Abstract

The invention discloses provides a method of correcting a condensed light disk tracking system error and an apparatus thereof. The method is characterized by firstly calculating an error value of a theory displacement value and an actual displacement value at each same sampling time of a condensed light disk; and then, according to an average value of the error values, correcting the theory displacement value at current sampling time so that an error between the theory displacement value and the actual displacement value of the condensed light disk is reduced and the condensed light disk can accurately track the sun. Photoelectric conversion efficiency of a disk-type solar power generation system is increased.

Description

technical field [0001] The invention relates to the field of dish solar power generation, and more specifically relates to a method and device for correcting errors in the tracking system of a concentrating dish. Background technique [0002] Dish solar power generation is a way to use solar heat to generate electricity with high efficiency. It is a power generation system that uses a concentrator to gather sunlight to a fixed point, converts the thermal energy at that point into mechanical energy, and then uses a generator to convert the mechanical energy into electrical energy. How to ensure that the concentrating dish tracks the sun in real time is a problem that must be solved. At present, a spotting dish tracking system is usually used to adjust the current position of the spotting dish in real time, so as to realize the tracking of the sun by the spotting dish. [0003] The solar thermal power generation tracking system calculates the theoretical displacement value o...
