Description

Technical Field

[0001] The present disclosure relates to the field of wind power generation, and more specifically, to a control method for an offshore wind power system and an offshore wind power system. Background Art

[0002] With the increasing demand for clean energy, offshore wind power systems have been developed and applied. At present, the backup power solution for offshore units mostly uses diesel generators as a backup power solution, and the main function of diesel generators is to start the diesel generators to provide power for the yaw of the unit during typhoons and off-grid periods. However, on the one hand, during the construction phase of offshore wind turbines, diesel generators may not be able to start normally; on the other hand, the long-term operation of diesel generators may lead to insufficient oil, resulting in the offshore wind turbines being unable to meet the typhoon resistance requirements under typhoon and off-grid conditions.

[0038] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0039] Figure 1 is a flowchart illustrating a control method of an offshore wind power system according to an embodiment of the present disclosure.

[0040] Reference Figure 1 In step S110, at least one of a remote input / output (I / O) module, a typhoon resistance controller, a Beidou communication system and an anemometer in the offshore wind power system is powered by a battery.

[0041] According to the embodiment of the present disclosure, the unit controller is used to control the wind turbine generator set, the anti-typhoon controller is used to control the anti-typhoon operation of the offshore wind power system, the Beidou communication system is used to transmit and exchange data between the Beidou satellite terminal and the land centralized control center, and the anemometer is used to detect the current wind speed in real time. Therefore, when the offshore wind power system encounters a typhoon, the battery can be used to power at least one of the remote input / output module, the anti-typhoon controller, the Beidou communication system and the anemometer in the offshore wind power system to cope with the impact of the typhoon.

[0042] In one embodiment, step S110 may specifically include: powering the remote input / output module of the wind turbine generator set of the offshore wind power system through the battery of the wind turbine generator set of the offshore wind power system, and powering at least one of the typhoon resistance controller, Beidou communication system and anemometer of the offshore wind power system through the battery of the diesel generator of the offshore wind power system.

[0043] According to an embodiment of the present disclosure, the diesel generator set of the offshore wind power system can provide the main power supply for the wind turbine generator set when the power grid is down or there is no electricity. The battery of the wind turbine generator set of the offshore wind power system can be called a continuous uninterrupted backup battery pack, which can continuously provide 24V control power to the system when the diesel generator is not working. The battery of the diesel generator of the offshore wind power system can be used to power at least one of the anti-typhoon controller, Beidou communication system and anemometer of the offshore wind power system when the power grid is down or there is no electricity. Therefore, in an embodiment of the present disclosure, the battery of the wind turbine generator set and the battery of the diesel generator are used to power different components respectively, instead of using a single battery to power all components, which can maximize the working time of each component and improve the overall power supply efficiency.

[0044] In step S120, one of a Supervisory Control and Data Acquisition (SCADA) system, a BeiDou terminal, and anemometer is selected based on availability of communication links of the SCADA system and the BeiDou communication system with the remote input / output module.

[0045] According to the embodiment of the present disclosure, SCADA is a computer-based automated monitoring system that can monitor and control the operating equipment on site and has been widely used in wind power generation systems to achieve various functions such as data collection, equipment control, measurement, parameter adjustment, and various signal alarms for wind power generation systems. When encountering a typhoon, the control method of the offshore wind power system according to the embodiment of the present disclosure can first check the availability of the communication link between the SCADA system and the Beidou communication system and the remote input / output module before performing the anti-typhoon operation, so that when one of the communication link between the SCADA system and the remote input / output module and the communication link between the Beidou communication system and the remote input / output module is unavailable, communication is not performed through the corresponding communication link, thereby improving the communication efficiency of the anti-typhoon operation and avoiding unnecessary time loss.

[0046] In step S130, an anti-typhoon strategy is executed based on a selected one of the SCADA system, the Beidou terminal, and the anemometer.

