Abstract:The purpose of this paper is to analyze the process layer GOOSE, SV adopts the "network acquisition network trip" structure, and the intelligent substation that carries out data transmission on the same network. The reasons why the protection and measurement devices can not receive the position data of the switching devices on the intelligent terminals and other abnormal phenomena have emerged. The reason is that two solutions are put forward, and the cost performance ratio is compared and analyzed. A special network system for protection measurement and control device debugging and calibration of GOOSE and SV common network is designed.By temporarily adjusting the network of the interval process layer of the equipment under inspection into a dedicated network system during the calibration, verification and overhaul work of the protective monitoring and control device, To solve the problem that the data of the position of the switch equipment can not be sent to the protection and control device during checking and checking and debugging. When protecting the main transmission or dispatching the remote control of the main station and the backstage monitoring and control machine, it is not necessary to go to the scene to determine the position of the switch equipment once for each transmission or remote control, which greatly saves the verification and adjustment of the maintenance work and the time of a power outage of the equipment, and improves the reliability of the power supply of the grid. Reduce the negative impact on society.
