Description

Technical Field

[0001] The present invention relates to the technical field of model verification, and in particular to a method, device, equipment and medium for verifying a model of a floating wind turbine generator set. Background Art

[0002] Floating wind turbines are more complex than traditional fixed wind turbines. Floating wind turbines are strongly coupled systems involving aerodynamics, hydrodynamics, structural dynamics, control systems and mooring systems. Floating wind turbines rely on accurate integrated loads. In order to ensure the rationality of the design of floating units, it is necessary to establish an efficient and accurate coupling simulation model of the wind turbine-floating system for integrated load simulation. Limited by the complex multi-system coupling of floating units, the design of wind turbines in the industry is currently separated from the design of floating moorings. The whole machine manufacturer is responsible for the development of the whole machine, and the floating body designer is responsible for the floating body and mooring. Both parties verify the integrated load at the bottom of the tower. At the same time, the software in the wind power industry is good at aerodynamic analysis, while traditional marine engineering software is more advantageous in floating body and mooring analysis. The current conventional method of numerical simulation is to combine the wind turbine head model with the marine engineering floating body model to form an integrated model. The accuracy of the integrated numerical model is crucial to the entire floating design.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1 As shown, an embodiment of the present invention discloses a method for verifying a model of a floating wind turbine generator system, comprising:

[0044] Step S11: constructing an integrated model based on wind turbine parameters and floating body parameters of the floating wind turbine group.

[0045] In the embodiment of the present application, the first step is to integrate the floating wind turbine and the floating body into a model, and obtain the relevant wind turbine parameters and floating body foundation parameters. Specifically, it may include the shape and size of the whole machine and the floating foundation structure, the mass center of mass, the structural inertia information and the ballast mass arrangement, the mooring system parameters and arrangement, the floating body boundary element hydrodynamic file, etc. The whole machine parameters are provided by the wind turbine manufacturer, and the floating body and mooring parameters are provided by the floating body designer.

[0046] Step S12, performing a floating state check on the integrated model under preset static conditions to obtain corresponding floating state check results; the preset static conditions represent that the integrated model is in an environmental condition without wind, waves or current.

[0047] In the embodiment of the present application, during the process of performing a floating state check on the integrated model, it is necessary to first set the environmental conditions in which the integrated model is located to environmental conditions that characterize no wind, no waves, and no current based on static conditions, and it is necessary to shield external interference and only check the center of gravity and inertia information of the model. In a specific embodiment, the floating state check of the integrated model under preset static conditions to obtain corresponding floating state check results includes: setting the environmental conditions in which the integrated model is located based on preset static conditions to obtain the integrated model under environmental conditions of no wind, no waves, and no current; generating corresponding floating state check results according to the offset of the six degrees of freedom of the integrated model under environmental conditions of no wind, no waves, and no current. Specifically, the integrated model is first set under environmental conditions of no wind, no waves, and no current. Under these environmental conditions, it is necessary to make the six degrees of freedom of the integrated model have no offset to reflect the weight and inertia matching of the model, so as to carry out the next step of verification.

[0048] It is understandable that the floating state verification result obtained during the floating state verification process may indicate failure, that is, under windless, waveless, and currentless environmental conditions, the six-degree-of-freedom offset of the integrated model is not zero, and there is a mismatch in the weight and inertia of the model. At this time, the model needs to be adjusted, and then the floating state verification is performed. In a specific embodiment, the floating state verification of the integrated model under preset static conditions, after obtaining the corresponding floating state verification result, may also include: if the floating state verification result indicates failure, the center of gravity and inertia information of the integrated model are adjusted based on the six-degree-of-freedom offset corresponding to the floating state verification result, so as to re-perform the floating state verification on the adjusted integrated model. Specifically, in the process of adjusting the integrated model according to the floating state verification result, the center of gravity and inertia information of the model are adjusted according to the six-degree-of-freedom offset of the integrated model, so as to re-perform the floating state verification on the adjusted integrated model. In this way, an integrated model that passes the floating state verification without offset in the six-degree-of-freedom environment can be finally obtained.

[0049] Step S13: If the floating state verification result is characterized as passed, a damping verification is performed on the integrated model using a preset degree of freedom verification rule to obtain a corresponding damping verification result; the preset degree of freedom verification rule is a verification rule constructed based on six degrees of freedom directions.

[0050] Furthermore, if an integrated model that passes the floating state verification is obtained through the above steps, the next step of damping verification can be performed on the integrated model, specifically, the damping response of the integrated model is verified based on the six degrees of freedom. In a specific embodiment, the damping verification of the integrated model using the preset degree of freedom verification rules to obtain the corresponding damping verification results can include: determining the initial displacement in a degree of freedom direction using the preset degree of freedom verification rules to obtain the degree of freedom attenuation curve of the integrated model for the initial displacement; evaluating the attenuation period and damping based on the error between the degree of freedom attenuation curve and the preset attenuation curve, and generating corresponding damping verification results based on the evaluated attenuation period and damping. Specifically, in the process of damping verification, firstly, an initial displacement of a degree of freedom is given, and the other five degrees of freedom are free. After being released, the degree of freedom attenuation curve corresponding to the initial displacement can be obtained; then the degree of freedom attenuation curve is compared with the preset attenuation curve to evaluate the attenuation period and damping to obtain the corresponding damping verification results.

[0051] In a specific embodiment, after the damping check of the integrated model using the preset degree of freedom check rule and obtaining the corresponding damping check result, it may also include: if the damping check result characterization fails, the linear damping of the integrated model is corrected based on the evaluated attenuation period and damping, so as to re-perform the damping check on the corrected integrated model. Specifically, it can be understood that when the damping check fails, the integrated model needs to be adjusted, and the linear damping of the integrated model can be corrected with reference to the attenuation curve period and related damping characterized by the damping check result. In this way, an integrated model that meets the damping expectations can be finally obtained.

[0052] Step S14: If the damping verification result indicates passing, frequency verification is performed on the integrated model based on a preset structural resonance verification rule, and when the corresponding frequency verification result indicates passing, it is determined that the integrated model verification has passed.

[0053] In the embodiment of the present application, after the integrated model that has passed the floating state check and the damping check is obtained through the above steps, the frequency check is then performed to avoid structural resonance; and after the frequency check is passed, it can be determined that the corresponding integrated model check has passed, and subsequent working condition simulation can be performed.

[0054] In a specific embodiment, the frequency verification of the integrated model based on the preset structural resonance verification rules, and judging that the integrated model verification has passed when the corresponding frequency verification result indicates passing, may include: performing modal analysis on the integrated model based on the Campbell diagram to evaluate the difference between the wind turbine tower frequency and the wind rotor rotation frequency, and obtaining the corresponding frequency verification result; if the frequency verification result indicates that the difference between the wind turbine tower frequency and the wind rotor rotation frequency is greater than a preset threshold, then judging that the integrated model verification has passed. Specifically, during the frequency verification process, Campbell modal analysis may be performed to evaluate the difference between the wind turbine tower frequency and the wind rotor rotation frequency, and it is necessary to ensure that the difference between the wind turbine tower frequency and the wind rotor rotation frequency is greater than a preset threshold to avoid structural resonance.

[0055] In another specific embodiment, before determining that the integrated model has been verified, it may also include: using the integrated model to perform simulation processing based on the pre-set power generation conditions and shutdown conditions, so as to determine that the integrated model has been verified after the simulation process is completed normally. Specifically, before performing the integrated simulation of batch conditions, some special conditions can be selected in advance to use the integrated model that has passed the above verification process for simulation to check whether the simulation process is normal, such as whether there are abnormal conditions such as stalling and speed oscillation; after the simulation process is completed normally, the final integrated model can be used for subsequent integrated simulation of batch conditions.

[0056] It can be seen that the present application constructs an integrated model of the wind turbine and the floating body for a floating wind turbine, and verifies the integrated model based on the floating state, damping and frequency. The above verification process can effectively ensure the correctness of the integrated model, avoid model transmission errors caused by multi-disciplinary and multi-unit cross-design, and ensure the rationality of the design of the floating wind turbine.

