Control and measurement device for under water tidal flow power generation

This paper introduces a measurement and control device for an under water tidal flow power generator. There are a number of designs for under water tidal flow turbine. One concept being considered is to have a vertical axis turbine with funnels of both sides to direct and concentrate the flow of water onto the turbine. To test this concept we are building a test device that varies the angle on one funnel and measures the power to find the angle that maximises the power. The aim is to develop the control system of the test device to measure the power and conditions of the turbine at different funnel opening angles.
