摘要

The widespread adoption of variable frequency drive technology is allowing electricity to be utilized more efficiently throughout most of the world. Following right behind the adoption of drives is the establishment of harmonic distortion limits. This can cause confusion and may instill needless fear in people involved in the decision to apply variable frequency drives. While the drive utilizes electricity most efficiently, drives are also known to cause harmonic distortion on the power system. This paper suggests economical solutions for meeting harmonic distortion limits while improving the reliability of the facility power system. Various solutions are presented along with their typical performance characteristics. Included are guidelines for applying the various solutions, expected residual harmonic levels for the various solutions, as well as a simplified approach to system harmonic analysis.
