3、牽引變(bian)電模型

    沙盤設置2個牽引變(bian)電所(suo)（1#、2#）、1個開閉所(suo)（主供車站2#側線(xian)）、2個分區(qu)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(wei)機聯鎖(suo)及牽引供(gong)電(dian)系統操作(zuo)臺

       系統實現牽引變電(dian)所、開(kai)閉所、分區所的計(ji)(ji)算(suan)(suan)機綜合(he)控(kong)制功(gong)能。利用計(ji)(ji)算(suan)(suan)機控(kong)制軟(ruan)件實現對(dui)牽引供(gong)(gong)電(dian)的控(kong)制。真(zhen)(zhen)實再現牽引供(gong)(gong)電(dian)在不同運行方式和運行狀態下控(kong)制及(ji)操作功(gong)能，通(tong)過軟(ruan)件界面實現真(zhen)(zhen)實供(gong)(gong)電(dian)系統的調度(du)仿真(zhen)(zhen)。
