中文摘要 本文旨在增強電力訊號頻率之估測性能,同時探討估頻策略適用時機及限制,進而提出一種適用廣泛且頻率估測準確度較高之估頻策略。本文模擬四種不同訊號環境,以分析各種變因對於頻率估測結果之影響,並研製結合微控制器之硬體電路,且將其應用於負載用電資訊監視,同時經由家用電器用電情形加以探討,而由分析及量測結果可知,本文所提方法確可適於用電資訊監視之應用輔助,並可擴展至與智慧電網整合,具有工業應用參考價值。
英文摘要 The thesis is aimed to improve the estimation performance of power frequency and investigate the applicable scenarios and limitations. The method was evaluated under four different testing environments, through which the influences of various factors have been prudently analyzed. This strategy was further realized by the hardware circuit with the assistance of a microcontroller, by which the completed circuit has been applied to load monitoring and home appliance inspection. From the analysis and measurement results, they have validated that this proposed method serves as an application support for electricity information monitoring, possessing a potential of extending to smart grid with high industrial contribution values.
