Protection Scheme for HVDC Converters to Limit Fault Current against Dc-Side Faults

Authors(3) :-M. Krishnakumari, P. Bharath Kumar, Dr. P. Sujatha

This paper presents a protection scheme for HVDC converters against DC-side faults with current suppression capability by combining and connecting double thyristor switch scheme across ac output terminals of the HVDC converter.The severity of dc-side faults can be limited by connecting double thyristor switches across the semiconductor devices.By turning them on, the ac current contribution into the dc side is eliminated and the dc-link current will freely decay to zero.This protection scheme provides advantages, such as lower dv/dt stresses and lower voltage rating of thyristor switches in addition to providing full seperation between the converter semiconductor devices and ac grid during dc-side faults.A simulation case study has been carried out to demonstrate the effectiveness of the proposed scheme.
