状态监视系统和具有该状态监视系统的风力发电系统
Abstract:
一种风力发电机(10)的状态监视系统，设置有：传感器，检测偏航轴承的状态；监视器设备(80)，基于所述传感器的检测结果生成诊断参数；传感器，检测机舱和主轴的旋转角速度；以及数据服务器(330)，基于诊断参数诊断偏航轴承中的故障。当机舱的旋转角速度落入非零的第一预定范围内，并且主轴的旋转角速度落入第二预定范围内时，数据服务器(330)基于诊断参数从初始值的改变来诊断偏航轴承中是否有故障。
Abstract(English):

A state monitoring system of a wind power generator (10) is provided with: a sensor that detects the state of a yaw bearing; a monitoring apparatus (80) that generates diagnostic parameters on the basis of the detection results from this sensor; a sensor that detects rotation angular velocities of a nacelle and a main shaft; and a data server (330) that diagnoses a fault in the yaw bearing on the basis of the diagnostic parameters. The data server (330) diagnoses whether or not there is a fault in the yaw bearing on the basis of changes in the diagnostic parameters from initial values thereof when the rotation angular velocity of the nacelle falls within a non-zero first predetermined range and the rotation angular velocity of the main shaft falls within a second predetermined range.
