192 3. GENERAL DESIGN OF A SOLAR THERMAL POWER PLANT

By integrating the above analysis, based on the prediction effect of
dynamic test model on parabolic trough collector, experimental
requirements and process of performance dynamic test of parabolic
trough collector can be summarized: Thermal performance dynamic test
of parabolic trough solar collector shall be conducted under a clear days;
the whole testing process is required to enjoy a solar DNI over 700 W/
2
m ; variation of volume flow of heat-transfer fluid passing through the
parabolic trough collector shall be within 2%. According to the scope of
application of parabolic trough collector, a specific variation scope of
outlet temperature of heat-transfer fluid within the specific parabolic
trough collector can be determined. The testing process consists of
two stages, namely outlet temperature ascent process of heat-transfer
fluid within the parabolic trough collector under normal tracking
concentrating conditions, and outlet temperature descent process of
heat-transfer fluid within the parabolic trough collector under condi-
tions when adjusting the aperture of receiver of parabolic trough
collector to the poor-radiation side. In addition, the test shall be
conducted around the time of the day when the maximum incident angle
appears; for example, for the most common parabolic trough solar
collector arranged horizontally on the north-south axis, the tracking test
for parabolic trough collector shall be conducted within 2 h before or
after high noon every day.
