Data transmission method of traction network fault location system based on goose

Abstract

The invention discloses a GOOSE-based traction network fault distance measurement system and a data transmission method thereof. The GOOSE-based traction network fault distance measurement system comprises a fault distance measurement device arranged at a substation and a fault distance measurement device arranged at a fault distance measurement station, wherein GOOSE is used to transmit a distance measurement start command and distance measurement data in a broadcasting mode between the fault distance measurement device arranged at the substation and the fault distance measurement device arranged at the fault distance measurement station; peer-to-peer communication is directly carried out between the fault distance measurement device arranged at the substation and the fault distance measurement device arranged at the fault distance measurement station; a feeder unit of the substation sends a fault start GOOSE message to the fault distance measurement device arranged at the substation through GOOSE; and the fault start GOOSE message triggers the fault distance measurement function of the fault distance measurement device arranged at the substation.

Description

technical field [0001] The invention relates to railway ranging technology, in particular to a GOOSE-based traction network fault ranging system and a data transmission method thereof. Background technique [0002] The fault location system is the core equipment of the traction power supply system. Its main function is to accurately locate the nature of the fault and the actual fault point when the catenary or locomotive fails. It is crucial to shorten the maintenance time and ensure the normal operation of the high-speed rail. important role. In the existing fault location system, the fault location devices among all fault location devices realize data transmission through the distance measurement communication management machine. The data between the two fault location devices can only be reached after two protocol conversions. The system structure is complex, there are many communication links, and the system reliability is not high. [0003] In the existing traction ne...
