Abstract
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.
