Abstract: With global warming and sea levels reaching an unprecedented level, mankind has begun to realise the disastrous effects of burning fossil fuels on Earth. To reduce the impact of climate changes, a huge reduction of greenhouse gases emission is necessary. In the search for alternative energies, wind power is gaining success as a clean and abundant alternative energy, so much that it has evolved into large scale wind farms for energy harnessing. In this project, a new configuration of the doubly fed induction machine (DFIG) is being experimented. It uses a Nine Switch converter (NSC) and attempt to control the DFIG. The DFIG will be synchronised to the grid via the stator terminals, instead of the rotor terminals. Since the converters are situated at the rotor side, there is a significant reduction in the ratings and required number of converters for operation, hence leading to cost savings. Moreover, synchronisation performed at the stator terminals allows the ease of connection and disconnection of the DFIG in scenarios of grid faults or unbalanced grid conditions, hence transforming wind turbine into an uninterruptible power supply (UPS) and improving its efficiency.
