    摘 要:針對(duì)傳統(tǒng)單一接地故障選線裝置的選線效果不理想,分析了智能變電站小電流接地故障選線系統(tǒng)發(fā)展趨勢(shì),并提出了一種新的小電流接地故障選線系統(tǒng)。該系統(tǒng)結(jié)合智能變電站的組成結(jié)構(gòu)和數(shù)據(jù)傳輸特點(diǎn),由間隔層保護(hù)測(cè)控裝置完成對(duì)線路信號(hào)的采集,利用GOOSE 報(bào)文傳輸機(jī)制通過(guò)站控層網(wǎng)絡(luò),上送故障選線裝置,由該裝置進(jìn)行故障判斷。仿真結(jié)果表明該系統(tǒng)可快速、準(zhǔn)確地判斷出故障線路。

    Abstract: Aiming at the unsatisfactory route selection result of traditional single grounding fault line selection device, this paper analyzed the development trend of small current grounding fault line selection system in intelligent substation and proposed a new kind of small current grounding fault line selection system. This system combined the intelligent substation composition structure with data transmission characteristics and finished the line signal acquisition through the interlayer protection device. By using the GOOSE message transmission mechanism through the station control layer network, the line signal was sent to the fault line selection device for fault judgment. The simulation results show that this system can judge the fault line quickly and correctly.
    Key words: small current grounding fault line selection; GOOSE transmission mechanism; simulation test; accuracy
