碩士 === 國立高雄應用科技大學 === 電機工程系碩士班 === 95 === This thesis investigates the transient characteristics of three phase transformers in thermal power plant. The nonlinear characteristics of transformer are analyzed at first. Then ATPDraw is applied to construct the models of transformers and other equipments in the system, the electromagnetic transient program ATP is used to simulate transient phenomenon of system. Finally, the simulation results are analyzed and discussed. Some improving strategies are proposed for the potential harm of transformer transient and the ATP simulation is performed once again. Simulating results demonstrate that these strategies are helpful to reduce the damage of transformer and to ensure the safe of equipments and the normal operation of units.
