Protection
application leader in project to integrate newly refurbished
1.6 MVA hydro generator with existing 800 KVA hydro generator
interconnected with a 25 kV feeder (with tapped load) to a 2MVA
diesel generator plant (Clayton Falls expansion project).
-
Protection
application leader in project to integrate a 3.5 MVA diesel
substation to the BC Hydro integrated transmission system with
a 174 km 138 kV transmission circuit. Tapped loads of 6 MVA
and 1 MVA were supplied from this transmission extension (1988-1989).
-
System
design and settings for remedial action schemes for control
of voltage, frequency, and stability, such as overload protection
for 500 kV submarine cables 5L29 and 5L31 (1996-1998), load
shedding protection to prevent voltage collapse(1993-1995),
controlled islanding protection against dynamic swings during
high imports (1998).
-
Protection
application leader for project to connect two 50 MVA hydro-generators
to the BC Hydro 60 kV subtransmission system (Stave Falls Generation).
Conducted protection application studies for generator and transformer
protection systems.
-
Protection
application leader in project to build new 138 kV distribution
substations at Oyster River and Qualicum Beach on Vancouver
Island. Conducted protection application and coordination studies
for transformer, distribution bus and distribution feeder protection.
-
Leader
of project to replace obsolete (type HZ) distance protection
relays on 155 transmission line protection systems in British
Columbia. Participated in this project by conducting application
and coordination studies and preparing settings sheets for 49
systems, of which 20 were for transmission lines operating at
138 kV or higher. Of the 20 systems rated 138 kv or higher,
7 were rated 230 kV. (1986 - 1992)
-
Participant
in project to provide special protection system for thermal
overload protection for two 500 kV submarine cable circuits
from mainland of British Columbia to Vancouver Island. Participated
in this project by conducting application studies and coordination
studies with thermal overload capability, and calculating required
settings. (1996 to 1999)
-
Leader
and participant in project to modify nine 500 kV shunt reactor
protection systems at three substations in British Columbia
to prevent tripping of associated transmission lines when the
circuit switcher used to energize the reactor did not close
all three poles simultaneously. Conducted application studies
to design protection modifications. (six months, 1997-1998)
-
Participant
in project to replace 230 kV shunt reactor at Ingledow Substation
in British Columbia. Conducted protection application study
to determine whether existing protection would be suitable for
new reactor. (two months 1994)
-
Participant
in project to provide a special protection system for automatic
load shedding to prevent voltage collapse in the Lower Mainland
and Vancouver Island areas of British Columbia. Conducted protection
application study and prepared relay setting sheets for voltage
and reactive power protective relays at six 230 kV substations
and one generating station and one HVDC terminal station. (two
years, 1993 - 1995)
-
Participant
in project to add a 12 kV shunt reactor to the tertiary winding
of a 500-230 kV auto transformer at Cranbrook substation in
British Columbia. Conducted protection application and coordination
studies and prepared relay setting sheets. (one year, 1993)
-
Participant
in project to construct a new 500 kV transmission line from
Williston to Kelly Lake substations in British Columbia. Conducted
protection and application studies for associated transmission
line and station equipment protection systems and prepared relay
setting sheets. Transmission line protection system was first
application in BC Hydro of digital protection for 500 kV line
protection. Protection systems included features for high resistance
ground fault protection, single phase tripping and reclosing,
synchronised switching to reduce surges, and tolerance for in
line series capacitor. (three years, 1992 to 1994).
-
Participated
as protection specialist in interconnection impact studies and
interconnection facilities studies for numerous generators ranging
in size from 1 MW to 225 MW.
-
Participant
in project to replace obsolete (type KD) electromechanical relays
on 80 transmission and subtransmission lines (1999-date)
-
Specified
and applied the first overload protection devices that included
accurate thermal models for transmission lines and transformers
(1998 – 2000)
-
Specified
and led the application of the first non conventional instrument
transformers on the BC Hydro system for protection purposes
(NXTPhase optical current and voltage transducers applied in
monitoring mode for protection of 230 kV, 125 Mvac shunt capacitor
and 145 Mvar Shunt reactor.
-
Protection
application leader in project to interconnect 230 kV and 60
kV transmission of Aquila Networks Canada to BC Hydro’s Kootenay
Canal generating station (2001 – 2003)
