pf_power_variables

Module containing global variables relating to the PF coil power conversion system

acptmax = None module-attribute

average of currents in PF circuits (kA)

ensxpfm = None module-attribute

maximum stored energy in the PF circuits (MJ)

i_pf_energy_storage_source = None module-attribute

Switch for PF coil energy storage option: - =1 all power from MGF (motor-generator flywheel) units - =2 all pulsed power from line - =3 PF power from MGF, heating from line (In fact, options 1 and 3 are not treated differently)

pfckts = None module-attribute

number of PF coil circuits

spfbusl = None module-attribute

total PF coil circuit bus length (m)

spsmva = None module-attribute

sum of PF power supply ratings (MVA)

srcktpm = None module-attribute

sum of resistive PF coil power (kW)

vpfskv = None module-attribute

PF coil voltage (kV)

peakpoloidalpower = None module-attribute

Peak absolute rate of change of stored energy in poloidal field (MW)

maxpoloidalpower = None module-attribute

Maximum permitted absolute rate of change of stored energy in poloidal field (MW)

poloidalpower = None module-attribute

Poloidal power usage at time t (MW)

init_pf_power_variables()

Initialise PF coil power variables
