[0001] The present invention relates to the field of wind power generation technology, and more particularly to a wind power system. Background Technology

[0002] With the gradual depletion of energy sources such as coal and oil, humanity is increasingly emphasizing the utilization of renewable energy. Wind energy, as a clean and renewable energy source, is receiving growing attention worldwide. For coastal islands, grassland pastoral areas, mountainous regions, and plateaus lacking water, fuel, and with inconvenient transportation, utilizing wind power in a way that is tailored to local conditions is highly suitable and has great potential. Wind power generation refers to using wind turbines to convert the kinetic energy of wind into electrical energy.

[0003] The control system of a wind turbine is a crucial component, undertaking important tasks such as monitoring, automatic adjustment, maximizing wind energy capture, and ensuring good grid compatibility. It mainly consists of a monitoring system, a main control system, a pitch control system, and a frequency converter system (inverter). The main control system is the core control component of the wind turbine, directly affecting its performance and safety. It needs to collect various sensor signals and operational data to monitor and protect the turbine, ensuring stable and safe power output through power and frequency regulation, and providing comprehensive turbine data support. Existing main control systems require extensive data storage and processing, thus placing significant data storage and computational demands on them. Summary of the Invention

Figure 1 As shown, the wind turbine 100 includes multiple blades 101, a nacelle 102, a hub 103, and a tower 104. The tower 104 extends upward from the foundation (not shown), the nacelle 102 is mounted on the top of the tower 104, the hub 103 is mounted on one end of the nacelle 102, and multiple blades 101 are mounted on the hub 103.

[0016] Figure 2 A general schematic block diagram of a wind power system 1 according to an embodiment of the present invention is shown. Figure 2As shown, a wind power system 1 according to an embodiment of the present invention includes a wind turbine 100, a main control system 10, a multi-monitoring system 20, and an edge computing terminal 30. The multi-monitoring system 20 can collect a first data signal D1 from the wind turbine 100. The multi-monitoring system 20 is communicatively connected to both the main control system 10 and the edge computing terminal 30. The multi-monitoring system 20 can send at least a portion of the collected first data signal D1 to both the main control system 10 and the edge computing terminal 30. The main control system 10 and the edge computing terminal 30 are bidirectionally connected, and the main control system 10 can send a second data signal D2 from the wind turbine 100 to the edge computing terminal 30. The edge computing terminal 30 can collect at least a portion of the first data signal D1 from the multi-monitoring system 20 and the second data signal D2 from the main control system 10, and store these signals. The edge computing terminal 30 can generate a control signal C based on the received at least a portion of the first data signal D1 and the second data signal D2 and return it to the main control system 10.

[0017] The edge computing terminal 30 of this embodiment of the invention can be equipped with one or more algorithm APPs (application programs). Therefore, the edge computing terminal 30 can perform corresponding data processing on at least some of the collected data signals, perform edge computing on some data signals, and perform some more complex calculations. After the calculation is completed, it can generate corresponding control signals C to the main control system 10. In this way, a portion of the computing power of the main control system 10 can be shared, and the computing pressure on the main control system 10 can be effectively reduced.

[0018] In this embodiment of the invention, the wind power system 1 is equipped with an additional edge computing terminal 30. The edge computing terminal 30 can communicate with the multi-monitoring system 20 and the main control system 10. The edge computing terminal 30 can share some of the data storage and data processing functions of the main control system 10, thereby effectively reducing the data storage pressure and computing load of the main control system 10.

[0019] The wind power system 1 has a turbine side S1 and a wind farm side S2. The main control system 10 and the multi-monitoring system 20 are located on the turbine side S1. Figure 3 Revealed Figure 2 A schematic block diagram of a specific embodiment of the wind power system 1 shown. (See diagram for example.) Figure 3 As shown, in some embodiments, edge computing functionality can be deployed on the wind turbine side S1. Therefore, the edge computing terminal 30 of this embodiment may include a first edge computing terminal 31 located on the wind turbine side S1.

[0020] The multi-monitoring system 20 can send the first part D11 of the acquired first data signal D1 to the main control system 10, and send the second part D12 of the acquired first data signal D1 to the first edge computing terminal 31. The main control system 10 can send the first part D21 of the second data signal D2 to the first edge computing terminal 31. The first edge computing terminal 31 receives the second part D12 of the first data signal D1 from the multi-monitoring system 20 and the first part D21 of the second data signal D2 from the main control system 10, and can generate a first control signal C1 based on the second part D12 of the first data signal D1 and the first part D21 of the second data signal D2 to the main control system 10, thereby sharing some of the computational burden of the main control system 10.

