Techniques for Energy Conservation in AC Motor-Driven Systems

摘要

This report evaluates and compares techniques for energy conservation by reducing losses in ac motor driven systems proposed by the technical community in response to surging cost of energy. Report objectives are to provide better understanding of underlying principles and to evaluate technical and economic viability of these techniques for various applications. An important aspect considered is the impact on electric utility system in terms of harmonics, power factor of operation and Electro-Magnetic Interference (EMI). The techniques evaluated in this report are listed below.