[0047] Based on this, when the communication link between the SCADA system and the remote input / output module is available, or when the communication link between the SCADA system and the remote input / output module is unavailable and the communication link between the Beidou communication system and the remote input / output module is available, or when the communication link between the SCADA system and the remote input / output module is unavailable and the communication link between the Beidou communication system and the remote input / output module is also unavailable, one of the SCADA system, the Beidou terminal and the anemometer can be selected, and the anti-typhoon strategy can be executed based on the selected one of the SCADA system, the Beidou terminal and the anemometer. The control method of the offshore wind power system according to an embodiment of the present disclosure can select one of the SCADA system, the Beidou terminal and the anemometer based on the availability of the communication link between the SCADA system and the Beidou communication system and the remote input / output module, and execute the anti-typhoon strategy based on the selected one of the SCADA system, the Beidou terminal and the anemometer, so that the anti-typhoon operation can be reliably performed.

[0048] In the following, we will refer to Figure 2 and Figure 3 A control method for an offshore wind power system is described when the offshore wind power system is in a construction phase and an operation phase.

[0049] Figure 2 is a flowchart illustrating a control method of an offshore wind power system when the offshore wind power system is in a construction phase according to an embodiment of the present disclosure.

[0050] Reference Figure 2 , when the offshore wind power system is in the construction stage, Figure 1 Step S110 in may correspond to Figure 2In step S210, when no typhoon warning is received, at least one of a remote input / output module, a typhoon resistance controller, a Beidou communication system and an anemometer in the offshore wind power system is powered by a storage battery.

[0051] According to an embodiment of the present disclosure, an offshore wind power system being in the construction stage may mean that the offshore wind power system is in the hoisting stage. At this time, the entire offshore wind power system is off-grid, and power transmission via the collector submarine cable and communication via the land control center and / or SCADA have not yet been enabled. Therefore, according to an embodiment of the present disclosure, when it is in the typhoon season, because the offshore wind power system may frequently encounter typhoons, the offshore wind power system may perform anti-typhoon operations when receiving a typhoon warning, or may power at least one of the remote input / output module, anti-typhoon controller, Beidou communication system and anemometer in the offshore wind power system through a battery when no typhoon warning is received, thereby preparing for the arrival of the typhoon.

[0052] When the offshore wind power system is under construction, Figure 1 Step S120 in may correspond to Figure 2 In step S220, one of the Beidou terminal and the anemometer is selected based only on the availability of the communication link between the Beidou communication system and the remote input / output module.

[0053] As mentioned above, the construction phase of the offshore wind power system may mean that the power transmission via the collection submarine cable and the communication via the land control center and / or SCADA are not yet enabled. Figure 2 In the case of an offshore wind power system under construction, it is not necessary to determine whether Figure 1 The availability of the communication link between the SCADA system and the remote input / output module in step S120 is not determined, but only the availability of the communication link between the Beidou communication system and the remote input / output module is determined; since the SCADA system needs to cooperate with the remote input / output module to operate, during the offshore wind power system construction phase when the SCADA system and / or the remote input / output module are not available, it is not necessary to select the SCADA system, but only one of the Beidou terminal and the anemometer is selected, thereby improving operational efficiency.

[0054] When the offshore wind power system is under construction, Figure 1 Step S130 in may correspond to Figure 2 In step S230, the anti-typhoon strategy is executed by communicating with the anti-typhoon controller based on a selected one of the Beidou terminal and the anemometer.

[0055] Based on this, when the offshore wind power system is in the construction stage, when the communication link between the Beidou communication system and the remote input / output module is available, or when the communication link between the Beidou communication system and the remote input / output module is unavailable, one of the Beidou terminal and the anemometer can be selected, and the anti-typhoon strategy is executed based on the selected one of the Beidou terminal and the anemometer. The control method of the offshore wind power system according to an embodiment of the present disclosure can select one of the Beidou terminal and the anemometer based on the availability of the communication link between the Beidou communication system and the remote input / output module, and execute the anti-typhoon strategy based on the selected one of the Beidou terminal and the anemometer, so that the anti-typhoon capability of the offshore wind power system during the construction stage can be achieved.

[0056] Figure 3 is a flowchart illustrating a control method of an offshore wind power system when the offshore wind power system is in an operation stage according to an embodiment of the present disclosure.

