Title:
FLUID POWER GENERATION DEVICE AN METHOD FOR CONTROLLING FLUID POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/155278
Kind Code:
A1
Abstract:
Disclosed is a fluid power generation device that can cause the energy of a fluid that a rotor receives to match the electrical energy that a generator outputs. The fluid power generation device is provided with a drive device (24) that causes at least one of a rotor (9) and a stator (7) of the generator (8) to move in the axial direction of the rotating axis (4), and as a result, changes the length of overlap of one of either the stator (7) and the rotor (9) with respect to the other. A flow-speed measurement device (6) measures the flow speed of the fluid, and a control device (10) controls the length of overlap of the generator (8) on the basis of the measured fluid flow speed and the relationship between a predetermined fluid flow speed and an indicator (contact ratio) relating to the length of overlap of the generator (8).
