BC Hydro Projects


  • 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.
