Problems solved by technology
[0005] At present, the precision error of the mirror tracking system in the solar thermal power generation system is mainly caused by the frame manufacturing error, installation error and tracking system error, which affects the optical focus offset of the mirror, resulting in uneven focal spot size and energy distribution. In severe cases, it will cause damage to the collector
[0006] However, in the prior art, there is no special equipment for detecting the accuracy of the tracking system of the solar thermal power generation mirror, so it is impossible to judge the accuracy of the tracking accuracy

Description
technical field [0001] The invention relates to the field of tracking systems for solar thermal power generation, in particular to a precision detection device for tracking systems for solar thermal power generation. In addition, the present invention also relates to a solar thermal power generation tracking system comprising the above precision detection device. Background technique [0002] As the earth's resources become increasingly scarce, and at the same time, people's awareness of environmental protection increases, the use of solar energy has become more and more extensive. [0003] The precision error of the solar thermal power generation mirror tracking system is an important indicator of system performance. In order to obtain high temperature and maximize the thermal efficiency, the precision of the tracking system is generally set higher. If the tracking precision is poor, the system performance may be poor, which will lead to The loss of intercepted solar energ...
