Application of IoT in power transmission line monitoring

Abstract

Nowaday in Vietnam, the verification and maintenance of 220kV - 500kV transmission lines is mainly done by manual labor. However, this task is quite hard, the workers have many difficulties such as the long moving distance (hundreds of kilometers) through many areas of complex terrain to verify the data and prevent the widespread problems. The efficiency and quality of line check also depends on the enthusiasm and experience of the workers. The demand to develop the power grid is constantly increasing to release full capacity from solar power plants, wind power plants, making the line always operating in overload state. Some problems are caused by the rapid growth of plants violating high voltage transmission line safety distances.Therefore, an online transmission line monitoring system will be a useful tool for improving the line operation and reduce the pressure for workers. In this paper, the application of the wireless data transmission platform and LABVIEW programming software to build a system for online data collection of lines, program settings, applications on mobile devices. Dynamic monitoring of lines over the Internet reduces the workload of workers.
