Fault ride-through of renewable energy conversion systems during voltage recovery
Journal of Modern Power Systems and Clean Energy, 2016 Asymmetrical voltage swells during recovery of a short-circuit fault lead to fluctuations in the dc-link voltage of a renewable energy conversion system (RECS), and may induce reversed power flow and even trip the RECS. This paper studies characteristics

A modular DC transformer with DC fault ride-through capability
Journal of Physics: Conference SeriesAbstract DC transformers are core equipment for constructing multi-voltage-level DC distribution networks. However, mainstream DC transformer topologies, which are based on the Input-Series Output-Parallel Dual Active Bridge (ISOP-DAB), currently have deficiencies in fault blocking capability and fault-tolerant redundancy design.

FAULT RIDE-THROUGH CAPABILITY AND DAMPING IMPROVEMENT IN DFIG
, 2016 Doubly-fed induction generator wind turbine is susceptible to faults and requires crowbar protection. When the crowbar is triggered, the rotor is short circuited over the crowbar impedance. Then, the doubly-fed induction generator operates as a squirrel-cage induction generator that tends to absorb large amount of reactive power from the grid during ...
