Design And Application Of Urban Rail Transit PSCADA

The urban rail transit power monitoring system, called as PSCADA or power far move system, has been developed based on the demand of monitoring and controlling the power distribution equipments. PSCADA can supervise many types of electric equipments for different power supply substations, such as high-pressure equipments, low-pressure equipments, direct-power supply equipment, alternating current screen, discharging current cabinet, etc. It can also accomplish other functions like the realization of power control, collecting various information, data analysis processing, the far-away system maintaining, the breakdown report, history data searching, etc. Therefore, PSCADA is significant meaningful for ensuring the city track power system running successfully and safely.The thesis does some deep researches on power monitoring system of Nanjing rail transit based on a lot of academic papers on this field, combing the actual engineering situation of Nanjing Metro Line10, and have finished the demand analyses of supervision system is persented furrhermore. an integrate scheme has been designed, which includes the power supervision’s hardware design and software design, equipment configure and computer programming, etc. Finally, an urban rail transit power monitoring system is completed. It has been tested for a period of time since this system was put into operation, the equipment runs steadily, and the functions are carried out successfully and effectively, which includes testing state information, recording events, locally displaying, long-distance data transporting, monitoring operation and automatically trouble reporting. All the indicators meet the design requirements.
