地铁供电系统继电保护整定研究

Study on Relay Protection Setting of Metro Power Supply System

针对现行城轨供电系统继电保护整定软件存在的不足,开发了一套实用型的地铁供电系统继电保护整定软件,该软件利用数据库来存储和更新系统参数,采用工具箱的可视化图元设计。利用软件编程和数据库技术自定义整定规则,提高了软件的通用性。在整定工作中综合考虑系统运行方式、实际负荷变化、支援供电、电气主接线等因素,使保护性能达到最佳,具有重要的工程应用价值。

In view of the disadvantages of the relay protection setting software for the current urban rail power supply system,a practical visual relay protection setting software for the metro power supply system was developed.The software uses the database to store and update system parameters and adopts the visual graphics primitive design of the toolbox.The relay setting rules is custinuzed by using software program ming and database technology,which improves the versatility of the software.Taking the system operation mode,actual load change,support power supply and main electrical connection into consideration,the protection performance is optimized effectively,which has very important engineering application value.
