能源問題是21世紀最重要的問題之一。風力發電優點為零污染且不會造成環境影響，所以近年來全球風力發電裝設量日漸增加。然而風力發電對於電力系統的影響非常重要，本論文針對風力發電的穩定度的研究。
電力系統模擬主要為EMTP-RV、PSS/E、DSA、PSCAD/EMTDC和DigSILENT，然而這些軟體的主要缺點為不能連接硬體實現。所以OPAL-RT軟體公司開發出一種的軟體稱為RT-LAB，。RT-LAB軟體可先透過模擬器做真實系統模擬並且透過硬體連接迴路實現模擬結果。本論文利用RT-LAB軟體建立真實系統模擬，並且研究風力發電機與傳統同步發電機對於電力系統的影響。
本論文將以RT-LAB軟體為基礎，探討風力發電對於電力系統穩定度，其中論文的貢獻主要列出幾點：
1 傳統同步發電機會因為轉子轉速模式而影響系統穩定，本論文先敘述傳統同步發電機對於電力系統影響，其次推導出感應發電機的係數、並且比較目前雙饋式感應發電機控制模式的優缺點。最後以單機系統和三機系統做為測試系統，計算特徵值和模擬暫態穩定度。
2 傳統同步發電機對於電力系統發生頻率事故時，其實功率會有明顯影響，但風力發電機的反應卻很慢。為了加強風力發電機組頻率穩定，必須在風力發電機上加入控制迴路。本論文工作首先推導頻率與負載的關係，說明負載確實會與頻率互相影響。並且由三區域系統和三機系統做模擬驗證，其中為了加強頻率穩定，本論文加入模糊控制。其次說明雙饋式感應發電機的頻率控制策略，並以三機系統做模擬驗證。

Energy problems are one of the most important issues in 21st century. The advantages of wind power generation is zero-pollution and not cause environmental impacts, so the global wind power generation of capacity is increasing in recent years. However, the impacts of wind power on the power systems is very important, the wind power stability is discussed in the thesis.
The major of power simulators are EMTP-RV、PSS/E、DSA、PSCAD/EMTDC and DigSILENT, however the major drawback of these simulators is that it can realize by connecting hardware. So the OPAL-RT software corporation develops a software which is called RT-LAB. The RT-LAB software can use software to do real-time simulations and realize the simulation by Hardware-in-Loop. The real-time simulation is built by RT-LAB software, and the impacts of wind power and traditional synchronous generator to power systems is researched.
The aim of thesis is to develop the RT-LAB software implements of the wind power on the power systems stability .The main contribution of thesis is listed through the following steps：
1. Because the rotor speed mode of conventional synchronous generator
affects system stability , the thesis first describes the conventional
synchronous generator on the power system impacts, and the induction generator coefficients is derived, and the current control of doubly fed induction generator model the strengths and weaknesses is be compared. Finally, one-machine-infinite-bus system and three-machine system are performed by calculating the eigenvalues and simulating transient stability.
2. Conventional synchronous generator for power system frequency of accidents, the real power will be significantly affected, but the response is very slow wind turbines. In order to enhance the frequency stability of wind turbines, wind turbines must be added on the control loop.The relationship between frequency and load is be derived in the thesis, it indicates that the load will affect the frequency. And simulations of one-machine-infinite-bus system and three-machine system are performed to verify, which in order to enhance frequency stability the thesis add fuzzy control and fuzzy neural control. Secondly, the double-fed induction generator frequency control strategy is described , and three-machine system is performed to do verification.
