Effect of Poor Power Factor The major effect of poor power factor is higher value of line current. We know that power factor (pf) is an important parameter for calculation of power in an AC circuit. For a given power and voltage, the current flowing through the line is inversely proportional to the power factor. This means that a poor power factor i.e. low power factor will result in hig...
With the development of society and the increase of demand for electricity, Reactive power compensation technology has developed rapidly, including Static VAR Compensation and Dynamic Reactive Power compensation, and has gained rich operating experience. However, some problems have also been exposed in practice. Some reactive power compensation devices are inconvenient to move, and the equipment m...
The existing power grid is usually equipped with a large number of nonlinear electronic components. These nonlinear electronic components will generate corresponding harmonics during the working process, among which high-order harmonics will interfere with the electrical equipment in the power grid and seriously affect the power supply. Power quality in the grid. In order to reduce the adverse eff...
Due to the rapid development of power electronic technology, the nonlinear characteristics of industrial and agricultural power loads, especially transportation and civil electrical products are becoming more and more serious, and the power factor of users is also declining. Therefore, reactive power compensation devices are more and more widely used. The power compensation device is used to suppl...
Static var generator SVG is adjusted to exchange capacitive or inductive current to maintain or control specific parameters (Power Factor) of the electrical power system. Static var generator is a real time var compensator. SVG provides dynamic reactive power compensation and is directly connected parallely to the bus of networks. SVG's reactive power is generated by capacitors of harmonic f...
Power Factor in Networks Power factor is a measure of the phase difference between the voltage and current in an AC power system. In purely resistive loads (such as an incandescent lightbulb or electric kettle) the current is in phase with the voltage and there is ‘unity’ power factor. Capacitive and inductive loads (such as a capacitor banks or inductive motor respectively) will cause...
Power Factor Correction and Reactive Power Compensation Power Factor Correction(PFC) is done by electricity consumers to avoid penalties on account of large KVA demand or lower power factor. Normally, such penalties are imposed on industrial consumers. Therefore, industries need more lagging KVAr due to induction motors or otherwise, install capacitors banks or Static Var Generator(SVG) for power ...
Capacitive reactive power The reactive current of the load is generally inductive, so we can use capacitor bank to compensate it. However, the reactive power generated by loads such as UPS and charging pile is capacitive. Capacitor banks cannot compensate capacitive reactive power, so the latest reactive power compensation technology SVG Static var generator needs to be used to compensate cap...
