OPERATING PRINCIPLE

The single-line diagram shows an On-Grid system connected to a Betta Hydroelectric Generating Station:

• The drive operates in Micro Grid mode, ensuring constant voltage and frequency - supporting Generator variations;

• REG filter is the sinusoidal filter at the output of the converter, whose mission is to eliminate any voltage peaks and feed the output transformer with a pure sine wave;

• The transformer converts the voltage to the desired level of the power grid;

• The voltage and frequency of the circuit are monitored in the frequency converter, synchronizing perfectly with the mains.
