SCD version comparison method based on standard medium process document

Abstract

The invention discloses an SCD version comparison method based on a standard medium process document. An intelligent transformer substation virtual loop visualizing comparison method is based on a four-layer graph. The method comprises four layers, namely a device, a link, a communication parameter and a virtual loop. Comparison of the virtual loop is efficiently and gradually achieved from top to bottom in an imaging mode. The security, the integrity and the consistency of virtual loop configured information are maximally guaranteed, the inefficient and weak current condition that the virtual loop configuration accuracy is guaranteed by manpower is changed, the safe operation level of an intelligent transformer substation is guaranteed and improved, the system commissioning time is shortened, the system commissioning pressure is lowered, and the maintenance cost in the whole service cycle of the intelligent transformer substation is lowered.

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 ...

AI Technical Summary

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
