A method for converting sv messages between substations to r-sv messages

Abstract

The invention discloses a method for converting an SV message between substations to an R-SV message, comprising the following steps: S1, forming an R-SV message template according to the basic structure of the R-SV message; S2, converting The R-SV message template is divided into three parts: SV message information, routing information and verification encapsulation information; S3, mapping the obtained SV message information to the corresponding position of the R-SV message template in memory; S4, Extract routing information from SCL file; S5, the routing information that step S4 extracts is filled into the message domain that R-SV message is relevant with routing information, and puts into internal memory; S6, the proofreading of filling R-SV message template Verify package information. The invention breaks through the limitations of traditional SV message transmission inside the substation, and can quickly construct R-SV messages according to the original SV message, thereby realizing the transmission of information between multiple substations and the interconnection of information between substations , intercommunication.

Description

technical field [0001] The invention belongs to the technical field of power system protection, control and automation, and in particular relates to a method for converting SV messages between substations to R-SV messages. Background technique [0002] With the in-depth development of the smart grid, the power information system will rely more on the communication network to transmit information representing the state of power protection, control and automation and its commands in the form of messages. The substation event (SV, Sampled Value) message oriented to general objects, as an important message of the smart substation to represent the operation commands such as tripping and closing of the circuit breaker and the position information of the circuit breaker [1-2], will also be limited to the expansion of the original station. To the entire power system, an R-SV message with routing function is formed. [0003] SV messages are only limited to transmission inside the su...

But the current R-SV message like Seyed Reza Firouzi, Luigi Vanfretti, Albert Ruiz-Alvarez, et al. Interpreting and implementing IEC 61850-90-5Routed-Sampled Value and Routed-GOOSEprotocols for IEEE C37.118.2compliant wide-area synchrophasor data transfer [J]. Electric Power Systems Research, 2017, 144. The R-SV message mentioned in the literature needs to be directly implemented with the help of a special communication protocol stack, and does not have the ability to convert SV messages to R-SV messages.
