Description

Technical Field

[0001] The present invention relates to the technical field of power generation equipment control, and in particular to an intelligent control system and method for a wind turbine generator set based on multi-dimensional sensing. Background Art

[0002] Wind turbines are devices that convert wind energy into electrical energy. They are usually composed of wind rotors, generators, towers, etc. The wind rotors rotate under the action of wind power, and drive the generators to operate through the transmission device, thereby generating electrical energy. They are widely used in the field of wind power and are important equipment for realizing the utilization of clean energy.

This application aims to solve the problem that "for wind turbine generator sets, the main control components of in-service wind turbine generator sets have low degree of openness and low intelligence. With the increasing demand for big data and edge computing applications, the demand for complex data processing functions is gradually increasing. It is difficult for existing controllers to meet the requirements of openness, efficiency and safety at the same time."

[0004] However, the wind turbines currently in use do not have interactive functions with each other, and the yaw adjustment logic in response to wind direction is fixed and independent, resulting in weak group control capabilities of wind turbine groups and low levels of intelligence.

[0005] Therefore, an intelligent control system for wind turbines based on multi-dimensional sensing is proposed. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides an intelligent control system and method for a wind turbine generator set based on multi-dimensional sensing, which can effectively solve the problems of the prior art.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The present invention discloses an intelligent control system for a wind turbine generator set based on multi-dimensional sensing, comprising:

[0009] A differentiation module is used to upload wind turbine distribution information and differentiate wind turbines based on the wind turbine distribution information; a perception module is used to perceive wind-related information in real time and store wind-related information; a retrieval module is used to retrieve the latest wind-related information from the stored wind-related information; an analysis module is used to receive wind-related information retrieved by the retrieval module and analyze the optimal yaw angle of the wind turbine using the wind-related information; a sharing module is used to obtain the optimal yaw angle of the wind turbine analyzed in the analysis module and feed back the optimal yaw angle to other wind turbines in the differentiation interval where the source wind turbine is located in the differentiation module; a driving module is used to drive the wind turbine to adjust to the optimal yaw angle;

[0010] The system continuously operates based on a user-defined cycle at the system end to continuously control the wind turbine generator set.

[0011] Furthermore, the wind turbine generator set is not unique, and the wind turbine generator set distribution information uploaded during the operation phase of the differentiation module comes from the system end user, and the wind turbine generator set distribution information includes the land surface model of the wind turbine generator set distribution area and the location information of the wind turbine generator set in the land surface model of the wind turbine generator set distribution area;

[0012] During the operation phase of the differentiation module, the system end user synchronizes and customizes the height difference allowable threshold, and the differentiation module differentiates the wind turbine generator sets based on the height difference allowable threshold and the position information of the wind turbine generator sets in the land surface model of the generator generator set distribution area, so that the difference between the maximum value and the minimum value of the height determined based on the position coordinates of the wind turbine generator sets in the same differentiation interval is less than the height difference allowable threshold;

[0013] Among them, after distinguishing each wind turbine generator set, the distinguishing module networks the wind turbine generator sets belonging to each distinguishing interval. When there is only one wind turbine generator set in the distinguishing interval, the networking operation is not performed.

[0014] Furthermore, the wind-related information sensed by the sensing module includes: wind speed, wind direction angle, and air density. The sensing module is integrated with sensors capable of sensing wind-related information. The sensing module is arranged on each wind turbine generator set. The sensors deployed on each wind turbine generator set are not unique, and the number of sensors deployed on each wind turbine generator set is equal.

[0015] The sensors are deployed in a ring shape on the tower surface of the wind turbine generator set.

[0016] Furthermore, a storage unit is provided at the lower level of the perception module, and the storage unit is used to receive wind-related information perceived by the perception module and to distinguish and store wind-related information;

[0017] Each partitioned storage interval is named based on the location information of the wind turbine generator set to which the wind power related information stored therein belongs, so that the wind power related information stored in each partitioned storage interval all comes from the same wind turbine generator set;

[0018] Among them, after the wind turbine generator sets are divided and networked, the storage unit is networked with any wind turbine generator sets in each division interval, so that the storage unit and at least one wind turbine generator set in each wind turbine generator set division interval have data exchange conditions.

