     全(quan)面(mian)分(fen)析(xi)我國當前電(dian)(dian)氣化鐵(tie)(tie)道(dao)牽(qian)(qian)引(yin)供(gong)(gong)電(dian)(dian)技術、接觸網特點和安全(quan)操作(zuo)(zuo)規程(cheng)的(de)(de)基礎上，通(tong)過(guo)計(ji)算機仿真模擬電(dian)(dian)氣化鐵(tie)(tie)道(dao)牽(qian)(qian)引(yin)供(gong)(gong)電(dian)(dian)所(suo)(suo)涉及(ji)的(de)(de)供(gong)(gong)電(dian)(dian)過(guo)程(cheng)、電(dian)(dian)氣主結線(xian)、相關高(gao)壓(ya)配電(dian)(dian)裝(zhuang)置以及(ji)安全(quan)操作(zuo)(zuo)規程(cheng)。系統由兩部分(fen)組(zu)成：軟件(jian)系統模擬仿真2個(ge)(ge)牽(qian)(qian)引(yin)變(bian)(bian)電(dian)(dian)所(suo)(suo)（1#、2#）、1個(ge)(ge)開閉所(suo)(suo)（主供(gong)(gong)車站2#側線(xian)）、2個(ge)(ge)分(fen)區所(suo)(suo)，供(gong)(gong)電(dian)(dian)方式采用直供(gong)(gong)加(jia)回流(liu)線(xian)方式，形成一(yi)套完整的(de)(de)牽(qian)(qian)引(yin)供(gong)(gong)電(dian)(dian)（正常或者故障狀(zhuang)態）以及(ji)實現電(dian)(dian)源側、母聯(lian)側、饋出(chu)側聯(lian)鎖；硬件(jian)模擬系統（接觸網供(gong)(gong)電(dian)(dian)控(kong)制(zhi)箱）向各段接觸網供(gong)(gong)電(dian)(dian)，并通(tong)過(guo)串口接收來自軟件(jian)界(jie)面(mian)各隔離開關和斷路器的(de)(de)操作(zuo)(zuo)信號(hao)實現各段接觸網供(gong)(gong)電(dian)(dian)狀(zhuang)態的(de)(de)變(bian)(bian)換。

1、接觸網沙盤模型

      沙盤設(she)有(you)1個(ge)(ge)既(ji)有(you)鐵路(lu)中(zhong)間站(zhan)、或N個(ge)(ge)既(ji)有(you)線(xian)中(zhong)間車(che)站(zhan)、雙線(xian)區(qu)間、綜合橋梁、隧(sui)道、涵洞，全整的(de)圓(yuan)曲(qu)線(xian)、平交道口、設(she)典型道岔自動控制；2個(ge)(ge)牽引變電(dian)(dian)(dian)所、2個(ge)(ge)分區(qu)亭、1個(ge)(ge)開閉(bi)所（內部(bu)結構清楚(chu)，原理準確，通(tong)(tong)電(dian)(dian)(dian)演示）與1個(ge)(ge)AT所(靜態模型)。既(ji)有(you)線(xian)接觸網(wang)（可通(tong)(tong)電(dian)(dian)(dian)）采用半補償(chang)懸(xuan)掛(gua)裝置(zhi)與全補償(chang)懸(xuan)掛(gua)裝置(zhi)，四股道車(che)站(zhan)采用橫跨（兩個(ge)(ge)軟橫跨和兩個(ge)(ge)硬橫跨）。線(xian)路(lu)上設(she)有(you)分段絕緣器、錨(mao)段關節(jie)、中(zhong)心錨(mao)節(jie)、饋電(dian)(dian)(dian)線(xian)、電(dian)(dian)(dian)連接器、回流(liu)線(xian)等(deng)設(she)備及各(ge)種線(xian)路(lu)、信號標志(zhi)并可通(tong)(tong)電(dian)(dian)(dian)演示及控制，信號設(she)自動閉(bi)塞。接觸線(xian)、鋼軌均為銅制。配遙控電(dian)(dian)(dian)力機車(che)兩臺運行。整體(ti)形象逼真(zhen)，結構清楚(chu)，制作精美(mei)，采用計(ji)算機控制系統 ，CRH2型動車(che)組從接觸網(wang)受電(dian)(dian)(dian)運行。

3、牽引變電模型

    沙盤設置2個(ge)牽(qian)引變電(dian)所(suo)（1#、2#）、1個(ge)開閉所(suo)（主(zhu)供車站2#側線）、2個(ge)分區所(suo)；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(yin)供(gong)電系統操作臺

       系統實現(xian)牽(qian)(qian)引(yin)變電(dian)所、開閉所、分區所的(de)(de)計算機綜合控制(zhi)功能。利用計算機控制(zhi)軟件實現(xian)對牽(qian)(qian)引(yin)供電(dian)的(de)(de)控制(zhi)。真實再現(xian)牽(qian)(qian)引(yin)供電(dian)在不(bu)同運(yun)行(xing)方式和運(yun)行(xing)狀態(tai)下控制(zhi)及操作功能，通過軟件界(jie)面實現(xian)真實供電(dian)系統的(de)(de)調度(du)仿真。
