BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 This is the architecture diagram of the offshore wind power operation monitoring system. DETAILED DESCRIPTION

[0025] In order to solve the problems in the background technology, the present invention uses the data forwarding function of each system in the offshore wind power project and the integrated fusion access technology to uniformly transmit the full data of each system in the offshore wind power project to the offshore wind power operation monitoring platform, and performs unified data management to ensure that data from different sources can be seamlessly connected to the offshore wind power operation monitoring platform, realize the effective sharing of information between main and auxiliary equipment and auxiliary facilities, avoid the occurrence of information islands, solve the problem of difficulty in implementing integrated monitoring due to information islands, improve operation and inspection efficiency, and reduce the safety risks and maintenance costs of operation and maintenance and construction.

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and implementation methods.

[0027] An implementation method of an offshore wind power operation monitoring system:

[0028] An offshore wind power operation monitoring system comprises an offshore wind power operation monitoring platform, a convergence and forwarding device located in a safety zone I, and a convergence and forwarding device located in a safety zone II.

[0029] Among them, the offshore wind power operation monitoring platform is used to receive data sent from the convergence and forwarding device located in Safety Zone I, data sent from the convergence and forwarding device located in Safety Zone II, and data sent from the remote intelligent patrol system located in Safety Zone III, so as to monitor the entire station based on all the received data.

[0030] Among them, the convergence and forwarding device located in Safety Zone I is used to build a unified data model structure and communication protocol mapping to access the data sent by the integrated automatic monitoring system of the land-based centralized control center and the integrated automatic monitoring system of the offshore substation, and send the data accessed by the convergence and forwarding device located in Safety Zone I to the offshore wind power operation monitoring platform.

[0031] Among them, the convergence and forwarding device located in the safety zone II is used to build a unified data model structure and communication protocol mapping to access the data sent by the auxiliary control and monitoring system, and send the data accessed by the convergence and forwarding device located in the safety zone II to the offshore wind power operation monitoring platform.

[0032] Among them, the unified data model structure constructed by the convergence and forwarding device facilitates unified data management of data to be connected to the offshore wind power operation monitoring platform, and the communication protocol mapping constructed by the convergence and forwarding device is used to realize data exchange and communication between systems, devices or applications using different communication protocols.

[0033] Among them, since the architecture of the offshore substation integrated automatic monitoring system and the onshore centralized control center integrated automatic monitoring system is the same, the offshore substation integrated automatic monitoring system sends data to the onshore centralized control center integrated automatic monitoring system, and the data sent by the offshore substation integrated automatic monitoring system is transmitted to the offshore wind power operation monitoring platform through the onshore centralized control center integrated automatic monitoring system and the convergence forwarding device located in Safety Zone I.

[0034] Specifically, the offshore wind power operation monitoring platform is also used to receive data sent by the wind turbine SCADA system. The data sent by the wind turbine SCADA system includes operating condition data of wind farm wind turbine equipment, equipment self-test data and operating environment data.

[0035] Specifically, the data sent by the comprehensive automatic monitoring system of the offshore substation includes the operating condition data of the primary and secondary equipment of the offshore substation, equipment self-test data and operating environment data.

[0036] Specifically, the data sent by the auxiliary control monitoring system includes data sent by the fire monitoring system, environmental monitoring system, submarine cable monitoring system, lighting monitoring system, security monitoring system, dynamic environment monitoring system, access control monitoring system and wind power prediction system.

[0037] Specifically, the offshore wind power operation monitoring platform is also used to collect image signals and early warning information from offshore wind farms and offshore booster stations. The image signals and early warning information from the offshore wind farms and offshore booster stations are uploaded by the offshore booster station integrated automatic monitoring system.

[0038] Specifically, the offshore wind power operation monitoring platform is also used to display the operating status information of the offshore wind farm.

