摘 要：針對(duì)電力調(diào)度無(wú)法直接獲取變電站歷史告警記錄的問(wèn)題，對(duì)DL 476協(xié)議進(jìn)行了研究，并設(shè)計(jì)了一種基于DL 476協(xié)議的電力調(diào)度遠(yuǎn)方歷史記錄查詢系統(tǒng)。給出了系統(tǒng)總體架構(gòu)、查詢流程及DL 476報(bào)文格式設(shè)計(jì)步驟，該系統(tǒng)采用分頁(yè)查詢模式，經(jīng)在重慶110 kV 新一代銀盆變中現(xiàn)場(chǎng)應(yīng)用，應(yīng)用結(jié)果表明，該系統(tǒng)可有效實(shí)現(xiàn)在調(diào)度主站查詢遠(yuǎn)方變電站內(nèi)的歷史告警信息，便于排查故障，避免了人工進(jìn)站查詢的步驟，提高了工作執(zhí)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
