Realization of a generalized modeling method for ungrounded power systems in Matlab/Simulink

ABSTRACT

Matlab/Simulink provides a customized environment to realize a generalized modeling method previously developed by the authors for ungrounded power systems. Problems of building component models with function blocks and interconnecting them with algebraic loops in Matlab/Simulink are discussed. The system model of a reduced ring shipboard power system is built in Matlab/Simulink according to the model construction procedures. Representative simulation results of various fault scenarios of the reduced system are presented. Comparison of simulation results and speeds of the generalized modeling method and a commercial software package SimPowerSystems, which was developed in Matlab/Simulink, validates the effectiveness of the implementation of the generalized modeling method in Matlab/Simulink.
