This book was released on 2018-03-21 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2015 in the subject Engineering - Power Engineering, grade: Merit, University of Manchester, course: Electrical Power Systems Engineering, language: English, abstract: This dissertation introduces wind-induced vibrations that influence the performance of overhead line structures. The main focus in this study is on Aeolian vibrations and the quantities related to the calculations of its performance such as safe design tension and fatigue limits. However, there are three main methods that are proposed to evaluate conductors with respect to vibrations which are Safe Design Tension Method, Fatigue Endurance Limits Method, and Energy Balance Method. The safe design tension method is applied on Aluminium Composite Steel Reinforced (ACSR) and All Aluminium Alloy Composite (AAAC). Eventually, a relationship is established between tension of conductor and span length. The fatigue endurance limits method uses bending strain and stress to evaluate the fatigue level on the conductor. The effect of vibration dampers to overcome vibration problems on overhead line conductors is also considered. Moreover, an assessment tool based on Microsoft EXCEL is developed which allows the evaluation of overhead line system conductors based on environmental conditions, mechanical properties, and system specifications. The assessment tool evaluates the overhead line system with respect to bending amplitude or alternatively using the antinode amplitude. The analysis of finding the antinode amplitude is performed using trial and error method by solving the energy balance principal. There are a number of case studies which are analysed using the proposed assessment tool to validate the results and establish a comparison between different types of conductors including 3M Aluminium Conductor Composite Reinforced (ACCR). The comparison includes the role of dampers on mitigating vibration issues using the IEC 6189 Stockbridge damper as a reference in the evaluation p

Download or read book Modelling of Single Conductor and Damper Vibration written by and published by . This book was released on 1995 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a mathematical model of aeolian conductor vibration and a detailed description of the forced response method for the testing of Stockbridge-type dampers. The mathematical model is based on the fundamentals of conductor vibration and is more comprehensive than the popular energy balance method. For example, it is able to account for the effects of travelling waves and nonlinear damping of the conductor and dampers. The paper includes experimental data to emphasize the importance of phase shifting and nonlinearities in the forced response method. An inclusive guide on this method is included in order to assist both new and experienced investigators of Stockbridge-type dampers.
