Abstract

A power generator (1, 110) according to an embodiment includes a propeller (13), a position detector (16), and a pitch controller (50). The propeller (13) includes a plurality of blades (13b1, 13b2, 13b3) whose pitch angle is changeable, and is rotated by a fluid. The position detector (16) detects the rotational position of the propeller (13). The pitch controller (50) performs pitch control processing for changing the pitch angle depending on the position of each of the blades (13b1, 13b2, 13b3) specified by the rotational position of the propeller (13).

Description

technical field [0001] The present invention relates to a power generating device and a power generating system. Background technique [0002] Conventionally, propeller type power generating devices are widely known, which generate electric power by rotating a propeller using fluid such as wind and ocean current. A wind power generator converts mechanical energy of a propeller rotating by capturing wind force into electrical energy, for example, using a generator. [0003] In recent years, in order to eliminate differences in thrust and moment between blades in a propeller-type power generation device, a method for detecting the load on each blade to individually control each blade according to the load thus detected has been developed. blade pitch angle. For example, the prior art is disclosed in Japanese Patent Application Laid-Open No. 2003-113769. [0004] However, the technique disclosed in Japanese Patent Application Laid-Open No. 2003-113769 fails to individually c...
