BC Hydro Projects
Protection


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)

1 Prepared January 2005 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 Hydros Kootenay Canal generating station (2001 2003)
