Installing a capacitor bank in the field, only to find out that it causes major problems, can be an expensive exercise.
Simulations can determine problems before the installaton commences.
This course provides an overview of using computer simulations to understand and study power quality phenomena. Harmonic studies are performed to evaluate resonances caused by power factor correction banks, to compute the additive effects of various harmonic loads, and to perform IEEE-519 compliance calculations. This seminar will show how harmonic loads are represented, how power delivery systems are modeled, and how the program is used for IEEE-519 evaluations. Example case histories are presented showing harmonic resonance caused by power factor correction capacitors, the effect of phase angle cancellation using delta-wye transformers, and the design of harmonic filters. Transient studies are performed to study the response of power systems to switching operations, load rejection, power electronic modeling, and control system dynamics.
