Series capacitor installations in the B. C. hydro 500 kV system

This paper describes the series capacitors installed in the 500 kV 580 mile long Peace River transmission system in British Columbia, Canada. The installations feature one of the world´s biggest banks (1012 MVAR installed capacity), internally fused capacitors, and electronic control system. The aspects discussed are general design features, portection and control functions, commissioning tests and staged fault tests. Recent operating experience with these stations is also submitted. The information given here would be valuable for utility planners considering series compensation.
