ABSTRACT: With the increasing in power demand, complexity work structure and renewable source ration, the smart distribution grid with the self-healing ability has e the certain trend of development. The paper introduces the technical contents and points out the characteristics of the smart distribution grid. Based on the protection and control requirements, the paper proposes the scheme design of the protection and control system for the smart distribution grid. Taking the recent developments munication technology and the exisitng infrastructures in distribution grid into consideration, the paper analyzes some technical issues of protection and control and discusses its implementation in smart distribution grid.
KEY WORD: smart distribution grid; micro-grid; protection and control
