Embodiment

[0043] The power monitoring system of the rail transit power supply system includes the central monitoring system, namely the master station system of the power dispatching center, referred to as the power dispatching center, and its functions mainly include control, data collection and processing, display, alarm, and query. Specific function settings include:

[0044] (1) Remote control function: the system remote control function, that is, the combined and divided remote control of any remote control object connected to the system in the power dispatching center. The remote operation implements strict authority management, and the remote control must be performed by personnel with operation authority or authorization.

[0045] In order to avoid misoperation, at the same time, only one remote control operation is allowed for the same control object system, and all remote control operations must be saved in the system log.

[0046] The remote control is divided into individua...

Abstract

The invention relates to a power monitoring system of a rail transit power supply system. A system composition in an integrated-monitoring-system construction mode is adopted, power monitoring systems and environment and equipment monitoring systems are integrated in a control center and stations, an integrated monitoring system provides an integrated information platform for the different systems, main hardware and software of the systems are uniformly constructed by the integrated monitoring system, and center-level and station-level system functions of the systems are realized by the integrated monitoring system. The power monitoring system comprises a central monitoring system with functions of control, data collection and processing, display, alarming and system authority management. The power monitoring system has functions of control, information collection, data analysis and processing, remote maintenance, statement counting, accident alarming, image retrieval, historical data inquiry of all kinds of equipment, supervises and monitors the equipment in real time, and guarantees normal operation of rail transit.

Description

technical field [0001] The invention relates to a power monitoring system of a rail transit power supply system, belonging to the technical field of power monitoring. Background technique [0002] The rail transit power supply system is the source of power for urban rail transit operations. It is responsible for the supply and transmission of electric energy, power supply for electric train traction and provide power and lighting power for stations, sections, depots, control centers and other buildings. The power supply system should be safe and reliable to ensure power supply. [0003] The power monitoring system is also called the power SCADA system or the telecontrol system, often referred to as the SCADA system, and sometimes also called the PSCADA system. It is suitable for high-voltage 66-110KV equipment, medium-voltage 10-35KV equipment, DC 750V or DC 1500V equipment, and low-voltage 400V equipment in different types of substations such as urban rail power supply sys...
