Description

Technical Field

[0001] The present application relates to the technical field of offshore wind power generation, and particularly to a debugging method, device, equipment and medium for an offshore wind turbine based on black start. Background Art

[0002] If the external power grid of an offshore wind farm loses power connection, the offshore wind farm will be in an island state and cannot guarantee its own internal power supply. In the long-term power outage state, it will inevitably cause damage to the offshore substation and wind turbine equipment. It is necessary to provide an operation and maintenance power supply for the wind turbines after the wind farm loses external power or before it is powered on, so as to avoid damage to the wind turbines.

[0003] In the related art, after the wind farm loses external power or before it is powered on, a diesel generator is usually used to drive the wind turbines in the wind farm to start, so as to realize the debugging and restart of the wind turbines. However, when using a diesel generator as a black start power source, the diesel generator needs to burn diesel, causing air pollution. Summary of the Invention

[0004] In order to realize the black start of the wind turbines and reduce air pollution during the black start of the wind turbines, the present application provides a debugging method, device, equipment and medium for an offshore wind turbine based on black start.

[0054] The present application will be further described in detail below with reference to the accompanying drawings. An embodiment of the present application provides a commissioning method for an offshore wind turbine based on black start. The commissioning method for the offshore wind turbine based on black start can be executed by an electronic device, which can be a server or a terminal device. The server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0055] In this embodiment, the black start system includes a renewable energy power generation subsystem, an energy storage subsystem, a diesel generator, and a control subsystem; the renewable energy power generation subsystem, the energy storage subsystem, and the diesel generator are all wirelessly connected to the control subsystem, and the renewable energy power generation subsystem, the energy storage subsystem, and the diesel generator are all electrically connected to the wind turbine and provide power for the commissioning of the wind turbine.

[0056] As an alternative implementation manner of this embodiment, the renewable energy power generation subsystem can be photovoltaic power generation or tidal energy power generation. It should be noted that the renewable energy power generation subsystem can be an already built and mature power generation subsystem or a small renewable energy power generation subsystem, that is, a power generation subsystem that can be directly used without commissioning. For example, a generator with photovoltaic power generation.

[0057] As an alternative implementation manner of this embodiment, the energy storage subsystem can be an energy storage device using flywheel energy storage, a super capacitor using super capacitor energy storage, or a redox flow battery using chemical energy storage. In this embodiment, a redox battery using chemical energy storage is selected. The energy storage subsystem includes multiple energy storage units, and the multiple energy storage units are respectively electrically connected to the renewable energy power generation subsystem and the wind turbine. When replenishing electric energy for the energy storage unit, the energy storage unit can receive the electric energy generated by the renewable energy power generation subsystem and the electric energy generated by the wind turbine that has been commissioned.

[0058] In this embodiment, both the renewable energy power generation subsystem and the energy storage subsystem can meet the requirements for commissioning the offshore wind turbine during normal operation.

[0059] As shown in Figure 1 A commissioning method for an offshore wind turbine based on black start is applied to the black start system. The main process of this method is described as follows (Steps S100 - S400):

[0060] Step S100, in response to a wind turbine commissioning command, obtain the commissioning level of each wind turbine in the wind farm.

[0061] In this embodiment, before the wind turbine generator is powered on, the wind turbine generator can be debugged by manually sending a debug command. When the wind turbine generator is running, the black start system detects that the wind turbine generator has lost external power and needs the black start system to re-debug and start the wind turbine generator. At this time, the black start system can automatically obtain the debug command of the wind turbine generator and then debug the wind turbine generator.

[0062] Referring to Figure 2 , before obtaining the debug level of each wind turbine generator in the wind farm, it is necessary to determine the debug level of each wind turbine generator, which specifically includes the following steps:

[0063] Step S101, obtain the location information and power generation level of all wind turbine generators in the wind farm.

[0064] In this embodiment, the location where the wind turbine generator is placed in the offshore wind farm needs to be calculated and investigated. The location where the wind turbine generator is placed is affected by the wind speed and wind direction, and the power generation of the wind turbine generator is also affected by the wind direction and wind speed. Therefore, it is necessary to obtain the power generation level and location information of the wind turbine generators at different locations.

[0065] Specifically, according to the power generation scale of the wind farm, the power generation of each wind turbine generator is determined. In a wind farm, there are not only wind turbine generators with one power generation level. Therefore, it is necessary to obtain wind turbine generators with different power generations and divide the levels according to the power generation of these wind turbine generators with different power generations. For example: if the power generation scale of a wind farm is 300 MW, it may include 20 wind turbine generators with 4 MW, 20 wind turbine generators with 5 MW, and 20 wind turbine generators with 6 MW. Among them, 4 MW is the first power generation level, 5 MW is the second power generation level, and 6 MW is the third power generation level. The above data is only for illustrative purposes.

[0066] Step S102, obtain the wind speed level within a preset time period based on the location information.

