Abstract

The invention discloses a wireless sensor network device of a photovoltaic power station, which relates to the technical field of solar photovoltaic power stations, and comprises a network coordinator, a plurality of routing nodes, a plurality of module sensor nodes and an environmental sensor node. The device transfers information of various photovoltaic components to the routing nodes from the module sensor nodes, makes the routing nodes collected to the network coordinator, and also transfers environmental information acquired by the environmental sensor node to the network coordinator through the routing nodes at the same time, and then the network coordinator realizes an interface between data information and the internet; people can promptly know work and environmental information of the photovoltaic components, and can accurately diagnose and position by performing real-time detection, history storage, statistics and analysis on the characteristics of the photovoltaic components to prevent the further enlargement of faults and improve the power supply reliability and power supply quality of photovoltaic power stations; and the device improves the accuracy and anti-jamming capability of the photovoltaic power stations, and realizes the ultralow power consumption and stable work of the photovoltaic power stations.

Description

technical field

[0001] The invention relates to the technical field of solar photovoltaic power plants, in particular to a wireless sensor network system for photovoltaic power plants. Background technique

[0002] With the application of photovoltaic power generation technology more and more widely, a large number of photovoltaic systems have been put into operation. During the operation of the solar photovoltaic array, the partial failure of the standard rectangular battery panel, especially the open circuit, short circuit or performance degradation of the battery panel, will cause a significant drop in the output voltage or power of the entire power supply system. In severe cases, a chain reaction will occur, thereby destroying the work of the entire system. In practical applications, due to the module packaging process and other reasons, after eight to ten years of operation of the photovoltaic module, local areas will age due to the infiltration or diffusion of pores, ...
