一种通用的继电保护数据库模型

首先分析了公共信息模型在描述保护信息方面的不足，然后以仿真培训系统为实际应用背景，提出了一种通用的继电保护数据库模型，它能够从保护装置的内部结构和外部特征2个方面完整地表达实际的保护装置。该数据库模型允许用户在保护装置级进行保护配置，支持用户通过自定义新型号的保护装置扩展装置模型，支持装置模型升级后保护配置的自动更新，从而大大提高了保护数据库的维护效率。使用该数据库模型实现的各种仿真培训系统现场运行良好、运行维护方便，证明了该模型的有效性。

A General Protection Database Model

Upon analyzing CIM model deficiency in describing protection information,a general protection database model is proposed based on its application in the simulation and training system.The model can reflect reallife protection equipments from internal structure and external characteristics. Based on it,the efficiency of maintaining protection database is greatly improved.The model allows users to configure their protection relays as a whole,to extend by user defining new type of protections,and to automatically update protection configurations after equipments upgrading.Simulation and training systems based on the proposed model are operating well and easy to maintain,which effectively validate the model.
