中文摘要 | 絕緣油中溶解氣體分析的故障診斷法已發展與推廣多年。此法可及早發 現變壓器內部的故障現象,效果頗佳。但是各項資訊尚未能充分整合運用,因此 均依賴有經驗的專家進行綜合研判,使得此項技術較偏主觀意見。為此乃研究「變 壓器故障診斷專家系統」。本研究成功地發展出專家系統雛形。本系統利用模糊 邏輯的觀念,解決了傳統數碼診斷法的限制,其診斷能力並經實例驗證,成效甚 佳。 |
英文摘要 | The faults diagnosis for oil-immersed transformers using dissolvedgas analysis has been developed and spreaded for many years. Thistechnology is effective for detecting incipient faults inside transformers.However, the lack of sufficient integration of related data caused toemany expert's subjective opinions in the existing diagnosis process. Thismotivates the study of expert system for transformer faults diagnosis, Inthis study, a prototype expert system is developed successfully. The fuzzylogic is applied to deal with imprecision in decision making of ratiomethods. This system's ability of diagnosis is proved to be effective bytesting practical examples. |
