Study On New-Style Automation Supervisory And Control System Of Distribution Station

The electric distribution station automation technology develops rapidly recent years, but the technology lays stress upon 11OkV and 35kV level distribution station. 1OkV distribution stations are often located at electric distribution terminals and the domain of accident influence is little, so 1 OkV distribution stations automation technology develops slowly. In addition, because the geographic environment of the station is complicate, a low voltage distribution station automation supervisory and control system is necessary for power supply & consume departments. A few stations are combined into a supervisory and control group by handy communication way, The system realizes remote signalling, remote measuring and remote controlling. As a control unit of the upper supervisory and control system, it improves safety and reliability of city low voltage electric fence effectively.This paper presents a new structure orient to unattended low voltage level distribution station automation, and designs corresponding configuring supervisory and control software system. The supervisory and control software system not only control the working state of distribution station electric device, but also has the function of remote maintenance and configuration to the electric distribution station supervise computer of the new structure distribution station automation.The distribution station supervisory and control software system adopts the solution scheme based on the Internet technology, therefore the software system becomes more modularized and open. Viewing remote operating condition of distribution station automation system at any moment can not only save client soft hardware cost and but also avoid the maintenance of client and the repeat invest in development software. The electric distribution station configuring supervisory and control software system extends to Internet through ActiveX component and DCOM data access technology, hence the software system is more open and easier to maintenance. The paper do some new exploring in the correlative domain.
