  • 在這個能源需求不斷上升化石能源不斷稀缺的時代,再生能源已
    然成為能源發展的重點,其中再生能源的裝機容量中以水力、風力及
    太陽能最大,太陽能也為近期發展最為重視的發展目標,除了不斷擴
    大建設太陽能的建置外,由於太陽能的建設通常為大範圍定期的巡檢
    費時費力又不一定找得出故障,必須思考設計出管理太陽能發電系統
    的故障狀態檢測機制以提高管理案場的可靠性,透過於案場設備讀取
    所得到的設備數據進行數據分析,以快速找出太陽能故障的位置並加
    以排除,以維持太陽能電廠的最佳發電性能與太陽能系統的效益。
    有鑑於此,本研究旨在研究如何檢測太陽能系統故障,其中包含:
    (1) 研究太陽能監控架構及故障狀態檢測方法,(2) 監控系統的相關
    設置,(3) 故障狀態檢測的機制建立,(4) 撰寫故障狀態檢測相關程
    式語言相關功能,(5) 實際運行並找出故障位置,(6)實際案場驗證故
    障並分析原因,經測試得以證明藉由有效的故障狀態檢測方式可以在
    短時間內發現故障並修繕減少發電損失,該方法可對於大型太陽能電
    廠在故障狀態檢測與電廠效能評估上,提供一個具有價值的參考依
    據。


    In this era of rising energy demand, petrochemical energy is
    constantly scarce, renewable energy has become the focus of energy
    development, among them, the installed capacity of renewable energy is
    hydropower, wind power and solar energy. Solar energy is also the most
    important development goal for recent development. In addition to
    continuously expanding the building of solar energy, since the
    construction of solar energy is usually a large-scale regular inspection, it
    is time-consuming and laborious and may not necessarily find faults. We
    must think about designing a fault diagnosis mechanism for managing
    solar power generation systems to improve the reliability of the
    management case. Data analysis is carried out through the equipment data
    obtained by reading the equipment in the field. In order to quickly find
    the location of the solar failure and eliminate it, to maintain the best
    power generation performance of solar power plants and the benefits of
    solar systems.
    In view of this, this research aims to study how to detect solar system
    failures, including: (1) Research on solar monitoring architecture and
    fault diagnosis methods, (2) Related settings of the monitoring system, (3)
    Establishment of fault diagnosis mechanism, (4) Compose programming
    language related functions related to fault diagnosis, (5) Actual operation
    and find out the fault location, (6) The actual case verifies the failure and
    analyzes the cause, tests have proved that through effective fault
    diagnosis methods, faults can be found and repaired in a short time to
    reduce power loss. This method can be used for fault diagnosis and power
    plant efficiency evaluation of large-scale solar power plants. Provide a
    valuable reference basis.
