VTechWorks staff will be away for the Thanksgiving holiday starting at noon on Wednesday, November 21, through Friday, November 23, and will not be replying to requests during this time. Thanks for your patience, and happy holidays!
The objective of this thesis is to examine the effect of dynamic
induction machine modeling and polynomial static load modeling on the
stability of electric power systems and to compare the results with
those obtained using constant impedance or constant current load models.
A least-squares curve fit algorithm is developed and used in modeling
static and quasi-static loads as a function of the bus voltage.
A dynamic model for the induction machine which accounts for rotor
electrical and mechanical transients is incorporated into the solution
A test system is analyzed under a variety of loading conditions.
The effect of the induction motor .load inertia constants on the system
stability are also examined. Plots of load bus voltages during the
transient stability period are included.
