grid when the power quality is not met. This paper implements intelligent and flexible control on the micro-electronic website and has formed a “plug and play” function on the micro-electronic website. This paper can also realize unattended substation, troubleshooting, automatic mode conversion and so on.
