隨著科技的發展，電力電子設備日漸益增，使得電力品質逐漸受到重視。其中，諧波問題是重要的干擾源之一，其影響了電力電子設備的運轉，影響範圍可大可小，對於一般家庭用電戶而言，或許只造成用電設備短期電力中斷，但對於大型設備可能會引發故障，甚至帶來經濟效應的問題，因此，電力品質的檢測是一項值得探討的議題。
為了要擁有良好的電力品質，必須先將電力系統進行諧波分析，進而提出改善策略。在諸多文獻當中，以快速傅立葉轉換使用最為廣泛。然而，有相當多的研究指出，直接地使用快速傅立葉轉換必須遵守其相對應的限制。因此，本文針對簡單又快速收斂的適應性類神經網路進行探討，在檢測諧波的實驗中發現，一旦頻率受到變動，將會導致分析結果不準確，特別是在檢測諧波相角時。為了增加適應性類神經網路的實用性，本文針對頻率偏移的部分做改善，利用普羅尼法可以準確地檢測到基頻，成功地改良此方法。
最後採用IEEE 1459-2000試用標準來進行電力量的檢測。在本論文中，我們亦利用圖形化介面的開發環境LabVIEW建置了量測系統，來驗證本文所提方法之效能，實驗結果證明，此方法不僅快速收斂且量測準確度不受頻率偏移的干擾。

With the development of technology, the power electronics have widely be used. This would make power quality draw much attention. Among of them, the harmonic pollution is an important disturbance source, which would influence the operation of power electronic devices. For the general end users, it may only cause the short-term power interruption in the electrical apparatus. But for the large electrical equipments, harmonics could lead to fault and even cause economical problem. Therefore, the detection of power quality is a noticeable issue.
In order to provide good power quality, it is necessary to perform power system harmonic analysis firstly and propose the improved strategies. Among numerous literatures, the fast Fourier transform (FFT) is one of the widely used approaches. However, most research has pointed out that it is necessary to meet the requirements when directly adopting the fast Fourier transform. Therefore, the adaptive linear neural network (ADALINE) with simple structure and fast convergence will be discussed in this thesis. In the experiment of harmonic detection, it is fount that once the fundamental frequency deviation is present, the estimation results would be inaccurate, especially for the detection of phase angles. To enhance the practicality of adaptive linear neural network, this thesis makes the improvement for fundamental frequency deviation. The fundamental frequency can be estimated accurately by Prony’s method.
Finally, IEEE 1459-2000 trial-use standard would be adopted to perform the measurement of power quantities. In this thesis, the graphical development environment LabVIEW would be used to build the measurement system and to verify the performance of proposed approach. From the experiment, it is shown that the proposed algorithm not only can achieve fast convergence but also can be very accurate without the interference of the fundamental frequency deviation.
