GB/T 26972-2011Vocabulary of concentrating solar thermal power (English PDF)

2.1 Concentrator tracking accuracy (or tracking error) trackingaccuracy (orerror)

Condenser with respect to the center of rotation of sunlight converged by the condenser to the target surface of the patterned geometric center of the target surface of the target point

The connection between the opening angle, with its multiple measurements of root mean square value (RMS) expressed in units of mrad.

2.2 Concentrator tracking accuracy (or precision tracking, tracking error)

Condenser center of rotation relative to the inner solar concentrator through converging pattern formed on the target surface and the geometric center of the test period Figure

The average case the geometric center of the opening angle connection, multiple measurements of its rms value (RMS) expressed in units of mrad.

2.3 Condenser aperture area

Condenser intercepts the maximum projected area of the solar radiation.

2.4 Converging field lighting area concentratorfieldaperturearea

The sum of all areas of lighting condenser condenser field.

2.5 Condenser surface profile error

The actual surface profile of the condenser and the theoretical surface profile errors caused by inconsistent, including the position error and the tilt error, in which the incident point

Set the desired position is inconsistent with the position error, and the theoretical value of the slope surface of the incident point is inconsistent with the tilt error.

2.6 Field efficiency condensing

Unit of time via the collective field reflected or transmitted light into the heat sink and the mouth of the solar radiation incident on the condenser to the total field area lighting normal

The ratio of direct solar radiation.

2.7 Converging field of efficiency

Year, by concentrating the field reflected or transmitted light into the heat sink and the mouth of the solar radiation incident on the condenser to the total field area lighting normal

The ratio of direct solar radiation.

2.8 Specular reflectance

Specular reflection of solar radiation flux ratio of solar radiation flux incident.

2.9 Cosine loss

Since the received energy of sunlight incident direction and the normal direction of the mirror are not parallel port lighting caused reduction.
