Abstract
In order to take effective countermeasures for harmonics suppression and harmonic disturbances in distribution systems, precise simulation on harmonic power flow is required. Precise equivalent circuit on harmonics is required for the simulation. However, it is impossible to obtain such equivalent circuit by dividing harmonic voltage by harmonic current simply. Therefore, we have investigated the load characleristics, which can be separated as load admittance and harmonic current source, by opening and closing static capacitors in distribution systems.
As a resull, we have made a proposal for forecast model of harmonic impedance on load side varying with load characteristics.
