S380, start next tracking cycle；
Step S430, the real-time monitoring of environmental wind speed of air velocity transducer carried by system, judge whether work as actual wind speed
Reach preset strength；It is then return to step S370, otherwise into step S440；
Step S440, judge whether the true sun moment equals or exceeds the sunset time in step S330, i.e., whether very too
The positive moment >=sunset moment；It is to terminate to track, system stalls, otherwise return to step S370.
The utility model based on to the high conversion solar power system embodiment tracked day using batch (-type) tracking calculate
Method, acted once at interval of 30 minutes depending on the daily motion track following cycle, this is due to frequently opening for continous way tracing motor
Kinetic energy consumption is very big, and the power of electric motor starting moment is about more than four times of motor normal operation power, and frequently starting to make
Into larger power consumption, therefore the number of starts of motor is reduced, reached the purpose for reducing system energy consumption；Batch (-type) after improvement
Tracking control algorithm, and a kind of control method of open loop, belong to a kind of intelligent control algolithm of simplification.
Moreover, step S350 passes through the judgement to light intensity, if reaches the motor action threshold value of setting, when light is strong
Degree is less than rainy days during setting value, and system can be without tracking.
In addition, the utility model to the high conversion solar power system embodiment tracked day based on belonging to double-axis tracking
System, while track solar azimuth and elevation angle, both with dual-axis tracking system the advantages of, improve dual-axis tracking system again
The shortcomings that big cost high energy consumption of volume is big；And using regarding daily motion track following (i.e. time tracking) as one-level tracking mode, with
Photoelectric tracking realizes two level accurate tracking, i.e., used on the basis of depending on daily motion track following as two level tracking mode
Photoelectric tracking to solar panels carry out angle adjustment, solar incident ray is coincided with solar panels normal, can accurately with
The elevation angle of the track sun and azimuth；Blocked or during the weather conditions such as cloudy day when running into black clouds, because light intensity is too small, on photosensitive tube
Caused electric signal will be lower than the threshold value of setting, and system just jumps to regarding daily motion track following mode automatically, treat that weather takes a turn for the better
Jump out automatically afterwards, continue photoelectric tracking mode, ensure that and also can in rainy days or black clouds masking etc. under complicated weather condition
Normal work.
As shown by data after test of many times, system power dissipation≤50W, cost<0.5 yuan/watt, generated energy improve >=37%,
Carrying load ability >=2000N, no error starting and reset, and high wind automatically resets by mistake.Really there is low energy consumption, low cost, generating
Efficiency high, carrying load ability be strong, resets without error starting and by mistake and the advantages of high wind automatically resets, and delicate structure, small volume,
Double-axis tracking solar azimuth and elevation angle, operate steadily reliable, suitable for the solar power generation system in the range of 100-5000W
System, meet following development trend to day tracking solar power system, be suitable for large-scale promotion application.
It should be appreciated that the foregoing is only preferred embodiment of the present utility model, it e insufficient to limit this reality
With new technical scheme, for those of ordinary skills, within the spirit and principles of the utility model, Ke Yigen
Increased and decreased according to described above, replaced, converted or improved, and the technical side after all these increases and decreases, replacement, conversion or improvement
Case, it should all belong to the protection domain of the appended claims for the utility model.
