面向对象的发电厂继电保护技术管理与培训系统

Object-Oriented Technical Management and Training System of Power Plant Relay Protection

为了能够对继电保护动作过程进行模拟 ,用AutoCAD二次开发形成电力系统继电保护元件库。以此为基础 ,利用AutoCAD的接口文件 (DXF文件 )形成图纸数据库 ,该数据库基于C/S(客户机 /服务器 )架构 ,非常方便地整合入发电厂原有的MIS(综合信息管理系统 )中去并成为其中一个有机组成部分。提出了单个元件的OOP(面向对象 )设计 ,使得继电保护仿真软件具有很高的灵活性和功能易扩充性 。

The power system relay protection element library is developed with AutoCAD to simulate the action procedure of protection relay. Based on it ,the drawing database is formed with the interface file (DXF) of AutoCAD, which is of C/S structure. As a component,it can be easily integrated into the original MIS of power plant. The OOP design for single element is presented, which makes relay protection simulation software more flexible and expandable. The intelligent judgement of network topology is also discussed for the subsequent simulation of relay protection.