[0021] In some embodiments, at least a portion of the first data signal D1 sent by the multi-monitoring system 20 to the master control system 10, and at least a portion of the data signal D1 sent by the multi-monitoring system 20 to the first edge computing terminal 31, may be different.

[0022] Wind power system 1 also includes server 40 located on the wind farm side S2. (Continue to refer to...) Figure 3 As shown, the first edge computing terminal 31 in this embodiment of the invention can also establish a bidirectional communication connection with the server 40. The first edge computing terminal 31 can upload a third data signal D3 to the server 40, and the server 40 can train an algorithm model based on the third data signal D3 and then distribute the trained first algorithm model M1 to the first edge computing terminal 31. The distributed first algorithm model M1 can be mounted on the first edge computing terminal 31 in the form of an algorithm application, thereby enabling the first edge computing terminal 31 to perform one or more computational functions to support one or more corresponding business requirements.

[0023] The third data signal D3 uploaded by the first edge computing terminal 31 to the server 40 may include at least a portion of the data in the second part D12 of the first data signal D1 from the multi-monitoring system 20 and the first part D21 of the second data signal D2 from the main control system 10, and / or the data obtained by the first edge computing terminal 31 after processing the received at least a portion of the data signals.

[0024] Figure 4 Revealed Figure 2 A schematic block diagram of another specific embodiment of the wind power system 1 shown. (See diagram below.) Figure 4 As shown, in some other embodiments, edge computing functionality can be deployed on the wind farm side S2. Therefore, the edge computing terminal 30 in this embodiment of the invention may include a second edge computing terminal 32 integrated in the server 40 on the wind farm side S2.

[0025] The multi-monitoring system 20 can send the first part D11 of the acquired first data signal D1 to the main control system 10, and send the third part D13 of the acquired first data signal D1 to the second edge computing terminal 32. The main control system 10 can send the second part D22 of the second data signal D2 to the second edge computing terminal 32. The second edge computing terminal 32 receives the third part D13 of the first data signal D1 from the multi-monitoring system 20 and the second part D22 of the second data signal D2 from the main control system 10, and can generate a second control signal C2 based on the third part D13 of the first data signal D1 and the second part D22 of the second data signal D2 to the main control system 10, thereby sharing some of the computational burden of the main control system 10.

[0026] In some embodiments, at least a portion of the first data signal D11 sent by the multi-monitoring system 20 to the master control system 10 and at least a portion of the data signal D13 sent by the multi-monitoring system 20 to the second edge computing terminal 32 may be different.

[0027] Continue to refer to Figure 4 As shown, the second edge computing terminal 32 in this embodiment of the invention can also communicate bidirectionally with the cloud 50. The second edge computing terminal 32 can communicate with the cloud 50 via, for example, a network or wireless connection, such as 4G or 5G (depending on the owner's permission). The second edge computing terminal 32 can upload the fourth data signal D4 to the cloud 50. The cloud 50 can train an algorithm model based on the fourth data signal D4 and then distribute the trained second algorithm model M2 to the second edge computing terminal 32. The distributed second algorithm model M2 can be implemented on the second edge computing terminal 32 in the form of an algorithm app, allowing the second edge computing terminal 32 to perform one or more computational functions to support one or more corresponding business requirements.

[0028] The fourth data signal D4 uploaded by the second edge computing terminal 32 to the cloud 50 may include at least part of the third part D13 of the first data signal D1 from the multi-monitoring system 20 and the second part D22 of the second data signal D2 from the main control system 10, and / or the data obtained by the first edge computing terminal 31 after processing the received at least part of the data signal.

[0029] Figure 5 Revealed Figure 2 A schematic block diagram of another specific embodiment of the wind power system 1 shown. For example... Figure 5As shown, in some other embodiments, edge computing functions can be deployed simultaneously on the wind turbine side S1 and the wind farm side S2. Therefore, the edge computing terminal 30 of this embodiment can simultaneously include a first edge computing terminal 31 located on the wind turbine side S1 and a second edge computing terminal 32 located on the wind farm side S2.

[0030] The multi-monitoring system 20 can send the first part D11 of the acquired first data signal D1 to the main control system 10, the second part D12 of the acquired first data signal D1 to the first edge computing terminal 31, and the third part D13 of the acquired first data signal D1 to the second edge computing terminal 32. The main control system 10 can send the first part D21 of the second data signal D2 to the first edge computing terminal 31, and the second part D22 of the second data signal D2 to the second edge computing terminal 32.

