The Redundancy Technology of Measurement and Control Function of the Smart Substation

Abstract

In order to improve construction economy and system reliability of smart substations, this paper presents an application model of functional redundancy in measurement and control. Puts forward effectiveness identification of data monitor direction in measurement and control functional redundancy, verification of dual monitor, principle of control direction mutex and uniqueness. Makes clear the structure of hardware system, analysis its key technology and realization method. In this method, the central control servers are established in station level. Solves the problems of remote information selection, control authority uniqueness and poor data sharing caused by measure-control devices redundancy configuration according to voltage level in substations. Reduces the numbers of secondary cubicles and interfaces, improves integration of secondary equipment.
