1 Session Goals Larry Stanley, Sr. Regional Business Development Engineer, Water Segment Matthew LaRue, ABB Drives Product Manager Philadelphia District, Baldor of Philadelphia NJWA - Harmonics and Drives Proper System Design Understand what harmonics are Understand why harmonics may be a concern Provide simple guidelines for when to be concerned Understand what options are available for addressing harmonic issues October 21, 2016 Slide 1 October 21, 2016 Slide 2 Harmonics What? Harmonics What? Non-linear loads draw non-sinusoidal current from a sinusoidal line (current doesn t look like voltage): Non-incandescent lighting Computers Uninterruptible power supplies Telecommunications equipment Copy machines Battery chargers Any load with a solid state AC to DC power converter Electronic variable speed drives October 21, 2016 Slide 3 October 21, 2016 Slide 4 Harmonics Key Concepts The Real World, 6- Pulse Drive Non-linear loads draw current in a periodic non-sinusoidal or distorted manner Line transients are not harmonics Harmonics or harmonic content is a mathematical concept implemented to allow quantification and simplified analysis of nonlinear waveforms Harmonics are typically present in both network currents and network voltages Non-linear current draw creates non-linear voltage as it flows through the electrical network Current harmonics Voltage harmonics PWM Drive Input Current October 21, 2016 Slide 5 October 21, 2016 Slide 6 1

2 The Theory: Fundamental, 5 th and 7 th Harmonics Harmonic Content, 6- Pulse Drive Fundamental 5th PWM Drive Harmonic Input Spectrum Components Fundamental 7th 5th Summation 7th 11th 13th October 21, 2016 Slide 7 October 21, 2016 Slide 8 Harmonics Why worry? Harmonics Why worry? Harmonic Current Distortion Added heating in transformers and cables, reduces available capacity May stimulate a PF correction resonance condition Excessive voltage Overheating of capacitors Tripping of protection equipment Shutdown / damage to electronic equipment May cause telephone or electronic interference October 21, 2016 Slide 9 October 21, 2016 Slide 10 Beware Harmonic Resonance Harmonics Why worry? (cont.) Harmonic Voltage Distortion Undamped power factor correction capacitors on the same bus as nonlinear loads may create a resonance condition with consequent severe bus voltage distortion and excessive peak voltage Increased heating in motors and other electromagnetic equipment Noisy operation of electromagnetic equipment Malfunction of sensitive electronics Nuisance tripping of electronic circuit breakers Equipment downtime Premature component failures Failed transformers, motors and capacitors Compliance with codes or specifications October 21, 2016 Slide 11 October 21, 2016 Slide 12 2
