Abstract: The aim of this paper is to diagnose the dispatching data network fault. The D5000 system is taken as the example to design the graphical interface of the dispatching data network channel, and draw the mark call buttons on the wiring diagram for setting the key attributes. The script program was designed. A substation in S District is taken as the instance to judge the problem from the substation, and in combination with the main body design of the program, the command in Linux system is used to output the text. Based on the fault diagnosis and testing process, the fault of dispatching data network channel in F5000 system is judged, and the scientific test of the fault diagnosis function is conducted. The button in wiring diagram is clicked, in combination with the tips, to determine whether the dispatching data network channel is normal. Combined with the basic analysis of the remote operation and maintenance, a diversified business requirement is reflected, the reliability and security of the data network channel are improved. The dispatching data network test was realized by integrating with the running condition of the power grid dispatching data network channel. The application practice shows that the diagnosis method of dispatching data network channel fault in D5000 system is simple, and has less fault diagnosis time and high fault location accuracy.
Keywords: dispatching data network channel; fault diagnosis; power grid dispatching technology; D5000 system
0 引 言
近些年來,社會的進(jìn)步推動(dòng)了電網(wǎng)的規(guī)模化建設(shè)和發(fā)展。在大運(yùn)行體系的建設(shè)下,電網(wǎng)調(diào)度技術(shù)的應(yīng)用中更需要有效滿足數(shù)據(jù)采集以及數(shù)據(jù)交換的需求[1]。就S地區(qū)供電公司調(diào)度數(shù)據(jù)網(wǎng)的建設(shè)發(fā)展中,更是結(jié)合網(wǎng)絡(luò)上的方式實(shí)現(xiàn)數(shù)據(jù)的傳送。當(dāng)前變電站的運(yùn)作過程應(yīng)用的是無人值守模式,而調(diào)度數(shù)據(jù)網(wǎng)通道時(shí),一旦發(fā)生故障將難以查找到故障點(diǎn),以至于故障難以得到及時(shí)修復(fù),使得廠站出現(xiàn)監(jiān)視不靈的狀態(tài)[2]。在對電網(wǎng)穩(wěn)定運(yùn)行的保障下,更要結(jié)合現(xiàn)代化先進(jìn)技術(shù),做好調(diào)度數(shù)據(jù)網(wǎng)通道故障的有效處理。
電力調(diào)度數(shù)據(jù)網(wǎng)作為生產(chǎn)控制業(yè)務(wù)的一種專用網(wǎng)絡(luò),實(shí)現(xiàn)了各級調(diào)控中心間數(shù)據(jù)的傳輸,并實(shí)現(xiàn)了基礎(chǔ)設(shè)施信息傳遞。在電網(wǎng)建設(shè)階段,調(diào)度數(shù)據(jù)網(wǎng)的規(guī)?;l(fā)展,保證了電網(wǎng)的安全可靠性運(yùn)行。伴隨著當(dāng)前微電子技術(shù)的不斷發(fā)展成熟,網(wǎng)絡(luò)設(shè)備更是有著多樣化的體系架構(gòu),結(jié)合行業(yè)的發(fā)展特點(diǎn),可實(shí)現(xiàn)通用網(wǎng)絡(luò)設(shè)備故障的及時(shí)診斷[3]。
本文的研究主要是在廠站一次接線圖上對腳本程序進(jìn)行開發(fā)設(shè)計(jì),并結(jié)合腳本程序?qū)崿F(xiàn)ping命令功能,在通信故障判斷過程中,提高了故障診斷的準(zhǔn)確性。
1 調(diào)度數(shù)據(jù)網(wǎng)通道圖形界面的設(shè)計(jì)
對于調(diào)度數(shù)據(jù)網(wǎng)通道圖形界面的設(shè)計(jì)而言,主要是結(jié)合ping命令,在主調(diào)前置服務(wù)器上實(shí)現(xiàn)操作。通過將腳本程序錄入前置服務(wù)器,并結(jié)合工作站點(diǎn)的形式,做好遠(yuǎn)程調(diào)用的工作。在一次接線圖上繪制標(biāo)志調(diào)用按鈕[4]。以S地區(qū)某一變電站作為例,通過打開該變電站廠站的接線圖編輯窗,結(jié)合繪圖工具,繪制標(biāo)志調(diào)用按鈕,點(diǎn)擊標(biāo)志調(diào)用的右鍵,選擇屬性,結(jié)合彈出的對話框,選擇進(jìn)程調(diào)用,如圖1所示,將“.RE xtl_fes3:/hpme/d5000/hebei/ping.sh”錄入,保存之后,退出。
2 腳本程序設(shè)計(jì)
廠站數(shù)據(jù)的分析過程往往是對網(wǎng)絡(luò)是否處于正常情況的判斷的過程。第一種情況是對站端業(yè)務(wù)地址不通情況的判斷;第二種則是對業(yè)務(wù)網(wǎng)不通狀況的判斷。在此結(jié)合程序中的一種IP地址,應(yīng)用ping指令結(jié)果,對故障的原因進(jìn)行判斷[5]。在S地區(qū)某一變電站的業(yè)務(wù)地址分析中,其地址主要是12.100.100.1,對于其中路由器側(cè)網(wǎng)關(guān)而言,主要是12.100.100.254。在業(yè)務(wù)地址處于不通的狀況,其網(wǎng)關(guān)處于較通的狀況下,做好站端問題有效性判斷[6]。一旦網(wǎng)關(guān)處于不通的狀態(tài),其業(yè)務(wù)地址也處于不通的狀況。在通信網(wǎng)絡(luò)設(shè)備配置問題的判斷過程中,結(jié)合廠站數(shù)據(jù)的正常運(yùn)行情況,做好程序主體性的設(shè)計(jì)和應(yīng)用[3]?;贚inux系統(tǒng)中的一種命令,將文本輸出,腳本程序的設(shè)計(jì)過程如下:
[addr_a=$(echo 12.100.100.1)
addr_b=$(echo 12.100.100.254)
′ping?cl ?w2 $addr_a>dev/null′
Ret_a=$
′ping?cl ?w2 $addr_a>dev/null′
Ret_b=$
Case $ret_a in
?2147483648)ok_a=1
;;
*)ok_a=0
;;
Esac
Case $ret_b in
0)ok_b=1
;;
*)ok_b=0
;;

3 故障的診斷和測試
圖形界面的設(shè)計(jì)中,主要實(shí)現(xiàn)D5000系統(tǒng)中的一種調(diào)度數(shù)據(jù)網(wǎng)通道故障,在功能性的判斷過程中,結(jié)合故障判斷進(jìn)行功能測試[7]。就S變電站的一次接線圖按鈕而言,通過點(diǎn)擊ping按鈕,將窗口上傳,如圖2所示。
在S變電站一次接線圖的按鈕實(shí)現(xiàn)中,調(diào)度數(shù)據(jù)網(wǎng)遠(yuǎn)動(dòng)業(yè)務(wù)的中斷如圖3所示。
S變電站網(wǎng)關(guān)中斷的彈窗如圖4所示。
4 應(yīng)用效果分析
對于D5000系統(tǒng)調(diào)度數(shù)據(jù)網(wǎng)通道故障判斷過程,在此將本文變電站與S地區(qū)的其他A變電站和B變電站進(jìn)行對比[8],其故障排查的時(shí)間如表1所示。相對而言,本文的故障排除方法,可以有效縮短故障的用時(shí),同時(shí)也提高了故障排除的準(zhǔn)確性提高。
