| Abstract [eng] |
The final master's thesis is dedicated to investigating the capabilities of an asynchronous generator to damp active power oscillations arising in the electrical power system. In the first part of the study, a literature review is conducted, in which the importance of power system stability is discussed, along with the classification of power system stability based on the main system parameters. This section also analyzes the causes of active power oscillations and the impact of this process on the system. Since the asynchronous generator is modeled using a wind power plant control algorithm in the final research, a review of wind power plants is also conducted. This review identifies different types of wind power plants and the possibilities for damping power oscillations. In the second part, a model is created to study active power oscillations. This section provides a detailed description of the system components used, their parameters, control algorithms, additional controllers, and testing modes. The model is developed using MATLAB software in the Simulink environment. In the third part, the results of the system and the asynchronous generator are presented, which are obtained by examining the active power oscillation process. The results show that the modified asynchronous generator with a wound rotor can be effective in damping both stable and unstable active power oscillations in the system. |
