Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and in particular to a yaw control method, device, equipment and medium for a generator set. Background Art

[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. Using wind power to generate electricity is very environmentally friendly and has huge wind energy reserves, so it is increasingly valued by countries around the world.

[0003] However, wind power generation has many restrictions, such as regional restrictions, noise impact and wind intensity. The first two influencing factors can be solved by choosing a place with wind all year round and far away from people, while wind intensity is a factor that cannot be controlled by humans. Therefore, power generation can only be carried out by adjusting the angle of the wind turbine.

Currently, manual control is generally adopted, that is, the yaw motor is manually controlled to change the angle according to the current wind force and direction.

[0065] The present application is further described in detail below in conjunction with the accompanying drawings.

[0066] The embodiment of the present application provides a yaw control method for a generator set, which can be executed by an electronic device, which can be a server or a terminal device, wherein 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.

[0067] Figure 1 A schematic flow chart of a yaw control method for a generator set provided in an embodiment of the present application.

[0068] like Figure 1 As shown, the main process of the method is described as follows (steps S101 to S106):

[0069] Step S101, obtaining the wind turbine yaw circumference and division strategy of the wind turbine yaw area.

[0070] In this embodiment, the method is mounted on an electronic device and connected to a generator set through an electrical signal, thereby realizing yaw control of the generator set, and controlling each generator set individually to realize targeted regulation, thereby accurately controlling each generator set. The yaw area of ​​the wind turbine is the area where the generator set can rotate when the generator set rotates. The yaw circumference of the wind turbine is the circumference corresponding to the yaw area of ​​the wind turbine. Since the generator set is provided with a cable, it cannot achieve a 360-degree rotation. Therefore, different generator sets are provided with corresponding rotation angles according to actual usage conditions, and the sizes of the generator sets are also different, so that the circumferences are also different. When further processing is performed, it is necessary to determine the yaw circumference of the wind turbine corresponding to the yaw area of ​​the wind turbine of each generator set. The yaw circumference is calculated by information such as the radius and rotation angle of the generator set. The division strategy is the number of divisions of the yaw circumference of different wind levels, that is, under different circumference values, the number of yaw adjustment areas is different. The specific number of divisions needs to be set according to actual needs, and is not specifically limited here.

[0071] Step S102 : dividing the yaw circumference of the wind turbine into a plurality of yaw adjustment areas on an even basis based on a division strategy, and numbering the yaw adjustment areas to determine area numbers of the yaw adjustment areas.

[0072] For step S102, the number of regions for adjusting the wind turbine yaw area is determined based on the wind turbine yaw circumference and the division strategy; the regional circumference of the wind turbine yaw area is determined based on the wind turbine yaw circumference and the number of adjustment regions; a number of yaw adjustment regions of the wind turbine yaw area are determined based on the number of regions and the regional circumference; the extreme position of the wind turbine yaw area is obtained, and the order of region division is determined based on the extreme position; and the region number of each yaw adjustment region is determined based on the region division order.

[0073] In this embodiment, except when the yaw circumference of the wind turbine corresponding to the generator set is too large or too small, that is, in general, the number of adjustment areas determined according to the division strategy is 16, that is, when dividing the yaw adjustment area, the yaw circumference of the wind turbine is evenly divided into 16 parts, so as to obtain 16 yaw adjustment areas with the same circumference, and the area circumference is calculated directly by the yaw circumference of the wind turbine and the number of adjustment areas and the conventional calculation formula. In order to clarify the adjustment area when adjusting, each yaw adjustment area is numbered, that is, each yaw adjustment area has a unique area number. When determining the area number, the yaw adjustment area adjacent to the extreme position is taken as the first and last. When determining the first yaw adjustment area, the area division order can be directly confirmed, and then the area division is performed according to the area division order. For example, there are 16 yaw adjustment areas in total, and the area number of the first yaw adjustment area is set to 1, and then the area number of the yaw adjustment area adjacent to it is set to 2, until the area number of another yaw adjustment area adjacent to the extreme position is set to 16.

[0074] Furthermore, when determining the order of area division, the location information and environmental wind direction information of the generator set are obtained; the target environmental wind direction is determined based on the environmental wind direction information and preset determination rules; the extreme position is divided into an initial extreme position and an end extreme position based on the location information and the environmental wind direction; and the order of area division is determined based on the initial extreme position and the end extreme position.

[0075] During the use of the generator set, an initial position is generally set. The setting of the initial position is based on the environmental wind direction information. Different areas have different corresponding environmental wind directions. The initial position is the windward position of the usual environmental wind direction in the area. That is, if area A has an easterly wind for a long time, then the target environmental wind direction of area A is the easterly wind, and the initial position is set to the windward position of the easterly wind. Since there are two extreme positions, the extreme position close to the initial position is selected as the initial extreme position, and the other extreme position is used as the terminal extreme position. When sorting, the area division order is obtained from the initial extreme position to the terminal extreme position.

[0076] Step S103: determining a region target value of the yaw adjustment region based on the yaw adjustment region and the region number.

[0077] For step S103, the regional midpoint of the yaw adjustment area is determined based on the regional perimeter; the midpoint value of the yaw adjustment area is determined based on the area number, the regional perimeter and the regional midpoint, and the midpoint value is used as the regional target value of the yaw adjustment area.

