ABB Ultra Low Harmonic Variable Speed Drives

Understanding Harmonics

To appreciate the full benefits of ABB’s Ultra Low Harmonic drives, it’s necessary first to understand the concept of harmonics. Essentially, harmonics are unwanted currents that flow within a power system, caused by non-linear electrical loads. Non-linear loads, such as variable speed drives, switch power on and off abruptly to control the output. This action can cause a distortion of the electrical waveform, resulting in harmonics.

Harmonics have the potential to impact negatively on power systems. They can cause heat build-up in equipment, leading to premature wear, additional energy loss and potential failure of electrical infrastructure.

In a perfect world, we would want a power system to contain only the fundamental frequency (for instance, 50 Hz in the UK). However, due to the nature of our modern electricity networks, which includes a mix of linear and non-linear loads, a series of harmonic frequencies often emerge.

Introducing ABB Ultra Low Harmonic Variable Speed Drives

ABB’s cutting-edge Ultra Low Harmonic Drives are specially designed to curb harmonic distortion. Engineered to the highest standards, they perform as standard drives, whilst ensuring harmonic levels meet the strictest requirements set by power utility companies.

These drives use an advanced control algorithm that monitors and dynamically adjusts the drive’s operation. They are designed to eliminate the need for additional filtering equipment, thus minimising footprint and reducing the complexity of installation and maintenance.
