Problems solved by technology

[0003] Purpose of the invention: Aiming at the problem of constructing the routing of the status monitoring network of the photovoltaic power generation system, the present invention provides a method for constructing the routing of the monitoring network of the photovoltaic power generation system. The method combines the shape and size of the photovoltaic array and the deployment of nodes in the monitoring network to construct a hierarchical routing chain Road table, when the node fails, the effective nodes in the monitoring network will not be able to transmit data information due to the interruption of routing. The routing reconstruction method provided by the present invention enables the maximum number of routing links in the monitoring network to be rebuilt after replacing a small number of nodes. , to reduce the loss of data transmission

[0013] 1. Routing protocol for status monitoring network of photovoltaic power generation system

[0014] Directed Diffusion (DD) routing protocol is a data-centric, query-driven routing protocol, which can save energy by reducing the number of data relays. In the DD protocol, the nodes in the monitoring network keep the information of the neighbor nodes. When the sink node needs some information, the sink node sends query instructions to the surrounding nodes in the form of broadcast. If the in...

Abstract

The invention discloses a method for constructing condition monitoring network routing of a photovoltaic power generation system. A condition monitoring network of the photovoltaic power generation system is formed by wireless sensor nodes which are orderly arranged on a photovoltaic array. The method is applicable to construction of the condition monitoring network routing of the photovoltaic power generation system. In order to guarantee the effectiveness of data transmission of the monitoring network, firstly, a monitoring network routing protocol is provided and used for setting a monitoring network routing table, and then the routing constructing method based on the binary system particle swarm algorithm is provided. When data transmission of the monitoring network fails due to failure of the sensor nodes, a small number of nodes are replaced according to the method, and then the reconstructing number of the monitoring network routing is the maximum.

Description

technical field [0001] The invention relates to a routing construction method of a state monitoring network of a photovoltaic power generation system, that is, a routing construction method of a state monitoring network of a photovoltaic power generation system based on a wireless sensor network. Monitor network routing link reestablishment. Background technique [0002] The grid-connected operation of photovoltaic power generation systems is an important feature of modern power grids. However, its monitoring technology is not yet perfect, and it cannot achieve flexible and effective monitoring effects. Wireless sensor network is a low-complexity, low-power, low-cost wireless network technology. In view of the randomness and intermittent characteristics of photovoltaic power generation system, wireless sensor network provides a new idea for the construction of photovoltaic power generation system monitoring network. . Although the construction of monitoring network routing...
