A kind of photovoltaic battery panel on-line detecting system
Technical field
The present invention relates to technical field of photovoltaic power generation, particularly relate to a kind of photovoltaic battery panel on-line detecting system.
Background technology
Along with photovoltaic solar generation technology reaches its maturity, photovoltaic cell board component starts to use in a large number at industrial circle.At present, assembly producer all using the emphasis how lifting subassembly photoelectric conversion efficiency is studied as it, develops the photovoltaic cell board component of the various materials such as polysilicon, monocrystalline silicon, film.In addition, assembly producer also considers from the angle of assembly, has carried out some researchs with regard to how improving components availability, how improving assembly reliability and how carrying out the aspects such as component matching.But, these researchs are all static, carry out static measurement for each block assembly dispatched from the factory, the assembly that screening component characteristic is relatively consistent, mark levels, carry out component matching according to the principle of same levels assembly composition assembly square formation, reduce mismatch effects, reach the object of raising efficiency.But in the power station of reality uses, owing to blocking, the factor such as accidental damage and long-term work loss all can cause assembly to occur new inconsistent phenomenon, component mismatch will the generating efficiency in the whole power station of impact.
Summary of the invention
The object of the invention is to, by a kind of photovoltaic battery panel on-line detecting system, solve the problem that above background technology part is mentioned.
For reaching this object, the present invention by the following technical solutions:
A kind of photovoltaic battery panel on-line detecting system, it comprises data acquisition module, data transmission module and data processing centre; Described data acquisition module is connected with data transmission module, for the status data of online acquisition assembly, and send to data processing centre by data transmission module, wherein, described status data comprises but is not limited to the electric current of the real-time voltage of monoblock battery board component, cell panel backboard temperature, this group string; Described data processing centre is connected with data transmission module, for receiving the status data of the assembly that data transmission module sends, to this data analysis, judge power station running status whether assembly whether mismatch in abnormal, power station, and return corresponding revision directive to data transmission module.
Especially, described data acquisition module is arranged at the back side of monoblock battery plate.
Especially, described data acquisition module is integrated in the terminal box of assembly.
Especially, described data acquisition module and data transmission module are integrated device.
Especially, described data transmission module can select wireless or wired either type to carry out transfer of data.
The photovoltaic battery panel on-line detecting system that the present invention proposes can gather the status data of each block assembly by real-time online, and send to data processing centre to analyze by data transmission module, judge power station running status whether assembly whether mismatch in abnormal, power station in time, and return corresponding revision directive in time, guarantee the healthy and stable operation in power station.Advantage of the present invention is as follows: one, achieve the characterisitic parameter Real-Time Monitoring to each block battery panel components, finds the operating problem in power station in real time in conjunction with data analysis; Two, for large data provide support, for the Intelligent Power Station successful operation such as power station O&M, life cycle management provide possibility; Three, each block battery panel components in power station can be reviewed, its usefulness of maximized performance; Four, realize simply, with low cost, accessible site, in battery panel components, can add at the different times of power plant construction.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not full content, unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present invention understand usually.The object of term used herein just in order to describe specific embodiment, is not intended to be restriction the present invention.
Please refer to shown in Fig. 1, the photovoltaic battery panel on-line detecting system structural representation that Fig. 1 provides for the embodiment of the present invention.
In the present embodiment, photovoltaic battery panel on-line detecting system specifically comprises data acquisition module 101, data transmission module 102 and data processing centre 103.Described data acquisition module 101 is connected with data transmission module 102, for the status data of online acquisition assembly 104, and send to data processing centre 103 by data transmission module 102, wherein, described status data comprises but is not limited to the electric current of the real-time voltage of monoblock battery board component 104, cell panel backboard temperature, this group string.Described data processing centre 103 is connected with data transmission module 102, for receiving the status data of the assembly 104 that data transmission module 102 sends, to this data analysis, judge power station running status whether assembly 104 whether mismatch in abnormal, power station, and return corresponding revision directive to data transmission module 102.
In the present embodiment, data acquisition module 101 can be arranged at the back side of monoblock battery plate or be integrated in the terminal box 105 of assembly 104, and also can be positioned over other places of assembly 104, each detection limit physics independently can be placed and also can put together.Described data acquisition module 101 can independently separate with data transmission module 102, and also can become one device.Described data transmission module 102 can select wireless or wired either type to carry out transfer of data.
Technical scheme of the present invention can gather the status data of each block assembly by real-time online, and send to data processing centre to analyze by data transmission module, judge power station running status whether assembly whether mismatch in abnormal, power station in time, and return corresponding revision directive in time, guarantee the healthy and stable operation in power station.Advantage of the present invention is as follows: one, achieve the characterisitic parameter Real-Time Monitoring to each block battery panel components, finds the operating problem in power station in real time in conjunction with data analysis; Two, for large data provide support, for the Intelligent Power Station successful operation such as power station O&M, life cycle management provide possibility; Three, each block battery panel components in power station can be reviewed, its usefulness of maximized performance; Four, realize simply, with low cost, accessible site, in battery panel components, can add at the different times of power plant construction.
Note, above are only preferred embodiment of the present invention and institute's application technology principle.Skilled person in the art will appreciate that and the invention is not restricted to specific embodiment described here, various obvious change can be carried out for a person skilled in the art, readjust and substitute and can not protection scope of the present invention be departed from.Therefore, although be described in further detail invention has been by above embodiment, the present invention is not limited only to above embodiment, when not departing from the present invention's design, can also comprise other Equivalent embodiments more, and scope of the present invention is determined by appended right.
