[0032] In this embodiment, a method for executing a blade deicing operation is provided. Figure 2 is a flow chart of a method for executing a blade deicing operation according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0033] Step S202, determining a target heating unit according to the ice position and ice thickness on the fan blade, wherein the target heating unit is a heating unit to be operated, and the fan blade includes: a plurality of heating units;

[0034] It should be noted that the layout diagram of the fan blades and the heating unit is as follows Figure 3 shown.

[0035] Step S204, determining a target output voltage of the converter according to a target temperature of the target heating unit;

[0036] Step S206 , adjusting the output voltage of the converter to the target output voltage, so that the target heating unit receives the output voltage and performs a de-icing operation on the fan blade according to the output voltage.

[0037] Through the above steps, the target heating unit is determined according to the ice position and ice thickness on the fan blade, wherein the target heating unit is a heating unit to be operated, and the fan blade includes: multiple heating units; the target output voltage of the converter is determined according to the target temperature of the target heating unit; the output voltage of the converter is adjusted to the target output voltage so that the target heating unit receives the output voltage. That is, the embodiment of the present application can effectively heat the ice position and ice thickness on the fan blade by accurately controlling the output voltage of the converter, avoiding overheating and reducing energy waste. Therefore, it can solve the problem that the output voltage of the power supply is constant, which leads to high energy waste in the system.

[0038] Optionally, in order to better understand the above step S204, the above step S204 can be implemented in the following manner: determining the expected temperature of the target heating unit according to the ice coating thickness and the expected ice coating thickness; determining the target output voltage according to the expected temperature and the measured temperature of the target heating unit.

[0039] The embodiment of the present application provides a control strategy based on the target heating unit temperature feedback, which accurately controls the heating amount of the heating unit by adjusting the output voltage of the converter, thereby achieving an efficient and safe deicing effect. Specifically:

[0040] First, the system monitors the actual ice thickness on the blade and compares it with the expected ice thickness (ideally, the expected ice thickness is 0, i.e., no ice). Based on the difference in ice thickness, the system calculates the expected temperature that the target heating unit needs to reach to ensure that the ice can be effectively melted while avoiding damage to the blade material caused by excessive temperature.

[0041] Secondly, the system monitors the measured temperature of the target heating unit in real time and compares it with the calculated desired temperature. Based on the difference between the desired temperature and the measured temperature, the system calculates the target output voltage that the converter needs to adjust. This process usually follows Ohm's law and the power formula in physics, that is, P = U^2 / R, where P is power, U is voltage, and R is resistance. By adjusting the voltage U, the power P of the heating unit can be precisely adjusted to control its heat generation and reach the desired temperature.

[0042] The control strategy of the embodiment of the present application adopts a dual closed-loop feedback mechanism of temperature and ice thickness. That is, the system will continuously compare the difference between the current state and the target state, and dynamically adjust the control parameters, that is, the output voltage of the converter, according to these differences. This closed-loop control can ensure that the temperature and ice thickness of the heating unit are always close to the preset target values, thereby achieving accurate deicing effect.

[0043] Optionally, determining the expected temperature of the target heating unit according to the ice coating thickness and the expected ice coating thickness includes: determining a thickness difference between the ice coating thickness and the expected ice coating thickness, and determining a first expected temperature of the target heating unit according to the thickness difference; determining a temperature threshold of the target heating unit, and determining a first size relationship between the temperature threshold and the first expected temperature; when the first size relationship indicates that the temperature threshold is greater than or equal to the first expected temperature, determining the first expected temperature as the target expected temperature; when the first size relationship indicates that the temperature threshold is less than the first expected temperature, determining the temperature threshold as the target expected temperature.

