Description

Online vibration state monitoring device of wind generating set

Technical Field

The utility model relates to a wind generating set technical field especially relates to a wind generating set online vibration state monitoring devices.

Background

The wind driven generator generates electricity by utilizing wind power, is a green energy source and is generally arranged in a remote wind power plant; the wind turbine generator is located in the tower top cabin, and the difficulty in maintenance and repair of the wind turbine generator is high. Wind turbine installations are prone to failure, including gear bearing failure in the gearbox, bearing failure in the generator, lubrication system failure, main shaft impeller failure, etc. Once the fault occurs, the unit is shut down, great loss is caused, and the difficulty and the cost of the maintenance and the repair of the unit are high, so the state monitoring and the fault diagnosis of the wind driven generator are very important for ensuring the normal operation of equipment and improving the utilization rate of the equipment.

In general, there are two ways of performing condition monitoring, off-line and on-line. And off-line, namely, the equipment state is detected beside the unit by manually carrying a detection instrument. And installing a corresponding monitoring device in the unit on line to continuously acquire important equipment state parameters in real time. The off-line mode is difficult to get into the engine room due to the fact that personnel need to ascend, the wind turbine generator is often scattered in a large area, and the on-site expansion of maintenance personnel is not facilitated, especially for the offshore wind turbine generator, the approaching of unit equipment is a difficult matter, or the cost is high, the detection efficiency is low, and real-time monitoring cannot be carried out. On-line monitoring is not limited by environmental conditions and the like, and is the most suitable mode for monitoring the state of the wind power generation equipment.

At present, wind power equipment is provided with an online vibration monitoring device of a main transmission bearing. The potential faults of partial equipment can be found, but the state of a certain aspect or local equipment of the equipment is only monitored, the monitoring frequency and the data volume are not enough, so that the large faults of the fan and safety accidents happen occasionally and are difficult to avoid. Lack fan operation real-time status data, consequently can't know the historical operating condition of fan, can't in time discover to early trouble, also can't know the current trouble degree and position of fan, also can't make accurate prediction to the next degradation trend of fan trouble
