Description
Technical Field
The invention relates to the field of wind power generation, in particular to a method and related equipment for inhibiting vibration of a wind driven generator blade.
Background
During the hoisting process and service period of the wind driven generator, due to unpredictable changes of wind condition environments of machine sites, corresponding safety protection actions such as heavy wind cut-out protection, shutdown protection and the like are required to be executed in a targeted manner under certain special working conditions.
The blades are important components of wind driven generators, and in recent years, as the length of the blades continues to increase, the corresponding structural strength and structural rigidity are gradually reduced due to the limitations of material properties and cost. The wind driven generator with the long blades is easier to generate blade vortex-induced vibration under certain special working conditions, and the safety operation of the wind driven generator is seriously threatened.
At present, methods of installing a turbulence device or a vortex generator, changing the blade pitch angle and the like are mainly adopted in the industry to eliminate the vortex-induced vibration of the blade.
For the vortex-induced vibration device added in the hoisting stage, the vortex-induced vibration generated by the blades in the running process of the unit cannot be protected after the unit is hoisted, and for the method for installing the blade vortex-induced vibration generator, although the blade vortex-induced vibration can be reduced in the running process of the unit, the additional installation cost and the maintenance cost are required to be increased.
For the method for changing the blade pitch angle, the existing scheme adopts a uniform pitch control instruction, and the blade pitch angle is always consistent, so that the impeller is caused to rotate with a certain probability while the vortex-induced vibration of the blade is relieved, the impeller can normally work when the impeller is unlocked and the wind speed is smaller, and the scheme cannot be safely carried out in a high wind state or in a maintenance working condition of impeller locking. And in the strong wind state, the multi-blade unified pitch (the pitch angle is not at the pitch-withdrawing position) possibly causes the overspeed risk caused by sudden increase of the rotating speed of the unit, and the maintenance working condition of impeller locking cannot perform the unified pitch-changing action because the impeller is not allowed to rotate, otherwise, the impeller locking device is possibly blocked.
Therefore, the mode in the prior art cannot effectively eliminate the vortex-induced vibration of the blade.

Referring to fig. 2, fig. 2 is a flowchart of a method for suppressing vibration of a wind turbine blade applied to the electronic device 100 of fig. 1, and the method includes steps described in detail below.
S201: and when a command for eliminating the blade vortex-induced vibration signal of the wind turbine generator is received, judging whether the wind turbine generator is in a preset state or not.
The preset state represents a state of the wind turbine generator set meeting adjustment.
S202: and when the wind turbine generator is in a preset state, determining each blade in the wind turbine generator.
S203: each blade is numbered.
S204: for each blade, a pitch control amount is determined based on the number of the blade.
S205: and adjusting the pitch signal of the corresponding blade based on the pitch control amount.
In a certain Reynolds number range, the karman vortex street phenomenon is generated when fluid transversely flows through the column. Assuming that the fluid flow velocity is v, the vortex shedding frequency is f, the characteristic length of the cylinder is D, and the strouhal number Sr is almost unchanged to a constant value within a certain reynolds number range, the following formula exists:
therefore, the projection of the section of the blade on the separation surface can be continuously changed by changing the pitch angle, so that the characteristic length D is acted, the shedding frequency f of the vortex shedding from the blade is continuously changed, the structural mode of the blade cannot be continuously excited by the shed vortex, and the effect of destroying the vortex-induced vibration condition of the blade is achieved.
When the wind turbine receives a blade vortex-induced vibration signal elimination instruction, whether the current wind turbine meets an elimination state is required to be judged, namely whether the wind turbine is in a preset state is judged, and if the wind turbine is not in the preset state, the wind turbine does not respond to the received blade vortex-induced vibration signal elimination instruction.
When the wind turbine generator is in a preset state, a pitch strategy is determined, and pitch signals of each blade of the wind turbine generator are adjusted based on the pitch strategy, so that the vortex-induced vibration signals of the blades are restrained.
Specifically, the pitch signal may be a pitch position, that is, the pitch position of the blade may be adjusted, and the pitch signal may also be a pitch speed, that is, the pitch speed of the blade may be adjusted.
