Description

Technical Field

[0001] This invention relates to the field of floating wind turbine mooring systems, and more particularly to offshore floating wind turbine mooring systems. Background Technology

[0002] Offshore floating wind turbine mooring systems are structures that connect the floating foundation to the seabed. Their main function is to provide restoring force to the external environmental loads such as wind, waves, and currents borne by the floating platform through deformation or suspended weight, thereby maintaining a stable power output from the wind turbine. In order to ensure its normal operation, monitoring and management measures are usually set up to detect and solve problems in a timely manner.

[0003] A search revealed Chinese patent application CN202310951328.0, which discloses a mooring system for a floating offshore wind power platform, comprising a static mooring system and a dynamic mooring system. The static mooring system includes three mooring cable bundles, with the columns and mooring cable bundles aligned at their centers. The dynamic mooring system includes a power unit, a thruster unit, and a control unit. The power unit includes a prime mover, a generator set, a switchboard, and cables. The thruster unit includes a support shaft, a propeller, a rotating motor, and a universal joint. The control unit includes a positioning system, sensors, a computer system, a control interface, a control strategy module, and a power management module. A set of thruster units is installed below the platform's columns, with each set consisting of 1-4 thruster units. The platform monitoring system monitors the platform in real time, acquiring the platform's real-time motion level and mooring tension. Based on the platform's tilt and mooring tension requirements under real-time motion conditions, the system calculates the power required by the thruster units, which is then executed by the thruster units. The mooring system in the aforementioned patent has the following shortcomings: limited monitoring capabilities; when a single component or other component malfunctions, monitoring may be interrupted or alarms may not be triggered in a timely manner; and the fault tolerance of the monitoring is also insufficient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a floating offshore wind turbine mooring system.

[0035] S22: Each floating wind turbine subsystem alarm module determines whether the verification result meets the alarm requirements. If not, proceed to step S21; if yes, proceed to step S23.

[0036] S23: The alarm module generates alarm information;

[0037] S24: The signal transmission module transmits alarm information to the central management module and other floating wind turbine subsystems;

[0038] S25: The signal transmission module of other floating wind turbine subsystems determines whether an alarm message has been received. If it has been received, proceed to step S27; otherwise, proceed to step S26.

[0039] S26: If other floating wind turbine subsystems determine that the alarm information was not sent successfully, the next floating wind turbine subsystem will send the alarm information according to the coding order, and proceed to step S23.

[0052] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0053] Example 1:

[0054] The offshore floating wind turbine mooring system comprises multiple floating wind turbine subsystems, each of which includes:

[0055] The information acquisition module uses hardware detection devices such as sensors and detection instruments to detect the working status of the floating wind turbine and to detect parameters such as wind direction and wind force.

[0056] The information analysis module stores benchmark template information and is used to compare the information collected by the information acquisition module with the benchmark template information and generate comparison results.

[0057] The signal transmission module of each floating wind turbine subsystem enables information exchange based on wireless communication;

[0058] The remote positioning module stores a location template and receives satellite positioning data in real time. Each floating wind turbine subsystem compares the positioning data from the remote positioning module with the location template to achieve positioning calibration.

[0059] The operation verification module verifies the information transmitted by each signal transmission module to determine whether the operating status of each floating wind turbine is normal.

[0060] Specifically, the offshore floating wind turbine mooring system also includes:

[0061] The central management module and the signal transmission module interact with each other via wireless communication.

[0062] The visualization module displays the working status of each floating wind turbine subsystem on a screen.

[0068] S1: The information acquisition module uses hardware detection devices such as sensors and detection instruments to detect the working status of the floating wind turbine and to detect parameters such as wind direction and wind force;

[0069] S2: The information analysis module compares the information collected by the information acquisition module with the baseline template information and generates the comparison results;

[0070] S3: The signal transmission module broadcasts the information detected by the information acquisition module and the comparison results generated by the information analysis module to the nearby floating wind turbine subsystem;

[0076] For example:

[0077] There are floating wind turbine subsystems A, B, ..., N. Each floating wind turbine subsystem has an information acquisition module that collects information. The floating wind turbines in each subsystem have the same specifications and are located in similar areas. Assuming that floating wind turbine subsystem N / 2 is located in the middle, the other floating wind turbine subsystems use the collected information such as wind force and wind direction to simulate and determine the expected speed and other parameters of floating wind turbine subsystem N / 2.

[0078] The information analysis module of floating wind turbine subsystem N / 2 analyzes the information collected by its information acquisition module and broadcasts it to other floating wind turbine subsystems through the signal transmission module. The operation verification module of each floating wind turbine subsystem compares the received information with the pre-derived expected speed and other parameters.

[0083] S14: Use the positioning data with the highest overlap as a benchmark to correct the positioning data of other floating wind turbine subsystems.

[0084] For example, there are floating wind turbine subsystems A, B, ..., N. If only the positioning data of floating wind turbine subsystem B cannot coincide with the template, then the positioning data of floating wind turbine subsystem B is corrected.

[0085] The alarm method for the floating wind turbine subsystem includes the following steps:

[0086] S21: The work verification module generates verification results;

[0087] S22: Each floating wind turbine subsystem alarm module determines whether the verification result meets the alarm requirements. If not, proceed to step S21; if yes, proceed to step S23.

[0088] S23: The alarm module generates alarm information;

[0089] S24: The signal transmission module transmits alarm information to the central management module and other floating wind turbine subsystems;

[0090] S25: The signal transmission module of other floating wind turbine subsystems determines whether an alarm message has been received. If it has been received, proceed to step S27; otherwise, proceed to step S26.

[0091] S26: If other floating wind turbine subsystems determine that the alarm information was not sent successfully, the next floating wind turbine subsystem will send the alarm information according to the coding order, and proceed to step S23.
