摘要

This paper deals with the dynamic modeling of the synchronous generator (SG) and the simulation of different events in MATLAB/Simulink environment. A perfect symbiosis is achieved between the load, the rotor dynamics, the electrical part and the excitation system to obtain an efficient SG model suitable for most electrical power plants functioning with. The resulting flexible and versatile model can be used to perform various tests such as: the classical three-phase sudden short-circuit test, the field short-circuit test, the load rejection and line-switching tests. In order to prove the effectiveness of the proposed model, it is inserted in a full hydropower plant and extensive simulations using MATLAB/Simulink program are performed and discussed for different tests and plant scenarios (automatic voltage regulator (AVR) on and off).
