Abstract

The invention discloses an on-line breaker monitoring device based on a GOOSE message frame polymerization technology. The device comprises a switch state monitoring loop, an adjustment circuit, a first A / D conversion circuit, an FPGA (field programmable data array) and a DSP (digital signal processor) / ARM dual-core operation system, wherein the switch state monitoring loop is connected with the input end of the FPGA through the adjustment circuit and A / D conversion circuit; the output end of the FPGA is connected with the input end of the DSP / ARM dual-core operation system through the address bus of a data bus; the DSP / ARM dual-core operation system comprises an SDARM (synchronous dynamic random access memory), a FLASH, a serial interface, a JTAG (joint test action group) debugging port, anoptical Ethernet port, an Ethernet port, a reset watchdog, a second A / D conversion circuit, a crystal oscillator and a power supply. By using the device provided by the invention, the data transmission is quick in speed and reliable; and the device can meet the instantaneity requirement of massage transmission, reduce the expense on Ethernet protocol, and reduce the massage length and the massage transmission time relay.

Description

technical field

[0001] The invention relates to power system protection equipment, in particular to an online circuit breaker monitoring device based on fast message frame aggregation technology. Background technique

[0002] As an important primary device for protection and control functions in the power system, the circuit breaker's operation reliability is directly related to the safety and stability of the power system, and once a fault occurs, it will bring serious consequences. Conventional substations often use off-line routine tests to judge the operating status of circuit breakers. Preventive tests and planned maintenance have the disadvantages of blindness and high costs, and frequent operations and excessive disassembly will reduce the reliability of circuit breaker operations. In recent years, with the development of smart grid and digital substation technology, a smart circuit breaker integrating detection, control, communication and other functions has received...
