Embedded solar photovoltaic module data monitoring device and method

Abstract

The invention belongs to the technical field of solar photovoltaic module detection, and specifically relates to a device and a method for monitoring data of embedded solar photovoltaic module data. The device comprises a data acquisition chip, a current sensor, a communication assembly, a temperature sensor, and a bluetooth interface. The data acquisition chip receives operational data of a solar photovoltaic module through the current sensor and the temperature sensor, and performs integral generating capacity calculation and hidden danger judgment according to the operational data. The operational data, the integral generating capacity, and hidden danger judgment results of the solar photovoltaic module are output through the communication assembly. The device uses an embedded microprocessor as the core, and combining with an internet of things technology, detects operating states of the photovoltaic module in real time, so as to realize intelligentized data acquisition and analysis, fault diagnosis, fault location, fault removing and alarm. The device and the method provide a simple solution for intelligentized and remote monitoring of a solar power station system.

Description

Technical field [0001] The invention belongs to the technical field of solar photovoltaic component detection, and specifically relates to an embedded solar photovoltaic component data monitoring device and method. Background technique [0002] The solar photovoltaic power generation system is composed of several independent solar photovoltaic power generation components (commonly known as solar photovoltaic panels) to form a basic string in series, and several strings are connected in parallel in the combiner box and then connected to the inverter. At present, the data monitoring of the solar photovoltaic power generation system is only realized by collecting the data in the combiner box. This data monitoring method has the following disadvantages: [0003] 1. Only the data of the solar photovoltaic string can be measured, but the working data of each photovoltaic module in the string cannot be measured; [0004] 2. When a photovoltaic component in the photovoltaic string fails, it...

AI Technical Summary

Problems solved by technology

[0003] 1. Only the data of solar photovoltaic strings can be measured, but the working data of each photovoltaic module in the string cannot be measured;

[0004] 2. When a photovoltaic module in the photovoltaic string fails, it is impossible to point out where the faulty component is, so maintenance personnel are required to find the fault point one by one on site;

[0005] 3. When a component in the component string fails, the faulty component cannot be automatically eliminated, and the string will not be able to continue to generate power due to a component failure, reducing the power generation efficiency

[0006] 4. Without intelligent statistical analysis function, it is impossible to analyze whether there are hidden dangers or abnormalities in the components in advance, and it is impossible to isolate and protect photovoltaic modules before hidden dangers evolve into failures, and give reminders and suggestions for maintenance and repair
