Reliability Enhancement of Public Wireless Communication for Remote Control Services in Power Distribution in Smart Grid

Public wireless network has been widely utilized in power distribution communication due to its benefits of ease deployment and flexible coverage. This paper proposes a reliability enhancement scheme for remote control services in power distribution, and verifies its effectiveness through experiments in practical power distribution scenarios. The scheme utilizes double network based dual-mode and secure encryption devices to achieve dual network availability. With the secure access zone connected to the distribution station and the public wireless network equipment management system deployed, the online ratio of the power distribution terminals would increase by introducing the redundancy in the operation of public wireless communications. Experiments are conducted to remotely control FTUs in practical power lines, and the results demonstrate expected performance.
