The Design Of Wireless Sensor Network For Power Tower

The wireless sensor network is composed of a large number of sensor nodes placed in the measurement area.These miniature,small sensor nodes in addition to the basic sensing function,but also through the self-organization to form a multi-hop wireless network system.In recent years,with the continuous development of sensor and communication technology,wireless sensor network from the beginning of the military,engineering and other large projects,has gradually moved towards the ordinary people's ordinary life.Among them,the wireless sensor network in the application of modern power grid as a focus more and more people's attention.Modern grid,also known as smart grid,is a new trend in power grid development.It improves the efficiency,reliability and sustainability of the grid and enables rapid and accurate positioning of the failed areas.At the same time,it can alleviate the supply pressure by interacting with the user and reducing the growing environmental pollution by introducing renewable energy.However,the implementation of smart grid requires a lot of technical support,including advanced information and sensing technology in the realization of automatic control of the power grid is particularly critical.Through the massive sensor monitoring information feedback,the grid can be based on different situations to make rapid response,to provide users with more comprehensive information and services.Through the use of wireless sensor technology,just to meet the needs of smart grid.At present,China's research on smart grid is mainly focused on long-distance power transmission line information monitoring and analysis.Due to the huge land area in China,some long-distance power transmission lines in the desert,gobi,glaciers and other harsh areas,so how to these long-distance power transmission lines and the situation around the line in real-time comprehensive monitoring and timely response,China's research focus on smart grid.For the existing long-distance power transmission line monitoring system in China,the following shortcomings and the need to improve the aspects:1)for long-distance transmission lines in the power tower of the overall information monitoring is not comprehensive,due to the sensor module and power tower monitoring and control system 2)The existing power tower monitoring and control system due to the integration of power supply,sensing,communication and other modules,resulting in the volume is too large,difficult to construction of the shortcomings of the sensor module monitoring and control system.In this paper,the research on the long-distance power transmission line of the smart grid is different from the traditional research in that the research of the wireless sensor network is concentrated on the power tower of the long-distance power transmission line of the smart grid in the range of one hundred meters.In this area,a wireless sensor network with a single power tower as the center is built.The sensor in the wireless sensor network contains the sensors in the range of 100 meters around the power tower and the power tower.In the wireless sensor network,select a superior performance wireless sensor as a gateway node,for the power tower wireless sensor network to collect the monitoring information,and with the adjacent power tower wireless sensor network gateway node data communication The Finally,the wireless sensor network design a safe and reliable communication protocol.By constructing the power tower wireless sensor network,this paper divides the long distance power transmission line of the smart grid into several small wireless sensor networks with single power tower.So that the long-distance power transmission line monitoring can be allocated to the power tower wireless sensor network,and finally a number of power tower wireless sensor network to monitor the data to the data center of the summary,so you can avoid monitoring the data collection process Chaos disorder,making the monitoring data collection process simple and efficient.Another advantage of building a power tower wireless sensor network is that when the sensor node is attacked and destroyed by an attacker,the problem can be controlled in a wireless sensor network with a single tower as the center,preventing the problem from continuing to the entire smart grid To spread,and the control center can quickly locate the fault and study the solution.The communication protocol is divided into an initialization process,a key distribution process,and a data upload process.By simulating the assumption of attack and the occurrence of the fault,the security of the uploading process from the construction of the communication model to the final monitoring data is verified.It is proved that the construction of power tower communication model can reduce the energy consumption and time delay of monitoring data collection by analyzing and comparing the energy consumption and delay in the construction of power tower communication model and non-construction communication model.It is proved that the construction of power tower communication model is predominant.