In another example, when the wind turbine is in a preset state, a pitch control amount of each blade of each wind turbine may be determined, and a pitch speed of each blade is adjusted based on the pitch control amount of each blade, so as to implement suppression of vortex-induced vibration signals.
Because the wind turbine generator system includes a plurality of blades, in order to improve vortex-induced vibration suppression's effect, number for each blade to based on the serial number of blade, confirm that each blade is to the control amount of meeting an emergency oar, the control amount of changing oar of each blade is all different. And each blade is adjusted according to the corresponding variable pitch control quantity, and the generation of the independent variable pitch control quantity can ensure that the equivalent blade pitch angle theta e in the impeller plane at any moment is the blade pitch angle in the initial state (zero moment), so that the equivalent blade pitch angle is not changed by the vibration suppression strategy.
When a command for eliminating a blade vortex-induced vibration signal of a wind turbine generator is received, various implementation modes for judging whether the wind turbine generator is in a preset state are provided, and in one implementation mode, as shown in fig. 3, the method comprises the following steps:
s201-1: and when a command for eliminating the blade vortex-induced vibration signal of the wind turbine generator is received, determining whether the wind turbine generator is in a power-off state.
S201-2: and when the wind turbine is in the non-outage state, determining whether the wind turbine is in the shutdown state.
S201-3: if the wind turbine generator is in the shutdown state, determining that the wind turbine generator meets the preset state.
When the wind turbine is in a power-off state or the wind turbine is in a non-stop state, the pitch signals of all blades of the wind turbine are not required to be adjusted.
There are various implementations of determining the pitch control amount based on the number of blades for each blade, and in one implementation, as shown in fig. 4, the method includes the steps of:
S204-1: the suppression gain, the impeller rotation period, and the phase compensation value are determined.
S204-2: the total number of blades is determined.
S204-3: after determining that the instruction for eliminating the blade vortex-induced vibration signals of the wind turbine generator is received, the accumulated time for the wind turbine generator to meet the preset condition is calculated.
S204-4: the pitch control amount of the blade is determined based on the suppression gain, the impeller rotation period, the phase compensation value, the cumulative time, the total number of blades, and the number of blades.
Specifically, the pitch control amount satisfies the following formula:
wherein G damp is the suppression gain, tr is the impeller rotation period, tc is the accumulated time, For the phase compensation value, n is the number of the blades, and k is the total number of the blades.
The value of G damp can be pi/18, and the value of the rotation period of the impeller can be 120.
The impeller rotation period is set, when the impeller rotation period is set to be larger, the adjustment amount of the blades in unit time is smaller, when the impeller rotation period is set to be smaller, the adjustment amount of the blades in unit time is larger, and the impeller rotation period can be set specifically and selectively based on actual conditions.
When (when)When the phase compensation value is equal to pi/2, the pitch control amount satisfies the following formula:
in a mode of adjusting the pitch signal of the corresponding blade based on the pitch control amount, the pitch control amount may be increased for each blade based on the initial parameter of the blade.
Illustratively, the pitch control amount is an angle control amount, and when the initial parameter is an initial angle, the control blade increases the angle control amount on the basis of the initial angle. When the initial parameter is the initial speed, the variable pitch control quantity is converted into the variable pitch speed control quantity, and the speed control quantity is increased on the basis of the initial speed by controlling the blades.
Finally, through the method, the impeller cannot rotate in the process of changing the pitch and inhibiting the vibration, and the safe execution of the unit under various working conditions (suitable for the high wind cutting-out and maintenance states) can be ensured; the blade aerodynamic attack angle change in the impeller rotating process can be simulated by adopting the independent pitch-changing action, the consistency of the large-size separation vortex along the height is destroyed, the shedding frequency and the ordering of the large-size separation vortex behind the blades and the tower barrel are disturbed, the abnormal vibration phenomenon of the blades of the large-impeller wind driven generator is restrained, and the inhibition of the abnormal vibration of the blades is realized.
