Harmonic Analysis and Solution

Harmonic analysis & solutions
benefits
(a) identify power quality problems
(b) reduce nuisance trips
(c) extend equipment life
(d) improve system reliability
scope
1. Harmonic analysis is typically conducted as part of a power quality study to identify
the source of harmonics and develop a plan for corrective action.
2. A harmonic analysis study can:
(a) identify harmonic problems
(b) reduce nuisance trips
(c) calculate load flow
(d) identify & analyze telephone interference
problems
(e) identify parallel resonance condition
3. Once a study is complete, a report will be issued including:
(a) rms voltage & current, total harmonic distortions, bus impedances (magnitude
& angle) tabulation, graphical one-line display of harmonic results, voltage &
current harmonic spectrum plots, fundamental load flow results
(b) recommendations for corrective action.
