Abstract: A wind turbine generator 1 is connected to a section 2 of an electricity grid 3 via a converter 4, which converts the ac output power from the generator into three-phase electric power at the voltage and frequency of the grid 3. The converter 4 comprises silicon carbide transistors which act as ON-OFF switches which are controlled so as to create a voltage profile which is the same as that of the grid voltage. Each grid section 2, 2' has a respective circuit breaker 10, 10' which disconnects the associated section from the remainder of the grid 3 in the event of an abnormally high current. The converter 2 includes a fault detector 11 arranged to detect grid faults, such as an abnormally low voltage level which, in response, generates an alarm signal which causes a high-level transient current to be supplied to the grid 3 sufficient to trip the circuit breaker 10' so as to disconnect the faulty section of the grid. By using silicon carbide transistors, which can withstand high operating temperatures, a higher-level current can be generated than would be the case with converters using conventional silicon transistors.
