Description

Technical Field

[0001] This invention belongs to the field of offshore wind power technology, specifically relating to a linear topology structure for a 5MW wind turbine generator control device. Background Technology

[0002] As a core component of wind power generation systems, the performance and reliability of the control equipment for wind turbine generators are crucial to the overall operational efficiency and safety of the system. Traditional wind turbine generator control equipment typically employs a centralized control architecture, where all control components and modules are housed in a single control cabinet and connected via complex cabling. While this architecture is simple in structure, it suffers from several drawbacks, such as complex wiring, difficult maintenance, and poor scalability. Especially in large wind turbine generators, the sheer number and complexity of control devices make the traditional centralized control architecture insufficient to meet practical needs.

[0003] In recent years, various new control equipment architectures for wind turbine generators have emerged, among which the linear topology has attracted widespread attention due to its advantages such as simple structure, ease of expansion, and convenient maintenance. The linear topology divides control equipment according to function and connects them via communication methods such as buses or fiber optics, forming a linear structure. This structure can greatly improve the reliability and maintainability of control equipment, while reducing wiring complexity and facilitating system expansion and upgrades. However, the linear topology of current wind turbine generator control equipment still has some shortcomings, such as slow communication speed, unstable data transmission, and poor compatibility of expansion modules. Summary of the Invention

[0025] This invention designs a linear topology for the control equipment of a 5MW wind turbine generator set, used in the wind turbine generator set control system. Starting from a PLC (Programmable Logic Controller), various modules are connected via an E-bus on the backplane to achieve rapid data transmission and accurate command execution. Simultaneously, the system also connects the tower base and nacelle via optical fiber to ensure the stability and reliability of data transmission.

[0026] like Figure 1 As shown, a linear topology for a 5MW wind turbine generator control system includes: a tower-based debugging PLC, a tower-based switch, a tower-based human-machine interface (HMI), a first power supply, a main controller, a power grid measurement module, a first input / output module, and a first fieldbus communication module, all located at the tower base; and a nacelle-based debugging PLC, a nacelle switch, a nacelle HMI, a second power supply, a second input / output module, and a second fieldbus communication module, all located at the nacelle. The tower-based debugging PLC is connected to both the tower-based switch and the main controller. The tower-based switch is connected to the tower-based HMI and, via fiber optic cable from the tower, to the nacelle switch. The nacelle switch is connected to both the nacelle debugging PLC and the nacelle HMI. The power grid measurement module, the first input / output module, and the first fieldbus communication module are all connected to the main controller. The second input / output module and the second fieldbus communication module are connected to the nacelle switch. The main controller receives information from various sensors, actuators, and operator inputs, and manages the operation of the entire system according to predetermined control logic.

[0027] The linear topology of the 5MW wind turbine generator control equipment provided in this solution enables real-time monitoring, data acquisition, signal processing, and control command transmission of the wind turbine generator through multiple key components distributed in the tower base and nacelle, ensuring efficient and stable control of the wind turbine generator.

[0028] In one specific embodiment, the tower-based commissioning PLC is located at the tower base and is mainly used for commissioning and communication. It is connected to the main controller via an E-bus on the backplane for commissioning and communication. The tower-based switch connects the tower-based HMI and the nacelle switch, providing data exchange between the HMI and the main controller and nacelle equipment. It connects to the nacelle switch via fiber optic cable from the tower, enabling data transmission between the tower base and the nacelle. The tower-based HMI provides operators with an intuitive interface for monitoring and controlling the equipment at the tower base. The primary power supply provides power to the equipment at the tower base. The main controller is the core of the wind turbine generator control system, responsible for the control logic and data processing of the entire system. The main controller connects to the power grid measurement module, the first input / output module, and the first fieldbus communication module to ensure data accuracy and real-time performance. The power grid measurement module monitors the power grid status, such as voltage, current, and frequency. The first input / output module receives and sends control signals to ensure coordinated operation of all parts of the system. The first fieldbus communication module communicates with field devices, ensuring efficient data transmission between them. The nacelle commissioning PLC, located in the nacelle, is primarily used for commissioning and communication. It connects to the nacelle switch via an E-bus on the backplane. The nacelle switch connects the commissioning PLC and the nacelle HMI (Human-Machine Interface), facilitating data exchange between the HMI and various control components within the nacelle. It also connects to the tower-based switch via fiber optic cable from the tower, enabling data transmission between the nacelle and the tower. The nacelle HMI provides operators with a user interface for monitoring and controlling the equipment within the nacelle. A secondary power supply provides power to the equipment in the nacelle. A secondary input / output module receives and sends control signals from within the nacelle, ensuring coordinated operation of all components. A secondary fieldbus communication module communicates with field devices within the nacelle, ensuring efficient data transmission within the nacelle.

