dfig rotor circuit superconducting protection system

摘要

dfig rotor circuit protection superconducting system The proposed embodiment is a superconducting system characterized in that a superconducting protector is inserted into the rotor circuit. The system is further characterized by using a three-phase limiter connected between the rotor and converter b2b (5) or by inserting the shield on the ground side between the rsc converter and the dc link of converter b2b (6).
