Research on Early Warning Technology of Power Transmission Lines

A Mobile Manipulator for Installation and Removal of Aircraft Warning Spheres on Aerial Power Transmission Lines

A semi-autonomous robot for autonomous installation and removal of aircraft warning spheres on overhead wires of electric power transmission lines is described here. Hybrid systems methodology was used to model the basic modes of operation of the robot, which includes both autonomous and tele-operation possibilities. Several sensors and actuators including a custom made gripper are used to acco...

Transmission expansion planning based on merchandizing surplus of transmission lines

This paper proposes an optimal transmission expansion planning (TEP) which is based on determining share of each line in merchandizing surplus (MS) of system, determining by Independent System Operator (ISO). The more share of a line in MS of system denotes the priority of a line for expansion. The procedure of determining MS of each line in a power system is based on determining the MS share o...

PDF Based Icing Image Recognition Applied to Online Early Warning System for Transmission Lines

This paper proposes an online early warning technique and the probability distribution function (PDF) based icing image recognition for overhead power transmission lines. The main functionality of the online early warning system for overhead transmission lines firstly suggested in this paper is the early warning of icing, forest fire, lighting, insulator flashover, conductor galloping and invas...

Power Quality Early Warning Based on Anomaly Detection

Different power quality (PQ) disturbance sources can have major impacts on the power supply grid. This study proposes, for the first time, an early warning approach to identifying PQ problems and providing early warning prompts based on the monitored data of PQ disturbance sources. To establish a steady-state power quality early warning index system, the characteristics of PQ disturbance source...