[0019] Furthermore, a storage unit is provided at the lower level of the perception module, and the storage unit is used to receive wind-related information perceived by the perception module and to distinguish and store wind-related information;

[0020] Each partitioned storage interval is named based on the location information of the wind turbine generator set to which the wind power related information stored therein belongs, so that the wind power related information stored in each partitioned storage interval all comes from the same wind turbine generator set;

[0021] Among them, after the wind turbine generator sets are divided and networked, the storage unit is networked with any wind turbine generator sets in each division interval, so that the storage unit and at least one wind turbine generator set in each wind turbine generator set division interval have data exchange conditions.

[0022] Furthermore, a screening unit is provided at the lower level of the analysis module, and the screening unit is used to traverse the wind-related information currently retrieved by the retrieval module, sort the wind-related information based on the position relationship of its source sensor on the tower surface of the wind turbine generator set, identify the highest wind speed source sensor, and use the wind-related information of the identified sensor itself and the sensors adjacent to it and of equal number on its left and right sides as analysis targets;

[0023] The wind-related information used as the analysis target is one half of the wind-related information received by the analysis module during operation.

[0024] Furthermore, when analyzing the optimal yaw angle of the wind turbine generator set in the analysis module, the following is obeyed:

[0025] The three wind speeds, wind direction angles, and air density sensed by each sensor are averaged respectively;

[0026] After the averaging operation, the corresponding sensors are denoted as v1 , α 1 , 1 ;v 2 , α 2 , 2 ;v 3 , α 3 , 3 ; ..., the parameter subscript indicates the sensor number;

[0027]

[0028] Where: P i (a i ) is the wind energy captured by the wind turbine when the yaw angle is a; ρ i is the air density; A is the swept area of ​​the wind wheel; v i is the wind speed; C p (λ,β) is the wind energy utilization coefficient;

[0029] Among them, A, C p (λ,β) is derived from the parameter P i (a i ) The subscript corresponds to the wind turbine generator set where the sensor is located. Based on the above calculation, the P i (a i ) value is maximum, P i (a i ) The subscript corresponds to the sensor to which the sensor serial number belongs. The wind direction angle in the latest wind-related information sensed by the sensor is used as the optimal yaw angle. The sensor is used as a reference target, and the optimal yaw angle is rotated toward the direction of the reference target.

[0030] Furthermore, the wind turbine generator sets in the same division interval in the division module execute the same yaw control movement.

[0031] Furthermore, the differentiation module is interactively connected to a perception module via a wireless network, the perception module is interactively connected to a storage unit via a wireless network, the perception module is interactively connected to a retrieval module and an analysis module via a wireless network, the retrieval module is interactively connected to a storage unit via a wireless network, the analysis module is interactively connected to a screening unit via a wireless network, and the analysis module is interactively connected to a sharing module and a driving module via a wireless network.

[0032] In a second aspect, a wind turbine generator intelligent control method based on multi-dimensional sensing comprises the following steps:

[0033] The wind turbine distribution information is obtained, the wind turbines are differentiated based on the wind turbine distribution information, and the wind turbines in each zone are networked so that each wind turbine in the same zone has the conditions for data exchange; based on the sensing device, the wind-related information is sensed on the surface of the wind turbine tower in real time, the wind-related information is retrieved, the wind-related information is screened, and the screened wind-related information is used to analyze the optimal yaw angle of the wind turbine; the optimal yaw angle of the wind turbine is shared with other wind turbines based on the networking result of the zone where it is located; the wind turbine is controlled to make yaw adjustments based on the optimal yaw angle to adapt to the current ambient wind.

[0034] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0035] The present invention distinguishes wind turbines with synchronous control conditions by identifying the terrain distribution of wind turbines, and further analyzes the real-time optimal yaw direction of the wind turbines based on the multi-directional perception of wind-related information, synchronously networks the wind turbines with synchronous control conditions, and adaptively distributes the optimal yaw direction, so that the wind turbines can synchronously adjust the yaw direction, improve the energy conversion efficiency of the wind turbines, and realize real-time linkage and comprehensive intelligent control of the wind turbines.

