Interaction of Harmonics with Capacitors
Abstract
Investigates interaction of harmonics with capacitors. First the main applications of capacitors in power systems are outlined: power factor correction, definitions of displacement power factor and total power factor which includes harmonics. Thereafter, the power quality issues associated with capacitors are discussed, including series and parallel harmonic resonances, and transients due to capacitor switching. Frequency and capacitance scanning techniques including harmonic voltage, current and reactive-power constraints for capacitors are addressed next. Feasible exemplary operating regions for safe operation of capacitors in the presence of voltage, current and reactive-power ...
