The Effect of Speed on the Power Factor of a Grid-Connected Three-Phase Induction Generator

The development of electrical energy sources continues to grow along with the development of electrical energy, in line with the increasing electricity demand. One of the power plants developed uses a three-phase induction electric machine. Several studies have been conducted on this electric machine because of its many advantages, such as simple construction, easy control, low maintenance, and affordable machine prices. Three-phase induction machine analysis has been carried out. It is necessary to study the effect of rotor rotational speed on the power factor of laboratory-scale induction machines. The trick is to operate a three-phase induction machine with a network-connected operating mode. This research method requires an excitation current in the form of reactive power from the network. The prime mover drives the mechanically connected induction machine by increasing the rotational speed of its rotor. This technique is used to prove the change in the power factor of a three-phase induction machine and its effect when the rotational speed is changed. The results of the study are used to prove the analysis of the research that has been done so that the value of the power factor will be better when the rotational speed of the three-phase induction generator is increased.
