Remote operation and maintenance technology of substation supervisory control system based on GPS

In order to adapt to the unattended substation mode and improve the operation and maintenance efficiency of substation supervisory control system, the ICT(Information and Communication Technology) is adopted to carry out the research and application of remote operation and maintenance technology of substation automation. The architecture of remote operation and maintenance system of substation based on general service protocol in electric power system is designed, the framework of information interaction between main station and substation is established. According to the security requirements of the secondary system of electric power system, the architecture of whole process safety management system, which includes communication layer, protocol layer and application layer, is designed, and the whole process safety management flowchart of service life cycle oriented is proposed. To meet the requirements of remote operation and maintenance of substation supervisory control system, five kinds of application functions of remote operation and maintenance are extracted. According to the technical scheme of remote operation and maintenance, a complete test environment is built, which is used to carry out the remote operation and maintenance interoperability test. The test results prove the feasibility of the technical scheme. The pilot application of technical scheme has been carried out in Nanjing and Suzhou of Jiangsu Power Grid.
