Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The fuselage solution of the present application is based on the fact that the first order natural frequency NF1 and the second order natural frequency NF2 of the flexible tower can be as low as 0.1Hz to 0.2 Hz. The generator set has a stage of coupling with NF1 in the process of increasing the impeller rotating speed from the grid-connected rotating speed to the rated rotating speed, the corresponding impeller rotating speed is recorded as RS1, and whether the frequency coupling condition exists can be judged by monitoring the real-time rotating speed of the impeller. During the full-time period of the wind turbine generator, when the wind power is further enhanced, the generator set can control the rotating speed of the generator set through the variable pitch action to prevent overspeed, and at the moment, if the variable pitch action frequency is coupled with NF1 or NF2, fatigue damage of the tower can be caused, so that the parameter of the pitch angle can be monitored to judge whether the variable pitch action frequency is coupled with NF1 or NF 2. In some special cases, such as vortex-induced resonance, unbalanced impeller and the like, whether the coupling condition exists can be judged by directly monitoring the frequency characteristic of tower barrel shaking. According to the above characteristics, the present application specifically proposes the following specific embodiments:

The power generation equipment is provided with a main controller which is used for executing operation control operation on the power generation equipment and is also used for detecting the rotating speed and the pitch angle of an impeller on the power generation equipment.
Therefore, the vibration sensor groups are respectively arranged at the top and the middle of the flexible tower drum and are determined by the first-order vibration mode and the second-order vibration mode of the flexible tower drum, the vibration modes are shown in figure 4, when the flexible tower drum is at a selected position, the tower drum is maximum in shaking amplitude, and the frequency characteristics of two-order vibration modes can be monitored most effectively.
As shown in fig. 1, the operation state monitoring method provided by this embodiment is applied to an electronic device disposed on the wind turbine generator, where the electronic device may be understood as a computer device or a controller having data calculation and information processing capabilities, and the operation state monitoring method includes the following steps:
and S1, collecting the state parameters of the wind turbine generator.
The state parameters of the present embodiment include the vibration parameters detected by the vibration sensor group and the operation parameters of the wind turbine generator system, and the operation parameters include the impeller rotation speed and the pitch angle of the power generation equipment. In the acquisition, the vibration parameters detected by the vibration sensor group are acquired from the vibration sensor group, and in addition, the operation parameters are acquired from a main controller of the power generation equipment.

On the basis of obtaining the state parameters, the vibration parameters or the vibration parameters and other operation parameters are used for operation processing to obtain the operation state of the wind turbine generator, prompt information is timely sent to operation and maintenance personnel in case of coupling vibration, and the wind turbine generator can be prevented from being damaged by the coupling vibration through intervention of the operation and maintenance personnel.
According to the method, the obtained running state comprises the first coupling vibration, the second coupling vibration and the tower vibration, and the specific scheme is as follows:
1. and obtaining a corresponding running state, namely the first coupling vibration, by processing the rotating speed and the vibration parameters of the impeller. The dangerous range of the impeller rotating speed is set according to NF1 as [ RS1-RS1 × 10%, RS1+ RS1 × 10% ], and is marked as [ RS1-, RS1+ ], and the monitoring logic is as follows:
the real-time monitoring of the impeller rotating speed is realized according to the obtained operating parameters, when the rotating speed enters the interval of [ RS1-, RS1+ ], timing is started, the real-time rotating speed RSi is recorded, the average rotating speed RSm in 60s is calculated by taking 60s as time limit,
wherein,
i-recorded ith rotation speed;
the number of revolutions recorded in n-60 s is equal to the time x sampling frequency.
Further, when the timing is started, the timing is cancelled when the RSi < RS1-RS1 x 15% or RSi > RS1+ RS1 x 15%, and the process is repeated when the next RSi falls into the interval of [ RS1-, RS1+ ].
And if the obtained RSm is positioned in the interval of RS1-RS 1+, a warning is sent to a main control center and a remote monitoring center of the unit, the frequency conversion of the impeller and NF1 have resonance risks, and the unit can take protective measures. And if the RSm is positioned outside the interval of RS1-RS 1+, the unit continues to normally operate without sending a warning.
2. And processing the pitch angle and the vibration parameter to obtain a corresponding running state, namely the second coupling vibration. In particular, the frequency coupling induced by the pitch action is monitored.

In this embodiment, NF1 is monitored by a vibration sensor group mounted on top of the flexible tower, and NF2 is monitored by a vibration sensor mounted in the middle of the flexible tower. Taking the example of NF1 monitoring, a flexible tower is more likely to cause resonant coupling during shutdown than a rigid tower.

2) fig. 9 is a diagram showing a vibration spectrum in a normal case, and fig. 10 is a diagram showing a case where there is an abnormal vibration coupled to the tower first-order natural frequency NF 1. The fourier transform results were judged to be within the frequency range of [ NF1-NF1 × 10%, NF1+ NF1 × 10% ], denoted as [ NF1-, NF1+ ], as shown in fig. 10 as the frequency range between the two dashed lines.
