Research On Multi Protocol Conversion Technology Based On 61850 Protocol

The IEC61850 Protocol has been leading the development direction of substation system construction since its promulgation.It has been supported by many countries around the world and promoted smoothly.However,at present and even in the future,there will still be a certain degree of traditional regulatory equipment in the substation system and the popularity of the IEC61850 protocol also has a gradual process,so the protocol conversion gateway will exist for a long time.Aiming at the construction of substation automation system,especially the heavy-duty protocol conversion in the development and construction of the state monitoring field,this paper proposes a concept of multi-protocol conversion platform based on micro-service architecture model,and explores a new implementation method for the development of IEC61850 protocol conversion software.Firstly,on the basis of summarizing the application status of the IEC61850 Protocol at home and abroad,the research purpose and content of this topic are proposed.Based on the contrastive study of the traditional IEC61850 protocol conversion implementation method,this paper proposes the core idea of multi-protocol conversion: Maximize the decoupling of each protocol conversion module to form an independent service unit,and form the conversion relationship in a flexible configuration.Secondly,this paper presents a platform system design and technology implementation for multi-protocol conversion.At the design level,this paper focuses on the generality and maintainability requirements to deal with the ever-changing technical upgrading of substation systems.With the help of the micro-service architecture idea,each traditional protocol conversion module,mapping configuration module,data storage module,and IEC61850 service module are converted into uncoupled micro-service units.Each has a clear border,so that the entire agreement conversion platform has a good commonality and maintainability.Considering stability and scalability as the main considerations in technology implementation,this paper adopts the mature Spring Cloud micro-service technology framework in the industry to implement the platform architecture and improve the stability and scalability of the platform from multiple levels.Finally,this paper tests several IEC61850 multi-protocol conversion platforms.The Modbus protocol analog device access system is used for protocol data conversion functional testing;the Python analog service is used as a third-party component access system for platform scalability testing.Both test results verify the validity and reliability of the IEC61850 multi-protocol conversion scheme,and can be applied to the transformation of the traditional protocol and the IEC61850 protocol within the substation system.