[0044] In the embodiment of the present application, the desired temperature of the heating unit is dynamically adjusted according to the difference between the actual ice thickness and the desired (target) ice thickness, thereby achieving effective control of ice. Specifically:

[0045] The system obtains the actual ice thickness on the blade through the sensor. Then, the actual ice thickness is compared with the preset expected ice thickness to determine the difference between the two. According to the size of the difference, the PI controller determines the first expected temperature of the target heating unit, where the thicker the ice, the higher the expected temperature to speed up the deicing process; the thinner the ice, the lower the expected temperature to avoid overheating and energy waste.

[0046] Compare the temperature threshold with the first expected temperature; if the temperature threshold is greater than or equal to the first expected temperature, it means that the first expected temperature is within a safe range, and the system will use the first expected temperature as the heating target of the target heating unit; if the temperature threshold is less than the first expected temperature, it means that the first expected temperature calculated based on the ice thickness exceeds the safe temperature limit of the material. At this time, the system will use the temperature threshold as the heating target of the target heating unit to ensure safe operation.

[0047] It should be noted that the temperature threshold is a temperature upper limit preset based on the characteristics of the blade material, safe operating conditions of the heating unit, etc. This helps protect the blade material from damage or aging due to overheating.

[0048] Through the embodiments of the present application, the system can intelligently adjust the temperature of the heating unit, which not only ensures the deicing efficiency, but also takes into account the safety of the blade material and the economy of the system. It can effectively reduce unnecessary energy consumption, extend the life of the blades, and improve the safety and operating efficiency of the wind turbine. In practical applications, this method can significantly improve the intelligence level of the electric heating deicing system, making it more adaptable to complex and changing environmental conditions.

[0049] Optionally, the target output voltage is determined according to the expected temperature and the measured temperature of the target heating unit, including: determining the temperature difference between the expected temperature and the measured temperature, and determining the expected output voltage according to the temperature difference; determining the output voltage threshold of the inverter, and determining a second size relationship between the output voltage threshold and the expected output voltage; when the second size relationship indicates that the output voltage threshold is greater than or equal to the expected output voltage, determining the expected output voltage to be the target output voltage; when the second size relationship indicates that the output voltage threshold is less than the expected output voltage, determining the output voltage threshold to be the target output voltage.

[0050] The embodiment of the present application dynamically adjusts the target output voltage by comparing the difference between the expected temperature and the actual measured temperature, thereby ensuring that the temperature of the heating unit can accurately reach the expected value. Specifically:

[0051] First, the algorithm calculates the difference between the desired temperature and the current measured temperature of the target heating unit. This difference reflects the deviation between the heating unit temperature and the set target and is the basis for adjusting the heating power. Based on the temperature difference, the desired output voltage is calculated through a certain control logic (which can be PI control). This voltage value will be used as the target value to adjust the output of the inverter to achieve the desired heating effect.

[0052] Determine the relationship between the expected output voltage and the output voltage threshold; if the expected voltage is less than or equal to the maximum output voltage of the converter (i.e., the threshold), the expected output voltage can be directly controlled as the target output voltage; if the expected output voltage exceeds the maximum output voltage of the converter, i.e., the threshold is less than the expected output voltage, the converter cannot directly meet the expectation, and at this time, the algorithm uses the threshold as the target output voltage.

[0053] It should be noted that the voltage threshold is a limit on the maximum output voltage that the converter can provide, and is usually determined by the hardware performance of the converter. In the embodiment of the present application, this threshold is set to the DC bus voltage divided by the square root of 2.

[0054] Through the embodiment of the present application, the system can ensure accurate temperature control of the heating unit and avoid exceeding the hardware limit of the converter, thereby ensuring the stability and safety of the system. In addition, this method can also effectively reduce overheating, protect the blade material from damage, and improve the operating efficiency and reliability of the wind turbine.

