Virtual secondary circuit examination method between intelligent station intelligent device virtual terminal and device

Abstract

The present invention discloses a virtual secondary circuit examination method between an intelligent station intelligent device virtual terminal and a device. The method comprises a base model defining step of defining the model classes used in project template description, wherein the model classes comprise an intelligent device class, an input virtual terminal class, an output virtual terminal class, an input virtual terminal set class, an output virtual terminal set class, a virtual secondary circuit class, a virtual secondary circuit group class, a spacing class or a substation design scheme rule class, a step of applying the model classes, combining the related standard regulation specification and typical design specification requirements of the power industry and defining various types of project templates, wherein the defining of the various types of project templates concretely comprises defining a standard intelligent device template, defining a spacing class template and defining a substation design scheme rule template, and a step of using various types of project templates to examine an SCD file. According to the method, after the substation project design construction is completed, various file errors can be examined in advance, and the efficiency of intelligent substation design review is ensured.

Description

Technical field [0001] The invention relates to a method for auditing virtual terminals of intelligent devices of intelligent stations and virtual secondary circuits between devices. Background technique [0002] Smart substations (including digital substations) use the latest communication technology and information processing technology. Compared with conventional substations, their structure and morphology have undergone revolutionary changes. In conventional substations, information communication between devices is realized using cables. The circuit information between the terminals is described by design drawings. In the smart substation, the information communication in the smart substation in accordance with the IEC61850 standard is realized through network signals, and the circuit information between the terminals is described in SCD files that comply with SCL semantics and syntax. To describe. In order to enable professionals to understand, the concept of virtual termin...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic SCD documents are basically based on the virtual terminal semantics by engineering designers or debuggers, who associate the input virtual terminals with the output virtual terminals one by one to form a virtual secondary circuit, and write the virtual secondary circuit into the SCD file. Each specific substation project needs to be done again, resulting in a large workload for circuit configuration of each substation and poor reusability
