Design And Application Of Regional Substation DC Power Remote Monitoring System

DC power system plays a very important role in power system，it usually refersto by the storage battery, inverter and other auxiliary circuit of power supply system.In the area of DC power, they asked for DC power can run stability, the higherrequirement is convenient in the work, and it can carry on the remote monitoring. Thisarticle is based on the Wuhai area substation dc power monitoring system status, studydeeply and analysis the key technology of dc power supply remote monitoringsystem， modify the original DC power battery system to realize the remotemonitoring，improve the automation level of transformer substation DC power system,complete its function, enhance the security and stability of this system.In power system, DC power system is an important component of the substation,it also related to the operation and control of the electrical equipment. Due to thevarious of DC system equipment, distribution of scattered, it is needed to maintenanceand monitoring usually. This paper puts forward a kind of intelligent DC powerremote online monitoring technology, it can collect battery real-time data from allwork module and back to the control center. The scheme can not only reduce theworkload of the maintenance personnel, at the same time it can monitor the dcequipment real-time, it can master the working state of the battery at any time,improve the whole operational substation level.In this article, we design the system monitoring terminal software and sub stationmonitoring communication module, we can monitor and browse all the data frommonitoring terminal, observe DC equipment running status from DC systemsimulation diagram, and can remote control state of busbar voltage switch, observethe battery temperature and battery charging and discharging, the battery voltage andcurrent can form in tabular form data graph, view the history data and contrast,through monitoring software changes the module parameters, etc.
