運行人員控制允許執(zhí)行以下功效：控制操作，CRT顯示畫面選擇，報警確認，數(shù)據(jù)錄入，命令日志，改變限值和變電站測點投用/停用。SCADA系統(tǒng)也提供顯示和打印，數(shù)據(jù)錄入、控制點選擇和報警功效。第14頁TranslationSkill被動句翻譯1、譯為被動句 為保持譯文準確性，通常可保留被動語氣。慣用“被、由、為、受、靠……”等詞表示。

Thekeyboardandspecial-functionpushbuttonsareusedbytheoperatorforthedisplayfunction。 鍵盤和特殊功效按鈕被操作員用于顯示。第15頁TranslationSkill被動句翻譯2、譯為漢語主動句 一些情況下，用被動翻譯譯句語序不好處理，可譯為主動句，即采取反譯法。
