Developing large Offshore Wind Farms (OWFs) represent an efficient and reliable power generation. To improve the efficiency of such OWFs, Voltage Source Converter based High Voltage DC transmission (VSC based HVDC) system is used. However, the VSC-based HVDC transmission systems are subjected to DC faults frequently, and dc circuit breakers of higher rating are required to provide protection against such faults. Hence the Offshore Wind farms integrated by VSC-HVDC are expected to have fault ride-through (FRT) capability during such DC fault conditions. This research work proposes a VSC based HVDC system provided with a Fault Tolerant Breaker (FTB), in between the DC line in order to limit the DC fault current. This provides an efficient and reliable power transfer in the system without disturbing the power supply during any such DC fault conditions. The simulations are performed through MATLAB/Simulink software and results were obtained.
