Rural electrification using overhead HVDC transmission lines

Design and selection criteria for HVDC overhead transmission lines insulators

Accurate Electromagnetic Transient Simulations of HVDC Cables and Overhead Transmission Lines

This paper introduces three different procedures for improvements in the accuracy at very low frequencies of time domain simulation models for overhead lines and underground cables. In the first two methods, a suitable modification is introduced to the functional form of the rational function approximated in the curve fitting procedure for the phasedomain model, such that the model is perfectly...

Pole-to-Ground Fault Analysis and Fast Protection Scheme for HVDC Based on Overhead Transmission Lines

Flexible direct current (DC) transmission network technology is an effective method for large capacity clean energy access to power grids, but the DC short-circuit fault detection for it is a difficult problem. In this paper, the pole-to-ground fault transient characteristics in a multi-terminal DC power grid, based on overhead transmission lines and DC circuit breakers, are analyzed firstly. T...

Rural Electrification

Power transmission capacity upgrade of overhead lines

Electric power consumption, has been increasing uninterruptedly, being this increase specially accelerated in the last years. New power generators are been built, the installed power increases each year, thus it is necessary a way to transmit the bulk energy. Nowadays electric lines are saturated, they are reaching critical values of ampacity and sag. Therefore building new lines is necessary t...
