因早期配電系統在設計規劃及實際運轉時，均未考慮風力發電機組併網後所可能造成之影響。因此一旦風力發電機併網運轉後，將直接衝擊原有配電系統的設備安全與短路特性；故本文主要探討風力發電機倂入配電系統後，對既有保護協調的影響，並提出具體的建議以降低風力發電機所造成之衝擊。另外為了使配電系統故障發生之後的停電區域減到最小與停電時間降到最低；本文利用增廣關聯矩陣與線性規劃法，減少有關過電流電驛設定大量的人工計算時間與提高其準確度。若因故須進行系統轉供，亦能利用本法迅速取得相關過電流保護電驛之最佳設定。

Traditionally, wind generation was not involved as a part of the distribution systems during design, planning and operating considerations. In consequence, when once the wind generation fed to distribution system it will significantly affect the existing system’s safety and short-circuit characteristics. Hence, this thesis will mainly focus the possible impacts on the protection coordination analysis due to wind generation embedded into distribution systems. In case of short circuit fault occured in system, to reduced the power cut-off region and minmized the power shut down, the augmented incidence matrix and the linear programming method were introduced; this method not only decreased the manual calculation time but also could enhance the accuracy to obtain the optimal settings of overcurrent relays. If the power reconfiguration is required, the new optimal settings for the relevant overcurrent relay by performing the same processes.
