Intelligent SCD loop checking method and device

Abstract

The invention relates to an intelligent SCD loop checking method and device. The method comprises the steps that a signal semantic feature dictionary database is established according to a functional loop and semantic features of functional signals of intelligent SCD; the functional loop between intelligent devices of the intelligent SCD is analyzed; the signal semantic feature dictionary database is used for detecting the functional loop in the intelligent SCD. Therefore, the reliability of finally obtained detection results and checking reports is high, and the method is an effective method for design examination of an intelligent transformer substation, so that the design and debugging period of the intelligent transformer substation is greatly improved.

Description

technical field [0001] The invention relates to a verification method and device, in particular to a verification method and device for an SCD circuit of an intelligent substation. Background technique [0002] Smart substations take SCD files as the core. Whether it is the design process of smart substation construction, the transfer of configuration files, or the modification of configuration files during the maintenance of smart substations, task executors and configuration file managers need to check the correctness of SCD files. Check. SCD (Substation Configuration Description), the system configuration file of the whole station describes the instance configuration and communication parameters of all IEDs, the communication configuration between IEDs, the primary system structure of the substation, and the signal contact information, which is a unified data source for the whole station. [0003] At present, smart substations have entered the stage of large-scale constr...

Problems solved by technology

In the face of a large amount of design and maintenance work, the task performers and managers of the relevant units have no energy to devote themselves to the correctness inspection of each SCD file. The problem of low efficiency of manual inspection has become the focus of smart substation construction and maintenance. one of the main bottlenecks

[0005] Publication number CN 104951620A "Smart substation configuration file SCD file audit method based on business rules" and public number CN 105184659A "Intelligent station intelligent device virtual terminal and virtual secondary circuit audit method between devices" proposed a virtual secondary circuit of SCD files based on business rules Secondary circuit audit method, but this method has very high normative requirements for the virtual terminal name of the device, that is, if the virtual terminal name is not completely consistent with the specified standard terminal name, the method will fail: therefore, it must strictly follow the relevant technical specifications and uniformity of standards

[0006] At present, the protection devices used in a large number of smart substations in operation and under construction cannot fully meet the uniformity requirements of the above technical specifications and standards, and cannot guarantee that the names of the virtual terminals of smart devices from various manufacturers are completely consistent with the standard names; therefore, if you want to develop smart For the loop audit of substation SCD files, it is urgent to adopt a verification method with strong flexibility and adaptability
