On-line monitoring and instant warning and fault diagnosis system of wind generating set

Abstract

The invention discloses an on-line monitoring and instant warning and fault diagnosis system of a wind generating set. The on-line monitoring and instant warning and fault diagnosis system is composed of a lower computer (1) and an upper computer (5), wherein the lower computer (1) is installed on the wind generating set and is in communication with the upper computer (5) through a wired or wireless network. When the on-line monitoring and instant warning and fault diagnosis system works, the upper computer (5) transmits a start instruction to the lower computer (1), and then the lower computer (1) starts to collect signal data, carries out on-line instant warning on abnormalities and faults and stores signals or signal feature information; the upper computer (5) receives and stores the signals uploaded by the lower computer (1) or the signal feature information uploaded by the lower computer (1), analyzes and processes the signals or the signal feature information and generates various report forms according to needs. The on-line monitoring and instant warning and fault diagnosis system can carry out on-line instant warning and trend analysis on the operating state of the wind generating set and carry out forecasting and early warning on the potential faults, and has significant value for reducing sudden faults of the wind generating set, reducing loss caused by standby and the like.

Description

technical field [0001] The invention relates to the technical field of state monitoring and fault diagnosis of wind turbines, and especially designs an online monitoring, instant alarm and fault diagnosis system for wind turbines. Background technique [0002] Faults during the operation of wind turbines are one of the keys that affect the benefits of wind power operating companies. Generally speaking, the operation failure of wind turbines is the key factor that determines whether the wind turbine can operate stably for a long time, and its mechanism is complex and involves many factors. At present, the operation and maintenance of wind farms mainly use the monitoring of the main control system of the unit and regular inspections to understand the operating status of the unit. Due to the large amount of information that constitutes the operating status of the accessories, the calculation and processing process is complex, especially for the processing of massive data obtai...
