3、牽引(yin)變(bian)電模型

    沙盤設置2個牽引變電所(suo)（1#、2#）、1個開閉所(suo)（主供車站2#側線(xian)）、2個分區所(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(lian)鎖(suo)及牽引供電系統操(cao)作臺

       系統(tong)實(shi)現(xian)牽引(yin)變電所、開閉所、分(fen)區所的計算(suan)機(ji)綜合(he)控(kong)(kong)制(zhi)(zhi)功(gong)能(neng)。利用計算(suan)機(ji)控(kong)(kong)制(zhi)(zhi)軟件(jian)實(shi)現(xian)對(dui)牽引(yin)供(gong)電的控(kong)(kong)制(zhi)(zhi)。真實(shi)再現(xian)牽引(yin)供(gong)電在(zai)不同運行方式和運行狀態下控(kong)(kong)制(zhi)(zhi)及操作功(gong)能(neng)，通(tong)過軟件(jian)界(jie)面實(shi)現(xian)真實(shi)供(gong)電系統(tong)的調度仿(fang)真。
