Embodiment

[0069] A clustering and data sensing method applied to wireless sensors in photovoltaic power plants, the method is divided into the following steps:

[0070] Step A. Establish a clustering model:

[0071] Combining the Sierpinski triangle with the hexagonal cellular topology to establish a new ideal clustering model proceeds as follows:

[0072] (1) The entire area presents a regular hexagon, consisting of several regular triangles. There are a total of N nodes and a sink node. N sensors are randomly and evenly distributed in all regular triangle areas, ignoring the edge irregular areas.

[0073] The area of ​​the above-mentioned regular triangle is used to determine the size of the cluster, that is, to determine the size of the node N. The calculation method of the area of ​​the regular triangle is as follows:

[0074] Assuming that the side length of the equilateral triangle is R, the area of ​​the equilateral triangle is

[0075] Let the node distribution density be λ,...

Abstract

The invention discloses a clustering and data sensing method applied to a wireless sensor of a photovoltaic power station, belongs to the technical field of electric power Internet of Things information sensing, and aims to solve the problem that a photovoltaic power station monitoring system constructed based on a wireless sensor network cannot satisfy acquisition sensing and rapid and accurate processing of a large amount of data. The method comprises two steps of establishing a clustering model and determining an intra-cluster perception data collection scheme. The model established by the invention is applied to photovoltaic power station sensor network topology, can effectively solve the problem of network load energy consumption, has the advantages of fault-tolerant capability, load balance and the like, can balance the network load and save energy consumption, and ensures that photovoltaic power station information is quickly and efficiently sensed, and in processing and application of photovoltaic power station actual data, the effectiveness and the definiteness of the advantages of the method are verified.

Description

technical field [0001] The invention belongs to the technical field of electric power Internet of things information perception, and specifically relates to a clustering and data perception method applied to wireless sensors of photovoltaic power stations. Background technique [0002] At present, many photovoltaic power station monitoring systems are constructed based on wireless sensor networks, which enables extensive interaction of various links in the photovoltaic power generation system and improves the scheduling and operation level of photovoltaic power generation. However, due to the limited resources and geographical environment of photovoltaic power plants, many difficulties have been encountered in terms of deployment scale and lifespan, which have greatly affected its data collection perception and fast and accurate processing of large amounts of data, and at the same time caused blockage of transmission channels. Bring challenges to information transmission and...
