Distribution System Harmonic Filtering

Sponsor: Idaho Power

Client: Dave Angell - Idaho Power

Technical Contact: Kelly Hulse - Idaho Power


Just West of Pocatello lies a large agricultural base.  Irrigation is the key to a good crop yield.

The AC motors used to pump water for irrigation use Variable Frequency Drives. 

These VFD's are causing harmonic current problems outside the IEEE 519 standard

Our project consists of developing a process to mitigate harmonics for any given feeder, using the Pleasant Valley as the proof of concept