[0067] Since the location of each wind turbine generator is different, the wind speed at each location may be different. It is necessary to divide the levels according to the different wind speeds. For example, the wind speed range in the wind farm is 5 m / s to 8 m / s, where 5 m / s to 6 m / s is the first wind speed level, 6 m / s to 7 m / s is the second wind speed level, and 7 m / s to 8 m / s is the third wind speed level. The above wind speeds are all the average wind speeds at the location of the wind turbine generator within one hour.

[0068] It should be noted that at least one wind turbine generator is set in the area with the same wind speed level in a wind farm, and the number of wind turbine generators is determined by the size of the area with the same wind speed level and the stability of the wind direction.

[0069] Step S103: Determine the commissioning level of the wind turbine based on the wind speed level and the power generation level.

[0070] Specifically, obtain the wind speed level and the power generation level of each wind turbine; obtain different preset weight values corresponding to the wind speed level and the power generation level of each wind turbine respectively; determine the commissioning level of the wind turbine based on the preset weight value corresponding to the wind speed level of each wind turbine and the weight value corresponding to the power generation level.

[0071] In this embodiment, taking 20 4MW wind turbines, 20 5MW wind turbines, and 20 6MW wind turbines as an example, the wind speed range in the wind farm is 5m / s to 8m / s:

[0072] In this wind farm, the 4MW wind turbines are in the first power generation level, the 5MW wind turbines are in the second power generation level, the 6MW wind turbines are in the third power generation unit, 5m / s to 6m / s is the first wind speed level, 6m / s to 7m / s is the second wind speed level, 7m / s to 8m / s is the third wind speed level. Assign the first weight value to the first wind speed level, the second weight value to the first power generation level, the third weight value to the second wind speed level, the fourth weight value to the second power generation level, the fifth weight value to the third wind speed level, and the sixth weight value to the third power generation level.

[0073] In this embodiment, set the first weight value to 0.4, the second weight value to 0.5, the third weight value to 0.6, the fourth weight value to 0.7, the fifth weight value to 0.8, and the sixth weight value to 0.9. When all the wind turbines in the wind farm need to be commissioned, it is necessary to sort all the wind turbines according to the weight values. The commissioning level of the wind turbine is determined by the product of the weight value corresponding to the power generation level and the weight value corresponding to the wind speed level. For example, the weight of a 4MW wind turbine in a wind speed environment of 5m / s to 6m / s is 0.2, which is obtained by multiplying the first weight value and the second weight value. When the product of the weight value corresponding to the power generation level of the wind turbine and the weight value corresponding to the wind speed level is less than 0.3, the commissioning level of the current wind turbine is determined as the first commissioning level; when the product of the weight value corresponding to the power generation level of the wind turbine and the weight value corresponding to the wind speed level is greater than or equal to 0.3 and less than 0.5, the commissioning level of the current wind turbine is determined as the second commissioning level; when the product of the weight value corresponding to the power generation level of the wind turbine and the weight value corresponding to the wind speed level is greater than or equal to 0.5, the commissioning level of the current wind turbine is determined as the third commissioning level.

[0074] Step S200: Develop a commissioning strategy for the wind turbine based on the commissioning level.

[0075] Specifically, obtain the basic information of the wind turbines; sort all the wind turbines based on the basic information and the debugging level to obtain a sorting result; formulate a debugging strategy based on the sorting result.

[0076] In this embodiment, when building a wind farm, due to the construction progress of the wind farm, there may be wind turbines that are completed first. In order to be put into use as soon as possible, it is possible to carry out construction and debugging simultaneously. At this time, if debugging the wind turbines that have been built, it is necessary to obtain the basic information of the wind turbines, and the basic information includes the completion time and acceptance time of the wind turbines. Then, sort the wind turbines according to the basic information of the wind turbines and the debugging level to obtain a sorting result. Among them, for different wind turbines at the same debugging level, they are sorted again according to the weight value of the wind turbines. If the weight values are the same, it is necessary to determine the debugging order of the wind turbines according to the completion time and acceptance time of the wind turbines.

[0077] For example, the weight of a 4MW wind turbine in a wind speed environment of 7m / s to 8m / s is 0.36, while the weight of a 5MW wind turbine in a wind speed environment of 6m / s to 7m / s is 0.42. Since both of these two wind turbines are in the second debugging level, but the weight of the 5MW wind turbine is greater than the weight of the 4MW wind turbine, it is necessary to debug the 5MW wind turbine first and then the 4MW wind turbine; if two 5MW wind turbines are completed simultaneously in a wind speed environment of 6m / s to 7m / s, but the acceptance time of one of the wind turbines is later than that of the other wind turbine, then the debugging ranking of the wind turbine with the later acceptance time lags behind that of the wind turbine with the earlier acceptance time. This can give the wind turbine with the later acceptance time more time for adjustment, so as to ensure that the wind turbine is successfully debugged at one time.

[0078] Step S300, determine the start-up strategy of the black start system based on the debugging strategy, and the start-up strategy includes controlling the start of the renewable energy subsystem.