[0055] Optionally, determining the target output voltage of the inverter based on the target temperature of the target heating unit also includes: when there are multiple target heating units, determining the expected output voltage corresponding to each target heating unit; determining the expected output voltage with the largest value and the output voltage threshold of the inverter; determining a third size relationship between the output voltage threshold and the expected output voltage with the largest value; when the third size relationship indicates that the output voltage threshold is greater than or equal to the expected output voltage with the largest value, determining the expected output voltage with the largest value as the target output voltage; when the third size relationship indicates that the output voltage threshold is less than the expected output voltage with the largest value, determining the output voltage threshold as the target output voltage.

[0056] The embodiment of the present application provides a method for determining the target output voltage of the converter when multiple heating units are running simultaneously. Specifically:

[0057] First, when the system detects that multiple heating units on the wind turbine blades need to be heated, the system calculates the corresponding expected output voltage based on the target temperature of each heating unit.

[0058] Among the expected output voltages of all target heating units, the system will find the expected output voltage with the largest value. At the same time, due to the limited output capacity of the converter, the system also needs to determine an output voltage threshold, which is the maximum output voltage that the converter can provide, usually the DC bus voltage divided by the square root of 2, to ensure that the output voltage does not exceed the physical limitations of the converter.

[0059] Next, the system will compare the relationship between the maximum expected output voltage and the output voltage threshold, that is, the third magnitude relationship. If the maximum expected output voltage is less than or equal to the output voltage threshold, it means that the converter is capable of meeting the needs of all heating units; conversely, if the maximum expected output voltage is greater than the output voltage threshold, it means that the output capacity of the converter is insufficient to meet the expected voltage of a certain heating unit and needs to be adjusted.

[0060] Based on the result of the third magnitude relationship, the system determines the final target output voltage. If the maximum expected output voltage is less than or equal to the output voltage threshold, the target output voltage is set to the maximum expected output voltage, which ensures that the heating effect is maximized and within the capacity of the converter. If the maximum expected output voltage is greater than the output voltage threshold, the target output voltage is set to the output voltage threshold, i.e., the maximum output voltage of the converter, to prevent exceeding the output capacity of the converter and ensure the stability and safety of the system.

[0061] The embodiment of the present application can achieve precise control of each heating unit in a scenario where multiple heating units are working simultaneously, while taking into account the output limitation of the inverter, avoiding damage to the system or blade material due to excessive output voltage, thereby ensuring efficient and safe operation of the electric thermal deicing system.

[0062] Optionally, determining a target heating unit according to an ice coating position and an ice coating thickness on a wind turbine blade includes: determining whether the ice coating thickness is greater than an ice coating thickness threshold; and when the ice coating thickness is greater than the ice coating thickness threshold, determining that the heating unit corresponding to the ice coating position is the target heating unit.

[0063] It should be noted that the system first needs to be able to accurately detect the ice on the wind turbine blades, which can be achieved through ice monitoring sensors installed on the blades. The sensor not only needs to detect whether there is ice, but also be able to quantify the specific location and thickness of the ice.

[0064] In the embodiment of the present application, the thickness threshold may be set based on multiple factors, such as the tolerance of the blade material, the efficiency of wind power generation, energy consumption, etc. When the detected ice thickness exceeds this threshold, the system determines that de-icing is necessary.

[0065] Once it is confirmed that the ice thickness exceeds the threshold, it is necessary to determine which heating units need to be activated based on the specific location of the ice. This is achieved by matching the detected ice location with the preset heating unit location. If the ice is located in a specific area of ​​the blade, the system will activate the heating unit in the corresponding area instead of activating all heating units, thus avoiding energy waste and unnecessary heating of the blade.

[0066] After determining the target heating unit, the system will adjust the output voltage through the inverter to accurately control the power consumption and heat generation of the heating unit, ensuring that while meeting the deicing requirements, the blade temperature will not be too high, thereby protecting the blade material, extending the blade service life, and reducing energy consumption.

[0067] In order to better understand the process of executing the above-mentioned blade deicing operation, the implementation method flow of executing the above-mentioned blade deicing operation is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0068] The electrical wiring diagram of the electric heating deicing system in the related art is as follows Figure 4 As shown, each heating unit on the fan blade is powered by a power supply, and each heating unit can only be controlled by start and stop, and the heating effect cannot be smoothly controlled.

