隨著風力發電技術的進步,風場投資興建隨之興盛,因此風場併聯輸電網後對於系統之影響格外重要。本論文旨在分析虛功補償器對於含有風場的區域輸電網路其改善系統穩定性的效果,本論文並應用電壓穩定度分析及配合適當的搜尋方法來決定系統中設置虛功補償器之適當地點以及容量大小。本論文提出的方法除針對IEEE 14 bus system與IEEE 30 bus system,以及台電東部電力系統進行模擬外,本論文亦利用電力暫態分析軟體ETAP分析東部電力系統之電壓分佈情況,並使用Matlab軟體與PSAT軟體分析風場併網及評估靜態虛功補償器(Static Var Compensator, SVC)和靜態同步補償器(Static Synchronous Compensator, STATCOM)對系統造成之影響。研究結果顯示,靜態同步補償器與靜態虛功補償器確實能夠有效改善系統在事故干擾下之動態特性,可供虛功補償器設置規劃與風力發電併網分析之參考與應用。
The investment in the construction of the wind farms have flourished with the advanced technology of wind power generation. However, the impacts of the system are extremely important after the wind farms connected to the transmission system. This thesis focuses on analyzing Flexible Alternating Current Transmission Systems (FACTS) that can improve stability of the power system with wind farms in the regional transmission network. This thesis determined the proper size and location for the reactive power compensator in the system by Applying voltage stability analysis and appropriate searching methods. The proposed methods in this thesis tested in the cases of the IEEE 14 bus system, IEEE 30 bus system and Taipower Eastern Power System for simulation and verification. The thesis used ETAP to analyze the variations of voltage and utilized Matlab/PSAT (Power System Analysis Toolbox) to estimated the effect in the Static Var Compensator (SVC) and Static Synchronous Compensator (STATCOM) for the system. The research results showed that STATCOM and SVC can really improve dynamic characteristics of the system at the fault interference. They can serve as the reference and application for planning and setting of FACTS and impact study of power systems connected with wind farms.
