Integrated method and integrated device of SCD (System Configuration Document) of transformer station

Abstract

The invention provides an integrated method of an SCD (System Configuration Document) of a transformer station. The integrated method comprises the steps of inputting an ICD (Interface Control Document), wherein the ICD comprises a header, a communication, a substation, an IED (Intelligent Electronic Device) and a data type template; decoupling a station level according to the ICD, and obtaining a station level ICD; decoupling a process level according to the ICD, and obtaining a process level ICD; inputting the station level ICD, configuring a station level communication parameter and a record control block, and obtaining a station level SCD; and inputting the process level ICD, configuring a GSE (Generis Substation State Event) of the process level, an AMV (Sampled Measured Value), a GOOSE (General Object Oriented Substation Event) and SV (Sample Value) control blocks and inputs, and obtaining a process level SCD. The invention also provides an integrated device of the SCD of the transformer station. According to the integrated device provided by the invention, the integrated efficiency of the SCD can be increased.

Description

technical field [0001] The invention relates to the field of smart substations, in particular to a method and device for integrating substation SCD configuration files. Background technique [0002] The basic features of a digital substation include: the application of electronic transformers and intelligent primary equipment, unified modeling based on the IEC61850 standard system, and secondary information network transmission, etc. A very attractive prospect. In recent years, my country has carried out a series of digital substation practices, accumulated a large number of successful experiences and cases, and effectively promoted the development and promotion of this new technology in my country's power grid. [0003] The digital substation takes the primary and secondary equipment of the substation as the digital object, based on the high-speed network communication platform, and realizes information sharing and equipment interoperability through the standardization of ...

Problems solved by technology

Its core technological innovation is to use network technology to replace traditional secondary wiring to transmit digital and analog signals. The original direct, visible, mutually decoupled, concrete secondary wiring will be replaced by an indirect, highly coupled, abstract network data stream. , and through the substation configuration description (SCL) language defined in IEC61850-6, all the configuration information of the whole station is statically described in the system configuration description (SCD) file, but the SCL language is based on XML syntax, configuration information such as logical relationships between devices The expression is relatively obscure, and users need to have certain professional knowledge and in-depth training to master it. It is difficult for ordinary users to quickly view and configure the logical relationship between IEDs

[0004] At present, there is a very prominent problem in the integration process of the digital substation system: the process layer and the station control layer are mixed together for configuration, and the configuration and integration between the two interfere with each other; especially when the configuration is about to be completed or has been completed, if the It is only necessary to modify the configuration of the process layer or the station control layer, which will lead to changes in the entire SCD file. There is no effective means of evaluating whether the process layer or the station control layer has been modified, resulting in the need to re-test the configuration file completely, and the integration efficiency is very low.
