Abstract

The invention discloses an intelligent debugging system for intelligent substation automation equipment and an application method thereof. The intelligent debugging system for intelligent substation automation equipment includes intelligent debugging equipment and an intelligent acceptance signal simulation device. The intelligent debugging equipment is respectively connected with the intelligent acceptance signal simulation device and the intelligent substation signal simulation device The station control layer network, the remote motor connection of the intelligent substation station control layer, and the intelligent acceptance signal simulation device are respectively connected with the interval layer network and the process layer network of the intelligent substation; Automatic closed loop testing. The present invention can realize automatic closed-loop test of remote signaling, remote measurement and remote control preset test of the whole station by using vertical cross-layer network data analysis, and can be used to realize the comprehensive automatic control of each function index and performance index of bay layer equipment and station control layer equipment. In order to intuitively and accurately locate the cause and location of the fault, improve the acceptance quality and efficiency of the intelligent station, and ensure the reliable operation of the intelligent station.

Description

technical field [0001] The invention belongs to the technical field of intelligent debugging of substation automation equipment, and specifically relates to an intelligent debugging system of intelligent substation automation equipment and an application method thereof, which can be used for automatic closed-loop testing of intelligent substation telemetry, remote signaling, remote control and other tests. Background technique [0002] The acceptance test of the intelligent substation automation system lacks professional equipment and means.

[0002] The acceptance test of the intelligent substation automation system lacks professional equipment and means. The acceptance process needs to involve process level equipment, bay level equipment, station control level equipment and telecontrol master station, as well as process level communication, station control level Therefore, in the acceptance test of the intelligent substation automation system, the requirements for the professional skills of the acceptance personnel are very high and the scope is very wide. Simulate the source output of telemetry and remote signaling. At the same time, it is necessary to check whether the protection, measurement and control equipment at the bay layer correctly receive and process the SV and GOOSE signals output by the equipment at the process layer, and convert them into corresponding DL / T860.8 protocol data and station control. layer device and / or telecontrol device for data interaction, and also check whether the telecontrol device correctly converts the DL / T860.8 protocol data into the corresponding 101 or 104 protocol to interact with the telecontrol master station, in this series of processes In the absence of professional test equipment, testers can only output through traditional standard source equipment or protection test equipment, and then when abnormalities are found, manual packet analysis and diagnosis are performed through general-purpose software such as WireShark, which requires testers The structure, composition, mechanism, and process of various messages are very clear and well understood, and test analysis can be carried out. However, it is difficult for ordinary testers to fully understand all protocols and messages. Therefore, there is currently a lack of In the case of professional testing tools, on-site acceptance has extremely high requirements for testers in terms of automation communication protocols. At the same time, even professional testers have very low efficiency in the manual analysis process, which often leads to smart substation automation. The acceptance test period of the system has been delayed again and again, and it is difficult to complete the quality and quantity as scheduled
