摘要:	諧波偵測係為交流系統藉由比流器與比壓器進行訊號轉換取得之訊號，有許多文獻研究交流系統之諧波且有許多成果。至於在直流系統中的漣波之諧波，除了對漣波振幅與它的反應時間外，很少有在這個領域上的研究或調查。本文提出一個新穎的研究技術和分析的方法，可以運用在各種操作的條件下進行調查與研究工作，這個研究提出一個新的諧波量測方式，以探測器偵測捷運系統上的軌道電磁場，截取直流牽引電力系統漣波之諧波資料及分析，此研究工作以台北高運量捷運系統牽引電力之直流鏈進行訊號與諧波之量測與分析，這個作法係利用電聯車運轉於軌道上，並分別以靜態與動態等不同條件下進行量測與分析工作。本研究提出新式探測器在直流牽引電力系統上能精確地量測漣波與諧波數據並加以分析且能消除雜訊與電磁干擾。本文係由捷運軌道電磁場量測結果展示出新式探測器在系統上的可應用性與適應性。直流漣波之諧波訊號能被應用在軌道系統上的信號特性與系統整合訊號相容性分析，對於軌道系統上的設備與訊號相容具有相當的助益。對於捷運電聯車、號誌與供電系統之設計與營運後之維修調整能獲得有效地控制及充份地協調，以利供電系統與電聯車負載系統皆能精確控制且提高系統運轉的可靠度與舒適性。 The harmonic detection for the alternating current system is performed by the fixed current and voltage ratio transformers as well as transducers. There are many literatures about the harmonics of the AC systems with innumerable results. As to the ripple harmonics in the direct current system, there are few investigations on the ripple harmonic except the ripple amplitude with its corresponding response time. This work present a novel technique and analysis method that can be utilized under various operating conditions. This study presents a new measurement method with a search probe to detect the magnetic field on the rails of the mass rapid transit systems for predicting the harmonics of the ripple in the DC traction power systems. This work measures the signals and harmonics on the DC link of the traction power of the Taipei Mass Rapid Transit System under the static and dynamic status as a train running the rail road. This study proposes a novel device named the search probe that can precisely analyze the ripple harmonic in the DC traction power and eliminate the noise and electromagnetic interference on the measurement data. The field measurement results demonstrate the adaptability of the presented search probe. The harmonics in the DC ripple signals can be appied to analyze the characteristics and compatibility with the signals in the railway.
