【摘要】：繼電保護系統(tǒng)是電力系統(tǒng)的重要組成部分,對保證電力系統(tǒng)安全穩(wěn)定運行和系統(tǒng)中重要組件的正常工作有重要意義。在繼電保護系統(tǒng)的運行過程中會出現(xiàn)一些缺陷,使系統(tǒng)不能有效工作,有些甚至直接影響到電力系統(tǒng)的可靠運行,快速可靠的消除這些缺陷,是繼電保護日常維護中的重要任務(wù)之一。 本文首先對繼電保護系統(tǒng)的組成進行了簡要介紹,其次對消缺過程進行詳細分析,通過對典型缺陷的各個屬性：故障名稱、故障現(xiàn)象、故障原因分析、安全注意事項以及處理步驟之間關(guān)系的分析和梳理,根據(jù)相互之間的依賴關(guān)系搭建數(shù)據(jù)模型,作為專家系統(tǒng)的數(shù)據(jù)源。 其次在傳統(tǒng)消缺工作的基礎(chǔ)上引入層次分析法,建立了基于層次分析法的優(yōu)化模型。該模型針對消缺工作的特點,以消缺最優(yōu)化為目標、消缺中需要考慮的各因素為準則、待排查故障部位為方案,最后得到各可能發(fā)生故障部位的綜合權(quán)重排序,即為消缺排查的最優(yōu)排序。該方法將傳統(tǒng)消缺過程的隨機逐個排查轉(zhuǎn)變?yōu)榘凑湛紤]各影響因素的優(yōu)化結(jié)果排查,提高了消缺效率。 最后根據(jù)數(shù)據(jù)模型以及優(yōu)化模型開發(fā)出一套繼電保護專家系統(tǒng),實現(xiàn)該優(yōu)化方法的可視化操作和快速計算,根據(jù)數(shù)據(jù)庫中的數(shù)據(jù)直接生成消缺的最優(yōu)結(jié)果,有利于該方法的使用和推廣。
[Abstract]:Relay protection system is an important part of power system. It is of great significance to ensure the safe and stable operation of power system and the normal operation of important components in the system. During the operation of the relay protection system, there will be some defects, which will make the system work effectively, and some will directly affect the reliable operation of the power system, and eliminate these defects quickly and reliably. Is the relay protection in the daily maintenance of an important Ren Wuzhi. In this paper, the composition of relay protection system is introduced briefly, and then the process of eliminating defects is analyzed in detail. Through the analysis of each attribute of typical defect: fault name, fault phenomenon, fault cause, Based on the analysis and combing of the relationship between the security matters and the processing steps, the data model is built to be the data source of the expert system. Secondly, on the basis of the traditional work of eliminating defects, the analytic hierarchy process (AHP) is introduced, and the optimization model based on AHP (Analytic hierarchy process) is established. According to the characteristics of the work, the model takes the optimization of the elimination as the goal, the factors to be considered in the elimination as the criterion, and the fault location to be checked as the scheme. Finally, the comprehensive weight ranking of the possible fault sites is obtained. In other words, it is the optimal order of eliminating deficiency and checking. In this method, the random search of the traditional elimination process is changed to the optimization result considering various factors, and the efficiency of elimination is improved. Finally, according to the data model and optimization model, a relay protection expert system is developed, which realizes the visual operation and fast calculation of the optimization method, and directly generates the optimal result of elimination according to the data in the database. It is beneficial to the use and popularization of this method.
