Research description:
Development of optically activated power system switches.
Development of appropriate load models and power electronic applications
for voltage stability analysis.
Development of an integrated symbolic-numerical software for the purposes
of power system bifurcation studies.
Highlights of accomplishments include the following:
Observance of the zero voltage conducting state for a power electronic
switch
Model for the reactive power response to voltage changes which
incorporates capacitor switching and transformer load tapchangers.
Exhibition on a toolbox bifurcations of the type: saddle-node, Hopf and
singularity-induced.
Lab Facilities:
The Interconnected Power System Laboratory (IPSL).
The main feature of the IPSL is that it uses real-life generators,
transformers, motors, loads, and relays interconnected through
transmission lines to form a power system which operates at a frequency of
60 Hz and a voltage level of 220 V. The general configuration of the IPSL
exhibits the interrelationship between its two main parts: the
interconnected power system and the energy management system (EMS)
emulator. The power system network portion can be reconfigured in a
variety of ways to form 2, 3 or up to 5-bus systems. For more info please
