Harmonic Compensation in Power System using Active Power Filters
The advent of power electronics and computerized equipment in recent decades has brought enhanced efficiency and improved system but at the same time also created harmonics and waveform distortion to the power system network. With high harmonic contents present in the supply network, a higher equipment component failure rate or undesirable tripping of sensitive device might be experienced. This...
متن کاملPower System Harmonic Compensation Using Shunt Active Power Filter
This paper shows the method of improving the power quality using shunt active power filter. The proposedtopic comprises of PI controller, filter hysteresis current control loop, dc link capacitor. The switching signal generation for filter is fromhysteresis current controller techniques. With the all these element shunt active power filter reduce the total harmonic distortion. Thispaper represe...
متن کاملModeling of Harmonic Sources Power Electronic Converters
Harmonic problems are not new to electric utility and industrial power systems. In the past, most harmonicrelated problems were caused by large nonlinear loads such as arc furnaces. These types of problems have been effectively mitigated. However, due to the widespread proliferation of power electronic controlled devices nowadays, the problems caused by harmonics are of increasing importance. P...
متن کاملA graph search algorithm: Optimal placement of passive harmonic filters in a power system
The harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. This paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. The objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...
متن کاملOptimal inequalities for the power, harmonic and logarithmic means
For all $a,b>0$, the following two optimal inequalities are presented: $H^{alpha}(a,b)L^{1-alpha}(a,b)geq M_{frac{1-4alpha}{3}}(a,b)$ for $alphain[frac{1}{4},1)$, and $ H^{alpha}(a,b)L^{1-alpha}(a,b)leq M_{frac{1-4alpha}{3}}(a,b)$ for $alphain(0,frac{3sqrt{5}-5}{40}]$. Here, $H(a,b)$, $L(a,b)$, and $M_p(a,b)$ denote the harmonic, logarithmic, and power means of order $p$ of two positive numbers...
