能量管理系统和继电保护信息系统集成平台研究

介绍在广州供电局实施的能量管理系统（EMS）与继电保护信息系统统一数据平台方案，以便基于此平台实现继电保护信息系统免维护。该平台实现了数据模型规范化，采用了双服务器、双网冗余结构，保护所有信息在调度集控一体化平台上整合，形成完整保护的信息库。在硬件上，该平台的故障信息系统工作站采用双工作站并行模式和嵌入式结构。文中还分析了该方案实施后所发现的问题，指出二次设备的建模和管理是完善该方案的关键。

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. energy management system (EMS); relay protection; relay fault information system; integration platform
