摘要

This paper establishes the heliostat tracking model, and analyzes two error factors of mirror center offset and tilt of the base of the ideal heliostat model that exists in the actual work. The heliostat system based on the studied error and non-error compensation is applied to the simulation experiment platform of large-scale thermal power plant. The results show that the system eliminates errors to a large extent and improves the daily accuracy. This study significantly improves the installation efficiency and thermal power generation efficiency of heliostat array field in large-scale solar thermal power plant and reduces the cost of thermal power generation, which has a positive meaning in promoting the development of solar thermal power generation.
