Total harmonic distortion reduction based energy harvesting
Distributed generation (DG) and solar photovoltaic (PV) systems are just two of the many places multilevel inverters have found a home. The total harmonic distortion (THD) of an
The THD mirrors the inverter's capability to regulate harmonic distortion and the maximum amount of harmonic distortion it could potentially output. However, beyond the hardware and software/algorithm configurations of the inverter, various external factors can negatively impact the inverter's performance and bring about harmonic distortion.
Choosing a solar inverter with low total harmonic distortion (THD) lays the groundwork for maintaining the overall harmonic distortion at an ideal level. It is wise to be aware that investing in a quality inverter means lower risks of potential damage to connected loads.
The standard dictates that a synchronous inverter should avoid harmonics exceeding 5% while generating electricity from a solar photovoltaic generator, thus establishing this as the maximum value. As solar irradiance increases and reaches noon, THDI tends to zero.
This is important for devices that rely on precise power, such as motors and LED lights, which might operate erratically or fail when powered by an inverter with a high THD. A higher THD leads to increased energy losses as the electrical system needs to compensate for the harmonics.
