Abstract: A method of measuring electrical characteristics of a transducer in a wind turbine generator control system is described. The method comprises measuring one or more electrical characteristics of a transducer of the control system, and comparing the measured electrical characteristics to one or more reference electrical characteristics, the reference electrical characteristics being one of (a) previously measured electrical characteristics of that transducer, (b) reference electrical characteristics stored in a database, and (c) previously measured electrical characteristics of an identical or similar transducer in another wind turbine generator.

Abstract: A method of detecting electrical failures in a wind turbine generator control system is described. The method comprises sending a test pulse through a signal path within the control system and detecting the test pulse once it has passed through the signal path, measuring a current through the signal path, and determining an input status and/or an output status of the signal path. Then, the nature of the electrical failure is identified based on a combination of the detected test pulse, the measured current and the determined input status and/or output status of the signal path.

Abstract: A method of measuring transducer currents in a wind turbine generator control system is described. The method comprises selectively activating a set of one or more transducers in a group of transducers, taking a first measurement of the current through the group of transducers, selectively activating a different set of one or more transducers in the group of transducers, and taking a second measurement of the current through the group of transducers.

Abstract: A wind turbine generator controller is described. The controller comprises switching circuitry, for selectively activating and deactivating one or more transducer circuits, and overcurrent detection circuitry, for detecting an overcurrent state in relation to one or more of the transducer circuits. The switching circuitry is responsive to the detection on an overcurrent state to selectively deactivate one or more of the transducer circuits.
