parabolic trough solar collectors power plants (designe)
1.
2. In the name of the ALLAH , the most
beneficent , the most merciful
Design of parabolic trough solar collectors power plant with
storage system
3. Scope and Aim of Project

27. Heat storage system
One challenge facing the widespread use of solar energy
is reduced or curtailed energy production when the sun
sets or is blocked by clouds. Thermal energy storage
provides a workable solution to this challenge
40. Describe the number of solar collectors
𝑁 𝑃𝑇𝐶 =
313470.637
40.3125
= 7776
For one collector
𝑄 𝑐 =468.105 (kw.hr/day)
Total number of the collectors
N =
313470.316×24
468.105
= 16072
N for solar collectors for day = 9040
N for storage = 7032
Q storage = 7032×468.105 = 3291714.36 kw.hr / day.
41. Size and layout of the solar field
The aperture area of one PTC, AC = trough
aperture × trough length = 5.76×12 = 69.12 m2
The total aperture area of the solar field =
NPTC × AC = 16072×69.12 = 1110896.64 m2
The total solar field area = 3.5×1110896.64 =
3888138.24 m2 = 3.888 km2
