Heliostat tracking control device and tracking control method thereof

Abstract

The invention discloses a heliostat tracking control device and a tracking control method thereof, and the heliostat tracking control device comprises a remote control center, main controllers, transmission mechanisms, stepping motors and heliostat position feedback devices, wherein each heliostat position feedback device comprise an acceleration transducer and an absolute value encoder; each acceleration transducer is installed on the surface of a corresponding heliostat, and the absolute value encoder is installed on the output shaft of the corresponding transmission mechanism; the output end of each heliostat position feedback device is connected with the input end of the corresponding main controller; the remote control center is connected with each main controller; the output end of each main controller is connected with the input end of the corresponding stepping motor; and the input shaft and output shaft of each transmission mechanism are respectively connected with the output shaft of the corresponding stepping motor and the corresponding heliostat. By utilizing the heliostat tracking control device provided by the invention, the orbit of the sun can be accurately tracked, the sunlight is effectively reflected to a heat collector, and the solar heat utilization ratio is improved.

Description

technical field [0001] The invention specifically relates to a heliostat tracking control device and a tracking control method using the device. Background technique [0002] Energy is the cornerstone of the existence and development of modern society. With the continuous development of the global economy and society, energy consumption also continues to grow accordingly. As time goes by, the scarcity of fossil energy becomes more and more prominent, and this scarcity is gradually reflected in the price of energy commodities. In the context of the increasingly tense supply of fossil energy, the large-scale development and utilization of renewable energy has become an important part of the energy strategy of various countries in the future. [0003] Solar energy is an inexhaustible renewable energy for human beings. It has sufficient cleanliness, absolute safety, relative extensiveness, long life and maintenance-free, resource adequacy and potential economy. Etc. Theoreti...

Problems solved by technology

The disadvantage of this control is that the height angle encoder of the heliostat and the heliostat are not in the same axis, resulting in an error in the feedback of the height angle, and this error is different in different time periods of the day, coupled with the gravitational settlement of the steel plate, This error will be larger
