Embodiment Construction

[0029] The present invention is a method for realizing SCD decoupling by adopting extended tags. The method combines the characteristics of SCL language, and for the decoupling object, adds the configuration information in the SCD file with a Private tag in XML format, and for the decoupling mode in the Private tag, Attribute marking is performed to easily realize the decoupling of SCD according to business and interval. Said method comprises the following steps:

[0030] Step 1, according to the SCD decoupling method: business direction, interval method, primary and secondary equipment topology relationship, respectively define the types of the above methods;

[0031] The decoupling method, the scheme of decoupling mode by interval is:

[0032] a. Under 220kV voltage level: busbar interval configuration, bus coupler interval configuration, and line interval configuration;

[0033] b. Main transformer interval configuration, public interval configuration;

[0034...

Abstract

The invention belongs to the technical field of process design and electric power automation, and particularly relates to a method for realizing SCD decoupling by adopting extension tags. An SCD decoupling scheme in the field of electric power automation is designed from the perspective of management control demands of professional management and reconstruction and extension of a substation on a configuration file. The method comprises the steps of classifying decoupling modes according to a business direction, an interval mode and a topological relationship between primary and secondary devices; by reference to SCL grammar, and in combination with the decoupling modes according to the business direction, the interval mode and the topological relationship between primary and secondary devices, defining an attribute and a format of a tag <Private>; performing Private tag instantiation on a decoupling object in an SCD file; and finally configuring the <Private> element tag in the SCD file. In combination with construction and maintenance processes of the intelligent substation, the SCD file is decoupled, so that the operation and maintenance capability of the intelligent substation is improved.

Description

technical field [0001] The invention belongs to the technical field of process design and electric power automation, and in particular relates to a method for realizing SCD decoupling by using extended tags. This method is to design the SCD decoupling scheme in the field of electric power automation from the perspective of the professional management of substations and the management and control requirements of configuration files for reconstruction and expansion. Background technique [0002] SCD (System Configuration Description) configuration file is the core object of smart power system management and control. As a descriptive file of modern smart substations, its importance is self-evident. Starting from the management and control requirements of configuration files for substation professional management and reconstruction and expansion, SCD decoupling adopts business-oriented logic decoupling and interval-oriented SCD Physically decouple the SCD. Regardless of the de...
