| Abstract |
In general, power electronics equipments in which switching action of the semiconductor switches provided with shows typically one of nonlinear load characteristics, cause harmonic currents to flow into the power distribution system connected. These generated harmonics can exert influence on the other connected apparatus as well as can be amplified under some circumstance. In this paper, we give an investigation on the parallel resonance between power system impedance and a capacitor when the power factor correction capacitor banks are switched into the electric power distribution system in a building. It is known that a lot of harmonics may be generated from UPS(Uninterruptible power supply) provided for critical loads. We also study the influence of current harmonics on the actual electric power distribution system. |
