Power Upgrading of Transmission Line
by Combining AC DC Transmission



H. Rahman and B. H. Khan, Senior Member, IEE


abstract

Abstract
Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits in order to keep sufficient margin against transient instability. With the scheme proposed in this paper, it is possible to load these lines very close to their thermal limits. The conductors are allowed to carry usual ac along with dc superimposed on it. The added dc power flow doe ....etc

Preliminary results, based on experimental research in the laboratory and numerical study on the detection of fault lines live in high-voltage composite insulator is depicted conducting the proposed method is based on the E-field of non-invasive sensing Using pigtail electro-optic (EO) and compact single-ended probe. Measurement and numerical simulation of FEM CALCULATIONS were made on the stalled clean 28 kV polymer insulators on defects of different size and conductivity were modeled. Based on modeling the optimal location and orientation of ....etc

Increasing grid connectivity is accompanied
with various factors viz. wide variation in
generation as well as loads on daily/seasonal basis,
spread of the grid geographically, multi direction
flow of power, open access, unscheduled
interchange (UI) and the need for economic
dispatch. Thus it is necessitates reliable and secure
grid with continuous quality power supply .
Extra and ultra high voltage transmission lines
have been developed worldwide and are
successfully being operated in developed nations.
Recent trends in Indian tra ....etc

Abstract
A new teleoperated system for live line maintenance is developed for electrical util-
ity. It's aim is to increase the safety and comfort of the workers and the overall
e ciency, as well as to reduce labour requirements.Its design is basically like other
similar systems already developed. It consists of a pair of hydraulic driven master-
slave teleoperated manipulators placed on top of an insulated boom, which execute
directly on the hot line tasks commanded via master arms by an operator on the
ground. Tele-p ....etc
