Abstract
Description
Technical Field
[0001] This application relates to the field of power supply device technology, and in particular to a novel power supply device for monitoring and operating high-voltage equipment of offshore wind turbines. Background Technology
[0002] With the development of offshore wind power, the number of offshore wind turbines is also increasing. During the maintenance of high-voltage transmission and transformation equipment in the event of a site-wide or single-unit power outage, the wind turbines will lack a reliable mains power supply, making it impossible to monitor the operating status of the high-voltage equipment.
[0003] Currently, wind turbine units rely solely on the main control UPS to provide secondary power to high-voltage equipment. However, the main control UPS has a large number of loads and is heavily loaded. In the event of a mains power failure, the UPS battery will quickly run out of power, making it impossible to safely and reliably remotely monitor and operate the high-voltage equipment of the wind turbine unit.
[0004] When power was restored to the entire site, since all the wind turbines were out of power, the only way to restore power to the high-voltage equipment was for maintenance personnel to board each turbine one by one. This restoration method took a long time and posed a risk to personnel safety. Utility Model Content
[0005] In view of the above problems, this application provides a new type of monitoring and operation power supply device for offshore wind turbine high-voltage equipment to solve the problem that when restoring power, since all wind turbines are de-energized, the high-voltage equipment can only be restored by maintenance personnel climbing onto each turbine one by one. This restoration method is time-consuming and poses a threat to personnel safety.
[0006] This application provides a novel monitoring and operation power supply device for offshore wind turbine high-voltage equipment, including a support platform: several sets of wind turbine high-voltage equipment are fixedly connected to the top of the support platform, offshore wind turbine towers are integrated on the wind turbine high-voltage equipment, several flexible solar panels are fixedly connected to the offshore wind turbine towers, high-voltage transmission equipment is provided on the support platform, and an energy storage mechanism is provided on one side of the wind turbine high-voltage equipment.
[0007] In some embodiments, the energy storage mechanism includes an off-grid and grid-connected energy storage inverter and a battery pack, which are mounted on a support platform and are electrically connected to the off-grid and grid-connected energy storage inverter, the battery pack, the high-voltage equipment of the wind turbine, the high-voltage transmission equipment, and the flexible solar panel.
[0008] In some embodiments, several of the flexible solar panels are equidistantly distributed on the offshore wind turbine tower.
[0009] In some embodiments, several of the battery packs are arranged at equal intervals on the support platform.
[0010] In some embodiments, several groups of the high-voltage equipment of the wind turbine are arranged at equal intervals on the support platform.
[0011] The above description is merely an overview of the technical solutions of the embodiments of this application. In order to better understand the technical means of the embodiments of this application and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of this application more obvious and understandable, specific implementation methods of this application are described below.
[0012] 1. By incorporating flexible solar panels, on-grid and off-grid energy storage inverters, and battery banks, this system can provide long-term power supply to critical loads such as wind turbine high-voltage equipment for remote monitoring, operation, and communication when there is a large-scale power outage or a single unit power outage that requires extended maintenance of high-voltage transmission equipment. When power is restored to all high-voltage equipment, operators can remotely control the equipment to quickly restore power, avoiding the need for maintenance personnel to board each unit for operation. This also significantly saves time and labor costs, and provides greater safety for maintenance personnel. Attached Figure Description

For example, "connection" or "linkage" in mechanical structures can refer to a physical connection, such as a fixed connection, a detachable connection, or an integral connection. In addition to referring to a physical connection, "connection" or "linkage" in circuit structures can also refer to an electrical connection or a signal connection. For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate component, as long as the circuit is connected. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0022] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0023] This application provides a novel monitoring and operation power supply device for offshore wind turbine high-voltage equipment, including a support platform 1: several sets of wind turbine high-voltage equipment 2 are fixedly connected to the top of the support platform 1, offshore wind turbine tower 3 is integrated on the wind turbine high-voltage equipment 2, several flexible solar panels 4 are fixedly connected to the offshore wind turbine tower 3, high-voltage transmission equipment 5 is provided on the support platform 1, and an energy storage mechanism is provided on one side of the wind turbine high-voltage equipment 2.
[0024] In the technical solution of this application embodiment, when the entire site or a single unit experiences a power outage for maintenance of the high-voltage transmission equipment 5, the mains-side switch of the off-grid energy storage inverter 6 automatically trips due to voltage loss, and uses the flexible solar panel 4 and battery pack 7 to supply power to important loads such as remote monitoring, operation, and communication of the wind turbine high-voltage equipment 2. The energy storage mechanism includes the off-grid energy storage inverter 6 and the battery pack 7, which are mounted on the support platform 1, and are electrically connected to the off-grid energy storage inverter 6, the battery pack 7, the wind turbine high-voltage equipment 2, the high-voltage transmission equipment 5, and the flexible solar panel 4.
[0025] In the technical solution of this application embodiment, the equipment is arranged at equal intervals to facilitate maintenance and operation. Several flexible solar panels 4 are distributed at equal intervals on the offshore wind turbine tower 3, several battery packs 7 are arranged at equal intervals on the support platform 1, and several sets of wind turbine high-voltage equipment 2 are arranged at equal intervals on the support platform 1.
[0026] Working principle: Flexible solar panels 4 are installed on the south-facing exterior of the offshore wind turbine tower 3. An off-grid connected energy storage inverter 6 provides uninterrupted power to critical loads such as the wind turbine's high-voltage equipment 2 for remote monitoring, operation, and communication. The inverter also charges the battery bank 7. Excess power is fed into the wind turbine's mains power grid. When there is a site-wide power outage or a single turbine failure requiring maintenance of the high-voltage transmission equipment 5, the off-grid connected energy storage inverter 6 automatically trips its mains power switch, and then uses the flexible solar panels 4 and battery bank 7 to supply power to the wind turbine's high-voltage equipment 2 for remote monitoring, operation, and communication.

Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