[0057] According to the embodiments of the present disclosure, compared with the construction stage of the offshore wind power system, the offshore wind power system is in the operation stage, which means that the offshore wind power system has been completed and can smoothly perform power generation tasks. At this time, under normal circumstances, the entire offshore wind power system has completed the access to the power grid, and the power transmission via the collection submarine cable and the communication via the land control center and / or SCADA have been installed. Therefore, referring to Figure 3 , when the offshore wind power system is in operation, Figure 1 Step S110 in may correspond to Figure 3 The combination of step S310 and step S320 in .

[0058] In step S310, when a typhoon warning is received, it is determined whether the power grid is powered off.

[0059] According to an embodiment of the present disclosure, since typhoons are frequently encountered during the typhoon season, both the offshore wind power system end and the land end of the power grid may be affected by previous typhoons or other factors and experience power outages. Therefore, it is possible to first determine whether the power grid is powered off before performing other operations, so as to more effectively deal with typhoons. For example, when the power grid is not powered off, power can be directly transmitted to various components or modules of the offshore wind power system through the power grid; when the power grid is powered off, step S320 can be executed.

[0060] In step S320, in response to determining that the power grid has lost power, it is checked whether the communication link between the SCADA system and the Beidou communication system and the remote input / output module is available, and at least one of the remote input / output module, the typhoon resistance controller, the Beidou communication system and the anemometer in the offshore wind power system is powered by a battery.

[0061] According to the embodiment of the present disclosure, since typhoons are frequently encountered during the typhoon season, both the SCADA system and the Beidou communication system may be affected by previous typhoons or other factors and fail. Therefore, when the offshore wind power system is in the operation stage, when a typhoon occurs, the control method of the offshore wind power system according to the embodiment of the present disclosure can first check the availability of the communication link between the SCADA system and the Beidou communication system and the remote input / output module before performing the anti-typhoon operation, so that when one of the communication link between the SCADA system and the remote input / output module and the communication link between the Beidou communication system and the remote input / output module is unavailable, communication is not performed through the corresponding communication link, thereby improving the communication efficiency of the anti-typhoon operation and avoiding unnecessary time loss.

[0062] In one embodiment, in response to determining that the power grid is powered off, it can also be determined whether the diesel generator is working. For example, in response to determining that the diesel generator is working, the diesel generator can be used to charge the battery of the wind turbine generator set of the offshore wind power system and the battery of the diesel generator. Therefore, the battery of the wind turbine generator set and the battery of the diesel generator can remain charged, thereby better supporting anti-typhoon operations. In addition, in the case where the offshore wind power system also includes a photovoltaic power generation system, in response to determining that the diesel generator is not working, the photovoltaic power generation system can be cut in, and the photovoltaic power generation system can be used to charge the battery of the wind turbine generator set of the offshore wind power system and the battery of the diesel generator of the offshore wind power system, and in response to determining that the power grid is not powered off or determining that the diesel generator is working, the photovoltaic power generation system is cut out. Therefore, when the offshore generator set is off-grid for a long time, the off-grid standby time of the diesel generator can be extended and the diesel reserve of the diesel generator can be reduced.

[0063] When the offshore wind power system is in operation, Figure 1 Step S120 in may correspond to Figure 3 The combination of step S330 and step S340 in .

[0064] In step S330, when the communication link between the SCADA system and the remote input / output module is available, the SCADA system is selected to communicate with the anti-typhoon controller. That is, in this case, the SCADA system can be selected to wake up the wind turbine controller to achieve anti-typhoon operation.

[0065] For example, when the communication link between the SCADA system and the remote input / output module is available, the anti-typhoon command provided by the anti-typhoon controller can be transmitted to the remote input / output (I / O) module of the unit control system through the ring network switch of the unit control system through the SCADA system serving as the central control, and the remote I / O module controls the closure of the relay of the wind turbine controller, and the 24V battery of the wind turbine generator set provides the wind turbine controller with an input 24V direct current (DC) power supply to wake up the wind turbine controller, and the wind turbine controller starts the diesel engine and controls the closing of the circuit breaker of the diesel engine, so that the anti-typhoon command provided by the anti-typhoon controller can finally realize the anti-typhoon operation of the wind turbine through the SCADA system and the wind turbine controller.

