Colin E. J. Bowler
Graduated in 1966 with a BS in Electrical Engineering
from
From 1967 to 1994 he was employed by General Electric as
a Generator Engineer, and Power Systems Engineer specializing in
turbine-generator reliability concerns from power system operations.
From 1994 to 2002 he worked for ABB US T&D as an
R&D Consultant in Power Systems and as principle developer of DSP based Power
Electronic controls for Medium Voltage
Static-Switches and Reactive Compensation Systems.
Technology Contributions:
Discovered the SSR Torsional Interaction Phenomena and
developed state-space modeling computer simulation for the turbine-generator
and network for evaluating torsional stability margin.
Developed comprehensive SSR mitigation, control, and
protection equipment and applied on nine Western-Area turbine-generators.
Developed and applied Monte-Carlo computer simulation
methods for evaluating transmission-breaker reclosing practices, to establish
the reliability effect on turbine-generator operation.
Developed a high-speed SSR
protection and monitoring system, providing secure and dependable
protection of turbine-generators from transient resonance phenomena.
Developed a new concept synchronous-phasor
measurement system, with very high bandwidth, suitable for control and
monitoring of wide-area power-system disturbances.
Mr. Bowler is currently President of Instrumentation
Technology Inc. a provider of DSP based SSR Protection Systems, and DFR and PMU
monitoring and control systems for wide-area system dynamic performance. Mr.
Bowler is a member of IEEE and has authored/coauthored
many papers on SSR, Turbine-Generator Torsional Interactions, FACTS and System
Dynamic Performance.
John Tarnawski:
Mr. Tarnawski is currently a
Vice-President with Instrumentation Technology Inc. responsible for
instrumentation design.
From 1970 to 1975 he was
employed by Dudley Observatory responsible for instrumentation
payload-integration for scientific evaluation of micro-meteorites on Skylab,
and with Rocket and high altitude balloon deployment.
From 1975 to 1983 he was a
Design Engineer with Instructional Industries responsible for
electromechanical, analog and digital circuit design of educational products,
including design, test, documentation, field installation and support.
From 1983 to 1991 he was
employed as a Product Engineer by Relay Testing Systems responsible for the
design of automated test equipment (ATE) on Multibus based microprocessor
instrumentation systems. Design responsibility included circuit and package
design for electronic, thermal and mechanical integrity.
From 1991 to 1996 he joined
General Electric Power Systems as a Technical Specialist responsible for the
design, test, field installation, and support of Series Capacitor Transmission
Compensation Systems. Projects included PG&E, WAPA, BPA, SSPB, and Hydro Quebec.
During this time he also designed the electronics for various digital signal
processing (DSP) based systems for evaluating response of Steam and Gas Turbine
Generators.
From 1996 to 2002 he was a
Consulting R&D Engineer for ABB Power
Systems responsible for the instrumentation and power electronic control design
of DSP based Medium Voltage power quality systems including Static-Transfer
switches, and Reactive compensation systems.
