Development of Design Methods for Harmonic Voltage Reductionon Electric Power Distribution Systems (REU Supplement)

近年来，电力系统中的谐波问题日益引起人们的关注。电力电子器件的发展和由此产生的电力变流器在系统负载中的使用大大增加了注入系统的谐波电流水平。这项工作的目标是开发确定电容器组位置和大小的方法，以降低系统在显著谐波处的阻抗。所用的方法是零极点分析和输入输出分析，以确定电容器放置对特征值灵敏度或增益灵敏度的影响。

The presence of harmonics in power systems has become a matter of increasing concern in recent years. The development of power electronic devices and the resulting use of power converters in the system load have greatly increased the level of harmonic currents being injected into the system. The goal of this work is to develop methods for determining capacitor bank location and sizing so as to reduce the system impedance at the significant harmonics. The methods used are pole-zero analysis and input-output analysis to determine the effects of capacitor placements on eigenvalue sensitivities or gain sensitivities.