[0066] In step S340, when the communication link between the SCADA system and the remote input / output module is unavailable, only one of the Beidou terminal and the anemometer is selected to communicate with the anti-typhoon controller based on the availability of the Beidou communication system.

[0067] According to an embodiment of the present disclosure, Figure 3 Step S340 in Figure 2 That is, Figure 3 The operation of step S340 in "selecting one of the Beidou terminal and the anemometer based only on the availability of the Beidou communication system" can be combined with Figure 2 In one embodiment, Figure 3 The operation of step S340 in “selecting one of the Beidou terminal and the anemometer based only on the availability of the Beidou communication system” and Figure 2 Step S220 in may include step S341 (not shown) and step S342 (not shown).

[0068] In step S341, when the communication link between the Beidou communication system and the remote input / output module is available, the Beidou terminal is selected. That is, in this case, the Beidou terminal can be selected to wake up the wind turbine controller to achieve typhoon resistance operation.

[0069] For example, the Beidou command machine of the Beidou communication system can send a remote control command to the Beidou server (for example, Beidou satellite). After receiving the remote control command, the Beidou server can send a start command to the Beidou terminal. After receiving the start command, the Beidou terminal can feedback the successful reception command to the Beidou command machine through the Beidou server, and can establish communication with the anti-typhoon controller. The anti-typhoon controller can establish communication with the ring network switch and the remote I / O module of the unit control system, and the remote I / O module controls the relay of the fan controller to close and wake up the fan controller. The fan controller can start the diesel engine and control the circuit breaker of the diesel engine to close, so that the anti-typhoon command provided by the anti-typhoon controller can eventually realize the anti-typhoon operation of the wind turbine through the Beidou communication system and the fan controller.

[0070] In step S342, when the communication link between the Beidou communication system and the remote input / output module is unavailable, the anemometer is selected. That is, in this case, the anemometer can be selected to wake up the wind turbine controller to achieve typhoon resistance operation.

[0071] For example, the anemometer can detect the current wind speed in real time and feed it back to the anti-typhoon controller. When the wind speed reaches the anti-typhoon trigger condition, the anti-typhoon controller can communicate with the remote I / O module of the unit control system, so that the remote I / O module controls the relay, and the 24V battery of the wind turbine provides the wind turbine controller with an input 24V DC power supply, and wakes up the wind turbine controller. The wind turbine controller starts the diesel engine and controls the diesel engine's circuit breaker to close, so that the anti-typhoon command provided by the anti-typhoon controller can eventually realize the anti-typhoon operation of the wind turbine through the anemometer and the wind turbine controller.

[0072] Therefore, no matter in the construction phase or the operation phase of the offshore wind power system, the offshore wind power system according to the embodiment of the present disclosure can reliably perform typhoon resistance operations.

[0073] Figure 4 is a block diagram showing an offshore wind power system according to an embodiment of the present disclosure.

[0074] Reference Figure 4 The offshore wind power system 100 may include a power supply module 110 , a selection module 120 , a communication module 130 and an execution module 140 .

[0075] The power supply module 110 may be configured to supply power to at least one of the remote input / output module, the anti-typhoon controller, the Beidou communication system and the anemometer in the offshore wind power system through the storage battery. Therefore, when the offshore wind power system encounters a typhoon, the remote input / output module, the anti-typhoon controller, the Beidou communication system and the anemometer in the offshore wind power system may be supplied with power through the storage battery to cope with the impact of the typhoon.

[0076] In one embodiment, the power supply module 110 may be specifically configured to: power the remote input / output module of the wind turbine generator set of the offshore wind power system through the battery of the wind turbine generator set of the offshore wind power system, and power at least one of the anti-typhoon controller, Beidou communication system and anemometer of the offshore wind power system through the battery of the diesel generator of the offshore wind power system. Therefore, in the embodiment of the present disclosure, the battery of the wind turbine generator set and the battery of the diesel generator are used to power different components respectively, instead of using a single battery to power all components, so as to maximize the working time of each component and improve the overall power supply efficiency.

[0077] The selection module 120 may be configured to select one of the SCADA system, the Beidou terminal, and the anemometer based on the availability of the SCADA system and the Beidou communication system. When encountering a typhoon, the control method of the offshore wind power system according to an embodiment of the present disclosure may first check the availability of the communication link between the SCADA system and the Beidou communication system and the remote input / output module before performing the anti-typhoon operation, so that when one of the communication link between the SCADA system and the remote input / output module and the communication link between the Beidou communication system and the remote input / output module is unavailable, communication is not performed through the corresponding communication link, thereby improving the communication efficiency of the anti-typhoon operation and avoiding unnecessary time loss.

[0078] The communication module 130 may be configured to communicate with the anti-typhoon controller based on a selected one of the SCADA system, the Beidou terminal and the anemometer. The execution module 140 may be configured to execute the anti-typhoon strategy through the anti-typhoon controller. The control method of the offshore wind power system according to an embodiment of the present disclosure may select one of the SCADA system, the Beidou terminal and the anemometer based on the availability of the communication link between the SCADA system and the Beidou communication system and the remote input / output module, and execute the anti-typhoon strategy based on the selected one of the SCADA system, the Beidou terminal and the anemometer, so that the anti-typhoon operation can be reliably performed.

[0079] In the case where the offshore wind power system is in the construction stage, the power supply module 110 can be configured to: when no typhoon warning is received, power at least one of the remote input / output module, the anti-typhoon controller, the Beidou communication system and the anemometer in the offshore wind power system through the battery. Therefore, according to an embodiment of the present disclosure, when it is in the typhoon season, because the offshore wind power system may frequently encounter typhoons, the offshore wind power system may perform anti-typhoon operations when a typhoon warning is received, or may power at least one of the remote input / output module, the anti-typhoon controller, the Beidou communication system and the anemometer in the offshore wind power system through the battery when no typhoon warning is received, thereby preparing for the arrival of the typhoon.

[0080] When the offshore wind power system is in the construction stage, the selection module 120 can be configured to select one of the Beidou terminal and the anemometer based only on the availability of the communication link between the Beidou communication system and the remote input / output module. Therefore, when the offshore wind power system is in the construction stage, it is not necessary to judge the availability of the communication link between the SCADA system and the remote input / output module, but only to judge the availability of the communication link between the Beidou communication system and the remote input / output module; because the SCADA system needs to cooperate with the remote input / output module to operate, during the construction stage of the offshore wind power system when the SCADA system and / or the remote input / output module are not available, it is not necessary to select the SCADA system, but only to select one of the Beidou terminal and the anemometer, thereby improving the operating efficiency.

[0081] In the case where the offshore wind power system is in the construction stage, the communication module 130 may be configured to: communicate with the anti-typhoon controller based on the selected one of the Beidou terminal and the anemometer, and execute the anti-typhoon strategy. The control method of the offshore wind power system according to an embodiment of the present disclosure may select one of the Beidou terminal and the anemometer based on the availability of the communication link between the Beidou communication system and the remote input / output module, and execute the anti-typhoon strategy based on the selected one of the Beidou terminal and the anemometer, so that the anti-typhoon capability of the offshore wind power system during the construction stage can be achieved.

[0082] When the offshore wind power system is in the operation stage, the power supply module 110 can be configured to: when a typhoon warning is received, determine whether the power grid is powered off; in response to determining that the power grid is powered off, check whether the communication link between the SCADA system and the Beidou communication system and the remote input / output module is available, and power at least one of the remote input / output module, the anti-typhoon controller, the Beidou communication system and the anemometer in the offshore wind power system through the battery. Therefore, it can be determined whether the power grid is powered off before performing other processing, so as to more effectively deal with the typhoon. In addition, when encountering a typhoon, the control method of the offshore wind power system according to an embodiment of the present disclosure can first check the availability of the communication link between the SCADA system and the Beidou communication system and the remote input / output module before performing the anti-typhoon operation, so that when the communication link between the SCADA system and the remote input / output module and the communication link between the Beidou communication system and the remote input / output module are unavailable, communication is not performed through the corresponding communication link, so that the communication efficiency of the anti-typhoon operation can be improved and unnecessary time loss can be avoided.

[0083] In addition, the power supply module 110 can also be configured to: in response to determining that the power grid is powered off, determine whether the diesel generator is working; in response to determining that the diesel generator is not working, switch in the photovoltaic power generation system, and use the photovoltaic power generation system to charge the batteries of the wind turbine generator set of the offshore wind power system and the batteries of the diesel generator of the offshore wind power system; in response to determining that the power grid is not powered off or determining that the diesel generator is working, switch out the photovoltaic power generation system. In addition, the power supply module is also configured to: in response to determining that the diesel generator is working, use the diesel generator to charge the batteries of the wind turbine generator set of the offshore wind power system and the batteries of the diesel generator. Therefore, when the offshore generator set is off-grid for a long time, the off-grid standby time of the diesel generator can be extended and the diesel reserve of the diesel generator can be reduced.

[0084] When the offshore wind power system is in the operation stage, the selection module 120 can be configured to: when the communication link between the SCADA system and the remote input / output module is available, select the SCADA system to communicate with the anti-typhoon controller through the remote input / output module. For example, when the communication link between the SCADA system and the remote input / output module is available, the anti-typhoon command provided by the anti-typhoon controller can be transmitted to the remote input / output (I / O) module of the unit control system through the ring network switch of the unit control system through the SCADA system as the central control, and the remote I / O module controls the relay of the wind turbine controller to close, and the 24V battery of the wind turbine generator set provides the wind turbine controller with an input 24V direct current (DC) power supply, wakes up the wind turbine controller, and the wind turbine controller starts the diesel engine and controls the closing of the circuit breaker of the diesel engine, so that the anti-typhoon command provided by the anti-typhoon controller can finally realize the anti-typhoon operation of the wind turbine through the SCADA system and the wind turbine controller. In addition, the selection module 120 may be further configured to select one of the Beidou terminal and the anemometer to communicate with the anti-typhoon controller based only on the availability of the Beidou communication system when the communication link between the SCADA system and the remote input / output module is unavailable.

[0085] Whether the offshore wind power system is in the construction stage or the communication link between the SCADA system and the remote input / output module is unavailable, the selection module 120 can be configured to: select the Beidou terminal when the communication link between the Beidou communication system and the remote input / output module is available; and select the anemometer when the communication link between the Beidou communication system and the remote input / output module is unavailable.

[0086] For example, the Beidou command machine of the Beidou communication system can send a remote control command to the Beidou server (for example, Beidou satellite). After receiving the remote control command, the Beidou server can send a start command to the Beidou terminal. After receiving the start command, the Beidou terminal can feedback the successful reception command to the Beidou command machine through the Beidou server, and can establish communication with the anti-typhoon controller. The anti-typhoon controller can establish communication with the ring network switch and the remote I / O module of the unit control system, and the remote I / O module controls the relay of the fan controller to close and wake up the fan controller. The fan controller can start the diesel engine and control the circuit breaker of the diesel engine to close, so that the anti-typhoon command provided by the anti-typhoon controller can eventually realize the anti-typhoon operation of the wind turbine through the Beidou communication system and the fan controller. For another example, the anemometer can detect the current wind speed in real time and feedback it to the anti-typhoon controller. When the wind speed reaches the anti-typhoon triggering condition, the anti-typhoon controller can communicate with the remote I / O module of the unit control system, so that the remote I / O module controls the relay, and the 24V battery of the wind turbine generator set provides the wind turbine controller with an input 24V DC power supply, and wakes up the wind turbine controller. The wind turbine controller starts the diesel engine and controls the circuit breaker of the diesel engine to close, so that the anti-typhoon command provided by the anti-typhoon controller can eventually realize the anti-typhoon operation of the wind turbine through the anemometer and the wind turbine controller. Therefore, whether in the construction stage or the operation stage of the offshore wind power system, the offshore wind power system according to the embodiment of the present disclosure can reliably perform anti-typhoon operations.

When the processor 210 executes the computer program stored in the memory 220, the control method of the offshore wind power system as described above can be implemented.
