Embodiment Construction

[0010] in the attached figure 1 Among them, the intelligent junction box (201) obtains power from the solar cell assembly (101), generates a stable DC voltage, and supplies power to the digital signal controller (103), the detection module (104), and the communication module (105).

[0011] In extreme cases, when the solar cell module (101) is completely covered, the auxiliary power supply (102) cannot generate a stable voltage from the solar cell module (101), and other modules will not work properly, and there is no signal sent to the monitoring The website server (210), while other surrounding solar battery components (101) are working normally at the same time, the system can determine that the solar battery component (101) is in an abnormal working state.

[0012] The digital signal controller (103) controls the detection module (104) and the communication module (105).

[0013] The input end of the detection module (104) is connected to the output end of the solar cell ...

Abstract

The invention discloses an intelligent component which is mainly applied to a solar power generation system to monitor a solar battery component. When the solar battery component is damaged or shielded and the like, electric energy production of a whole solar array is influenced, and at present, the solar power generation system is in lack of an effective mechanism to monitor the solar component. According to the intelligent component, a traditional solar connecting box corresponding to the solar battery component is replaced by an intelligent connecting box, a detection module and a communication module are additionally arranged inside the traditional connecting box, output voltage, output current and temperature inside the connecting box of the solar battery component are measured through the detection module, measurement data is uploaded to an intelligent monitor through the communication module through the method of power line carrier communication, and then the intelligent monitor uploads the data through the network to a monitoring website server so as to realize real-time monitoring and real-time managing to the solar battery component.

Description

technical field [0001] The invention relates to power electronics technology, power line carrier communication technology, solar technology, solar power generation technology, and is applied to solar power grid-connected and off-grid power generation. Background technique [0002] At present, solar power generation is mainly to connect multiple solar cell modules in series and parallel, and then connect them to solar inverters to realize grid-connected or off-grid power generation. [0003] Solar power plants, especially solar cell components, are prone to failure. The cause of failure may be that the solar cell components are contaminated with dust, pollen, bird droppings, snow, or it may be due to installation defects, production defects, and so on. [0004] Because the solar modules are connected in series, the maximum current flowing in the string depends on the solar module with the worst performance. A defective or damaged solar cell module will also degrade the perfo...