[0079] Specifically, obtain the current status information of the renewable energy power generation subsystem and the energy storage subsystem; judge whether both the renewable energy power generation subsystem and the energy storage subsystem can be used based on the current status information; if both the renewable energy power generation subsystem and the energy storage subsystem can be used, then allocate the renewable energy power generation subsystem and the energy storage subsystem to obtain an allocation result; formulate a power supply strategy for the renewable energy power generation subsystem and the energy storage subsystem according to the allocation result and the debugging strategy, and the power supply strategy is the first start-up strategy.

[0080] In this embodiment, a black start system is required to commission the wind turbine units. However, due to the limitations of many factors such as the environment on the renewable energy power generation subsystem and the energy storage subsystem, it is necessary to obtain the current status information of the renewable energy power generation subsystem and the energy storage subsystem in real time so as to be able to respond to emergencies in the wind farm in a timely manner. Among them, the current status information includes operation status information and output power information.

[0081] Furthermore, when the operation status information and output power information of both the renewable energy power generation subsystem and the energy storage subsystem are normal, the renewable energy power generation subsystem and the energy storage subsystem are allocated based on the number of wind turbine units to be commissioned. For example, when the number of wind turbine units to be adjusted is 10, since the power generation of the energy storage subsystem is stable, the energy storage subsystem is preferentially allocated. When the power storage of the energy storage subsystem can only support the commissioning of 6 wind turbine units, the remaining 4 wind turbine units are powered for commissioning by the renewable energy power generation subsystem. At this time, the first start-up strategy includes that the energy storage subsystem powers 6 wind turbine units, and the renewable energy power generation subsystem powers 4 wind turbine units; when the power storage of the energy storage subsystem can support the commissioning of 10 wind turbine units, all 10 wind turbine units are powered by the energy storage subsystem. At this time, the first start-up strategy includes that the energy storage subsystem powers 10 wind turbine units; when the power storage of the energy storage subsystem cannot meet the commissioning of 1 wind turbine unit, all 10 wind turbine units are powered for commissioning by the renewable energy power generation subsystem. At this time, the first start-up strategy includes that the renewable energy subsystem powers 10 wind turbine units for commissioning.

[0082] As another alternative embodiment of this embodiment, another allocation method is used to allocate the renewable energy power generation subsystem and the energy storage subsystem, that is, a power supply strategy is jointly formulated according to the commissioning strategy and the allocation result. For example:

[0083] When 10 wind turbine units need to be powered for commissioning, and the commissioning levels of these 10 wind turbine units are all between the first commissioning level and the second commissioning level, the energy storage subsystem is used to power the commissioning of the wind turbine units at the first commissioning level, and the renewable energy power generation subsystem is used to commission the wind turbine units at the second commissioning level. When the power storage of the energy storage subsystem is not sufficient to power the commissioning of all the wind turbine units at the first commissioning level, the renewable energy power generation subsystem is used to commission the wind turbine units.

[0084] In this embodiment, when both the renewable energy power generation subsystem and the energy storage subsystem cannot be used, obtain the current environmental information in the wind farm; based on the current environmental information, determine whether it is necessary to adopt a second startup strategy to commission the wind turbine, and the second startup strategy includes using a diesel generator for power generation; if so, adopt the second startup strategy to commission the wind turbine; if not, send an alarm message to the corresponding terminal of the staff to give a warning to the staff.

[0085] Specifically, when the renewable energy power generation subsystem and the energy storage subsystem cannot operate, the current environmental information of the wind farm can be obtained through the meteorological information released by the Internet and the meteorological bureau. The environmental information includes cloud and rain map information, typhoon information, and wind direction and speed information within a preset distance range of the wind farm. When there is an environment where it is not suitable to adopt the second startup strategy to commission the wind turbine, it is necessary to send an alarm message to the corresponding terminal of the staff to start a warning to the staff, reducing the possibility of danger caused by the environment.

[0086] Step S400, commission the wind turbine according to the startup strategy.

[0087] Specifically, before commissioning the wind turbine, it is also necessary to determine whether the wind turbine is being commissioned for the first time; if the wind turbine is being commissioned for the first time, adopt the first startup strategy to commission the wind turbine; if the wind turbine is not being commissioned for the first time, obtain the historical startup strategy of the wind turbine; determine the third startup strategy based on the historical startup strategy and the first startup strategy, and determine the third startup strategy as the startup strategy of the current wind turbine.

[0088] In this embodiment, since a part of the wind turbines have been commissioned, but due to the reason of the external network power supply, the wind turbines have stopped. At this time, it is necessary to use the black start system to commission the wind turbines again. Then, for the wind turbines that have been commissioned, obtain the historical startup strategy. The historical startup strategy includes using the renewable energy power generation subsystem for black start, using the energy storage subsystem for black start, and using a diesel generator for black start. Then, determine the third startup strategy according to the historical startup strategy and the first startup strategy. For example:

[0089] A 4MW wind turbine has been running for some time, but due to the power outage of the external power grid, the wind turbine has stopped running. At this time, the historical startup strategy of this wind turbine can be obtained, and the wind turbine can be started according to the historical startup strategy. However, when the historical startup strategy of this wind turbine is the second startup strategy, obtain the first startup strategy again, and use the first startup strategy at this time as the third startup strategy, and start the wind turbine according to the third startup strategy.
