     全(quan)面(mian)分析我國當前電氣化(hua)鐵道牽(qian)引供(gong)(gong)電技術(shu)、接(jie)觸網特點和安(an)(an)全(quan)操作(zuo)規(gui)程(cheng)的(de)基礎上，通過計算機仿(fang)真模(mo)擬(ni)電氣化(hua)鐵道牽(qian)引供(gong)(gong)電所涉及的(de)供(gong)(gong)電過程(cheng)、電氣主結線(xian)、相關高壓配電裝置以及安(an)(an)全(quan)操作(zuo)規(gui)程(cheng)。系(xi)統(tong)由(you)兩部分組成：軟件系(xi)統(tong)模(mo)擬(ni)仿(fang)真2個(ge)(ge)(ge)牽(qian)引變(bian)電所（1#、2#）、1個(ge)(ge)(ge)開閉所（主供(gong)(gong)車站(zhan)2#側線(xian)）、2個(ge)(ge)(ge)分區所，供(gong)(gong)電方式采用直供(gong)(gong)加(jia)回流線(xian)方式，形成一套完整的(de)牽(qian)引供(gong)(gong)電（正常或(huo)者故障狀(zhuang)(zhuang)態）以及實現電源側、母聯(lian)側、饋出側聯(lian)鎖(suo)；硬件模(mo)擬(ni)系(xi)統(tong)（接(jie)觸網供(gong)(gong)電控制(zhi)箱）向各(ge)段接(jie)觸網供(gong)(gong)電，并通過串口(kou)接(jie)收來自軟件界面(mian)各(ge)隔離(li)開關和斷路器(qi)的(de)操作(zuo)信號實現各(ge)段接(jie)觸網供(gong)(gong)電狀(zhuang)(zhuang)態的(de)變(bian)換(huan)。

1、接觸網沙盤模型

      沙盤(pan)設(she)有1個(ge)既有鐵路(lu)中(zhong)間(jian)站、或N個(ge)既有線(xian)(xian)(xian)(xian)中(zhong)間(jian)車站、雙線(xian)(xian)(xian)(xian)區間(jian)、綜合橋梁、隧(sui)道(dao)、涵洞，全(quan)整的圓曲線(xian)(xian)(xian)(xian)、平交道(dao)口、設(she)典(dian)型(xing)道(dao)岔自動(dong)(dong)控(kong)(kong)制；2個(ge)牽引變電(dian)(dian)所(suo)(suo)、2個(ge)分區亭、1個(ge)開(kai)閉(bi)所(suo)(suo)（內部結構(gou)清(qing)楚，原(yuan)理準確，通電(dian)(dian)演示）與(yu)1個(ge)AT所(suo)(suo)(靜態模型(xing))。既有線(xian)(xian)(xian)(xian)接(jie)(jie)觸(chu)網(wang)（可通電(dian)(dian)）采用(yong)半補(bu)償懸(xuan)掛裝(zhuang)置(zhi)與(yu)全(quan)補(bu)償懸(xuan)掛裝(zhuang)置(zhi)，四股道(dao)車站采用(yong)橫跨（兩(liang)個(ge)軟橫跨和兩(liang)個(ge)硬橫跨）。線(xian)(xian)(xian)(xian)路(lu)上設(she)有分段絕緣(yuan)器、錨(mao)段關節(jie)、中(zhong)心錨(mao)節(jie)、饋(kui)電(dian)(dian)線(xian)(xian)(xian)(xian)、電(dian)(dian)連接(jie)(jie)器、回流線(xian)(xian)(xian)(xian)等設(she)備及各(ge)種(zhong)線(xian)(xian)(xian)(xian)路(lu)、信(xin)號標(biao)志并可通電(dian)(dian)演示及控(kong)(kong)制，信(xin)號設(she)自動(dong)(dong)閉(bi)塞。接(jie)(jie)觸(chu)線(xian)(xian)(xian)(xian)、鋼軌均為銅制。配遙(yao)控(kong)(kong)電(dian)(dian)力機(ji)車兩(liang)臺運行。整體形象逼真，結構(gou)清(qing)楚，制作精美，采用(yong)計算(suan)機(ji)控(kong)(kong)制系統(tong) ，CRH2型(xing)動(dong)(dong)車組從接(jie)(jie)觸(chu)網(wang)受(shou)電(dian)(dian)運行。

3、牽引變電(dian)模型

    沙盤設置2個(ge)牽(qian)引變(bian)電所（1#、2#）、1個(ge)開(kai)閉所（主供車站2#側線(xian)）、2個(ge)分(fen)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(gong)電(dian)系統操(cao)作臺

       系統(tong)實現牽引變電所、開閉(bi)所、分(fen)區所的計算機(ji)(ji)綜合控制(zhi)(zhi)功能。利用計算機(ji)(ji)控制(zhi)(zhi)軟件實現對牽引供(gong)(gong)電的控制(zhi)(zhi)。真實再現牽引供(gong)(gong)電在不同(tong)運行方式和運行狀態下控制(zhi)(zhi)及操作功能，通(tong)過(guo)軟件界面(mian)實現真實供(gong)(gong)電系統(tong)的調度仿真。
