Title:
STATE MONITORING SYSTEM FOR WIND POWER GENERATOR
Document Type and Number:
Japanese Patent JP2022137940
Kind Code:
A
Abstract:
To provide a state monitoring system for a wind power generator having a function monitoring a state of a wind power generator and especially has a diagnosis function of a wind turbine such as a blade, which can improve certainty in damage detection and can reduce costs for system introduction.SOLUTION: A state monitoring system for a wind power generator monitors a state of a wind power generator by a windmill which is equipped with a windmill rotor having a plurality of wind turbines attached to a hub and rotating around the hub, and a generator generating power by rotations of the windmill rotor. The state monitoring system for a wind power generator is equipped with a wind turbine diagnosis unit that has a detecting function of vibrations of the wind turbine by vibration data from a vibration sensor, and a calculating function of a rotation speed or a rotation phase of the windmill rotor by acceleration data from an acceleration sensor.SELECTED DRAWING: Figure 1
