Title: 1200-kV system study

Abstract

The 1200kV Systems Study Project consisted of two major tasks: definition of performance requirements for a 1200kV circuit breaker for use in a gas-insulated substation; and performance analysis of a 1200 kV insolator/disconnect switch for gas-insulated substation. For the first task, the performance requirements included: insulation requirements - 60 Hz, switching surge and lightning, both phase to ground and across the open breaker; prospective transient recovery voltage requirements related to fault current interrupting; an opening scheme capable of limiting phase to ground and across the breaker overvoltages resulting from line dropping and out of phase switching; a closing scheme capable of limiting line overvoltages during reclosing to 1.5 pu (2 percent level). The investigation of each of these items and of lightning characteristics and effects is discussed. The 1200 kV disconnect switch study analyzed bus energizing, bus de-energizing, transformer de-energizing, and the effect of hysteresis losses. Results from these analyses are presented. (LCL)
