This paper is about the study on the debugging and maintenance of substation automation system the author analyzes and compares the present debugging interface of microprocessor - based protection relays through summarizing the debugging and maintenance of routine substation automation system , indicates the advantage of software debugging interface based on the pc in allusion to the characteristics of the distributed substation automation system , the author presents the design idea of programming the debugging software for the intelligent devices , the monitoring station and the communication network based on the object - oriented programmable technology this method may simplify the workload of debugging and maintenance of substation automation system greatly , shorten the time limit for building and debugging of substation automation system and improve the security and the stability of system , therefore it is of great useful value 作者通過歸納總結(jié)常規(guī)變電站自動化系統(tǒng)的調(diào)試方法和維護手段,分析比較了現(xiàn)有的微機保護調(diào)試界面,指出了基于pc機的軟件化調(diào)試界面的優(yōu)越性。針對分層分布式變電站自動化系統(tǒng)的特點,提出了利用面向?qū)ο缶幊碳夹g(shù),編制間隔層智能裝置和變電站層監(jiān)控系統(tǒng)及通訊網(wǎng)絡(luò)層報文監(jiān)視的智能化調(diào)試軟件的設(shè)計思想。該方法可大大簡化變電站自動化系統(tǒng)的調(diào)試和維護工作量,進一步縮短變電站自動化系統(tǒng)的安裝調(diào)試工期,提高系統(tǒng)運行的安全性與穩(wěn)定性,具有很大的實用價值。
