Research and Application Analysis of Communication Protocol between Power System Protection Device
In order to improve communication efficiency,aiming at the problems and challenges of existing communication protocols,the performance characteristics of standard protocols or proprietary protocols such as IEC 61850,Modbus and Distributed Network Protocol 3(DNP3)are compared.On this basis,a design scheme of unified communication protocol is proposed to break the communication barrier between protection devices of different manufacturers.Through statistical analysis and comparison of data frame structure,transmission mode and delay in power system protection device communication,its performance is discussed.On this basis,the frame structure and transmission rules are optimized to reduce data transmission delay and improve communication efficiency.In addition,the protocol shows good compatibility,supports seamless access of various devices and systems,and has good wide applicability in practical applications.
