Industrial customers use three-phase power consumption with different power factors. If their power factor drops below a prescribed value, power losses in transmission lines increase. For this reason, the customers have to pay a penalty. In order to avoid these troubles, industrial customer installs power factor correction capacitors.
The Advanced Power Factor Compensation Application, "AEL-EECFP", has been developed as a complement to AEL-RPC in order to study in depth the power factor compensation when there is a dynamic load.
The three-phase induction motor is the most used motor in the industry. For this reason, a group servomotor and induction motor is included in this application. With this group, the user can cause different motor load conditions modifying the power factor.
Power factor compensation (when the induction motor is working) is necessary to avoid excess reactive energy. For this purpose the user can realize it manually through the three-phase capacitors module or automatically with advanced power factor controller module together three-phase digital capacitor banks module. The first module measures the voltage and current values of the grid and calculates the power factor. Such module enables the connection of six stages of capacitors, which enable the regulation of the power factor according to the desired value.
