摘 要:針對電力調度無法直接獲取變電站歷史告警記錄的問題,對DL 476協議進行了研究,并設計了一種基于DL 476協議的電力調度遠方歷史記錄查詢系統。給出了系統總體架構、查詢流程及DL 476報文格式設計步驟,該系統采用分頁查詢模式,經在重慶110 kV 新一代銀盆變中現場應用,應用結果表明,該系統可有效實現在調度主站查詢遠方變電站內的歷史告警信息,便于排查故障,避免了人工進站查詢的步驟,提高了工作執行效率。

Abstract: Aiming at the problem that the power dispatching cannot obtain the historical alarm record of the substation directly, this paper carried out research on DL 476 protocol and designed a kind of power dispatching remote history record query system. This paper gave the overall architecture of the system, the query procedure and DL 476 message format design procedure. This system adopted the paging query mode. After the field application in the new generation Yinpeng transformer of Chongqing 110 kV substation, the result shows that this system could effectively realize the history alarm messages query from the dispatching primary station in remote substation, which is convenient for the troubleshoot, avoids the procedure of manual work get-in query and improves the working execution efficiency.
Key words: DL 476 protocol; paging query; alarm upload; intelligent dispatching
