Description
Technical field
The utility model belongs to technical field of photovoltaic power generation, specifically relates to a kind of polar mounts photovoltaic power generation apparatus.
Background technology
In fact geographic latitude is equivalent to the line in certain any same the earth's core (center of circle) on the earth, and the angle between equator; Sun altitude, is in fact equivalent to sunray (supposing that sunray is directional light) with the angle between excessively local disc tangent line (horizon); Direct sunlight line is perpendicular to earth surface (disc), so the inevitable vertically horizontal line of direct projection light, and the extended line of direct sunlight line must cross the earth's core.Usually we represent somewhere height of the sun at noon with h, and it is numerically equal to the altitude of the sun in the coordinate system of celestial horizon.Sun altitude along with local time and the sun declination change and change.Solar declination represents with δ, and observation ground geographic latitude φ represents, local time (hour angle) represent there is the computing formula of sun altitude with t: sinh=sin φ sin δ+sin φ cos δ cost.Day rise sunset, in same place one day, sun altitude is constantly change.During sunrise sunset, angle is all zero degree, and during high noon, sun altitude is maximum.Because local time t=0 when high noon, so sun altitude when high noon can use following formulae discovery: for the Northern Hemisphere, H=90 °-(φ-δ); For the Southern Hemisphere, H=90 °-(δ-φ).Summer solstice, the sun direct projection tropic of cancer, i.e. north latitude 23.5 degree; The winter solstice sun direct projection tropic of Capricorn, i.e. 23.5 degree, south latitude.Mesophase spherule is every 47 latitudes, and half a year is 365.26/2=182.63 days.From Winter Solstice in the Summer Solstice, subsolar point moves southwards from north latitude 23.5 degree, move 47/182.63=0.2574 latitude every day, after half a year, namely the winter solstice moves on to 23.5 degree, south latitude, then northwards put again, same with the speed of 0.2574 latitude every day, through 182.63 days, namely the summer solstice got back to north latitude 23.5 degree.The latitude of subsolar point every day very accurately can be found, i.e. solar declination δ by this.
In this case, when we adopt solar declination and pole axis to follow the tracks of track of sun, significantly, the excursion of solar declination is very little, namely the motion frequency in this direction and motion amplitude less, therefore very energy-conservation; But existing tracking mode often only adopts uniterminal axis or traditional double-axis tracking, and it does not possess power saving function.
