Embodiment Construction

[0022] The technical solution of the present invention will be further described below according to the accompanying drawings.

[0023] figure 1 The functions of each part of the online condition monitoring and fault diagnosis system of the wind turbine are illustrated. The online state monitoring and fault diagnosis system for wind power generating sets disclosed by the present invention is characterized in that: the online state monitoring and fault diagnosis system includes four parts: a monitoring device, a host computer, a central monitoring center, and a remote diagnosis center;

[0024] Among them, the monitoring devices are distributed and installed in each wind power generation unit. The process data mainly includes the instantaneous power input from other systems, the rotation state of the wind turbine yaw ring, the cabin temperature, wind speed, rotation speed, etc. After the process data is collected, it is directly sent to the host computer for supply. It is used...

Abstract

The invention discloses an online state monitoring and fault diagnosis system of a wind generator set. The system comprises four parts of a monitoring device, an upper computer, a central monitoring center and a remote diagnosis center, wherein the monitoring device is used for realizing signal acquisition and processing and communication with the upper computer; the upper computer is used for carrying out fine analysis on sample data and displaying various graph spectrums and fault analysis diagnosis and the like; the central monitoring center can monitor the state of fans in each wind fieldin a browsing manner; and the remote diagnosis center is used for periodically acquiring fan data of the wind field, periodically analyzing the state of the fans and carrying out fault analysis and location when alarming information sent by a certain fan is received.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment monitoring and fault diagnosis, and in particular relates to an online state monitoring and fault diagnosis system and method for a wind power generating set, which are used for wind farm owners to realize predictable state maintenance. Background technique [0002] Wind turbine is the main device of wind power generation and the core of wind power technology. The main monitoring components of wind turbines include main bearings, gearboxes, generators and towers. The main failure modes are: unbalance, misalignment, bearing and gear failure. Vibration measurement is one of the most commonly used and effective tools for wind turbine fault detection, analysis and diagnosis. [0003] At present, a considerable part of the fans in the wind farms that have been built in my country were purchased from abroad in the middle and late 1990s. The service life of these units is generally 15-20 y...
