Research of an Integration Platform for EMS & Relay Fault Information System

An integration platform scheme of energy management system (EMS) relay fault information system implemented in Guangzhou Power Supply Bureau is introduced. Based on the platform it is possible to realize maintenance-free of the relay information system. The platform has characteristics of standardized data model, dual-server and dual-redundant network structure and integration of all the relay protection information on the central-control dispatching platform. Thus the plaform is an integrity information database. In terms of hardware, dual-mode parallel workstation and embedded structures are employed by the relay fault information system of the plaform. In addition, analysis on the existing problems of the scheme in practice points out that the modeling and management of the secondary device are the key issues to improve the scheme.
