The voltage distortion on industrial systems is becoming an increasingly important issue as large nonlinear loads are introduced. Typical harmonic loads are converter supplied variable speed dc motors and PWM converter supplied adjustable speed ac drives. As the size of the variable speed drives are large the overall power factor of the plant goes down. In this paper a practical case study is presented for a 12 MW industrial plant with two 500 hp dc variable speed motor drives and two 1250 hp ac motors that are supplied through static power supplies. The design of a filter to improve the harmonic contents and also to correct the power factor to 97% is discussed in this paper. The acceptance criteria for the filter performance based on IEEE 519 requirements and the analysis approach using a harmonic analysis program are presented. The use of frequency domain analysis to verify the resonance peaks at various operating conditions are demonstrated.
