Cluster measuring and controlling device for spacer layer equipment of intelligent substation

Abstract

The invention relates to a cluster measuring and controlling device for spacer layer equipment of an intelligent substation. The cluster measuring and controlling device comprises two sets of measuring and controlling sub-equipment having identical configuration of media boards and being standby equipment for each other, wherein the board configuration of each set of measuring and controlling sub-equipment comprises a power supply board, a process layer interface board with an SV/GOOSE receiving interface and a GOOSE transmitting interface, an input board and a main processing board; and the power supply board, the process layer interface board and the input board of each set of measuring and controlling sub-equipment are electrically connected with the main processing board respectively.After replacement of an existing measuring and controlling device with the cluster measuring and controlling device, the number of measuring and controlling devices in an interval layer is greatly reduced; the installation, debugging, operation and maintenance cost of a monitoring system is lowered; and the outstanding problem of no indepdnent stand-by measuring and controlling device in the existing monitoring system is solved.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular relates to a device cluster measurement and control device for an intelligent substation bay layer equipment. Background technique [0002] At present, the construction of smart substations generally adopts the "three-layer equipment, two-layer network" model, that is, process layer equipment, bay layer equipment, station control layer equipment, process layer network, and station control layer network. Although the smart substations that have been built have made great progress in equipment, construction and operation and maintenance management, due to the scattered functions of the monitoring system, the information network in the station is relatively complicated, which not only increases equipment investment, but also reduces the reliability of the substation. There are still problems in the concept of smart substation construction, technological inn...

AI Technical Summary

Problems solved by technology

[0003] At present, the smart substation monitoring adopts the configuration mode facing the bay layer; the station control layer has many types of equipment, scattered function settings, complex information interaction, low function application efficiency, and low operation reliability; the number of bay layer equipment is large, the function is single, and there is no redundancy. In case of failure, the equipment information collection function will fail, resulting in incomplete real-time data; the entire station lacks effective operation monitoring and maintenance tools, insufficient support for substation equipment inspection, on-site operation, and maintenance services, and on-site operation and maintenance personnel cannot monitor in time and troubleshooting

At present, the main technical problems in the intelligent substation automation system are: the scheme of configuring the measurement and control devices according to the interval layer results in a large number of measurement and control devices, high construction costs, and a large amount of maintenance; there is no backup of the measurement and control devices. won't work
