本論文旨在探討微電網過電流電驛之保護協調設定，利用Matlab/Simulink模擬軟體建構出具微電網特性之配電網路，系統中有不同型式之分散式電源，如柴油引擎發電機、風力發電機及太陽能發電模組。微電網可能運轉於併網運轉模式或孤島運轉模式，並且需要在任何型式的故障下皆能受到保護，因此，本研究分別討論微電網在併網運轉模式與孤島運轉模式下之保護協調規劃。在電驛設定方面，透過系統三相短路故障及單相接地故障電流分析，使用粒子群優化法來設定過電流電驛與接地過電流電驛之始動電流值與時間標置值，並透過微電網中的智慧型電子裝置與通訊系統調整電驛參數，讓微電網在任何運轉模式下皆能維持保護協調，以確保微電網的供電可靠度與連續性。 

In this thesis, a distribution network, characterizing the microgrid, is constructed with a solar power system, diesel engine generators and wind turbines established by using Matlab/Simulink. Microgrid may be operating in the island mode or connected mode. And it needs to be protected under any type of mode. Therefore, this thesis is discussed the coordination optimization of overcurrent relay for microgrid system. In the relay setting, through the three-phase fault current analysis and ground fault current analysis, using the particle swarm algorithm to set the pickup current value and the time dial setting of the overcurrent relay and ground overcurrent relay. In addition, central control unit is joined to microgrid for adjusting relay parameters; therefore, protective systems can maintain protective coordination under different modes.
