Design And Implementation Of A Secondary Design System Of Intelligent Substation Based On Micro-service Software Architecture

With the concept of smart grid,smart substation as the most important part of the smart grid,the design pattern has undergone tremendous changes,the original design model is no longer meet the smart grid standards.The design of the intelligent substation is divided into a design part and a second design part.The secondary design is a work of measuring and protecting the intelligent device on the basis of a design.Therefore,the design of the secondary intelligent substation is designed the process occupies a very important position.As the original design model has been unable to meet the new changes and design requirements,so for the design staff to facilitate the design of fast and easy platform is imperative.Based on the research on the current knowledge of intelligent substation and the present situation of substation design,this paper firstly analyzes the requirements of the system from the aspects of function and performance,analyzes and designs the architecture of the system.We implemented an intelligent substation secondary design system based on micro service software architecture.This paper introduces the design of the system architecture,the main technology used,the design and implementation of the system,and the testing of the system from the aspects of the client,the server and the communication between the two.After the promulgation of the latest power system the global standard IEC61850,the second design of the virtual terminal connection,the secondary system equipment communication between the original cable into a small amount of fiber,resulting in the design process is not visible,the system does not depend on AutoCAD,but the use of SVG(Scalable Vector Graphics,scalable vector graphics)technology to achieve the virtual terminal and other equipment or signal visual design.In the case of a large number of devices,the workload will increase and prone to error,post-modification work is also very complex,the system’s virtual loop automatic connection function to effectively solve this design problem.In the device selection module of the system,the import and replace function of the ICD(IED Capability Description)file are provided.No need to wait for the manufacturer to provide the ICD file for the secondary design,that is,the template Design method.The model library of the system provides a typical model of typical design,which greatly reduces the workload of the user.In order to ensure the design work can be carried out smoothly,the traditional Web architecture model needs to purchase a large number of servers,resulting in a waste of resources,so the system uses micro-service distributed Web Architecture model to design and implementation.The design system provides a visual design platform for the secondary design of the intelligent substation,and can reduce the workload and error rate of the former design mode,and finally generate the whole station configuration file expected by the design institute,and adopt the micro service as the whole system architecture,And use the thriftRPC remote procedure call frame to achieve the call between services to ensure the safety and stability of the entire system.
