Background
According to the requirements of substation construction planning and national center on professional management of intelligent substation secondary protection control equipment of national grid companies, new substations in 2016 and later are completely built according to an intelligent substation mode, a communication network of the intelligent substation replaces a secondary loop of conventional physical wiring, a small amount of optical fibers replaces a large amount of cables, and the functions of the equipment are really released from a hardware loop.
With the development of the online monitoring and diagnosis technology of the protection device, the secondary device visualization and intelligent diagnosis system is composed of a data acquisition unit and an online monitoring module, as shown in fig. 1, wherein the online monitoring and diagnosis module is deployed in a monitoring host in an area i. The data acquisition unit acquires process layer data through a process layer network; the on-line monitoring module acquires all-station data from the data acquisition unit and the station control layer network for analysis and processing, and realizes on-line monitoring and diagnosis functions.
Because the communication between the spacer layer device and the process layer equipment is endless and non-wiring, all information is hidden in the optical fiber; in addition, although the SCD includes communication information between all devices in the total station, the SCD cannot cover access information of the total station in the switch and device sending end information in the process layer network, and cannot completely display secondary loop information centered on the device, and cannot further prompt virtual loop information in any optical fiber link.
According to the requirement of visual display of a secondary circuit in the operation of a power grid, if the equipment access information of a switch and the device sending end information of a process layer network can be visually and visually displayed in a physical link, all logic circuits taking the device as a center and all logic circuits in a process layer network optical fiber link are established and displayed, the physical link and the logic circuits are effectively combined for visual display, and the visual display is greatly favorable for improving the operation, maintenance and overhaul working efficiency.