[0039] like Figure 1 As shown in the figure, offshore wind power projects are divided into offshore and onshore areas based on their installation location. Offshore areas include offshore booster stations, while onshore areas include onshore centralized control centers. Furthermore, based on the secondary power system safety protection system, they are divided into Safety Zone I, Safety Zone II, and Safety Zone III. Each safety zone has different safety protection requirements. Therefore, offshore wind power project construction includes Safety Zone I for offshore booster stations, Safety Zone II for offshore booster stations, Safety Zone I for onshore centralized control centers, Safety Zone II for onshore centralized control centers, and Safety Zone III for onshore centralized control centers. A firewall is installed between Safety Zone I and Safety Zone II, and a forward / reverse isolation device is installed between Safety Zone II and Safety Zone III.

[0040] To address the diverse protocols and complex data access issues across offshore wind farm subsystems, the offshore wind power operation monitoring platform deploys convergence and forwarding devices in Safety Zones I and II for data forwarding and access. This platform utilizes integrated, fused access technology for multi-source, heterogeneous data across all subsystems of the offshore wind farm, uniformly accessing operational monitoring data from the integrated automatic monitoring system of the land-based centralized control center, the integrated automatic monitoring system of the offshore substation, the wind turbine SCADA system, and the auxiliary control and monitoring system. Furthermore, in Safety Zone III, it accesses relevant data from remote intelligent patrol systems, including video, ship, and meteorological data. The auxiliary control and monitoring system subsystems include wind power forecasting, wind turbine auxiliary control, dynamic environment monitoring, fire monitoring, environmental monitoring, submarine cable monitoring, lighting monitoring, security monitoring, and access control monitoring.

[0041] The convergence and forwarding device supports standard communication protocols such as DL / T 860, IEC104, and IEC101, can meet the needs of various types of data access, and adopts a standard data model structure. Through the dynamic instantiation of model data, it can realize the dynamic creation and management of real-time data libraries. By deploying convergence and forwarding devices in security zones I / II respectively, a unified data model structure and communication protocol mapping for the entire site are constructed to ensure that data from different sources can be seamlessly accessed to the offshore wind power operation monitoring platform. The offshore wind power operation monitoring platform adopts multi-protocol access technology of plug-in microservice architecture, which can automatically identify the protocol characteristics of accessed data, classify them, and complete data identification and interaction. In addition, the offshore wind power operation monitoring platform can also perform a series of processing on the accessed data before sending it to the relevant system for control. Such as Figure 1 As shown in the figure, the parts connected by double arrows can realize data interaction.

[0042] Figure 1 In the Safe Zone I of the land-based centralized control center, the onshore centralized control center's Safety Zone I is divided into the bay layer and the station control layer. Specifically, it includes measurement and control devices at the bay layer, the onshore centralized control center's integrated automatic monitoring system at the station control layer, protection devices at the bay layer, and real-time gateways at the station control layer. The measurement and control devices exchange data with the onshore centralized control center's integrated automatic monitoring system. The data forwarding function of the onshore centralized control center's integrated automatic monitoring system transmits operating data to convergence and forwarding device 1 located in Safe Zone I. Convergence and forwarding device 1 then transmits all relay protection data to the offshore wind power operation monitoring platform. The protection devices exchange data with the real-time gateway, which is used to exchange data with the dispatching system. Relying on unified data access technology, measurement data, operating status, and warning data from primary and secondary equipment at the onshore centralized control station are centrally collected and processed in a business unit-based manner, enabling visual monitoring.

[0043] Figure 1In the offshore substation safety zone I, the wind turbine SCADA system, the offshore substation integrated automatic monitoring system, the measurement and control device, the protection device, the box transformer measurement and control and the wind farm are included. The measurement and control device and the protection device use DL / T 860 communication messages and the offshore substation integrated automatic monitoring system to exchange data. Through the data forwarding function of the offshore substation integrated automatic monitoring system, the operation data of the relevant equipment can be directly or indirectly transmitted to the convergence forwarding device 1 through the integrated automatic monitoring system of the land centralized control center, and then the full information of the relay protection data is sent to the offshore wind power operation monitoring platform through the convergence forwarding device 1; the box transformer measurement and control and the wind farm interact with the wind turbine SCADA system, and the operation equipment status data of the wind farm wind turbine equipment is directly transmitted to the offshore wind power operation monitoring platform through the data forwarding function of the wind turbine SCADA system. The offshore wind power operation monitoring platform can uniformly process and display information data such as the operating conditions, equipment self-test, and operating environment of the primary and secondary equipment of the offshore substation, wind farm wind turbine equipment, and power prediction system. It can intuitively display the real-time information of various equipment in the offshore wind farm station, achieve integrated monitoring, and ensure the real-time nature of the data, avoiding the risk of data transmission across multiple intervals.

