The present disclosure relates to a method and a system for repairing a wind generator based on weather information. According to an exemplary embodiment of the present disclosure, it is possible to effectively calculate a repairing time of the wind generator based on weather information.

System and method for repairing wind generator based on weather information

A wind farm supervision monitoring system includes: a data collection unit configured to collect data about a status monitoring of each wind turbine from at least one site server; an abnormality status detection unit configured to detect an abnormality status of each wind turbine based on the collected data about the status monitoring and issue an alarm; a wind data management unit configured to early detect a fault of each wind turbine and or monitor performance of each wind turbine based on the data about the status monitoring or the data about the abnormality status; and a supervision unit configured to manage a turbine operation status and operation and maintenance of each wind turbine and provide information for establishing an operation and maintenance plan for the detected abnormality status of the wind turbine.

Wind farm supervision monitoring system

Disclosed herein is a vibration monitoring and diagnosing system for monitoring conditions of a wind power generator and diagnosing a defective portion thereof using vibration characteristics obtained from acceleration sensors mounted to the wind power generator. A vibration-based defect detecting method may include: collecting vibration data of the wind power generator using the plurality of sensors; extracting a first characteristic value of a time domain based on the vibration data; extracting characteristic values in one or more frequency bands for a location of each sensor in a frequency domain or an envelope frequency domain if the first characteristic value is greater than a preset alarm setting value; and determining that a defect is present when at least one characteristic value of the characteristic values is greater than a preset normal value.

Vibration monitoring and diagnosing system for wind power generator

An apparatus for diagnosing abnormal operation of a rotor. The apparatus includes a first sensor provided around a shaft in order to detect vibration occurring while the shaft provided in a rotor axially rotates, a second sensor to generate a periodic pulse signal over time whenever the shaft rotates once, and a controller to determine an operation state of the rotor by receiving signals detected by the first and second sensors. When an aperiodic pulse signal is detected in the rotor, the controller determines a position of the rotor at which the aperiodic pulse signal is generated, and a display indicates the position of the rotor in which the aperiodic pulse signal is generated, according to information calculated by the controller.
