Method and device for realizing programmed operation of transformer station based on SVG (Scalable Vector Graphics) technology

Abstract

The invention discloses a method and device for realizing programmed operation of a transformer station based on an SVG (Scalable Vector Graphics) technology, belonging to secondary system equipment of an intelligent digital transformer station. According to the method, a remote scheduling centre and a station control background access a programmed operation ticket device through an HTTP (Hyper Text Transport Protocol); executions of all measurement, control and protection devices in the transformer station can be controlled by using a programmed operation device; the problems of complexity, high maintenance workload and the like resulted from respective programmed operation ticket systems installed in the remote scheduling centre and the station control background respectively in the prior art can be solved; the method realizes that the remote scheduling centre and a background system of the transformer station share the functions of configuring, checking, issuing, simulating and executing of the programmed operation ticket, so that one transformer station only has an execution file of the programmed operation ticket; an embedded type industrial network processor and a back insertion type modularized design are used in the device using the method; and therefore, the programmed operation is safer, steadier and more reliable.

Description

Technical field [0001] The invention relates to a method and a device for implementing programmed operation of a substation based on SVG (scalable vector graphics) technology, and belongs to secondary system equipment of an intelligent digital substation. Background technique [0002] As one of the basic links of the smart grid, the smart digital substation is the hub of smart grid energy transmission, the most important source of grid operation information, the execution place of smart grid operation control, and the foundation and key to building a strong smart grid. The intelligent digital substation has a unified data model and communication platform for the entire station. Digital communication is realized between the primary electrical equipment and the secondary electronic equipment in the substation, and the interoperability between intelligent devices is realized on this platform. [0003] At present, the programmed operation ticket system used in the substation is realize...

AI Technical Summary

Problems solved by technology

[0005] (2) The remote dispatch center and substation background system must establish their respective programmed operating systems, resulting in complex systems and huge maintenance workload;

[0006] (3) The programmed operation ticket file adopts a self-defined internal format, and the interoperability and compatibility of the programmed operation files of various equipment manufacturers are poor;

[0007] (4) Each compartment layer measurement and control device in the substation stores the programmed operation ticket file, resulting in inconsistent versions;

[0008] (5) The remote dispatching center cannot effectively modify the protection setting value of the substation secondary equipment, switch the setting value and cancel the protection function;

[0009] (6) The remote dispatch center cannot track and monitor the programmed operation process, and cannot grasp detailed and accurate command execution results
