System and method for remote real-time state monitoring and intelligent failure diagnosis of wind turbine generators

Abstract

The invention relates to a technology for examining and maintaining wind turbine generators, in particular to a system and a method for the remote real-time state monitoring and the intelligent failure diagnosis of the wind turbine generators. The problems that the existing technology for examining and maintaining the wind turbine generators cannot ensure the examining and maintaining effect, cannot timely find the internal failure, the sudden failure and the hidden failure trouble of the wind turbine generators and requires a high examining and maintaining cost are solved. The system for the remote real-time state monitoring and the intelligent failure diagnosis of the wind turbine generators comprises state monitoring equipment, a site monitoring and failure diagnosis center and a remote monitoring and failure diagnosis center, wherein the state monitoring equipment comprises an accelerated vibration sensor, a rotating speed sensor, a current sensor, a camera and an on-line automatic analysis and diagnosis instrument; the site monitoring and failure diagnosis center comprises a site server and a site PC (Personal Computer). The system and the method are suitable for all types of wind turbine generators.

Description

technical field [0001] The invention relates to the overhaul and maintenance technology of wind turbines, in particular to a system and method for remote real-time state monitoring and intelligent fault diagnosis of wind turbines. Background technique [0002] my country has a vast territory and huge reserves of wind power resources. With the strong support of the state, my country's wind power industry has achieved rapid development for many years, and the installed capacity and power generation of wind power have ranked first in the world for three consecutive years. But at the same time, because the operation of wind power is greatly affected by the wind, and has the characteristics of intermittent, fluctuating, and random, after a period of time when large-scale wind power is connected to the grid, it is inevitable that wind turbine failures will occur, resulting in Wind turbines are abnormally shut down for maintenance, which seriously reduces power generation efficien...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems that the existing wind turbine inspection and maintenance technology is difficult to ensure the inspection and maintenance effect, the internal faults, sudden failures and hidden troubles of the wind turbine cannot be found in time, and the maintenance and maintenance costs are high, the invention provides a wind power generator. System and method for remote real-time state monitoring and intelligent fault diagnosis of unit
