Swelect Energy Systems Graphic Designer Interview Questions and Answers

A line diagram of a wind turbine generator (WTG) shows the flow of energy from wind to electricity.

• The diagram typically includes the rotor blades, gearbox, generator, and power electronics

• The blades capture wind energy and turn the rotor, which drives the gearbox

• The gearbox increases the rotational speed and sends it to the generator

• The generator converts the rotational energy into electrical energy

• The power electroni...read more

DFIG converters are used in wind turbines to convert variable frequency AC power to DC power and back to AC power.

• DFIG stands for Doubly Fed Induction Generator

• The converter consists of two back-to-back voltage source converters

• One converter controls the rotor current and the other controls the grid current

• The rotor current is controlled to maintain a constant torque on the turbine

• The grid current is controlled to main...read more
