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)
  • 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.

  • 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)