[0031] The first edge computing terminal 31 receives a second portion D12 of a first data signal D1 from the multi-monitoring system 20 and a first portion D21 of a second data signal D2 from the main control system 10. It can generate a first control signal C1 for the main control system 10 based on the second portion D12 and the first portion D21, thereby reducing the computational burden on the main control system 10. The second edge computing terminal 32 receives a third portion D13 of a first data signal D1 from the multi-monitoring system 20 and a second portion D22 of a second data signal D2 from the main control system 10. It can generate a second control signal C2 for the main control system 10 based on the third portion D13 and the second portion D22, further reducing the computational burden on the main control system 10.

[0032] The first edge computing terminal 31, deployed on the wind turbine side S1, focuses more on timely data processing and data filtering; while the second edge computing terminal 32, deployed on the wind farm side S2, focuses more on farm-level processing and historical data management. Thus, the first edge computing terminal 31 on the wind turbine side S1 and the second edge computing terminal 32 on the wind farm side S2 can collaborate with each other. Based on the data signals acquired by the multi-monitoring system 20, edge computing is comprehensively considered, and the various applications mounted on the first edge computing terminal 31 and the second edge computing terminal 32 are hierarchically divided, and the corresponding data is also layered, thereby reducing data transmission pressure and improving processing timeliness.

[0033] In some embodiments, at least a portion of the first data signal D11 sent by the multi-monitoring system 20 to the main control system 10, the second portion D12 sent by the multi-monitoring system 20 to the first edge computing terminal 31, and the third portion D13 sent by the multi-monitoring system 20 to the second edge computing terminal 32 can all be different. In one embodiment, the first data signal D1 collected by the multi-monitoring system 20 can be divided into layers according to the time response speed of the data. For example, the first portion D11 of the first data signal D1 sent to the main control system 10 can be very urgent data that needs to be fed back to the main control system 10 in a timely manner so that the main control system 10 can respond promptly. The second portion D12 of the first data signal D1 sent to the first edge computing terminal 31 on the wind turbine side S1 is less urgent and has a slower time response speed than the first portion D11 of the first data signal D1. The third part D13 of the first data signal D1 sent to the second edge computing terminal 32 on the wind farm side S2 is less urgent and immediacy than the second part D12 of the first data signal D1. It usually contains less important data and focuses more on historical data for management.

[0034] Continue to refer to Figure 5 As shown, similarly, the first edge computing terminal 31 can upload the third data signal D3 to the server 40. The server 40 can train an algorithm model based on the third data signal D3 and then send the trained first algorithm model M1 back to the first edge computing terminal 31. The second edge computing terminal 32 can upload the fourth data signal D4 to the cloud 50. The cloud 50 can train an algorithm model based on the fourth data signal D4 and then send the trained second algorithm model M2 back to the second edge computing terminal 32.

[0035] Among them, at least some of the signals in the third data signal D3 and the fourth data signal D4 may be different, and the first algorithm model M1 and the second algorithm model M2 may be different. Therefore, the algorithm APPs mounted on the first edge computing terminal 31 and the second edge computing terminal 32 may be different.

[0036] The wind power system 1 in this embodiment of the invention may include a switch, wherein the edge computing terminal 30 can communicate with the main control system 10 and the multi-monitoring system 20 through the switch.

[0037] Figure 6 A schematic diagram of the communication connection of a wind power system 1 according to an embodiment of the present invention is shown. For example... Figure 6As shown, the switches may include ring network switches for forming the wind turbine ring network 60. The ring network switches may include a tower-based ring network switch 61 located on the wind turbine side S1 and a wind farm ring network switch 62 located on the wind farm side S2. The tower-based ring network switch 61 and the wind farm ring network switch 62 can be interconnected, for example, via optical fiber, thereby realizing the communication connection between the wind turbine side S1 and the wind farm side S2. The main control system 10 can be connected to the tower-based ring network switch 61, for example, via a communication cable, thereby connecting the main control system 10 to the wind turbine ring network 60. The server 40 can be connected to the wind farm ring network switch 62, for example, via optical fiber, thereby also connecting the server 40 to the wind turbine ring network 60.

[0038] In the case where the edge computing terminal 30 includes a first edge computing terminal 31 located on the wind turbine side S1, the first edge computing terminal 31 can be connected to the tower base ring network switch 61 via a communication cable, for example. Then the first edge computing terminal 31 can communicate with the main control system 10 and the multi-monitoring system 20 through the tower base ring network switch 61.

[0039] In the case where the edge computing terminal 30 includes a second edge computing terminal 32 integrated in the server 40 on the wind farm side S2, the second edge computing terminal 32 can communicate through the wind farm ring network switch 62.

