Description
Technical field
The utility model belongs to the research of photovoltaic power station monitoring system, relates in particular to a kind of automatic tracking type photovoltaic power station monitoring system.
Background technology
The energy is the driving force of social prosperity and development, and all human activities all be unable to do without it.The average growth rate of current population is constantly exerted pressure to the demand of the energy.Non-renewable resources such as coal, oil, rock gas are the main energy sources of present human social development, the finiteness of resource and people become increasingly conspicuous to the contradiction between the quick demand that increases of resource, cause energy prices constantly to raise, cause the global economy fluctuation, the factor leading to social instability of society increases.After the oil shock of 1973 crisis, people are seeking the development of new energy technology always.The utilization of regenerative resources such as sun power, water energy, wind energy, tide energy, biological energy source is generally had an optimistic view of.Wherein sun power is most important clean energy resource, and from the forming process analysis of energy, the energy of other form that exists on the earth is nearly all come from conversion of solar energy.The sun power cleaning is pollution-free, aboundresources, is acknowledged as the new forms of energy mouth of the most effective replacement fossil energy.
Photovoltaic generation is a kind of by sun power directly being converted to the forms of electricity generation of electric energy, mainly is to change by solar photocell.In common solar photovoltaic generation system, adopt the design of fixed type photovoltaic plate mostly, can not guarantee that photovoltaic panel becomes to become all the time an angle of 90 degrees with the sunshine angle, solar energy utilization rate is abundant inadequately; Owing to the singularity of sun power distribution, photo-voltaic power generation station generally all is distributed in scarcely populated remote districts again.
The utility model content
The purpose of this utility model is that design one cover can improve the generating efficiency of photo-voltaic power generation station effectively, and carries out the remote on-line monitoring system.
To achieve these goals, the utility model relates to a kind of automatic tracking type photovoltaic power station monitoring system, and simplified summary is: native system mainly is made up of light signal transmitter, photovoltaic power generation apparatus, Zigbee/GPRS gateway and remote monitoring center.System passes to the Zigbee/GPRS gateway by the light signal that the light signal transmitter obtains, by the Zigbee/GPRS gateway data are distributed to photovoltaic power generation apparatus then, at last, the running parameter of collecting each photovoltaic power generation apparatus by the Zigbee network in the Zigbee/GPRS gateway and serial network and the running parameter of light signal transmitter, and by GPRS network it is fed back to remote monitoring center.
The integrated solar automatic tracking rotation platform of described light signal transmitter and automatic tracking controller, its function is to adjust the anglec of rotation of horizontal longitudinal axis stepper motor by the track of sun moving law of locality and clock information, detect sunlight intensity information in real time, and the sunshine angle information of the interior sunlight intensity maximum point of preservation rotating range, with its pilot angle as each photovoltaic power generation apparatus.
Described Zigbee/GPRS gateway is integrated Zigbee coordinator module, GPRS module and serial communication module are the communication centers of system.
Native system adopts automatic track algorithm according to the difference of photovoltaic cell output voltage, divides dual mode to control:
1. when light intensity＜=intensity threshold:
1) the system synchronization time, the query time table arranges the motor initial position;
2) transmitters sense light intensity, record data and distribution;
3) each photovoltaic power generation apparatus receives data and judges whether light intensity greater than before, if greater than, then adjust angle; Otherwise, then be failure to actuate, continue to wait for to receive.
4) transmitter moves and detects light intensity as per the schedule successively;
5) detect termination signal, each equipment that resets is to selecting initial value.
2. when light intensity＞intensity threshold:
1) the system synchronization time, query time becomes, and the motor initial position is set;
2) transmitters sense light intensity, and record data;
3) after the time interval arrived, transmitter transverse axis stepper motor was with interval rotation 0～180 degree angle of (0～90) degree, and after each transverse axis rotation finished, the transmitter longitudinal axis advanced motor with interval rotation ± 15 degree angles of 0～15 degree, and recording light intensity and angle;
4) from all data that the step 3) operation is recorded, select maximum light intensity and corresponding angle-data, be distributed to all photovoltaic generation equipment.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are:
Native system is with the network technology that Zigbee combines with GPRS, and it is special to have solved general photo-voltaic power generation station Regional Distribution, and monitoring difficulty and wiring be problem such as aging easily, has realized photovoltaic generating system low cost, low-power consumption and high maintainable real-time monitoring.
With the independent independent detection of carrying out light signal information of light signal transmitter, and send to photovoltaic power generation apparatus by the unification of Zigbee network and carry out solar automatic tracking, solved neatly when solar automatic tracking is carried out in the large-scale photovoltaic power house and need consume a large amount of energy and cost problem.
