Abstract
The invention provides a photovoltaic assembly intelligent optimization device; each photovoltaic assembly is matched with a maximum power tracking module; the maximum power tracking module is configured with a wireless emission module; wireless reception modules are integratedly arranged in a far side, and connected with the internet, a computer or a mobile phone, so address information and maximum power output information of each photovoltaic assembly can be obtained through the internet. If lighting condition changes, each photovoltaic assembly cannot realize real time maximum power tracking output, and cannot be monitored in real time, thus bringing difficulties for operation and maintenance; the photovoltaic assembly intelligent optimization device can solve the said problems.
Description
Technical field
The present invention relates to a kind of photovoltaic module intelligent optimization system, the optimization of particularly a kind of photovoltaic module level collection MPPT maximum power point tracking and wireless transmit and reception and supervising device.
Background technology
At present in photovoltaic system field, MPPT maximum power point tracking is not also fine to photovoltaic module rank, and whether the power stage of every block photovoltaic module maximizes the output power directly having influence on same optical crosstalk photovoltaic assembly, and supervisory system does not accomplish photovoltaic module rank yet simultaneously; At present for distributed generation system, especially familial distribution of cases formula is exactly a black box for owner, so monitor photovoltaic module rank, the ruuning situation of every block photovoltaic module is very important to allow owner see in real time.This technology belongs to blank at home at present.
Summary of the invention
Technical matters of the present invention to provide one to carry out MPPT maximum power point tracking to photovoltaic module and tracing and monitoring information to be gone out by wireless transmit, and can to the novel device unifying to receive that transmits of all photovoltaic modulies.
Technical scheme of the present invention is, every block photovoltaic module is furnished with maximal power tracing module, maximal power tracing block configuration has wireless transmitter module, another concentrating a long way off is provided with wireless receiving module, wireless receiving module connects with internet, computing machine or mobile phone, by internet, obtain every address information of block photovoltaic module and the output information of peak power.
Described maximal power tracing module, that every block photovoltaic module in solar cell array is connected with voltage, electric current adopts sample circuit, voltage, electric current adopts sample information to deliver to microprocessor, microprocessor is by the electric current of process sampling, voltage, launched by wireless transmitter module, simultaneously, in micro-place, device judges photovoltaic module maximum power point position, production burst control signal PWM, deliver to IGBT drive circuit, pulse-modulated signal is delivered to DC/DC converter circuit by IGBT drive circuit, DC/DC converter circuit, according to the dutycycle of pulse-modulated signal, the impedance matching of adjustment load, make photovoltaic module Maximum Power Output.
Superior effect of the present invention is:
1) solve and change due to illumination condition, every block photovoltaic module can not the problem of maximal power tracing output in real time;
2) solve every block photovoltaic module can not monitor in real time, thus for operation maintenance bring difficulty problem.

Embodiment
Refer to shown in accompanying drawing 1,2,3, the every block photovoltaic module 1,10 of the present invention is furnished with maximal power tracing module 2, maximal power tracing module 2 is configured with wireless transmitter module 3, another concentrating a long way off is provided with wireless receiving module 6, wireless receiving module 6 connects with internet 7, computing machine 8 or mobile phone 7, by internet 7, obtain every address information of block photovoltaic module and the output information of peak power.
Described maximal power tracing module 2, that every block photovoltaic module 10 in solar cell array is connected with voltage, electric current adopts sample circuit 11, voltage, electric current adopts sample information to deliver to microprocessor 12, microprocessor 12 is by the electric current of process sampling, voltage, launched by wireless transmitter module 3, wireless transmitter module 3 adopts model SZ05-STD-SMA or SZ05-ADV-1 device, simultaneously, in micro-place, device 12 judges photovoltaic module maximum power point position, production burst control signal PWM, deliver to IGB driving circuit 14, pulse-modulated signal is delivered to DC/DC converter circuit 13 by IGB driving circuit 14, the object of driving circuit is to isolate and amplifies the pwm signal produced by micro-process (STR910F), this signal is enable enough to drive the conducting reliably of IGBT pipe and cut-off.The optocoupler TLP250 that this driving circuit adopts TOSHIBA company to produce realizes the isolation between strong, weak electricity.DC/DC converter circuit 13, as shown in Figure 4, according to the dutycycle of pulse-modulated signal PWM, the impedance matching of adjustment load 15, makes photovoltaic module 1,10 Maximum Power Output.
Because atmospheric environment or intensity of illumination change, photovoltaic cell
family curve also changes, and the position of maximum power point is not fixing.So-called MPPT maximum power point tracking, be exactly the moment adjustment dynamic characteristic slope (for resistive load), make it with
characteristic intersection point (overlaps with maximum power point all the time as best) all the time near the maximum power point of photovoltaic cell.For general load, MPPT maximum power point tracking is exactly the impedance of moment regulating load, makes the impedance that loaded impedance is corresponding with maximum power of photovoltaic cell point consistent, thus photovoltaic cell is operated on maximum power point.In brief, the principle that MPPT maximum power point tracking realizes is exactly impedance matching.
