本論文利用IEC 61850通訊技術於微電網保護系統中。微電網為許多分散式電源組成，如柴油發電機、太陽能系統等。此外，本論文中介紹電池儲能站於電網中，於尖峰用電時提供電動車充電站使用。利用Matlab/Simulink模擬軟體對微電網進行探討，在孤島模式下與在併網模式下皆須隨時受到保護。因此，本論文中主要目的介紹如何設計有效之保護系統於微電網。由於微電網中含有許多不穩定之負載與分散式電源，使保護上有較高的難度。本論文運用IEC 61850於微電網保護管理系統(PMS)，並且透過智慧型電子裝置(IED)之GOOSE功能於設備間之溝通。在保護方面過電流保護電驛之參數透過線性規畫法，並找出設定之最佳解，並且保護管理系統隨時根據系統之變化而即時更新保護設備之參數，使保護設備間可有較好的協調。而本文利用Matlab/Simulink來模擬微電網故障分析，由模擬結果發現，在傳統保護系統中保護一隨時變更之電網式相當困難的事情，若透過通訊隨時更新保護設備，並且運用GOOSE訊息，可改善傳統保護系統不能滿足之保護，也可使保護系統能有較佳的適應能力，與高可靠度之保護系統。

In this thesis, IEC 61850 communication techniques have been presented to apply in the microgrid protective systems. In nature, the microgrid is embedded with distributed generation systems, such as diesel engine generators and solar systems. Furthermore, batteries are also introduced to store energy for peak power sharing. The whole system is explored by using Matlab/Simulink. Microgird can be operated either in the island mode or connected mode and must be under protected in anytime. Therefore, how to design an effectively protective system for microgrid system is mainly key issue in this thesis. Since the microgrid can be dynamically operated with uncertainly generation and loading. A novel IEC 61850 base Protective Management System (PMS) associated with GOOSE functionality Intelligent Electronic Device (IED) is proposed. The linear programming method has been implemented to relay optimizing settings. Such that relay settings can be adaptively updated follow system condition change to maintain the relays all with well coordination. To demonstrate the proposed idea, the Matlab/Simulink is also used to perform fault analysis of microgrid system. The simulation results shows that it is very difficult to maintain relay coordination if using traditional protection scheme. However, the proposed PMS associated with GOOSE functionality IED is not only optimized the relay settings, but also can always adaptively accommodate the system change.
