A substation secondary system resource allocation method and system

Abstract

The invention discloses a secondary system resource allocation method and allocation system through the whole life cycle of the transformer substation. The equipment combination and the function composition of the transformer substation secondary system are abstracted to the equipment and facility resource objects of the transformer substation secondary system, then the minimum unit of the resources is defined, the correlation between various resource classes is described by using the UML language, and the XML description grammar of the resources is defined according to the UML class diagram so that finally XML description of the transformer substation secondary system resources can be realized. The description mode compatible with IEC61850 is adopted so that the present information resources of the transformer substation can be utilized to the greatest extent and can be directly utilized for the subsequent links of field debugging, operation and maintenance and expansion and reconstruction to realize sharing of information, the work efficiency of the links can be enhanced and the conditions can be provided for further integrated information application.

Description

technical field [0001] The invention relates to the technical field of electric power automation, in particular to a resource allocation method and system for a substation secondary system. Background technique [0002] With the application and promotion of the IEC61850 standard in the field of substation automation, the problem of information interaction and interoperability between intelligent electronic devices in substations has been improved to a certain extent. Although, IEC61850 uses SCL configuration language to describe the communication resources of substation equipment, which can realize the sharing and configuration of substation communication information. However, it focuses on data modeling and interoperability of intelligent electronic equipment in substations, and lacks specifications for related information such as equipment and facilities, which is not conducive to the acquisition, sharing and utilization of these information, limits the application of inte...

Problems solved by technology

In the stage of substation design and planning, equipment manufacturers need to provide equipment specifications, which contain information such as equipment size, size, interface, composition, layout, and functions. Due to the lack of a unified description method, they cannot be directly used by design tools and require manual input. Establish an information base; in the stage of integration and debugging, it is necessary to rely on the design products of the design unit, usually paper or electronic CAD drawings, including physical and logical relationships between devices, optical cables and cable connections of devices, and engineering semantics of signals, etc. , the integrated debugging tool cannot directly use the information, it needs to be manually configured, the efficiency is extremely low, and the correct rate of configuration is not high; in the operation and maintenance phase, it is necessary to analyze and troubleshoot equipment failures, which depends on the comprehensive utilization of various information in the station , such as the diagnostic information of the device itself, the alarm information in the background, and the connection relationship and spatial distribution between the devices. Under the condition of large-scale operation and maintenance, in order to find this information, it is necessary to read a large number of drawings, which is inefficient and not conducive to timely processing of faults.

Similarly, the current various integrated configuration tools can only process information defined by SCL such as ICD and SCD, and lack the ability to process equipment physical resource information
