Effect of HVAC System on Neighbouring Pipelines and
Communication Cables

A. Abu-Siada, M. Bahram
Curtin University of Technology, Australia

Abstract
Sharing of common corridors between power lines, pipelines and telecommunication lines is becoming a familiar scene. High levels of voltages can be induced in services which run in parallel or in close vicinity of high voltage AC transmission lines, in particular during a fault on the transmission line. These hazardous voltages can affect people coming into contact ....etc

Life Asset Management of the ElectricalComponents in Medium-Voltage Networks
A general consideration of some representative electrical components is necessary for the assessment of the lifetime of the electrical apparatus. This is necessitated by the fact that the large amount of electrical apparatus and the costs of an individual diagnosis in medium-voltage network are high. The investigation must be focussed on the general ageing mechanisms of the individual electrical components.This article presents a new method f ....etc

More Info About medium voltage VFD

Variable-frequency drive
From Wikipedia, the free encyclopedia

Small variable frequency drive

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, mi ....etc

LOADABILITY ASPECTS FOR MEDIUM VOLTAGE
DISTRIBUTION NETWORKS WITH INTEGRATION OF
DECENTRALIZED GENERATION
ABSTRACT
Decentralized Generation (DG) is an emerging concept in the electricity sector; its
integration into distribution networks may have a significant impact on different
technical aspects. The main aim of this paper is the investigation of the impact of
DG on the loadability of medium voltage distribution networks. The loadability is
evaluated in two aspects, the maximum loading according to the voltage limit (VL)
and the m ....etc

ABSTRACT
Urban electrical power systems with steep demand increase need easily located solutions with short lead time from decision to transmission. While AC cable solutions can offer sufficient power ratings, the problems of load controllability and short circuit power increase with every added circuit. These problems may be countered with Voltage Source Converter (VSC) based technology using Cables for transmission, such as HVDC Light. This technology offers up to 500 MW per station with small footprint, ideal for in feed to city centers. ....etc

INTEGRATION OF DISTRIBUTED GENERATION IN
MEDIUM VOLTAGE GRIDS - PROTECTION ISSUES
Keywords: Distributed Generation; Medium Voltage-grid; Protection;
ABSTRACT
At this moment climate change and CO2 reduction are hot topics in relation to en-
ergy production. Efforts are made to stimulate development of sustainable energy
sources, such as wind turbines and PV-systems. Also the combined heat and power
production is encouraged. This has lead to an increasing penetration of small gen-
erating units in medium voltage (MV) grids. Small genera ....etc

underground cables seminar report

Abstract

Underground cables are the electric power transmission cables. Because of their reliability on transmitting, they used in congested urban areas and in thick population areas, where overhead transmission is dangerous. Underground cables have low maintenance cost, less chances of faults, smaller voltage drop. In recent improvements in the design and manufacture have led to development of cables suitable for use at high voltages. Electric power can be transmitted or distributed either by overhead system ....etc
