Problems solved by technology

However, the comparison efficiency based on the SCD file is not high enough. The SCD file contains the data information, data type, communication parameters, control block parameters, etc. of the IEDs of the whole station, and the file size may reach hundreds of megabytes.
If the graphical information of a single IED is completely extracted from the SCD file, not only the display speed is limited, but also a lot of CPU resources and memory resources will be consumed

Abstract

The invention discloses an SCD version comparison method based on a standard intermediate process file, and a four-layer graph-based virtual circuit visual comparison method of an intelligent substation. The graphical method is more efficient to realize the comparison of virtual circuits step by step from top to bottom. Maximize the security, integrity, and consistency of virtual circuit configuration information, change the inefficient and fragile status of relying on manpower to ensure the correctness of virtual circuit configuration, thereby ensuring and improving the safe operation level of smart substations, and shortening system commissioning Time, reduce the pressure of system operation, and reduce the maintenance cost in the whole life cycle of smart substation.

Description

technical field [0001] The invention relates to the field of SCD version management of intelligent substations, in particular to an SCD version comparison method based on standard intermediate process files. Background technique [0002] In the smart substation, the system configuration description (SCD) file replaces a large number of secondary circuit drawing designs. The SCD file contains the operation information of all equipment, including the data information, data type, and communication parameters of each IED (Intelligent Electronic Device) in the station. , control block parameters, circuit relationship between devices, especially key connection relationships such as tripping and closing, sampling, etc. In the process of construction, commissioning, operation and maintenance, maintenance, renovation and expansion of substations, it is necessary to repeatedly modify and verify the information content of SCD files, so that more SCD versions will be formed. In project ...
