TITLE: Power System Stability (Thesis)) | |
Abstract
The objective of this thesis project is to investigate and understand the stability of power system, with the main focus on stability theories and power system modeling. The thesis looked into the effects that advanced control techniques have on electrical power generation system and transmission system. The thesis first explained the definition of power system stability and the need for power system stability studies. It then proceeded to discuss on the various stability problems after which the thesis provided a brief introduction on basic control theory and study. Next the thesis examined the concept of system stability and some stability theories. The thesis then performed a power system modeling and simulation of a two-machine, three bus power system. The performance of the power system was simulated with the proposed advanced control technique. The performance points and system parameters were varied to test the robustness of the power system and the effectiveness of the proposed controller. Examples of the parameters that were varied include the fault position λ, the power angle δ and the mechanical power input, pm. Lastly, a conclusion was made on the overall effect of the controller on the power system and the performance of the power system when its parameters were varied