[0078] In this embodiment, in order to facilitate adjustment and calculation, the regional midpoint of each yaw adjustment area is selected as the regional target value of the current yaw adjustment area. The regional midpoint is the middle point or center point of the yaw adjustment area. Since the regional perimeter has been determined, the regional midpoint is calculated according to the regional perimeter and midpoint calculation formula. After obtaining the regional midpoint of a yaw adjustment area, the midpoint value of each yaw adjustment area can be inferred according to the regional perimeter and the area number, and all midpoint values ​​are the regional target values ​​of the yaw adjustment area.

[0079] Step S104, obtaining environmental wind resource information, output power information and current area number.

[0080] In this embodiment, the environmental wind resource information is the wind direction and wind level in the current environment, such as level 6 east wind, level 3 north wind and level 4 west wind, etc. The output power information is the current power generation power of the generator set, and the current area number is the area number of the yaw adjustment area where the generator set is located.

[0081] Step S105, generating a yaw control scheme based on the environmental wind resource information, the output power information and the current area number.

[0082] For step S105, determine whether regional adjustment is required based on the environmental wind resource information and the output power information; if regional adjustment is required, determine the target yaw adjustment area based on the environmental wind resource information; obtain the target area number of the target yaw adjustment area; determine the target movement data based on the current area number and the target area number; generate a yaw control scheme based on the target area number, the current area number and the target movement data; if regional adjustment is not required, repeat the step of determining whether regional adjustment is required based on the environmental wind resource information and the output power information.

[0083] In this embodiment, whether regional adjustment is needed is judged based on environmental wind resource information and output power. When regional adjustment is needed, the target yaw adjustment area is determined based on the environmental wind resource information, and the target movement data is determined based on the yaw adjustment area. The target movement data is the motion curve when moving. The motion curve is calculated by the current area number, the target area number and the regional target value obtained above. The target curve is the action curve when the generator set is rotating. The calculated target movement data is bound to the target area number and the current area number to obtain the yaw control plan around the mouth.

[0084] When making adjustment judgments, obtain the working power range and the current wind turbine direction; determine whether the output power information is within the working power range; if the output power information is within the working power range, determine that no regional adjustment is required; if the output power information is outside the working power range, determine whether regional adjustment is required based on the environmental wind resource information and the working power range.

[0085] In this embodiment, in order to achieve the maximum power generation on the basis of ensuring the safety of the generator set, it is necessary to make regional adjustments in real time according to the current environmental wind resource information. First, a preliminary judgment is made based on the output power information, and a working power interval is set. When the output power information is in the working power interval, it means that the generator set is safe and can operate at the maximum power generation, so there is no need for regional adjustment. When the output power information is outside the working power interval, there are two situations. The first situation is that the output power information is less than the lower limit of the working power interval, and the generator set cannot operate at the maximum power generation. The second situation is that the output power information is greater than the upper limit of the working power interval, and the safety of the generator set cannot be guaranteed. Both situations require further regional adjustment judgments based on the environmental wind resource information.

[0086] First, determine whether the direction of the current wind turbine is the direction of maximum wind force according to the environmental wind resource information. If it is the direction of maximum wind force, in the first case, it is determined that no regional adjustment is required. Since it is already the direction of maximum wind force, only the corresponding output power information can be generated and no adjustment is required. In the second case, it is determined that regional adjustment is required. Since it has exceeded the upper limit value of the power operation area and is in the direction of maximum wind force, there are already safety issues and adjustments need to be made as soon as possible. If it is not the direction of maximum wind force, in the first case, it is determined that regional adjustment is required. Since it is not the direction of maximum wind force, greater output power information can be generated, so adjustment is required. In the second case, it is determined that no regional adjustment is required and shutdown processing is performed. Since it is not the direction of maximum wind force but has exceeded the upper limit value of the power operation area, it can be determined based on the actual wind conditions that when it is not the direction of maximum wind force but the wind is still very strong, it is difficult to find a location with low wind force, and the turbine is directly shut down.

[0087] When determining the target yaw adjustment area, the adjustment probability of the yaw adjustment area is calculated based on the environmental wind resource information; the standby yaw adjustment area is determined based on the adjustment probability; the number of the standby yaw adjustment areas is obtained; and the target yaw adjustment area is determined based on the number of areas and a preset selection strategy.

[0088] In this embodiment, the adjustment probability of each yaw adjustment area is calculated according to the Huangjing resource information collected in real time, where the adjustment probability refers to the probability of being suitable for adjustment to the yaw adjustment area, and a probability selection threshold is set, and the yaw adjustment area with an adjustment probability higher than the probability selection threshold is used as the standby yaw adjustment area, and the area number and the number of areas of each standby yaw adjustment area are determined, and the area number of the standby yaw adjustment area is used as the standby area number, and the standby area numbers are arranged in ascending order according to the size of the numerical value to generate a standby sequence, and the preset selection strategy is to determine whether the number of areas is an odd number or an even number, when the number of areas is an odd number, select the middle number of the standby sequence, and use the standby yaw adjustment area corresponding to the middle number as the target yaw adjustment area, and when the number of areas is an even number, select the one with the smaller standby area number of the two middle numbers of the standby sequence, and use the standby yaw adjustment area corresponding to the one with the smaller standby area number as the target yaw adjustment area.

[0089] Step S106, performing yaw control on the generator set based on the yaw control solution.

[0090] In this embodiment, the generator set is controlled to perform position regulation according to the target movement data, the target area number and the current area number in the yaw control scheme, thereby achieving yaw control of the generator set and displaying the corresponding information.
