Alarm Generation Method for Wind Turbine Condition Monitoring System

Abstract

The invention relates to an alarm generating method of a wind driven generator monitoring system. The method comprises: a step S10 wind speed range setting in which more than two wind speed ranges are set by a control portion; a step S20 vibration signal acquisition in which a vibration signal at a position of a wind driven generator or at a position of a wind driven generator fitting is acquired; a step S30 vibration grade calculation in which the vibration grade of the vibration signal is calculated; a step S40 data storage in which effective vibration grade data is stored in a data storage portion; a step S50 in which alarm standard values of the various wind speed ranges are set; and a step S60 alarm signal generation in which the control portion compares the vibration grade of vibration signals acquired at a same time of a same wind speed range with the alarm standard values of various wind speed ranges in the same wind speed range and gives an alarm signal to a manager. By using the technical scheme of the invention, the state of the wind driven generator can be monitored in real time and beforehand ascertainment can be acquired before the wind driven generator generates faults or damages.

Description

technical field [0001] The invention belongs to the field of wind power generator monitoring systems, and in particular relates to an alarm generation method for a wind power generator state monitoring system. Background technique [0002] A wind power generation system that uses wind to generate electricity generally consists of a wind generator and a central control device that controls it. A wind turbine generally consists of blades that rotate by the wind, a nacelle consisting of a device that converts the rotational energy of the blades into electrical energy, a hub connecting the blades and the nacelle, and a tower supporting the nacelle. In addition, the wind power generator and the central control device are connected to each other in a wired or wireless manner. [0003] Keeping expensive wind turbines in good condition for long periods of time requires that fatal failures or damage be detected, repaired or otherwise taken before they occur. However, since it is im...

Problems solved by technology

However, since it is impossible to monitor wind turbines in real time by manual operation, it is necessary to monitor the specific parameters of wind turbines to realize the status monitoring of wind turbines, which is especially urgent for offshore wind turbines far away from land. At the same time, it is necessary to ensure the effectiveness of the alarm, but the current technological development is far from enough
