Research On Application Scheme Of Fusion Communication Technology In Power Line Monitoring

As one of the important links of national economic development,the security and reliability of power transmission and the stability of the power grid are the most important part of the power industry.With the development of information technology,smart grid technology is also constantly developing.The technology of monitoring transmission lines and diagnosing is used to the production process.The online monitoring of transmission lines is the key part to realize the smart grid.With monitoring technology,the status of the transmission network are collected in real time.Then the data is transmitted to the back-end server.The server can judge whether the current transmission lines are normal or not,mainly according to the relationship between the current status and the normal status.Therefore,for smart grid,the demand for data transmission and communication is growing.At present,the data transmission scheme of smart grid in our country is mainly based on public network or optical fiber communication.But the coverage,signal stability,deployment cost and other aspects have defects.According to a large number of practical applications,it has been proved that a single communication technology is unable to meet the needs of power line monitoring system.At the same time,with the continuous development of intelligent power monitoring business in China,this traditional data transmission networking has been unable to meet the requirements of business development.Meanwhile,the need for reconfiguration of communication mode has become stronger and stronger.Fusion communication technology is becoming an inevitable choice in monitoring system.Based on the study of the composition and characteristics of power line monitoring system,this paper designs a communication technology.This technology is more suitable for the data transmission scenario of modern power line monitoring.We compared the characteristics of different communication technologies,such as optical fiber communication,proprietary network communication,wireless communication,satellite communication and so on.And finally determines the use of wireless network transmission and OPGW data transmission mutual.The combination of communication methods to form a network is studied,and then realize the technical way of integrated communication.At the same time,the key nodes,hardware equipment and power supply of the system are designed.Including power supply scheme of monitoring sensor equipment,power supply scheme of optical fiber connector and power supply scheme of tower top.Different power supply schemes are designed for different locations and different equipment to achieve appropriate power supply mode.Finally,the design of integrated communication networking mode will be tested in the actual scenario.The experimental results and system simulation results confirm that the integrated communication technology of the system design can effectively guarantee the data transmission in power line monitoring.Compared with the single communication technology used in the current application,more stable,clearer and more real-time monitoring data can be seen from the back-end monitoring interface.This system provides a more reliable and low-cost analysis for the large data of power monitoring.So the application technology designed in this paper has a certain practical value.
