Interactive object-oriented simulation of interconnected power systems using SIMULINK.

n object-oriented power system simulation environment is constructed using the SIMULINK dynamic system modeling software. The environment is well suited 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 block for each system component. For large scale simulations, the dynamics of portions of the network can be combined into collective blocks, with parameters managed as data arrays accessed indirectly using string mnemonics. The advanced numerical capabilities built into SIMULINK provide an excellent simulation engine for the nonlinear models. Offline analysis is available through the extensive capabilities of the MATLAB environmen
