An object-oriented power system simulation environment is constructed using
the SIMULINK dynamic system modeling software. The environment is well sui
ted to educational purposes, because the user interface is interactive and
intuitive with a graphical, object oriented model representation. For small
system studies, a model is constructed in block diagram form with one bloc
k for each system component, For large scale simulations, the dynamics of p
ortions of the network can be combined into collective blocks, with paramet
ers managed as data arrays accessed indirectly using string mnemonics. The
advanced numerical capabilities built into SIMULINK provide an excellent si
mulation engine far the nonlinear models. Off-line analysis is available th
rough the extensive capabilities of the MATLAB environment.
