Estimating Future Harmonic Distortion Levels In Distribution Systems Due To Single-Phase Adjustable-Speed-Drive Air Conditioners: A Case Study

Abstract

The increasing application of power electronics in residential, commercial, and industrial loads is gradually increasing current and voltage distortion levels in distribution systems. This trend will accelerate il large loads such as air conditioners are. in the future, powered by electronic drive systems. The objective of this paper is to present the results of a simulation case study in which feeder distortion levels are predicted as adjustable-speeddrive (ASD) air Conditioners become an appreciable fraction of the total load.
