摘要
This paper proposes a digital morphological filter to be applied on reference signals for a deadbeat control of a doubly fed induction generator. The signals are wireless-transmitted from a remote operation center and prone to be corrupted by spikes caused by a wireless fading channel. The proposed technique filtering and the control scheme are to be implemented in a microprocessor locally placed at the generator site. The filter acts on the signals at the receiving end of the channel and its outputs serves as clean references to the deadbeat control. In order to evaluate the filter performance, corrupted signals have been generated by means of a simulated channel linking the remote center and the induction generator. The results show the method is efficient in filtering out the spikes without provoking excessive delays.
