Power Quality in Electrical Machines and Power Systems

Ewald Fuchs, Mohammad A. S. Masoum

商品描述

Power Quality of power systems affects all connected electrical and electronic equipment. Power Quality is a measure of deviations in voltage and frequency of the particular supply system. In recent years, there has been a considerable increase in nonlinear loads; in particular distributed loads, such as computers, TV monitors and lighting. These draw harmonic currents which, when distorted, have detrimental effects including interference, loss of reliability, increased operating costs, equipment overheating, motor failures, capacitor failure and inaccurate power metering. This subject is pertinent to engineers involved with electric power systems, electronic equipment, computers and manufacturing equipment. This book shows readers to understand the causes and effects of power quality problems such as non-sinusoidal wave shapes, voltage outages, losses due to poor power quality, origins of single-time events such as voltage dips, voltage reductions, and outages, along with techniques to mitigate these problems.

. Provides theoretical and practical insight into power quality problems of machines and systems
. Problems/solutions at the end of each chapter dealing with practical applications
. Includes application examples including SPICE, Mathematica, and MATLAB examples

商品描述(中文翻譯)

電力系統的電力品質影響所有連接的電氣和電子設備。電力品質是對特定供電系統的電壓和頻率偏差的衡量。近年來,非線性負載有顯著增加,尤其是分散負載,如電腦、電視監視器和照明設備。這些負載會產生諧波電流,當諧波失真時,會產生干擾、可靠性損失、運營成本增加、設備過熱、馬達故障、電容器故障和不準確的電力計量等不良影響。這個主題對於從事電力系統、電子設備、電腦和製造設備的工程師非常相關。本書向讀者展示了如何理解電力品質問題的原因和影響,例如非正弦波形、電壓中斷、因電力品質不良而導致的損失,以及單次事件(如電壓波動、電壓降低和中斷)的起源,並介紹了緩解這些問題的技術。

本書提供了機器和系統電力品質問題的理論和實踐見解。
每章末尾都提供了處理實際應用的問題/解決方案。
包括應用示例,包括SPICE、Mathematica和MATLAB示例。
