Long gone are the days when only engineers that worked with large electric motors and high power electric loads needed to worry about power factor. The introduction of switching power supplies into electronic systems has led to increasing international legislation, moving power factor up the list as a key concern for most engineers developing systems that run on ac mains power. Power factor pf is the ratio of real power P flowing to the load, to the apparent power in the circuit S. It is a sinusoidal waveform and therefore expressed as dimensionless number between -1 and For a purely resistive load, the two figures are identical; for a reactive load the arithmetic for the apparent power produces the same figure, that is, the product of the RMS values of voltage and current.

Harmonic filter design and power factor correction in a cement factory Abstract: This paper presents, a study of harmonic filters design to minimise harmonic distortion caused by a harmonic source such as drives and power factor correction in a cement factory. Nonlinear loads and rolling mill drives generate significant harmonic currents that flow through the plant and utility power system. These harmonic currents cause system voltage distortion and power loss in the system and interact with power factor correction capacitor banks leading to equipment failures.

Power Factor Correction and Harmonic Filtering Planning in Electrical Distribution Network

This paper presents a multi-objective algorithm for power factor correction and harmonic filtering planning in distribution networks considering capacitor banks, single-tuned passive filters and high-pass passive filters allocation. A strength Pareto evolutionary algorithm II is used. Investments costs, power and energy losses costs and harmonic mitigation are considered in the solution.

Show all documents Chapter L Power factor correction and harmonic filtering For consumers whose tariffs are based on a fixed charge per kVA declared, plus a charge per kWh consumed, it is evident that a reduction in declared kVA would be beneficial. The diagram of Figure L16 shows that as the power factor improves, the kVA value diminishes for a given value of kW P.
