Nonlinear
Stability Analysis of the Large Power System
Mani V. Venkatasubramanian is developing a
framework for comprehensive stability analysis of
power system models. The project is funded by NSF.
Novel stability analysis tools for analyzing the interconnected
behaviour of the pwer system as related to small-signal
stability and transient stability are proposed. The
emphasis in the project is on the study of nonlinear
oscillatory phenomena. (for more information please

Power
System Model Estimation and Verification
Mani V. Venkatasubramanian is developing computer
algorithms for direct estimation of dynamic model
parameters using external measurements. The objective
of the project which is funded by EPRI is to work
towards a model estimation toolbox which would facilitate
automatic fast extraction of dynamic parameters of
generator and load models using mostly external measurements
from the units. (for more information please contact:

Enhancements
of Inter-Tie Stability Using Thyristor Controls
Mani V. Venkatasubramanian is working towards
developing novel control strategies for thyristor
control devices in the Northwest which would improve
the transient stability properties of the western
inter-tie lines. in this project, funded by Bonneville
Power Administration (BPA), we are developing new
control strategies for fast and sow voltage control
of switching capacitor banks and transformers in the
BPA grid. (for more information please contact: mani@eecs.wsu.edu)

Power
System Electromagnetic Compatibility
ELF Magnetic Field Bioeffects Research. Althought
interest in the ELF magnetic field (EMF) bioeffects
issue in the United States is not as great as it was
a few years ago, it remains as a research issue and
one of greater interest overseas.In May 2000, Prof.
Robert Olsen was invited to lecture in Japan at
Nagoya University, hubu Electric Power Company, Kyusgu
Institute of Technology and the Federation of Electric
Power Companies on the status of the EMF issue in
the United States. His slided are available as a power
point presentation by writing to him at olsen@eecs.wsu.edu.

Optical
Fiber Communications Research
Prof. Olsen and his colleague Monty Tuominen
of the Bonneville Power Administration have worked
to develop accurate models for predicting volatges
and currents induced on ADSS cables. Prof. Olsen
has also worked with graduate student Ken Edwards
and Prof. Pat Pedrow to develop instrumentation
to measure the contamination level on ADSS cable.
This information is needed to predict the susceptibility
of ADSS cable to dry band arcing damage (for more
information please contact: olsen@eecs.wsu.edu.)

Electromagnetic
Compatibility of Power Lines and GPS receivers
The global positioning system (GPS) is a satellite-based
radionavigation system that has many new civilian
applications for the position, velocity, and time
information it can provide. As GPS use expands, it
becomes more important to evaluate any potential sources
of interference. One issue that is sometimes raised
is the potential for degraded perfomance of GPS receivers
when they are used near electric power facilities.
of specific interst is the use of the GPS satellite-based
microwave signals under or near power line conductors.
With support from EPRI, Prof Olsen has been
studying the possibility of this interference. It
has been shown unlikely that power line consuctors
will interfere with use of the GPS satellite signals.

Portable
ADSS Surface Contamination Meter
P.D Pedrow, R.G. Olsen and masters
students K.S. Edwards with the School of Electrical
Engineering and Computer Science have proposed new
research. Fiber optic cable of the type all dialectric
self supporting (ADSS) is known to have a limited
installation lifetime in some environments when installed
near high voltage trnasmission lines. Dry band arcing
has been identified as a contributing factor in the
short service life for some of these cables. it has
been hypothesized that contamination on the jacket
of the fiber optic cable will be an indicator of cable
installations that will have a short service life.

Corona
Optimization of High Voltage Hardware
Doctoral student Dave Phillips completed his
doctoral dissertation on high voltage experiments
and computer simulations on the corona perfomance
of various electrode shapes. His work now focused
on experiments that measured the onset voltage of
electrodes with different shapes. Various elecrode
shapes were designed and constructed. A sensitive
corona pulse detector system and light intensifier
was used to measure corona onset voltage. These values
was compared with theory for three different electrode
geometries.

Power
System Operation and Control
Anjan Bose and his graduate students continue
thier works on power system security, especially the
on-line analysis of dynamic security which tends to
determine the transmission capabilities on the Western
system as well as some others
Emilia Nobile, Anjan Bose and Kevin
Tomsovic are examined the feasibility of genration
control (AGC) becoming an ancillary service to determine
the technical impediments, like metering and NERC
perfomance criteria, and is now doing the same for
voltage control.
A major research thrust has been initiated in the
area of the future communication and computer networks
needed to operate and control the electric power system,
including the power markets.

Advanced
Computer Applications
Deregulation, increased system complexity, improved
data gathering and new generation technologies have
created the need for more sophisticated computational
and information processing approaches to power system
problems. Kevin tomsovic has been applying
optimization, "intelligent" system methods,
and other advances in computational technology to
address these needs. (for more information please
