Embodiment Construction

[0045] In the following, the invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0046] refer to figure 1 , is a single structure diagram of a wind power tower vibration monitoring system according to an embodiment of the present invention.

[0047] As mentioned above, the technical solution of the present invention can be introduced from two levels of monomer and multi-body.

[0048] The vibration monitoring system of the present invention can monitor multiple wind power towers, but the monitoring subsystems or hardware components arranged on each wind power tower are the same.

[0049] The single body refers to the composition and principle of the monitoring subsystem arranged on each wind power tower, see figure 1 .

[0050] For each wind power tower, the monitoring system includes an on-site scanning unit, a local data processing unit and a vibration layout output unit;

[0051] The on-site scanning unit communica...

Abstract

The invention provides a wind power tower vibration monitoring system and a monitoring method thereof. The system comprises a remote centralized control platform, a field scanning unit, a local data processing unit and a vibration layout output unit; the field scanning unit obtains tower structure data of a target wind power device; the local data processing unit generates a feedback signal; the field scanning unit adjusts a scanning path based on the feedback signal; the vibration layout output unit outputs a tower vibration layout sampling map; based on the tower layout sampling map, a plurality of vibration sensors are arranged on a tower of the target wind power device; and the remote centralized control platform determines the weakest part of the tower based on multiple groups of vibration sensing data obtained in multiple sampling periods and the tower vibration layout sampling map. The method further comprises the steps of re-obtaining the tower vibration layout sampling map of the wind power tower and re-determining the weakest part of the tower. According to the invention, visual modeling, vibration monitoring layout and vibration weak position identification of the wind power tower can be realized.

Description

technical field [0001] The invention belongs to the technical field of wind power data monitoring, and in particular relates to a wind power tower vibration monitoring system, a monitoring method thereof, and a visualization terminal for realizing the method. Background technique [0002] In recent years, with the rapid development of the wind power industry, the rated power of the wind turbine, the weight of the nacelle, the height of the tower, and the length of the blades have continued to increase. Structure, an important issue following this change is the structural vibration safety of the fan during operation, and the wind-induced vibration of the fan is more prominent. [0003] Vibration monitoring is an effective means of monitoring the transmission chain of wind turbines. Among them, online vibration monitoring can realize 24-hour uninterrupted monitoring of the transmission chain of the unit, obtain real-time tracking data of the entire life cycle of the transmissi...
