Embodiment Construction

[0036] exist figure 2 In the implementation schematic diagram of controlling the synchronous tracking of the heliostat array, the precision sun tracker 9 works in the state of accurately tracking the sun, and controls the tracking drive motor of each heliostat in the heliostat array. Due to the relative motion of the sun, when the deviation error of the incident light from the sun exceeds the allowable value, the precision sun tracker 9 starts the tracking drive motor of itself and each heliostat in the heliostat matrix to correct the deviation error of the incident light from the sun, When the deviation error of the sun's incident light is eliminated, the precision sun tracker closes itself and the tracking drive motor of each heliostat in the heliostat array stops rotating, and completes a control cycle. When the sun's incident light deviation error occurs next time, the above control process is repeated to realize the synchronous tracking of the controlled heliostat array....

Abstract

In the invention, employing a sun tracker follows the sun. The drive motor of the sun tracker and a heliostat uses the same synchronous micromotor driven by a common-frequency power supply and the synchronous micromotor can run and stop at the same time. The reduction rate of the speed reducer of the sun tracker is 1:N and the reduction rate of the speed reducer of the heliostat is 1:2N. Provided that the sun tracker follows the sun, the whole heliostat in the array offset following the tracked sun to make the reflected light point to the fixed target.

Description

technical field [0001] The invention belongs to the field of solar energy applications, and in particular relates to a control method for synchronous tracking of numerous heliostats in a solar tower thermal power generation system and a solar tower heat collection system. Background technique [0002] At present, the heliostat is composed of four parts: plane reflector, mirror frame, tracking mechanism and control system. Heliostat technology is the key technology of tower solar thermal utilization system, which can realize tower solar thermal power generation system, tower solar thermal Boiler and tower solar thermal evaporation seawater desalination system realize the heat utilization of high temperature solar energy. [0003] The function of the heliostat is to reflect the incident sunlight to a fixed target. Many heliostats form a heliostat array to reflect the sunlight to a fixed target to obtain focused solar energy. Due to the relative motion of the sun, heliostat tr...
