Abstract

The invention provides a wind generating set remote on-line multi-mode health state monitoring and fault diagnosis system. The system comprises a wind speed/generated energy monitoring device, a temperature/vibration monitoring device, a voice frequency monitoring device and video monitoring device. The system is characterized by further comprising a lower computer and an upper computer, wherein the lower computer is connected with a wind generating set, and the upper computer is connected with a network client. Meanwhile, the audio and video technique is utilized, and remote observation of the operation state of the set is achieved. The system has the advantages of being simple in operation, and capable of achieving remote monitoring and remote diagnosis of faults.

Description

technical field [0001] The invention relates to an automatic monitoring and fault diagnosis system, in particular to a remote on-line multi-mode health state monitoring and fault diagnosis system for a wind power generating set. Background technique [0002] As a renewable new energy technology, wind power has developed rapidly in my country in recent years. By the end of 2012, my country had accumulatively installed 53,764 wind turbines, with an installed capacity of 75,324.2MW, taking a leading position in the world. Wind turbines are the key equipment for wind power generation. Most of them are arranged in relatively remote fields or on platforms tens of meters high at sea. The working conditions are very harsh and maintenance is very difficult. Cause very big accident, the loss is very huge. Therefore, in order to improve the safety, reliability and availability of wind turbine operation and reduce maintenance costs, it is urgent to develop a monitoring system and a fa...
