On-line fault monitoring method of photovoltaic module

Abstract

The invention discloses an on-line fault monitoring method of a photovoltaic module. The method comprises the steps of controlling a positioning module to position the photovoltaic module so as to acquire position information of the photovoltaic module; controlling a temperature sensor to obtain a temperature value of the positioned photovoltaic module; comparing the temperature value of the positioned photovoltaic module with a preset temperature value; controlling a visible light camera to shoot and record the photovoltaic module to acquire picture and video of a fault photovoltaic module ifthe temperature value of the positioned photovoltaic module is larger than the preset temperature value, otherwise controlling the positioning module to position a next photovoltaic module, and returning to the step of controlling the temperature sensor to acquire the temperature value of the positioned photovoltaic module; and controlling a wireless communication module to send the picture, thevideo and the position information of the fault photovoltaic module to a communication base station. According to the on-line fault monitoring method of the photovoltaic module, a worker can be convenient to timely acquire various types of information of the fault photovoltaic module, and high-efficiency and accurate monitoring of the fault photovoltaic module is facilitated.

Description

technical field [0001] The invention relates to the technical field of fault monitoring, in particular to an online fault monitoring method for photovoltaic modules. Background technique [0002] In recent years, distributed photovoltaic technology, as an emerging energy technology, can simultaneously meet energy demand, reduce the greenhouse effect and improve power supply reliability, and is an important direction for the development of energy technology in the future world. With the vigorous development of the photovoltaic industry, monitoring the photovoltaic power station system can not only detect and solve faults in time, but also reduce maintenance costs. [0003] In the early days, the monitoring method of solar photovoltaic power plants was manual inspection with low efficiency. The traditional photovoltaic module fault diagnosis method is to set up an infrared imager in front of the photovoltaic array, extract fault features through infrared image processing to i...

[0003] In the early days, the monitoring method of solar photovoltaic power plants was manual inspection with low efficiency

The traditional photovoltaic module fault diagnosis method is to set up an infrared imager in front of the photovoltaic array, extract fault features through infrared image processing to identify faulty battery components, and require a large number of hardware devices such as infrared cameras, which consume a lot of manpower and material resources

Existing photovoltaic module fault monitoring methods are difficult to ensure efficient and accurate monitoring of faulty components
