Electrical System Modelled is Modelled in ETAP Software along with harmonic current & voltage sources - Codes & Standards
Harmonic Studies to be performed as per IEEE-519, Recommended Practices and requirements for harmonic control in Electrical Power System - Methodology
Harmonic Currents & Voltages in system are either measured at site using Power Analyzer (Fluke 435 Series) complying to IEC 61000. Optionally the Harmonic Spectrum can be obtained from each equipment supplier - Analysis & Results
Harmonic Load Flow is performed for harmonic frequencies ranging from 2nd Harmonic to 49th Harmonic. Harmonic Frequency Scan Analysis is performed to plot Impedance v/s Frequency and System Resonant Frequency is obtained. Harmonic Filters are designed based on Z v/s F
