Abstract

This paper proposes a fault tolerant LC resonant DC/DC converter for offshore wind farm applications. A multi-terminal wind energy conversion system of three wind turbine units connected in parallel configuration for HVDC application is investigated. The design and modelling of the proposed system are addressed. The main aim of the LC circuit is to maintain the steady state fault current at rated value. This results in protecting the converter semiconductors. In such case, the permanent fault current can be interrupted by the AC mechanical circuit breaker. Moreover, it not required any more to protect the antiparallel diode by connecting thyristor in parallel. The aforementioned design solutions are confirmed and verified by detailed simulations using MATLAB/SIMULINK software. The simulation includes grid integration and interaction between the wind turbine units.
