Design point parasitic load, expressed as a fraction
of the gross electrical output.
Default: REFPRL = 0.103 (III.G-6,11I.G-8)
Fraction of design point parasitic load required for
operation from storage.
Default: FSP = 0.66 (III.G-G,III.G-8)
Fraction of design point parasitic load for operation
electrical generating pumps (feedwater pumps, cooling
tower, etc.).
Default: FEP = 0.0 (III.G-G,III.G-8)
Round trip efficiency through storage.
Default: EFFSTR = 1.0 (1II.G-7)
Plant factor; expected fraction of the year in which
the plant will be on line. In a realistic
calculation of busbar energy cost, PF should be some
value less than 1.0.
Default: PF = 0.90 ( III.G-8,III.H,IV.B-2)
Solar multiple at design point; I/SMULT of the thermal
power at the base of the tower goes directly to the
industrial or electrical process at the design point; the
rest is sent to storage. This variable should also be
defined in Namelist OPT.
Constraint: SMULT 2 1.0
Default: SMULT = 1.5 (1V.C-5,VI)
Parameter identifying industrial process heat run instead
of electrical plant run:
= 0, electrical plant; output in MW,, mills/kw-hr, etc.
# 0, industrial process heat; code automatlcally sets
ETAREF=1.0, FEFF=1.0, REFPRL=O.O, CEGREF=O.O.
Default: IPH = 0 (1II.G-6,V.A-11)
Coefficients for calculating thermal losses based on
receiver area. REFRCl is related to radiative losses,
the rest to convective losses.
Constraint: IRADFL = 0, IRECO) REFRC 1= 16403.0
