After successful completion of the course, students are able to to understand and interpret system equations of this type of machines. In addition, the pros and cons of doubly fed induction machines are understood as well as connections and possibilities to influence and control state variables like active and reactive power, speed and torque.
Advantages and disadvantages of doubly fed induction machines; system equations; basic operation; definition of specific tasks (wind energy generator, pump, ...); control methods (active, reactive power; speed, torque); design of drive components; practical implementation of the control loop; measurement on a wind energy generator.
Theory and practical verification on a test stand including interpretation of measurement results.
Each step of the exercise and measurement has to be checked and verified. A documentation of all necessary key points has to be done.
The student must have at least 1 of the course(s) completed listed below:
