Description

Technical Field

[0001] The present application relates to the field of offshore wind power engineering, and in particular, to a method and device for determining the expected life of an offshore wind power steel structure, a storage medium and an electronic device. Background Art

[0002] As an important part of renewable energy, the stability and durability of offshore wind power structures are crucial to ensuring the continuous supply of energy. Offshore wind power steel structures, including towers, foundations and blades, are exposed to the marine environment for a long time and are subject to a variety of corrosion factors such as salt spray, humidity, temperature changes and biological attachment. Therefore, accurately estimating the life of offshore wind power steel structures is of great significance for the planning, maintenance and cost control of wind farms.

[0003] Traditional life prediction methods mainly rely on empirical formulas or simple models, which are usually based on historical data and general assumptions, such as the constancy of corrosion rate. However, these methods often ignore the dynamic changes in corrosion rate, such as changes in rate caused by changes in environmental conditions (such as temperature, humidity, salinity, etc.) or changes in material properties (such as coating degradation, metal fatigue, etc.), resulting in inaccurate life prediction results. Although some existing technologies have attempted to consider the impact of corrosion factors, they have not fully considered tracking changes in corrosion rates in practical applications, resulting in the inability to adjust the estimated life expectancy in a timely manner, and there is a problem of inaccurate estimation of the expected life expectancy of offshore wind power steel structures.

Taking running on a mobile terminal as an example, Figure 11 is a hardware structure block diagram of a mobile terminal for determining the expected life of an offshore wind power steel structure according to an embodiment of the present application. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor (Central Processing Unit, MCU) or a programmable logic device (Field Programmable Gate Array, FPGA)) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal.

[0030] In this embodiment, a method for determining the expected life of an offshore wind power steel structure is provided. Figure 2is a flow chart of a method for determining the expected life of an offshore wind power steel structure according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0031] Step S202: obtaining a current corrosion rate obtained by real-time monitoring of the offshore wind power steel structure;

[0032] Step S204: Calculating the corrosion allowance of the offshore wind power steel structure based on the current corrosion rate;

[0033] Step S206: Determine the expected life according to the allowable corrosion amount of the offshore wind power steel structure corresponding to the corrosion allowance.

[0034] Through the above steps, the current corrosion rate is obtained by real-time monitoring of the offshore wind power steel structure; the corrosion allowance of the offshore wind power steel structure is calculated based on the current corrosion rate; and the expected life is determined according to the allowable corrosion amount of the offshore wind power steel structure corresponding to the corrosion allowance. The life of the offshore wind power steel structure can be estimated based on the corrosion rate. Specifically, the corrosion rate is obtained in real time using an online monitoring system, and the dynamic changes of the corrosion rate are considered and the corrosion allowance and expected life are calculated in combination with a formula. This can more accurately reflect the corrosion of the steel structure, improve the accuracy of the life estimation, and thus solve the problem of inaccurate estimation of the expected life of the offshore wind power steel structure, and improve the accuracy of the expected life of the offshore wind power steel structure.

[0035] It should be noted that the above corrosion rate can be understood as the degree of corrosion of the underwater offshore wind power steel structure per unit time, for example, expressed in terms of thickness loss or mass loss per unit time.

[0036] The above corrosion allowance indicates the remaining thickness or mass of the offshore wind power steel structure after a certain period of corrosion.

[0037] The above expected lifespan represents the number of years that offshore wind power steel structures are expected to continue to be safely used, taking into account the corrosion rate.

[0038] In an exemplary embodiment, the corrosion allowance of the offshore wind power steel structure is calculated based on the current corrosion rate, including: determining the corresponding corrosion amount of the offshore wind power steel structure at a first monitoring moment based on a first formula, and determining the expected corrosion amount of the offshore wind power steel structure within a monitoring period based on a second formula, wherein the corrosion amount and the expected corrosion amount are both determined based on the structural parameters of the offshore wind power steel structure, and the monitoring period starts from the first monitoring moment; the corrosion allowance is determined by a first difference between the corrosion amount and the expected corrosion amount according to the original structural parameter values ​​of the structural parameters.

[0039] The amount of corrosion indicates the thickness or mass of the offshore wind power steel structure lost due to corrosion at the monitoring time. The expected amount of corrosion indicates the thickness or mass of the offshore wind power steel structure estimated to be lost due to corrosion during the monitoring period.

[0040] Among them, the first formula is D1 = K·T·C corr,0 , the second formula is Where D0 is the original thickness or mass of the steel structure (i.e. the original structural parameter value), C corr,i (i=0,1,...,n) is the corrosion rate monitored online, K is the coefficient constant, T is the age of the offshore wind power steel structure up to the time when the first corrosion rate is collected, and ΔT is the monitoring period of online monitoring.

[0041] It can be understood that the above structural parameters include, for example, thickness, mass, etc. The original structural parameter value of the structural parameter includes an original mass value or an original thickness value.

[0042] In an exemplary embodiment, the corrosion allowance is determined based on the original structural parameter value of the structural parameter and the first difference between the already corroded amount and the expected corrosion amount, including at least one of the following: the thickness is determined from the structural parameter and the corrosion allowance is determined based on the original thickness value of the offshore wind power steel structure and the second difference between the already corroded amount and the expected corrosion amount; the mass is determined from the structural parameter and the corrosion allowance is determined based on the original mass value of the offshore wind power steel structure and the third difference between the already corroded amount and the expected corrosion amount.

[0043] In an exemplary embodiment, the corrosion allowance is expressed as D=D0-D1-D2, wherein D0 is the original structural parameter value, D1 is the corroded amount, and D2 is the expected corrosion amount.

[0044] In an exemplary embodiment, determining the expected life according to the allowable corrosion amount of the offshore wind power steel structure corresponding to the corrosion allowance includes: obtaining a third difference between the original structural parameter value and the allowable corrosion amount; and determining the expected life based on a condition parameter in the preset condition when it is determined that the third difference satisfies a preset condition, wherein the preset condition is expressed as follows:

[0045]

[0046] D-D3 is the third difference, D0 is the original structural parameter value, D3 is the allowable corrosion amount, C corrF,j is the predicted corrosion rate obtained based on the corrosion rate prediction, m is the condition parameter, and ΔT is the monitoring period.

[0047] The process of determining the expected life span based on the condition parameters in the preset conditions may include, for example: obtaining the expected life span using the formula ΔT·m.

[0048] In an exemplary embodiment, obtaining the current corrosion rate obtained by real-time monitoring of the offshore wind power steel structure includes: determining the original thickness of the offshore wind power steel structure at the initial monitoring moment and the monitored thickness at the current monitoring moment; determining the monitoring time period between the initial monitoring moment and the current monitoring moment, and determining the thickness difference between the original thickness and the monitored thickness; determining the current corrosion rate according to the ratio of the thickness difference and the monitoring time period.

[0049] And / or, in one embodiment, it is also possible to determine the original quality of the offshore wind power steel structure at the initial monitoring time and the monitored quality at the current monitoring time; determine the monitoring time period between the initial monitoring time and the current monitoring time, and determine the quality difference between the original quality and the monitored quality; and determine the current corrosion rate based on the ratio of the quality difference and the monitoring time period.

[0050] Considering that the steel structures of offshore wind power are exposed to the marine environment for a long time and are very susceptible to corrosion, real-time monitoring of the corrosion rate can not only improve the safety of offshore steel structures for accurate assessment of the expected service life, but also facilitate subsequent maintenance and extend their service life.

[0051] Exemplarily, the present application provides some techniques or methods for monitoring corrosion rate, specifically including:

[0052] 1. Conduct regular inspections: Inspect the steel structure regularly and record signs of corrosion, such as rust, paint peeling, material thinning, etc.

[0053] 2. Use non-destructive testing technology to detect the corrosion state of steel structures. For example, ultrasonic probes can be used to detect defects such as wall thickness reduction caused by corrosion inside the material. Magnetic fields can be used to detect surface or near-surface defects such as cracks and corrosion. X-rays or gamma rays can be used to penetrate materials to detect internal corrosion. Or corrosion and other defects can be detected by generating eddy currents on the surface of the material.

[0054] 3. Electrochemical monitoring technology: The corrosion rate can be evaluated by measuring the polarization resistance.

[0055] 4. Coating monitoring technology: Use a coating thickness gauge to regularly measure the thickness of the coating to assess the wear and corrosion of the coating.

[0056] 5. Corrosion rate meter monitoring technology: A corrosion rate meter (such as weight loss method or depth measurement method) is installed on the structure to measure the corrosion rate regularly.

[0057] 6. Intelligent sensor monitoring technology: Use intelligent sensors (such as fiber optic sensors, wireless sensors) to monitor corrosion conditions in real time.

[0058] Furthermore, in addition to the above monitoring technologies, it is also possible to monitor marine environmental conditions, such as salinity, temperature, humidity, and currents, which are factors that affect the corrosion rate. Then, statistical analysis methods are used to analyze all the recorded monitoring data and predict future corrosion trends. During the analysis process, for example, computer simulation software can be used to simulate the corrosion process and predict the corrosion rate. It is also possible to regularly invite corrosion experts to conduct on-site assessments and provide professional advice.

[0059] Based on the monitoring results and the expected life span, maintenance activities such as coating repair, cleaning and anti-corrosion treatment can be carried out on offshore wind power steel structures to reduce the impact of corrosion on steel structures and extend the service life of steel structures.

[0060] Through the above methods, the corrosion rate of offshore wind power steel structures can be effectively monitored, and corresponding maintenance measures can be taken to extend their service life.

[0061] Obviously, the embodiments described above are only some embodiments of the present application, not all embodiments. In order to better understand the above method, the above process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present application, specifically:

[0062] In one embodiment, a process for determining life expectancy is proposed, comprising the following steps.

[0063] Step 1: Collect the corrosion rate. The corrosion rate of underwater steel structures can be monitored by an online monitoring system. corr,i (i=0,1,...,n), i represents the time series order.

[0064] Step 2: Calculate the corrosion allowance D using the following formula.

[0065]

[0066] Where D0 is the original thickness of the steel structure (i.e. the original structural parameter value), in mm, C corr,i (i=0,1,...,n) is the corrosion rate monitored online, K is the coefficient constant, T is the age of the offshore wind power steel structure until the first corrosion rate is collected, and ΔT is the monitoring period of online monitoring.

[0067] Step 3, calculate the expected life expectancy using ΔT·m, where m is a positive integer that satisfies the following formula:

[0068]

[0069] Where D3 is the minimum allowable thickness (i.e. allowable corrosion amount) under the condition of ensuring the safety of the steel structure, in mm. F , j is the corrosion rate C based on time monitoring corr,i (i=0, 1, ..., n) Estimated corrosion rates at different future monitoring period points (i.e., predicted corrosion rates obtained based on the corrosion rate prediction).

[0070] The above steps can also be used to continuously adjust estimated life expectancy over time.

[0071] Through the above-mentioned embodiments, when estimating the life of offshore wind power steel structures based on corrosion rate, real-time monitoring technology, dynamic adjustment mechanism and more complex calculation models can be integrated to improve the accuracy and practicality of the estimation. Specifically, by using an online monitoring system to obtain the corrosion rate in real time, the corrosion condition of the steel structure can be more accurately reflected. By considering the dynamic changes in the corrosion rate and combining specific formulas to calculate the corrosion allowance and expected life, the accuracy of the life estimation is improved. At the same time, the expected life is continuously adjusted over time to make the estimation result more in line with the actual situation.

[0072] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.