[0040] The multi-monitoring system 20 described in this embodiment of the invention has a broad concept and may include acquisition devices for collecting various data signals from the wind turbine 100. In some embodiments, the multi-monitoring system 20 may include, for example, at least one of the following: a CMS (Condition Monitoring System) acquisition station 21, a blade acquisition station 22, a bolt monitoring system 23, and a tower yaw platform 24.

[0041] The CMS data acquisition station 21 can be connected to multiple related sensor probes to collect motion measurements of the rotating components of the main drive chain of the wind turbine 100, including data such as displacement, velocity, acceleration, and temperature. Of course, in other embodiments, the CMS data acquisition station 21 may also include other monitoring parameters, such as oil impurity monitoring. The CMS data acquisition station 21 can be located in the nacelle 102.

[0042] The CMS data acquisition station 21 can be connected to the main control system 10 via an industrial bus, thereby enabling communication between the CMS data acquisition station 21 and the main control system 10. The switch in this embodiment also includes a nacelle switch 71 located on the wind turbine side S1. The nacelle switch 71 and the tower base ring network switch 61 can be interconnected via communication cables or optical fibers. The CMS data acquisition station 21 can be connected to the nacelle switch 71 via communication cables or optical fibers. Thus, the CMS data acquisition station 21 can be indirectly connected to the tower base ring network switch 61 and ultimately connected to the wind turbine ring network 60. Furthermore, this achieves communication between the CMS data acquisition station 21 and the first edge computing terminal 31 and / or the second edge computing terminal 32.

[0043] The blade acquisition station 22 can acquire the vibration and flapping information of the blade, for example, by using a three-dimensional gyroscope and a three-dimensional angular acceleration. Furthermore, various attitude information of the blade can be derived from the information of the three-dimensional gyroscope and the three-dimensional angular acceleration.

[0044] The blade acquisition station 22 can be connected to the main control system 10 via an industrial bus, thereby enabling communication between the blade acquisition station 22 and the main control system 10. The wind power system 1 of this embodiment may also include a nacelle wireless AP (Access Point) 72 located on the wind turbine side S1. The blade acquisition station 22 can be wirelessly connected to the nacelle wireless access point 72, which can be connected to the nacelle switch 71 via a communication cable, for example. Since the nacelle switch 71 is interconnected with the tower base ring network switch 61, the blade acquisition station 22 can be indirectly connected to the tower base ring network switch 61, and ultimately connected to the wind turbine ring network 60. This achieves communication between the blade acquisition station 22 and the first edge computing terminal 31 and / or the second edge computing terminal 32.

[0045] The bolt monitoring system 23 can be used to monitor the deformation or fracture information of some critical bolts. It can use displacement sensors, ultrasonic devices, or image recognition devices to collect bolt deformation or fracture information. Critical bolts may include, but are not limited to, tower base bolts and hub blade root connection bolts.

[0046] The bolt monitoring system 23 can be connected to the main control system 10 via an industrial bus, thereby enabling communication between the bolt monitoring system 23 and the main control system 10. The wind power system 1 of this embodiment may also include a tower base gateway 73 located on the wind turbine side S1. The bolt monitoring system 23 can be connected to the tower base gateway 73 via a communication cable, and the tower base gateway 73 can be connected to the tower base ring network switch 61 via a communication cable. Thus, the bolt monitoring system 23 can be indirectly connected to the tower base ring network switch 61, and ultimately connected to the wind turbine ring network 60. Furthermore, this achieves communication between the bolt monitoring system 23 and the first edge computing terminal 31 and / or the second edge computing terminal 32.

[0047] The tower yaw platform 24 can be used to monitor tower sway information. For example, it can be collected using a three-dimensional gyroscope and a three-dimensional angular acceleration. Then, various attitude information of the tower can be derived from the information of the three-dimensional gyroscope and the three-dimensional angular acceleration.

[0048] The tower yaw platform 24 can be connected to the main control system 10 via an industrial bus, for example, to achieve communication between the tower yaw platform 24 and the main control system 10. The tower yaw platform 24 can also be connected to the tower base gateway 73 via a communication cable. Since the tower base gateway 73 is connected to the tower base ring network switch 61, the tower yaw platform 24 can be indirectly connected to the tower base ring network switch 61, and ultimately connected to the wind turbine ring network 60. This, in turn, achieves communication between the tower yaw platform 24 and the first edge computing terminal 31 and / or the second edge computing terminal 32.

[0049] In one or more embodiments of the present invention, the wind power system 1 is provided with an additional edge computing terminal 30, which shares some of the data storage and data processing functions of the main control system 10, thereby reducing the data storage pressure and computing load of the main control system 10.
