1.The Thyristor is a natural commutation device. What does that mean?
2.Mention two reasons why the HVDC might be your choice as a power system designer to transfer large amount of power.
3.What are the main limitations of the Thyristor based HVDC transmission system?
4.What determines the maximum firing angle " alpha" at the inverter side?
5.What determines the minimum firing angle at the rectifier side?
6.What is the commutation failure? And why it may happen?
