MARINE STRAIGHT WING/VERTICAL SHAFT TYPE WIND POWER GENERATION DEVICE

摘要

A marine straight wing/vertical shaft type wind power generation device enabling a windmill from being damaged even when a ship is oscillated. The ship comprises a straight wing/vertical shaft type windmill (2), a generator (3) driven by the windmill (2), a brake means (8) forcibly stopping the windmill (2), an anemometer (11), a gyro sensor (12) for measuring the tilting angular velocity of the windmill (2) at the rotating shaft (15), and a control means (10) controlling the brake means (8) and servo controller (13). When a wind velocity exceeds an upper limit set value (for example, 25 m/sec) and the tilting angular velocity of the rotating shaft (15) exceeds a set value (for example, 5°/sec), the brake means (8) is operated to forcibly stop the windmill (2).
