Solar energy sun chasing and state monitoring system and method thereof

Abstract

The invention discloses a solar energy sun chasing and state monitoring system and a method thereof. According to the system, an upper computer is used as a control center; an astronomical calendar theory expansion formula is used to calculate an azimuth angle and a height angle of the sun. Then, an error caused by atmospheric refraction and an altitude is corrected, a horizontal angle and a pitch angle of a power generation plate are calculated and are transmitted to each tracking transmission mechanism so that sun chasing motion is executed. Simultaneously, software acquires local weather phenomena through a network, such as a cloudy sky, rain, snow, wind and other information, complements on-site illumination and a wind power detection result, and sends instructions of protection, stopping, starting, tracking and the like to a sun chasing control device. The system has the advantages that concentration control is used; cost is low; an anti-interference performance is strong and a tracking error is small.

Description

technical field [0001] The invention belongs to the technical field of meteorology, and relates to a solar tracking and state monitoring system and method, in particular to a solar tracking and state monitoring system and method based on network weather forecast and astronomical almanac algorithm. Background technique [0002] The current solar tracking systems are roughly divided into three categories. The first category uses photosensitive devices to sense the sun’s azimuth to drive the motor to track the sun; the second category uses the astronomical calendar to calculate the sun’s azimuth, and drives the power generation panel to rotate to a certain horizontal angle and elevation angle at regular intervals. The third category is the combination of the first two categories, that is, calculate first and then fine-tune. However, these three types of technical solutions are all realized by embedded devices. Each solar power generation device needs to be equipped with a solar...

Problems solved by technology

However, these three types of technical solutions are all realized by embedded devices. Each solar power generation device needs to be equipped with a solar tracking control mechanism (computing unit) and a solar tracking transmission device (executive unit). For the entire power plant, All belong to decentralized control, the first type of anti-interference is too poor, clouds, dust, etc. may cause system misjudgment

The second category is that the accuracy of floating-point calculations in the single-chip microcomputer chip is limited, resulting in a large error in tracking the sun, and it cannot respond to weather information.

The third type combines the first type of scheme with the second type of scheme, which has higher accuracy, but increases the cost. Similarly, it cannot respond to severe weather such as strong winds in time
