Reactive Power Compensation using a Voltage Source Generator full text in English

摘要

Power quality has a significant effect on economic indicators and transport network and is a defining parameter for evaluating its performance. To a large extent, the noise who leading to lower level of power quality are determined by consumer activity (harmonics, unbalance, flicker). But production systems, transport and distribution, due to specific requests that arise (lightning, wind, ice deposits, damage) can be the source of disturbance in the form of interruptions, dips, surges, voltage and frequency variations. Also, to overcome the limits of power, the transmission may be the source voltage harmonics, both corona discharge and by operating the nonlinear characteristic of magnetic circuits. Development of electricity transmission network should be taken to ensure the standard of power quality in network interface distribution points. Traditional means for improving the quality of electricity transmission network and to large industrial consumers, have focused on only increase the power factor up to the neutral (0.92) and taking technical - organizational measures for limiting consumption of reactive power. This paper will present a description of the principle of dynamic compensation of reactive power static generator, highlighting the advantages of its use.Keywords: 3 level inverter, SVG, SVC, power factor, reactive power