[0044] Figure 1 In the safety zone II of the land-based centralized control center, an auxiliary control and monitoring system is deployed. The auxiliary control and monitoring system is used to exchange data with the auxiliary and subsystems of the offshore and land-based stations. The data forwarding function of the auxiliary control and monitoring system is used to send the data to the offshore wind power operation monitoring platform through the convergence and forwarding device 2 located in the safety zone II.

[0045] Figure 1 In the offshore substation safety zone II, the offshore and land-based auxiliary stations and their subsystems are included. The offshore and land-based auxiliary monitoring equipment transmits the status quantities, telemetry and alarm information of various equipment such as dynamic environment monitoring, fire monitoring, submarine cable monitoring, and security monitoring to the offshore central switch or the land-based centralized control center switch through various intelligent electronic devices IED and controllers, and transmits all the information of the offshore and land-based auxiliary equipment and subsystems to the offshore wind power operation monitoring platform through the convergence forwarding device 2. The offshore wind power operation monitoring platform receives the relevant data and performs unified data processing to complete the unified monitoring and control of various auxiliary equipment. Figure 1 The dynamic environment monitoring, fire monitoring and security monitoring are all existing technologies and will not be described in detail here.

[0046] exist Figure 1 In the safety zone III of the land-based centralized control center, a remote intelligent patrol system is deployed. Through the data forwarding function of the remote intelligent patrol system server, the intelligent image recognition result information of each camera processed by artificial intelligence technology is transmitted to the offshore wind power operation monitoring platform, and the perimeter intelligent deployment, out-of-bounds warning and equipment intelligent defect recognition functions are realized according to the early warning information.

[0047] The offshore wind power operation monitoring platform exchanges data with the offshore booster station integrated automatic monitoring system, the onshore centralized control center integrated automatic monitoring system, the auxiliary control monitoring system, and the remote intelligent patrol system, enabling the transmission and aggregation of application data. The relevant interface interaction protocols adhere to industry standards. The offshore wind power operation monitoring platform enables data collection and processing, storage and synchronization, operation and control, graphics and alarms, permissions, and auditing, providing foundational functional support for various applications and offering platform services.

[0048] The offshore wind power operation monitoring platform integrates data from the onshore centralized control center's Safety Zone I, offshore substation's Safety Zone I, onshore centralized control center's Safety Zone II, offshore substation's Safety Zone II, and onshore centralized control center's Safety Zone III to complete the functional design of three business modules: panoramic operation monitoring, intelligent operation and maintenance management, and intelligent safety protection control.

[0049] Panoramic operation monitoring mainly realizes panoramic monitoring of the entire station data, including the operation status of the entire wind farm, real-time power generation, daily, monthly and annual power generation, power curve, power generation curve and other operation status information display; the entire station electrical topology wiring, interval communication, main transformer and line interval information, real-time alarms, and historical alarms of relay protection equipment are centrally displayed; dynamic perception and remote control visualization of main and auxiliary equipment.

[0050] Smart operation and maintenance management: Use equipment monitoring data to conduct health evaluation and early warning, locate equipment health status, realize intelligent diagnosis, early warning and processing of primary and secondary equipment, and customize operation and maintenance plans and management rules through management systems to complete intelligent operation and maintenance management of the entire site.

[0051] Intelligent safety protection control: mainly targets the equipment and personnel operating environment in special offshore scenarios, and realizes functions such as safety operation warning and emergency response plan, positioning monitoring of surrounding ships and personnel, and fire safety management and control.

[0052] With the large-scale construction of offshore wind power and the urgent need to improve operation and maintenance technologies, the integrated intelligent application of offshore wind power monitoring systems has become an important means to improve operational efficiency, reduce costs and ensure safety. It can support the digital commissioning and digital operation and maintenance of offshore wind power systems throughout their life cycle.
