Problems solved by technology

The operation and maintenance of wind turbines is difficult, the monitoring system is backward, and the lack of failure mechanism analysis and countermeasures results in timely maintenance and forced shutdown when the wind conditions are good, which brings huge economic losses to wind power operators. The unit maintenance system improves the equipment utilization rate of wind turbines and reduces operation and maintenance costs

example 1

[0031] Example 1: A wind turbine alarmed that the high-speed shaft was running abnormally. After dismantling and checking, it was found that the high-speed shaft bearings were glued, which did not cause other components to fail. The maintenance cost was about 20,000 yuan. However, due to the full power generation period during the maintenance period, As a result, the loss of power generation in the full period is 200,000.

[0032] If the forward-looking maintenance strategy is adopted, on the one hand, the maintenance that avoids the full period can be realized according to the wind resource distribution data unit (referred to as module 4). On the other hand, the cause of bearing gluing may be overheating of the bearing due to excessive load or failure of temperature control. Here, the excessive load can be judged by the load spectrum measurement unit (referred to as module 1). If the bearing has been operating under the condition of exceeding the design load for a long time, ...

Abstract

The invention relates to a load spectrum determination and proactive maintenance system of a wind generating set. The load spectrum determination and proactive maintenance system comprises a data acquisition and monitoring control system and is characterized in that a main engine of the data acquisition and monitoring control system is in connection with a main control system of the wind generating set for communication so as to obtain running and alert data of the wind generating set; the main engine also is in connection with a load spectrum determination unit of the wind generating set for communication so as to determine the running load spectrum of the wind generating set, is in connection with a transmission chain acquisition unit of the wind generating set for communication so as to acquire vibration, noise and displacement of a transmission chain of the wind generating set, and is connected with a wind power plant wind-resource distribution data unit. By detecting the running state of wind driven generators, the system establishes a running condition database, studies the mechanism of main failure forms of a fan, and realizes proactive maintenance for the wind generating set.

Description

technical field [0001] The invention relates to a load spectrum measurement and forward-looking maintenance system of a wind power generating set. Background technique [0002] The advantages of new domestic clean energy are becoming more and more obvious, and the installed capacity of wind turbines continues to rise. With the increase of the operating time of the units, the units have gradually begun to have component problems (such as blades, main shaft bearings, controllers, etc.). The operation and maintenance of wind turbines is difficult, the monitoring system is backward, and the lack of failure mechanism analysis and countermeasures results in timely maintenance and forced shutdown when the wind conditions are good, which brings huge economic losses to wind power operators. The unit maintenance system improves the equipment utilization rate of wind turbines and reduces operation and maintenance costs. Contents of the invention [0003] One of the purposes of the p...
