run using IOTAPE=l in Namelist OPT. The data
includes field layout, heliostat design,
receiver dimensions, tower height, etc. so that
the required performance input Namelists FIELD,
HSTAT, REC, NLFLUX, and NLEFF should not
redefine any of these values.
Constraint: ITAPE = 2 for design calculations only
Default: ITAPE = 0
(1II.A-1 ,VI,VI.A)
Power level, in MW, of optimized system stored on Unit 30
to be rerun in detailed performance calculation.
Constraint: ITAPE = 3
Default: TDESP = 100.0 (MW) (VI .A-5)
Latitude, in degrees, of solar plant location.
Constraints: 0 5 PLAT 5 90.0 (northern hemisphere)
Default: PLAT = 35.0 (") (Barstow) (III.B-1,1II.B-3)
Altitude, in km, of solar plant location.
Default: ALT = 0.65 (1II.B-2)
Parameter specifying insolation vs. time model: Note
additional variables in namelist BASIC to be defined
with each option:
= 0, Meinel model; value for ALT required;
= 1, Hottel model; value for ALT required;
= 2, constant equal to SOLCON;
= 3, Allen model; values for PRES or DPRES, and
H20 or DH20 required;
= 4, Moon model; values for PRES or DPRES required.
Default: INSOL = 0 (III.B-2,III.B-3,III.H)
Value of constant insolation, in kw/m2, used with
INSOL=2 option.
Constraint: INSOL=2
Default: SOLCON=0.95 (kw/m2) (1II.B-2)
Control parameter for site dependent weather factors:
= 0, uniform weather factor for entire year;
defined by WEATH if INSOL = 0, 1, 2 or by
PRES (INSOL = 3,4) and H20 (INSOL = 3);
= 1, varying weather factor for each of the NYEAR
calculational days defined by DWEATH(1) if
INSOL = 0, 1, 2 or by DPRES(1) (INSOL = 3, 4)
and DHPO(1) (INSOL = 3).
= 2, uniform weather factor for entire year,
based on reference latitude; calculated by code.
Constraint: If IWEATH = 0, define WEATH, PRES, and/or
H20 for site.
If IWEATH = 1, define DWEATH, DPRES, and/or
DH20 for site.
Default: IWEATH = 0 (1II.B-3)
