6 FAQs about [Total current distortion of photovoltaic inverter]

Does a PV inverter have a high current total harmonic distortion?

It is found that the PV inverter presents high current total harmonic distortion levels at power levels below its rated value. This paper proposes mathematical models in order to characterize the current total harmonic distortion and the power factor at two different operation modes.

What is the Distortion limit of a PV inverter?

According to the standards, the distortion limit of the odd harmonics orders three, five, seven, nine and eleven must be less than 4% when the inverter is operating at nominal power. The currents and voltages harmonics components analyzed and compared at 10% and 70% of relative power for two different operation modes of the PV inverter.

Does low power level of PV inverter affect voltage distortion?

During low power level of PV inverter (due to low solar irradiance), odd order current harmonics (3rd (5%), 5th (3%) and 7th (2.8%) order) increases. However in all PV power level, voltage distortion in 5th harmonic order was more intense with value of only around 0.7–0.9% and no changes was found in overall voltage THD level.

What is distortion factor in PV inverter?

The distortion in the voltage or current waveform at the output of PV inverter or when supplying a nonlinear load is known as the distortion factor (DF), given by (6). When supply voltage and current are not in-phase with each other, they are represented by displacement power factor (DPF), expressed as (7).

Do inverters present harmonic distortion at different levels of relative power?

It is noted that at relative power less than 10% or 20%, the inverters may present current with levels of harmonic distortion higher than recommended values by the technical and specification standards. Table 5. Total harmonic distortion in current at different levels of relative power. 4.3. Harmonics assessment and relative power

What is the Distortion limit of a harmonic inverter?

Harmonics currents and harmonics voltages analysis According to the standards, the distortion limit of the odd harmonics orders three, five, seven, nine and eleven must be less than 4% when the inverter is operating at nominal power.