[0029] The power grid measurement module, first and second input / output modules, and first and second fieldbus communication modules are responsible for real-time data acquisition and monitoring, ensuring data accuracy and timeliness. Data is efficiently transmitted through switches at the tower base and nacelle, as well as fiber optic cables within the tower. The main controller determines the operating status of the wind turbine generator based on real-time data and sends control commands through the input / output modules to ensure stable system operation. The human-machine interfaces at the tower base and nacelle provide operators with an intuitive interface for convenient monitoring and control of the wind turbine generator. The first and second power supplies provide power support to the equipment at the tower base and nacelle, ensuring normal equipment operation.

[0030] In one optional embodiment, the tower-based debugging PLC is connected to the main controller via an E-bus on the backplane for debugging and communication; the tower-based switch is connected to the tower-based HMI for providing data exchange between the HMI and the main controller.

[0031] In one optional embodiment, the tower base switch is connected to the nacelle switch via tower fiber optic cable to achieve data transmission between the tower base and the nacelle; wherein coupling modules EK1521 and EK1501 are used as the interface for fiber optic connection. The nacelle commissioning PLC is connected to the nacelle switch via E-bus on the backplane for commissioning and communication; the nacelle switch is connected to the nacelle human-machine interface (HMI) to provide data exchange between the HMI and various control components inside the nacelle.

[0032] In a preferred embodiment, the system further includes an expansion module EK1110 located in the low-voltage cabinet of the engine room. The expansion module EK1110 is connected to the engine room switch via an interface and to a coupling module EK1100 located in the high-voltage cabinet of the engine room via internal cables or optical fibers. The coupling module EK1100, located in the high-voltage cabinet, is used to transmit data from the expansion module EK1110 to other devices or systems within the high-voltage cabinet.

[0033] As a specific example of this solution, the expansion module EK1110 is located in the low-voltage cabinet of the nacelle, while the coupling module EK1100 is located in the high-voltage cabinet of the nacelle. The EK1100 module is primarily responsible for transmitting data from the expansion module EK1110 to other devices or systems within the high-voltage cabinet, acting as a bridge for data exchange. Specifically, the EK1100 module connects to the expansion module EK1110 via internal cables or optical fibers to achieve data transmission between the two. Inside the nacelle, data is first pre-processed by the expansion module EK1110 and then transmitted to the entire wind turbine control system via a connection to the nacelle switch. For data that needs to be transmitted to the high-voltage cabinet, the EK1110 transmits the data to the coupling module EK1100 via internal cables or optical fibers. The EK1100 then further transmits the data to other devices within the high-voltage cabinet.

[0034] In a preferred embodiment, a terminal module EL9011 is also included, which is connected to the coupling module EK1100 via an internal cable or optical fiber.

[0035] As a specific example of this solution, the EL9011 module receives signal input from the outside and transmits it to the coupling module EK1100 via internal cables or optical fibers. The EK1100 then transmits the signal to other parts of the system, such as the main controller and the power grid measurement module.
