Description
Technical Field
The invention belongs to the technical field of smart power grids, and relates to a physical configuration system visualization method and system based on SCD files.
Background
With the construction of smart grids in China, the transformation from conventional substations to intelligent substations is also greatly promoted. After the transformer substation is intelligentized, the original automatic system is changed into a three-layer structure of a station control layer, a spacer layer and a process layer from a station control layer and a spacer layer. The structure of the station control layer and the bay layer of the intelligent substation is basically consistent with that of a conventional monitoring system, and the newly added process layer is used for completing the acquisition of the switching value and the analog value of primary equipment, the execution of a control command and the like. The process layer network is equivalent to a secondary cable of a conventional transformer substation, and the traditional cable connection is replaced by the optical cable, so that the existing wiring is greatly simplified.
A secondary loop information transmission medium between an intelligent control cabinet at a process level of an intelligent substation and a device cabinet at a spacing layer of a secondary device room cannot correctly and completely express an optical fiber loop or describe and transmit detailed physical loop and logic loop information by adopting an optical fiber to replace a traditional control cable nameplate mode. The virtual circuit logic information and the actual physical connection circuit lack correlation management, the virtual circuit and the actual physical connection circuit are difficult to correspond, and visual expression forms and quick reference modes are also lacked, so that the management of the whole life cycle of the intelligent substation is not facilitated, and the efficiency improvement of daily work is also not facilitated.
At present, an intelligent substation adopts a digital mode to build a communication network system of secondary equipment, which is based on a series of standards of 'DL 860 substation communication network and system' in the power industry standard of China and other standards derived on the basis of the series of standards. DL 860 specifies an SCL file to describe the configuration of the substation, which is classified into 4 classes, i.e. an SSD (EC 61850 system spec I cat I on Descr I pt I on, system specification file) file describing the substation specification, I CD (I ED Capab I ity Descr I pt I on, I ED capability description file) file describing I ED (I index of engineering file indexing) capability, a SCD file describing the complete configuration of the substation, and a C id file describing a single I ED configuration. Because an SCD (substat i on control i configuration i on descr i pt i on, total station system configuration file) file describes the configuration of a total station, it is concerned about both in the station building and in the operation maintenance and the extension and reconstruction after the commissioning of a transformer station, and the SCD file is a text file based on the XML specification, has huge content and complex structure, is difficult to read and understand, and the logical loop information and the real loop information described by the SCD file cannot be directly mapped to form association in an actual scene.
Analysis and display achievements aiming at SCD files are more, mainly focusing on the imaging technology of a virtual circuit, and lacking in real circuit visualization research on a secondary system. In engineering practice, the signal flow direction described in the virtual loop and the specific optical fiber through which the signal flow passes and the information flow carried in the optical fiber are often required to be known, and the prior art is lack of a visualization means for the information and accuracy verification of actual engineering construction and file description.