[0036] At the same time, during the analysis stage of the optimal yaw direction, the wind-related information used in the analysis process is screened, which effectively reduces the system operation processing data, and based on the screening, high-value data is obtained and applied to the analysis of the optimal yaw direction to ensure the effectiveness of the control of the optimal yaw direction of the wind turbine.

[0059] The wind-related information used as the analysis target is one-half of the wind-related information received by the analysis module during operation;

[0060] The optimal yaw angle of the wind turbine in the analysis module is subject to:

[0061] The three wind speeds, wind direction angles, and air density sensed by each sensor are averaged respectively;

[0062] After the averaging operation, the corresponding sensors are denoted as v 1 , α 1 , 1 ;v 2 , α 2 , 2 ;v 3 , α 3 , 3 ; ..., the parameter subscript indicates the sensor number;

[0063]

[0064] Where: P i (a i ) is the wind energy captured by the wind turbine when the yaw angle is a; ρ i is the air density; A is the swept area of ​​the wind wheel; v i is the wind speed; C p (λ,β) is the wind energy utilization coefficient;

[0065] Among them, A, C p (λ,β) is derived from the parameter P i (a i ) The subscript corresponds to the wind turbine generator set where the sensor is located. Based on the above calculation, the P i (a i ) value is maximum, P i (a i ) The subscript corresponds to the sensor to which the sensor number belongs, the wind direction angle in the latest wind force information sensed by the sensor is used as the optimal yaw angle, the sensor is used as the reference target, and the optimal yaw angle is rotated toward the reference target direction;

[0067] It should be noted that the wind energy utilization coefficient is a function of the tip speed ratio λ and the pitch angle β;

[0068]

[0069] Where: C 1 , C 2 , C 3 , C 4 , C 5 It is an empirical coefficient related to the design of wind turbine blades. Different wind turbines may have different values.

[0070] A sharing module is used to obtain the optimal yaw angle of the wind turbine generator set analyzed in the analysis module, and to feed back the optimal yaw angle to other wind turbine generator sets in the partitioning interval where the source wind turbine generator set is located in the partitioning module;

[0071] A driving module, used for driving the wind turbine generator set to adjust to an optimal yaw angle;

[0072] The wind turbine generator sets in the same partition interval in the partition module perform the same yaw control movement;

[0073] Among them, the system operates continuously based on a user-defined cycle on the system end to continuously control the wind turbine generator set;

[0074] The distinguishing module is interactively connected to the perception module through a wireless network, the perception module is interactively connected to the storage unit through a wireless network, the perception module is interactively connected to the retrieval module and the analysis module through a wireless network, the retrieval module is interactively connected to the storage unit through a wireless network, the analysis module is interactively connected to the screening unit through a wireless network, and the analysis module is interactively connected to the sharing module and the driving module through a wireless network.

[0075] In this embodiment, the distinguishing module is operated to upload the distribution information of the wind turbine generator sets, and the wind turbine generator sets are distinguished based on the distribution information of the wind turbine generator sets. The perception module is post-operated to perceive the wind related information in real time and store the wind related information. The storage unit synchronously receives the wind related information perceived by the perception module, distinguishes and stores the wind related information, and the retrieval module further retrieves the latest wind related information from the stored wind related information. The analysis module then receives the wind related information retrieved by the retrieval module, and uses the wind related information to analyze the optimal yaw angle of the wind turbine generator set. The screening unit synchronously traverses the current information of the retrieval module. The wind-related information retrieved before is sorted based on the position relationship of its source sensor on the tower surface of the wind turbine generator set, and the sensor with the highest wind speed source is identified. The wind-related information of the identified sensor itself and the sensors adjacent to it and of equal number on its left and right sides are used as analysis targets, and the optimal yaw angle of the wind turbine generator set analyzed in the analysis module is obtained through the sharing module, and the optimal yaw angle is fed back to other wind turbine generator sets in the differentiation interval where its source wind turbine generator set is located in the differentiation module, and finally the driving module drives the wind turbine generator set to adjust to the optimal yaw angle.
