发电厂继电保护综合分析管理系统的研究

介绍了一种基于面向对象设计的发电厂继电保护综合分析管理系统。该系统将继电保护整定计算、潮流计算、故障计算、动作仿真集成于统一的图形数据一体化分析平台。图形平台以发电厂电气主接线为背景,提出了基于捕捉点的全网拓扑形成的三层模型,实现了电气接线图绘制、运行方式设置、参数查询、计算结果显示等功能。故障计算结果可转化为Com trade格式的录波文件,通过继电保护测试仪与继电保护实际装置接口,为保护装置测试提供了一个面向实际电网运行方式的分析环境。该系统已在珠海发电厂投入运行,效果良好。

Management information system for the comprehensive analysis of power plant relay protection

An object-oriented design based management information system for the comprehensive analysis of power plant relay protection is introduced,and the computation of relay setting,load flow and fault process, and the simulation of relay action sequence are implemented in a graphic-model integrated platform.The graphic platform is based on the electrical configuration diagram of power plant,a novel three-layer model for topology analysis is proposed,and the diagram drawing,the operation mode setting of power plant,the display of results can be easily implemented.The results of fault analysis can be output to the relay testing device based on Comtrade Standards,so the relay testing can be performed under the real operation mode of large scale power system.The system have been run in Zhuhai Power Plant,and the results are satisfactory.
