Harmonic Analysis

Harmonic analysis is done to carry out measurement of harmonics content and its analysis in the electrical power & distribution system for determining harmonic distortion levels in various substations and to provide recommendations to ensure the harmonic levels shall remain within acceptable limit as per the IEEE standard 519-2014.

The brief scope of harmonic analysis includes the following.

  • Modeling of VFDs, UPS, battery chargers and other non-linear loads up to 415 V PCC level based on the equipment vendor data (load harmonic spectrum) or field measurements.
  • Harmonic analysis to predict distortion levels for addition of a new harmonic producing load or/and capacitor bank
  • Analysis to evaluate alternatives for correcting problems found by measurements.
  • Recommendations on selection and location of filters if the calculated THD levels exceed the permissible limits as specified in IEEE standard-519-2014

Methodology:

Data collection : Measurement of all Electrical parameters like Voltage, Current, kW, Power Factor, neutral current, THD Voltage, THD Current Harmonic and Individual harmonics levels (up to 50th ) at the incomer end of panels.

Analysis: Analysis of the harmonic readings as per IEEE 519-2014 standard with standard software. Provide the recommendation to improve power quality, power factor improvement, and reduction in harmonics levels (if any) to comply with IEEE 519-2014 standards.

Report Submission & Presentation: After completion of study the Consultant will provide the detail study report with workable solution to minimize the impact of harmonic distortion subject to the maximum limits per IEEE 519-2014.
