Embodiment Construction

[0027] The logical loop expansion method based on the SCD file provided by the present invention expands the description of the logical link, realizes the unified modeling of the relevant data of the logical link, and ensures the safety and integrity of the secondary loop configuration information in the SCD file to the greatest extent. sex, consistency. The method comprises the following steps: defining a uniformly expanded logical node (LN) to represent a logical link; prescribing the logical link in the ICD file; determining the order of the logical link according to the virtual terminal connection relationship; and sequentially associating to each logical link LN object.

[0028] The specific steps of the logical circuit expansion method based on the SCD file are as follows:

[0029] In step (1), the logical link is described by a unified and expanded logical node (LN) class, and a logical link should be modeled as an LN object; the unified and expanded logical node class ...

Abstract

The invention discloses a logic loop expansion method based on an SCD (Substation Configuration Description) file. The method comprises the following steps of defining a uniformly expanded logic node for expressing a logic link; presetting the logic link in an ICD file; determining the logic link sequence according to the virtual terminal connection relationship; and sequentially performing association to each logic link LN object. The method provided by the invention has the advantages that the description of the logic link is expanded; the uniform modeling of relevant data to the logic link is realized; the security, the completeness and the consistency of secondary loop configuration information in the SCD file are ensured to the maximum degree; and important significance is realized on improving the design and operation and maintenance efficiency of an intelligent transformer station, reducing the operation management wrong risk of the intelligent transformer station and guaranteeing the secure and healthy operation of a power system.

Description

technical field [0001] The invention relates to a logical circuit expansion method based on an SCD file, and belongs to the technical field of intelligent substations. Background technique [0002] The core technological innovation of smart substation is to use digital transmission technology (optical fiber Ethernet) to replace the secondary cables that have been used in conventional substations for many years. In terms of logical relationship, the publication and subscription mechanism of GOOSE / SV messages is used to replace the terminal connection relationship in conventional substations, and it is described in the system configuration description (SCD) file through the substation configuration description (SCL) language defined in IEC61850-6 . The fundamental changes in the form of secondary circuits in smart substations brought about by network technology provide the necessary technical foundation for data sharing and equipment interoperability. Various aspects such as...
