| Abstract: | Synchronous alternator is a key equipment of ship power system and the exact analysis of its short-circuit dynamic process is very important for the alternator and power system protection. Based on an idealized synchronous alternator, this paper analyzes its mathematic equations and builds a software simulation model using matlab s-function. The simulation study of three-phase and phase-to-phase short circuit is finished. The varieties of main parameters in short-circuit dynamic process are revealed vividly by simulation results which prove to be accurate and effective. |
