摘 要:針對變電站綜合自動化改造過程中設備停電時間與施工時間、人力安排之間的矛盾問題,提出一種新型的改造策略——原屏改造。闡述了新型原屏改造策略的含義特點、風險評估管控與具體實施步驟等內容,并以某110 kV變電站為例,介紹了原屏改造策略的試點過程及成效。實例結果表明,原屏改造技改策略能顯著減少停電改造時間,降低改造成本,有效提升二次設備改造效率。
關鍵詞:變電站;原屏改造;綜合自動化;供電可靠性;改造時間

Abstract: To solve the contradiction between power outage time and equipment reconstruction time in the process of substation synthetic automation reconstruction engineering, this paper put forward a new strategy of reconstruction called original cabinet reconstruction (OCR). This paper introduced the characteristics, risks assessment and implementation steps of the new OCR strategy. Moreover, a certain 11 0 kV substation was taken as an example for pilot project, and the pilot process and results were analyzed. The living example results show that the total elapsed time of the project is reduced and the improvement cost is reduced, which can effectively promote the efficiency of secondary equipment transformation.
Key words: substation; original cabinet reconstruction; protection and synthetic automation; power supply reliability; reconstruction time
