摘要


近年來,由於精密電子儀器與非線性負載的增加,使得電力暫態信號現象廣泛的受到重視。傳統小波轉換最常成用在小波分析電力擾動,有別於傅立葉轉換,小波轉換具有時域和頻域多重解析的能力。小波轉換的偵測能力會因雜訊的影響而大幅降低,因此利用抑制雜訊演算法,調整抑制雜訊之門檻值,此門檻值會依據背景雜訊來自動調整,將難以辨別是否為暫態信號的雜訊因為調整門檻值變能偵測是否在雜訊中含有暫態現象的發生。本論文使用硬體架構此離散小波轉換與抑制雜訊演算法,使用Alter公司提供的集成環境QuartusⅡ來實現電力品質暫態事件偵測器,並以ModelSim結果與MATLAB相互比對,證明本論文所設計之硬體架構無誤。
