Frequency-Domain Harmonic Analysis Methods

Abstract: There are a large number of frequency-domain analysis methods that are in widespread use. The most popular of these are frequency scans, harmonic penetration, and harmonic power flow. Each of these techniques can be employed on a “per-phase ” (positive or zero sequence) or “multi-phase ” basis and each technique utilizes an admittance matrix system model developed from individual component-level models connected according to system topology. The development of this admittance matrix system model and the frequency-domain harmonic analysis algorithms that make use of it are the subjects of this chapter. The methodology employed in the development of admittance matrix models is based on multi-port networ
