- 2 . design the scheme of expert system for transformer fault diagnosis based on dga and rough set theory ieee considers dissolved gas analysis ( dga ) is the most efficient method to examine the interior fault of transformer
基于氣相色譜分析和粗糙集理論的電力變壓器故障診斷專家系統(tǒng)方案設(shè)計(jì)變壓器內(nèi)部故障的檢測(cè)有多種手段， ieee認(rèn)為對(duì)變壓器內(nèi)部故障早期診斷最有效的方法是油中氣體色譜分析法。 - Combining ann with dissolved gas analysis ( dga ) that is a typical method in transformer diagnosis , transformer fault diagnosis system with friendly interface and excellent capability is finished by java . besides , the method of selecting networks parameter is discussed detailedly , and the influence of different parameters on diagnosis results is analyzed
將變壓器診斷中典型的油中氣體分析法和神經(jīng)網(wǎng)絡(luò)方法相結(jié)合，采用java語言開發(fā)出界面友好、性能優(yōu)秀的變壓器故障診斷系統(tǒng)；此外，文中還詳細(xì)探討了網(wǎng)絡(luò)各結(jié)構(gòu)參數(shù)的選擇方法，并且就變壓器這一實(shí)際診斷系統(tǒng)，分析了不同結(jié)構(gòu)參數(shù)對(duì)系統(tǒng)誤差的影響。 - In accordance with the technological difficulties encountered in the process of insulation supervision based on the dissolved gases analysis ( dga ) , several kinds of model and method are presented to improve the reliability and precision of fault diagnosis of the power transformer . main research content includes : by deeply studying the common transformer faults diagnosing methods , such as three - ratio methods and improved electrical committee agreements , several shortcomings such as uncertainness judgment when the fault reasons , phenomenon and principles come out together while can not consistent to each other etc . for this reason , the old methods can not fully meet the need to engineering practical application . considering fuzzy relationship matrix can fully represents the causality between fault symptoms and fault types , when diagnosing complex equipments with multiple symptoms and fault causes such as power transformer , a synthetic fuzzy diagnosing model is firstly proposed to diagnose transformer ' s insulation faults based on dga in this paper
本文針對(duì)應(yīng)用油中溶解氣體分析方法進(jìn)行變壓器絕緣監(jiān)督時(shí)所遇到的主要技術(shù)難點(diǎn)，提出了提高變壓器故障診斷的準(zhǔn)確性、可靠性的幾種模診斷方法，主要研究內(nèi)容有：通過對(duì)判斷變壓器故障常用的三比值法和改良電協(xié)研法的深入分析，其診斷準(zhǔn)確率較高，但對(duì)故障原因、故障現(xiàn)象和故障機(jī)理間同時(shí)存在不確定性和模糊性的變壓器等電氣設(shè)備的故障診斷，難于滿足工程應(yīng)用的需要；在處理變壓器等結(jié)構(gòu)復(fù)雜設(shè)備的多癥狀、多原因故障診斷時(shí)，模糊關(guān)系矩陣可以全面反映這種癥狀與故障類型間的因果關(guān)系，進(jìn)而提出了變壓器故障診斷的模糊綜合診斷模型；同時(shí)作者還深入分析了模糊算子的特性；針對(duì)常用的模糊評(píng)判結(jié)果的模糊集的集化方法的不足性，提出了將模糊綜合診斷與模糊規(guī)則推理結(jié)合起來進(jìn)行故障診斷的方法，能達(dá)到較好的效果。 - Dissolved gas analysis ( dga ) is one of the mainly technology methods to diagnose the internal malfunction in transformer . by request of dl / t722 - 2000 , < guide to the analysis and the diagnosis of gases dissolved in transformer oil > , the component of h _ 2 , c _ 2h _ 2 , c _ 2h _ 4 , c _ 2h _ 6 , ch _ 4 , co and co _ 2 is used to judge and analyze the internal malfunction in transformer
本系統(tǒng)首先接收氣相色譜儀發(fā)送的數(shù)據(jù)信息,并對(duì)這些數(shù)據(jù)進(jìn)行處理與分析,計(jì)算出譜圖數(shù)據(jù)的波峰高度、波峰面積、波峰起始點(diǎn)、基線等值,在此基礎(chǔ)上依據(jù)定量分析及故障診斷原理對(duì)變壓器進(jìn)行診斷,得出結(jié)論。
