Investigation of Power Factor on Harmonic Effect due to Types of Voltage Source

Abstract

This paper discussed about power factor on harmonic effect due to types of voltage source. Usually, the voltage source is sinusoidal. But in actual condition the load that has voltage sources through the elements where the output voltage of element as input to load is not pure sinusoidal, for example at Power of Common Coupling (PCC) between transformer and linear load and nonlinear load. The research has been done with Schhafner Power Quality Analyzer and was focused to power factor (p.f.), Total Harmonic Distortion (THD), and harmonic energy losses cost from measurement where load is Induction motor and Adjustable Speed Drive (ASD). As voltage source in this research are sine wave, square wave and combinations of 3 rd , 5 th and 7 th harmonic order like harmonic 313, and harmonic 357.

Multi-Area Economic Dispatch Performance Using Swarm Intelligence Technique Considering Voltage Stability

“…where Z ij is the magnitude of the impedance of transmission line connecting bus i and bus j, Q j is the reactive power at the receiving end bus, V i is the sending end bus voltage [22], [23] and X ij is the magnitude of the reactance of the transmission line connecting bus i and bus j. According to [21], FVSI values approaching the value of 1.00 indicates the instability of the line.…”
