Solution Overview

Problem

Current methods for generating engineering topologies of digital substations based on international standards, such as IEC 61850, are complex and often require manual processing, making it difficult for engineers to automatically generate engineering design tasks conforming to these standards, especially when dealing with the SSD file that describes substation topology connections.

Innovation Solution

A method and device that utilize a single-line diagram generation module to create a single-line diagram of a digital substation, followed by a topology conversion module to convert this diagram into an engineering topology conforming to international standards, with verification by a topology verification module to ensure compliance, and finally generating a system specification description file.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual processing is used to generate engineering topology conforming to international standards, then the engineering design can be completed with high precision, but the time consumption and complexity increase significantly

Engineering Contradiction:

Improveengineering topology generation accuracyVSAvoidengineering design time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical processing with automated computer-based processing. The system uses software modules to automatically generate engineering topology from single-line diagrams, converting manual engineering tasks into automated digital processes that conform to IEC 61850 standards without requiring extensive manual intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates standardized templates and models for engineering topology generation. By using pre-defined patterns and reusable components that can be copied and adapted, the system maintains high precision while reducing the time required to create new engineering designs from scratch

Inventive Principle:

Principle #26Copying

2Productivity

If automated generation is implemented for engineering topology, then the productivity increases and time is reduced, but the complexity of the system increases

Engineering Contradiction:

Improveengineering design productivityVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the engineering topology generation process into distinct modular functional modules: single-line diagram generation module, topology conversion module, and verification module. Each module handles a specific aspect of the generation process, making the overall complex system manageable through clear separation of concerns and independent functionality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediate data structures and conversion layers between different representation formats. The topology conversion module acts as an intermediary that transforms single-line diagrams into engineering topology conforming to IEC 61850 standards, simplifying the interface between different system components and reducing overall system complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If comprehensive verification is performed to ensure international standard compliance, then the reliability of engineering topology is improved, but the processing time and complexity increase

Engineering Contradiction:

Improveengineering topology compliance reliabilityVSAvoidverification process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent performs verification checks during the topology generation process itself rather than as a separate post-processing step. The verification module continuously validates the generated engineering topology against IEC 61850 standards as it is being created, ensuring compliance is built-in from the beginning rather than added later

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The verification module provides immediate feedback on compliance status during the generation process. If the generated topology does not conform to international standards, the system can automatically adjust or alert the user, creating a closed-loop verification process that improves reliability without requiring complex manual rework

Inventive Principle:

Principle #23Feedback

AI summary

The present invention relates to a method and device for generating an engineering topology of a digital substation. The method may include: generating, by a single line diagram generation module, a single line diagram of the digital substation based on input information regarding a plurality of substation component devices and connection relations therebetween; converting, by a topology conversion module, the single line diagram of the digital substation into an engineering topology conforming to international standards by use of conversion conditions stored in a topology component management module; verifying, by a topology verification module, whether the engineering topology is suitable for the digital substation based on the international standards; and generating, by an international standard file generation module, a single line diagram engineering file of the digital substation as a system specification description (SSS) by use of the verified engineering topology.
