     全(quan)面分析我國當前電(dian)(dian)(dian)氣化鐵道牽(qian)(qian)引供(gong)電(dian)(dian)(dian)技(ji)術(shu)、接觸網(wang)特點和安全(quan)操(cao)作規(gui)程的基(ji)礎(chu)上(shang)，通(tong)過(guo)計(ji)算機仿真模(mo)擬(ni)電(dian)(dian)(dian)氣化鐵道牽(qian)(qian)引供(gong)電(dian)(dian)(dian)所涉及(ji)的供(gong)電(dian)(dian)(dian)過(guo)程、電(dian)(dian)(dian)氣主結線(xian)、相關(guan)高壓配電(dian)(dian)(dian)裝置以及(ji)安全(quan)操(cao)作規(gui)程。系統(tong)由兩部(bu)分組成：軟(ruan)件系統(tong)模(mo)擬(ni)仿真2個(ge)牽(qian)(qian)引變電(dian)(dian)(dian)所（1#、2#）、1個(ge)開(kai)閉所（主供(gong)車(che)站(zhan)2#側線(xian)）、2個(ge)分區所，供(gong)電(dian)(dian)(dian)方(fang)式采(cai)用(yong)直供(gong)加(jia)回流(liu)線(xian)方(fang)式，形(xing)成一套完整的牽(qian)(qian)引供(gong)電(dian)(dian)(dian)（正常或者故障狀態(tai)）以及(ji)實現(xian)(xian)電(dian)(dian)(dian)源側、母(mu)聯側、饋(kui)出側聯鎖；硬件模(mo)擬(ni)系統(tong)（接觸網(wang)供(gong)電(dian)(dian)(dian)控制箱(xiang)）向各(ge)段(duan)(duan)接觸網(wang)供(gong)電(dian)(dian)(dian)，并通(tong)過(guo)串口接收來自軟(ruan)件界面各(ge)隔離(li)開(kai)關(guan)和斷路器的操(cao)作信(xin)號(hao)實現(xian)(xian)各(ge)段(duan)(duan)接觸網(wang)供(gong)電(dian)(dian)(dian)狀態(tai)的變換。

1、接觸(chu)網沙盤模(mo)型

      沙盤設(she)有(you)1個(ge)(ge)既有(you)鐵路中(zhong)間站(zhan)、或N個(ge)(ge)既有(you)線(xian)中(zhong)間車站(zhan)、雙(shuang)線(xian)區間、綜(zong)合橋梁、隧道、涵洞(dong)，全整的圓曲(qu)線(xian)、平交道口、設(she)典(dian)型道岔自動控(kong)制；2個(ge)(ge)牽引變電所(suo)、2個(ge)(ge)分區亭、1個(ge)(ge)開閉(bi)所(suo)（內部(bu)結(jie)構(gou)清楚，原理準(zhun)確，通電演示）與(yu)(yu)1個(ge)(ge)AT所(suo)(靜態模型)。既有(you)線(xian)接(jie)觸網(wang)（可通電）采(cai)用(yong)半補(bu)償懸掛裝置與(yu)(yu)全補(bu)償懸掛裝置，四股道車站(zhan)采(cai)用(yong)橫(heng)(heng)跨(kua)（兩個(ge)(ge)軟橫(heng)(heng)跨(kua)和兩個(ge)(ge)硬橫(heng)(heng)跨(kua)）。線(xian)路上設(she)有(you)分段絕(jue)緣器、錨段關節、中(zhong)心錨節、饋電線(xian)、電連接(jie)器、回流線(xian)等設(she)備及(ji)各種(zhong)線(xian)路、信(xin)號標志并可通電演示及(ji)控(kong)制，信(xin)號設(she)自動閉(bi)塞(sai)。接(jie)觸線(xian)、鋼軌均(jun)為(wei)銅制。配遙控(kong)電力機車兩臺運(yun)(yun)行(xing)。整體形象逼真，結(jie)構(gou)清楚，制作精美，采(cai)用(yong)計算(suan)機控(kong)制系統 ，CRH2型動車組從接(jie)觸網(wang)受電運(yun)(yun)行(xing)。

3、牽引變(bian)電模型

    沙盤設置2個牽引(yin)變電所（1#、2#）、1個開(kai)閉所（主供車(che)站2#側線）、2個分區所；采用彩色有機玻璃雕刻技術，來模擬牽引變電所的房屋。

4、微機聯鎖及牽引供電系統(tong)操作臺(tai)

       系(xi)統實現牽引變電(dian)所(suo)(suo)、開閉所(suo)(suo)、分區(qu)所(suo)(suo)的計(ji)(ji)算機綜(zong)合控(kong)制(zhi)功(gong)(gong)能(neng)。利(li)用計(ji)(ji)算機控(kong)制(zhi)軟(ruan)件實現對牽引供(gong)電(dian)的控(kong)制(zhi)。真實再現牽引供(gong)電(dian)在不同運行方式和運行狀態(tai)下控(kong)制(zhi)及操(cao)作功(gong)(gong)能(neng)，通(tong)過軟(ruan)件界面實現真實供(gong)電(dian)系(xi)統的調度仿真。
