本計畫主要目標為研究區域電網故障偵測及保護電驛動態設定之研究，為達此目的本計畫將研究分散式電源併聯、故障分析技術及饋線保護協調相關規範，並依據核能所微電網系統為基礎，建立小型微電網系統，其微電網系統包含太陽能發電系統、儲能系統與負載。並依此探討分散式電源在不同運作模式下，當市電電壓及頻率超出併網規範時之故障電壓與電流特性分析。此外，本計畫亦探討分析饋線主幹、分歧線與微電網之動態保護協調設計，提出故障訊號分析技術、故障環境建立測試與模型驗證。 ;The main objective of this project is to study the fault detection and dynamic setting of protective relay for distributed area. To achieve this goal, the grid-connected standard for distributed generator, fault analysis technology and feeder protection specifications are researched in this project. Moreover, the microgrid system of the institute of Nuclear Energy Research (INER), including PV system, storage system and loads, is adopted to established the simulation models. When the voltage and frequency of the power grid exceed the grid connection specifications, the voltage and current characteristics of the distributed generators under different operation modes are discussed in this study based on the established models. In addition, the analysis of the dynamic protection coordination design of the feeder, the divergent line and the microgrid will be studied in this project to provide the fault signal analysis technology, fault environment establishment test and model verification.
