Photovoltaic array monitoring method and system

Abstract

The invention discloses a photovoltaic array monitoring method. The photovoltaic array monitoring method comprises the steps that a detection signal of a photovoltaic array is obtained through a sensor array; a Beidou satellite is utilized to send the detection signal to a monitoring terminal. Under the background that photovoltaic array signal communication can be achieved in remote high-altitudeand desert regions, the sensor array is utilized to obtain the detection signal, the number of used sensors is greatly decreased, the installing cost and use and maintenance costs are reduced, the operation is simpler, meanwhile richer detection information can be obtained, and the patrolling work amount of workers is decreased. In addition, the invention also discloses a photovoltaic array monitoring system. The photovoltaic array monitoring system has the advantages same as the monitoring method.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a monitoring method and a monitoring system for a photovoltaic array. Background technique [0002] Solar energy is a sustainable and non-polluting green and clean energy. In areas rich in solar energy resources, people have developed a variety of photovoltaic power generation systems to realize the collection and utilization of the sun. However, in practical applications, we can find that in order to obtain better solar energy collection effects, photovoltaic power generation systems are generally placed in remote high-altitude and desert areas. There are many inconveniences in traffic and harsh environments in this area. The staff's inspection, monitoring, exclusion (exclusion of abnormal conditions) and other work have brought many difficulties. Therefore, proposing a real-time monitoring terminal for fault location of photovoltaic arrays complies with the develop...

Problems solved by technology

Among them, the infrared image method has the disadvantages of low detection accuracy, high equipment cost, and poor real-time performance.

The diagnostic method based on electrical signals also has its own limitations, such as: too many sensors are used, the resolution of fault location is poor, and the detection structure is difficult to promote in large-scale photovoltaic array applications, etc.
