當電力系統發生重大事故可能導致電網解體為數個孤網，並使一些區域分裂成為孤島運轉，如何快速且安全地恢復孤網間的合聯，是大型電網安全運行必須考慮的問題。本論文利用電力暫態分析軟體(ETAP)模擬及分析兩獨立運轉之電力系統合聯時的動態時域響應及運轉操作條件，系統合聯模擬包括兩個案例，金門電力系統及台北69kV電力系統，模擬內容包括電力潮流計算與動態分析。研究內容包括系統合聯時，頻率差、相角差、電壓差造成之影響，及斷路器投入時容許頻率差、相角差、電壓差範圍，與降低頻率差、電壓差之方法。經由模擬分析的結果(操作情況及操作限制)，合聯條件以電壓差小於0.035pu、相角差小於10度及頻率差小於0.3Hz為佳，可提供調度人員在進行系統合聯時的參考。

When the power system is suffered to major outages, the power grid may be divided into several separately independent power systems and some regional islanding power systems. It is required to recombine those isolated power systems into a parallel power system as quickly and safely as possible.The aim of this thesis is to simulate and analyze the dynamic time domain response analysis and the operating conditions for parallel switching of two islanded power systems by the Electrical Transient Analysis Program (ETAP).There are two simulation examples in this thesis, one is the Kinmen power system, and another is the Taipei 69kV power system. The simulation contents include power flow study and dynamic response analysis. The effects of frequency difference, phase angle difference, voltage magnitude difference and the accepted ranges of those different conditions in switching instance should be investigated. The methods to reduce those differences are required. Through the simulations and analyses, the results of the operating situation and limits of operation are obtained. The voltage magnitude difference lower than 0.035pu, the phase angle difference less than 10 degree and the frequency difference less than 0.3Hz are the best parallel switching conditions. It can provide a reference for the power system dispatchers when they parallelly switch two power systems.
