Abstract
The invention discloses an intelligent junction box which is mainly applied to a solar power generation system to monitor a solar module. If the solar module is damaged or shielded and the like, power generation capacity of the whole solar array can be influenced, and currently, the solar power generation system is short of an effective mechanism to monitor the solar module. The intelligent junction box is characterized in that a detection module and a communication module are added inside the junction box, output voltage and output current of the solar module and temperature inside the junction box are measured through the detection module, measured data are uploaded to an intelligent monitor by the communication module by means of power line carrier communication, and the intelligent monitor uploads the data to a monitoring website server through a network to realize rear-time monitoring and management of the solar module.
Description
Technical field
The present invention relates to power electronic technology, power-line carrier communication, heliotechnics, solar energy generation technology, be applied to solar grid-connected and generate electricity from net.
Background technology
At present solar power generation is mainly with after a plurality of solar module connection in series-parallel, then is connected with solar inverter and realizes being incorporated into the power networks or generating electricity from net.
Solar power station especially solar module is easy to break down, and the reason of fault may be that solar module is infected with dust, pollen, birds droppings, accumulated snow, might be also defective mounting, production defective etc.
Because solar module is cascaded, the maximum current that flows through in the string group depends on the solar module that performance is the poorest.The solar module of defectiveness or damage makes the same variation of other solar module performance that works in this string group.So, the operation conditions of judgement solar power station and the solar module of searching the generation problem among a large amount of solar modules, for the fault of timely eliminating solar power station, the generating efficiency that improves solar power station seems extremely important.In this respect, lack at present a kind of simply, effectively, scheme realizes cheaply.
Summary of the invention
For the problems referred to above, main purpose of the present invention is to provide a kind of simple installation, Intelligent wiring box (201) cheaply, Intelligent wiring box (201) inside has increased detection module (104) and communication module (105), utilize existing cable to transmit data in the power line carrier communication mode, not needing increases the extra communications cable, and existing solar power system is fully compatible.digital signal controller (103) is controlled detection module (104) to the output voltage of solar module (101), electric current detects, and the internal temperature of solar junction box is detected, when Intelligent wiring box (201) receives the uploading data instruction that intelligent monitor (207) sends, the sequence number of these measurement data and solar module (101) together by communication module (105) in the power line carrier communication mode through header box (202), DC power distribution cabinet (203), by inverter (204) relaying, be sent to intelligent monitor (207), intelligent monitor (207) again by router (208) from network (209) with data upload to monitoring network site server (210), monitoring network site server (210) is according to the voltage of solar module (101), electric current, temperature judges whether it is working properly.If data are undesired, produce alarm, the attendant can remove to check and safeguard solar module (101) according to alarm.
Description of drawings
