Abstract

The design and application of second order high pass filters is described for 2-8000 hp ID fan drives, which reduces the voltage harmonic distortion at PCC (Point of Common Coupling) from a high value of 42.41% to 1.32 % and also brings the current distortion at PCC within IEEE 519 limits. Failure of electronic components of 8000-hp ID fan drives and shutdown of electronic loads downstream of main 13.8 kV buses were observed which led to investigation of harmonic problems and their mitigation. The second order high-pass filters are applied for the first time in the industry for such a harmonic distortion problem.
