Solution Overview

Problem

Current preventive diagnostic systems for GIS lack integration with substation automation systems that adhere to IEC 61850 standards, hindering seamless communication and efficient operation.

Innovation Solution

A preventive diagnostic system for GIS is designed to comply with IEC 61850 by implementing a logical node, logical data acquisition system, and common data class, mapping data objects into Manufacturing Message Specification (MMS) for MMS communication, and using an IEC 61850 COM client to facilitate communication between the DAS and CCU, enabling data transmission in IEC 61850 format.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If IEC 61850 is applied to the preventive diagnostic system for GIS, then communication compatibility with substation automation systems is improved, but device complexity increases due to implementation of logical nodes, data mapping, and protocol compliance

Engineering Contradiction:
Improvecommunication compatibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs an IEC 61850 COM client as an intermediary component that facilitates communication between the preventive diagnostic system and substation automation systems. This client handles the complex protocol mapping and data translation, allowing the core diagnostic functionality to remain relatively simple while achieving full IEC 61850 compatibility through this dedicated interface layer.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If data objects are mapped into MMS for MMS communication, then communication standard compliance is improved, but manufacturing precision of data structure increases

Engineering Contradiction:
Improveprotocol complianceVSAvoiddata structure precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by transforming data objects from their original structure into MMS-compliant formats. This involves changing data types, structures, and encoding parameters to match IEC 61850 specifications, enabling standard-compliant communication while maintaining the integrity and precision of the underlying diagnostic data through systematic parameter transformation.

Inventive Principle:

AI summary

According to an embodiment of the present disclosure, there is provided a preventive diagnostic system for a GIS that includes a plurality of data acquisition systems DAS's (20), a central communication unit CCU (30), and a local server (40). The DAS (20) generates an ICD file representing a content of the configuration of the DAS (20) using a logical node designed for the preventive diagnostic system for a GIS and delivers the ICD file to the CCU (30), and the CCU (30) performs a network connection so as to communicate with the DAS (20) in compliance with IEC 61850 based on a content of the ICD file delivered from the DAS (20). According to the embodiment of the present disclosure, by applying IEC 61850 to the preventive diagnostic system for a GIS, smooth integration with a substation automation system and an efficient operation can be achieved.