[0069] This patent proposes a variable current controlled wind turbine blade electric heating deicing system, which can smoothly control the temperature and heating amount, such as Figure 5 As shown, it includes: a power supply, a converter, distribution terminals of each heating unit, a heating unit control contactor, a heating unit, and a temperature measuring probe, wherein:

[0070] The power supply is used to output a source voltage;

[0071] The converter is used to adjust the source voltage to output a target output voltage;

[0072] The heating unit distribution terminals are used to connect the converter with the heating units;

[0073] The heating unit allocation terminals are KM1-KMn, which are used to turn on the corresponding heating unit according to the ice position and thickness measured by the ice monitoring sensor on the blade;

[0074] A heating unit is used to heat the blade, and generally a carbon fiber heating film is used and is deployed on the blade surface according to process requirements;

[0075] The temperature measuring probe can measure temperature through optical fiber and is deployed under each heating unit.

[0076] In the embodiment of the present application, the power consumption and heat generation of the heating unit can be controlled in real time by changing the output voltage of the converter. The power consumption satisfies the following formula: P = U 2 / R.

[0077] The embodiment of the present application also provides a control method for the electric heating deicing system of the wind turbine blades controlled by variable current, specifically:

[0078] First, according to the ice position and thickness measured by the ice monitoring sensor on the blade, the corresponding heating unit can be turned on, and then the inverter output voltage is adjusted to accurately control the heating unit's heat output, thereby reducing system losses while meeting deicing requirements and minimizing the impact on blade materials. If the heating temperature is too high, the blade material will age faster, affecting the blade life and unit operation safety. The inverter output voltage control strategy is as follows: Figure 6 shown.

[0079] First, the difference between the ice thickness and the expected ice thickness is input into the PI controller, and the first expected temperature Tset1 of the heating unit is output through the PI controller; the temperature threshold Tmax of the target heating unit is determined, and the first size relationship between the temperature threshold Tmax and the first expected temperature Tset1 is determined; when the first size relationship indicates that the temperature threshold Tmax is greater than or equal to the first expected temperature Tset1, the first expected temperature Tset1 is determined to be the expected temperature Tset; when the first size relationship indicates that the temperature threshold Tmax is less than the first expected temperature Tset1, the temperature threshold Tmax is determined to be the expected temperature Tset;

[0080] Secondly, the temperature difference between the expected temperature and the measured temperature T is input into the PI controller, and the expected output voltage Uset1 is output through the PI controller; the output voltage threshold Umax of the converter is determined, and the second size relationship between the output voltage threshold Umax and the expected output voltage Uset1 is determined; when the second size relationship indicates that the output voltage threshold Umax is greater than or equal to the expected output voltage Uset1, the expected output voltage is determined to be the target output voltage Uset; when the second size relationship indicates that the output voltage threshold Umax is less than the expected output voltage Uset1, the output voltage threshold Umax is determined to be the target output voltage Uset.

[0081] It should be noted that the control target of blade ice thickness is no ice, and T is the temperature measurement value of the heating unit. After obtaining the Uset reference voltage, the on and off of the switching devices in the converter can be controlled by the SVPWM space vector algorithm. The first limit is the temperature setting limit, which is mainly determined by the tolerance of the blade material. The minimum value is generally set to 0. The second limit is limited by the output capacity of the converter, and the maximum output voltage is the DC bus voltage / root 2.

[0082] Through the embodiments of the present application, precise control of the heating unit is achieved, system losses are reduced while meeting de-icing requirements, and the safe and stable operation capability and power generation of the wind turbine are improved.

[0083] 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 this understanding, the technical solution of the present application, or the part that contributes to the relevant technology, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, disk, CD), 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 described in each embodiment of the present application.

As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function.
