摘 要:當變電站端遠動裝置主通道與備用通道之間在配合上出現問題時,變電站端遠動裝置會向調度端監控系統上送報文信息,影響調度監控人員對變電站的正常監視?;谀匙冸娬疽黄?20 kV線路跳閘事故時的調度端報文,對報文中存在的備通道補現象進行原因分析,確定為設備硬件原因導致這一現象,經更換遠動裝置通信板插件后,問題得以解決,為同一類型廠站端自動化系統缺陷處理提供參考。
關鍵詞:變電站監控系統;線路跳閘;遠動裝置;主通道;備用通道;報文

Abstract: When there is a problem in the coordination between the main channel and the backup channel of the substation terminal remote control device, the substation terminal remote control device will send message information to the dispatching terminal monitoring system, so as to affect the regular substation monitoring of dispatching monitoring personnel. Based on the dispatching terminal message of a 220 kV line trip accident, this paper analyzed the causes of the alternate channel filling phenomenon in the message, making sure that it was the hardware of the device. After the remote control device changed, the problem could be solved, which provides the reference for the same type of factory station automation system defect treatment.
Key words: substation monitoring system; line tripping; remote control device; main channel; alternate channel; message
