近年來之電力系統中，由於非線性負載之急遽增加，致使供電品質受到大幅影響，因此如何有效測得電力訊號之各項數據，並進行整體性之分析，進而在最快時間內掌握污染源之相關資料，確已成為現今電力品質監測之重要技術。本文即提出應用.NET平台之程式語言，並針對電力擾動訊號分析之所需，建構一可攜式電力品質分析系統。文中，利用.NET跨平台之特性，分別於客戶端及伺服端撰寫其電力品質分析所需之相關程式，且因智慧型行動電話具高度可攜性及無線網路通訊之功能，故可將其應用於客戶端之電力品質監測，且於伺服端建構之圖形化介面，並可供使用者載入歷史數據。為驗證本研究所提方法之可行性，並已將該方法經由擾動訊號予以進行縝密測試，應可佐證本研究於電力擾動訊號分析之可行性。

Following the increased use of nonlinear loads connected in the modern electric power system, the quality of supplying power is seen degraded. Therefore, it is critically important to measure the electric power data and perform the analysis such that the polluted sources can be earlier located. In view of such importance, this thesis has proposed an integrated approach to implement a portable electric power quality analysis system, where the .NET platform was mainly utilized for the cross-platform considerations. In the propose method, thanks to the high portability of Smartphone and wireless communication, the monitoring data can be easy to deliver to the client side where the user interface was also built up. Then, at the server side, it was responsible for the electric power quality-related computation. In order to validate the feasibility of the method, several disturbances were also simulated and tested via the proposed system. Test results helped reveal the feasibility of the method for the application considered, which would be also beneficial for electric power quality monitoring study.
