The Construction Of Safety Control Platform For Linan Grid

Lin an is located in the western suburbs of Hangzhou, the capital of Zhejiang Province. As of the end of 2015, under the jurisdiction of Lin an, there are 55 overhead transmission lines with 35 kV - 110 kV voltage class, and the total length of 705.651 km, of which 25 35 kV lines with a length of 290.177 km, 30 110 kV lines with a line length is 415.474 kilometers. As the backbone of the local power grid network frame, transmission lines are not only the artery of the city's power grid, but also connect the surrounding grid system. Therefore, the safety and stable operation of 35 kV - 110 kV transmission network is closely related to the broad masses of the people.In recent years, with the continuous development of power grid, power line distributes to wider and wider regions.As a matter of fact, the line tripping fault happens from time to tome. For this reason, it is urgent to analyse the cause of grid breakdown of Linan, identify the shortcomings and the insufficiency of transmission line safety protection measures, and raise accident preventions according to the current condition of Linan power grid transmission lines. And the grid equipment safety precontrol information platform is a management information system, which contains digital geographic information, grid structure, power grid and account of potential safety hazard graphic video, equipment safety operation procedures. Its outstanding characteristic is with the combination of digital geographic information system, to describe the structure information of power grid and the running status of safety potential hazards, to assist with efficient and scientific management and decision-making, to reduce operating costs, and to ensure the power supply reliability.Hope this article can give some reference to the colleagues engaged in the work of the grid security control and related technical personnel.
