CLIC Meeting May 2009 Preliminary Studies of the Electric Power Distribution for CLIC Cezary JACH (EN/EL)
CLIC Meeting May 2009 Technical Studies for the Electric Power Distribution for CLIC • Power balance • Layout • Variants of the power distribution system • Next steps
Power Requirements • Total consumption of active power = 415 MW • Assuming an average power factor of 0.85, the apparent power will be approximately 500 MVA • 80% (400 MVA) of the load located near central complex (CERN Prevessin, new substation) • 20% (100 MVA) of the load located outside central complex (remote substations)

Major Cost Drivers • Power requirements • Connection to 400 kV Grid via new transmission line? • Centrally located main substation (distribution voltages, number of transformers, switchgear, protection, monitoring, etc.) • Remote substations (transformers, switchgear and 400 V panel-boards) • Cables in the tunnel (?) using loop configuration • Transformers (?), panel-boards in tunnel • Emergency generators, cabling, transformers, etc. associated with safety system
What’s Next? • Preliminary design (chronologically) • Loads (voltage, apparent power, power factor, harmonics, locations, etc.) • Network topology (choice of variants, machine and service networks, redundancy, safety networks, underground facilities, etc.) • Main substation preliminary design • Remote substations preliminary design • System simulations • Cost estimate
What’s Next? • June 2010 • Preliminary Design Report • Cost Estimate • Available Resources - discussion