[0057] like Figure 2 As shown, the embodiment of the present application discloses a method for model verification of a floating wind turbine generator set, comprising:

[0058] In the embodiment of the present application, it is first necessary to carry out integrated modeling of the wind turbine, specifically to obtain the parameters of the whole machine and the floating foundation of the wind turbine, including the shape and size of the whole machine and the floating foundation structure, the center of mass, the structural inertia information and the ballast mass arrangement, the mooring arrangement parameters, and the boundary element fluid force. Further, the whole machine model of the wind turbine is based on the actual project model of the whole machine. The floating foundation structure is generally a semi-submersible structure. Its column configuration has different types such as circular and rectangular according to different projects. In the integrated modeling, it is equivalent to a circular tube unit based on weight, cross-sectional area, and stiffness EI. According to the principles of cross-sectional area equivalence and stiffness equivalence, the diameter and wall thickness of the equivalent rod of the integrated model are obtained. The ballast water and equipment layout in the floating foundation can be equivalently modeled by point mass in the integrated model. In addition, the BEM (boundary element method) hydrodynamic parameters are obtained based on the marine engineering software to obtain the floating hydrodynamic data LIS file (a report file), and the hydrodynamic file is imported into the BEM module of the integrated software. Correspondingly, the mooring system and layout, the integrated model finalizes the displacement-tension stiffness curves of different mooring anchor chains, defines the position of the floating body fairlead hole and the anchor point position; defines the floating body flow coefficient and damping coefficient. In this way, an integrated model of the wind turbine can be obtained.

[0059] Furthermore, in the process of verifying the integrated model, a floating state verification is first performed. Under static conditions with no wind, no waves, and no current, it is necessary to ensure that the six degrees of freedom are not offset and remain at zero. If there is an offset and capsizing, the weight and inertia of the feedback model do not match, and it is necessary to return to check the floating foundation structure and the ballast water and equipment layout in the floating foundation, and adjust the model's center of gravity and inertia information to ensure the correct floating state verification. Under static conditions, the floating state deviations of the six degrees of freedom are all kept within 0.1m, and the floating state of the whole machine can be considered normal. Then, further compare whether there is a deviation between the center of gravity coordinates of the integrated model and the given design coordinates. The specific floating state verification results can be shown as follows. Figure 3 As shown, there is an offset in the six degrees of freedom.

[0060] If the integrated model passes the floating state verification, the damping verification will continue. Specifically, the free attenuation analysis is performed on the six degrees of freedom, including surge, sway, heave, pitch, roll, and yaw. The free attenuation is to give an initial displacement of one degree of freedom, and the other five degrees of freedom are free. After releasing, the free attenuation curve of the degree of freedom is obtained. The initial displacements of surge, sway and heave can be set to 10m. The initial angles of pitch, roll and yaw can be set to 10 degrees. The obtained six-degree-of-freedom attenuation curve of the integrated model is compared with the floating design input attenuation curve. The error can be verified to pass within a reasonable range. The attenuation period and damping are evaluated in detail. The period can be obtained through the waveform, and the damping is identified using the time series modal recognition method:

[0061] ;

[0062] ;

[0063] In the formula, 𝐴 𝑖 and 𝐴 𝑖+𝑘 are the amplitudes of the 𝑖th and 𝑖 + 𝑘th peak processes, respectively, and 𝜉 is the damping ratio.

[0064] If there is a deviation between the period and the damping, the linear damping correction is performed on the integrated model again, and the mooring system settings are checked at the same time until the requirements are met. The specific heave free attenuation verification results, that is, the damping verification results, can be as follows: Figure 4 As shown, there is a deviation between the attenuation curve obtained by the test and the attenuation curve of the floating design input.

[0065] If the integrated model passes the damping check, the frequency check (i.e. modal check) is continued, and Campbell modal analysis is performed to evaluate whether the tower frequency of the whole machine is close to the rotor frequency. It is necessary to ensure that the tower frequency is at least 10% away from the 1P and 3P range of the whole machine frequency to avoid structural resonance. The specific frequency check results are as follows: Figure 5 As shown, the tower frequency is compared with the whole machine rotation frequency 1P and 3P. In addition, the integrated model can be time-checked during the process, specifically by selecting typical power generation conditions and shutdown conditions for integrated simulation to check whether there are any abnormalities in the simulation timing, such as stalling, speed oscillation, etc. If the frequency check passes and the timing check passes, the final integrated model can be used for batch condition simulation; and the relevant floating design specifications can also be used for batch condition simulation analysis.

[0066] It can be seen that the integrated modeling process of the floating wind turbine in the embodiment of the present application can be applied to most mainstream numerical analysis software in the offshore wind power industry. The integrated model of the wind turbine and the floating body for the floating wind turbine can be verified based on the floating state, damping and frequency. The above verification process can effectively ensure the correctness of the integrated model, avoid model transfer errors caused by multi-disciplinary and multi-unit cross-design, and ensure the rationality of the design of the floating wind turbine.
