Abstract
This invention relates to a generator arrangement, including: a generator located within a flow passage wherein the flow passage has an inlet and an outlet, and the generator includes at least one contra-rotating blade arrangement which is configured to be rotated about a principle axis of the generator by a flow of liquid in the flow passage, and wherein the at least one blade has an adjustable pitch; an array of sensors located downstream of the blade arrangement for detecting the outlet flow conditions; a controller for determining the outlet flow conditions on the basis of conditions sensed by the sensor array; and, a pitch control system for adjusting the pitch of the at least one blade so as to affect the flow conditions at the outlet of the flow passage.

A generator arrangement, comprising:
- a generator located within a flow passage wherein the flow passage has an inlet and an outlet, and the generator includes at least one contra-rotating blade arrangement which is configured to be rotated about a principle axis of the generator by a flow of liquid in the flow passage, and wherein at least one of the contra-rotating blades has an adjustable pitch;
- an array of sensors located downstream of the blade arrangement for detecting the outlet flow conditions;
- a controller for determining the outlet flow conditions on the basis of conditions sensed by the sensor array;
- and,
- a pitch control system for adjusting the pitch of the at least one blade so as to affect the flow conditions at the outlet of the flow passage.
