Detailed Description
Various example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.
Fig. 1 shows a flowchart of a typhoon warning method of a wind farm according to an exemplary embodiment of the invention.
Referring to fig. 1, in step S10, typhoon-related data is acquired.
By way of example, the typhoon-related data may include, but is not limited to, at least one of: the method comprises the following steps of moving paths of typhoons, wind speeds of the typhoons, wind directions of the typhoons, gust information, rainfall, thunder information, information of at least one wind circle of the typhoons, and time of the at least one wind circle reaching the wind power plant.
In a preferred example, the typhoon related data may be obtained from a typhoon data source external to the wind farm by the reverse isolation device, e.g. via the internet. Here, the typhoon data source may be a provider of typhoon-related data, which may acquire and provide typhoon-related data from relevant meteorological units or internet platforms.
Preferably, the steps of determining the typhoon early warning level and determining the early warning strategy for typhoons of the wind farm can be performed inside the wind farm, that is, the steps of determining the typhoon early warning level and determining the early warning strategy for typhoons of the wind farm are performed based on a local area network inside the wind farm. The reverse isolation device is used as a device in the wind power plant, can be used for realizing physical isolation between the interior and the exterior of the wind power plant, can ensure the safety of communication in the wind power plant, and can also effectively prevent data in the wind power plant from leaking.
In step S20, a typhoon warning level of the wind farm is determined based on the wind farm related data and the acquired typhoon related data.
As an example, a supervisory control and data acquisition (SCADA) system may be disposed in the wind farm, and the SCADA system may perform data acquisition and control instruction issue on the wind turbine generators in the wind farm, and may display the operating state and typhoon related data of the wind turbine generators on a monitoring platform thereof for monitoring by workers. In this case, the location of the wind farm may be obtained from the SCADA system.
According to the typhoon early warning method for the wind farm, the typhoon related data obtained from the typhoon data source outside the wind farm and the wind farm related data obtained from the SCADA system of the wind farm can be analyzed and processed to determine the early warning strategy for the typhoon. As a non-limiting example, the typhoon warning method of a wind farm according to an exemplary embodiment of the invention may be performed in a SCADA system of a wind farm.
Preferably, the wind farm related data may include a location of the wind farm, in which case the step of determining the typhoon early warning level of the wind farm based on the wind farm related data and the obtained typhoon related data may include: and determining the typhoon early warning level according to whether the typhoon related data is acquired or not, whether the moving path of the typhoon passes through the position of the wind power plant and/or the wind circle level of the typhoon at the position of the wind power plant. Here, the typhoon early warning level may indicate an influence of the typhoon on the wind farm, and the higher the early warning level of the typhoon, the greater the influence of the typhoon the wind farm.
By way of example, a typhoon warning level from low to high may include, but is not limited to: no typhoon early warning, typhoon first-level early warning, typhoon second-level early warning, typhoon third-level early warning and typhoon fourth-level early warning. The following describes the determination of the warning level of each typhoon.
For example, the way of determining that there is no typhoon warning may be: when the typhoon related data is not acquired, the fact that no typhoon exists can be indicated, and when the typhoon does not exist, the typhoon early warning level can be determined to be no typhoon early warning.
The mode of determining the typhoon first-level early warning can be as follows: when the moving path of the typhoon does not pass through the position of the wind power plant, namely when the position of the wind power plant is out of the range covered by the set wind ring on the moving path of the typhoon, the typhoon early warning grade can be determined to be typhoon first-grade early warning. As an example, the set wind circle may refer to a wind circle of a first level (i.e., a wind circle having the lowest average wind force in the typhoon), but the present invention is not limited thereto, and may refer to wind circles of other levels. For example, when the position of the wind power plant is not in the range covered by the wind circle of the first level in the moving path of the typhoon, the typhoon early warning level can be determined as typhoon first-level early warning.
The mode of determining the typhoon secondary early warning can be as follows: in one example, when the moving path of the typhoon passes through the position of the wind farm, if the circle level of the typhoon at the position of the wind farm is the first level, that is, when the moving path of the typhoon passes through the position of the wind farm and the position of the wind farm is within the range covered by the circle of the first level on the moving path of the typhoon (at this time, the position of the wind farm should be out of the range covered by the circle of the second level), it is determined that the typhoon early warning level is the typhoon secondary early warning. In another example, when the moving path of the typhoon passes through the position where the wind farm is located, if the time that a predetermined wind circle of the at least one wind circle of the typhoon reaches the wind farm is greater than a first set time, the typhoon pre-warning level may be determined as typhoon secondary pre-warning. Here, the predetermined wind circle may refer to any one of the at least one wind circle of the typhoon.
The mode of determining the third-level typhoon warning can be as follows: in one example, when the moving path of the typhoon passes through the position of the wind farm, if the circle level of the typhoon at the position of the wind farm is the second level, that is, when the moving path of the typhoon passes through the position of the wind farm and the position of the wind farm is within the range covered by the circle of the second level on the moving path of the typhoon (at this time, the position of the wind farm should be out of the range covered by the circle of the third level), it is determined that the typhoon early warning level is the typhoon third-level early warning. Here, the average wind force of the second level of the windband may be greater than the average wind force of the first level of the windband. In another example, when the moving path of the typhoon passes through the position where the wind farm is located, if the time for a predetermined wind circle of the at least one wind circle of the typhoon to reach the wind farm is less than a first set time and greater than a second set time, the typhoon early warning level may be determined as a typhoon tertiary early warning. Here, the time length of the second set time may be greater than the time length of the first set time.
The mode of determining the typhoon four-level early warning can be as follows: in one example, when the moving path of the typhoon passes through the position of the wind farm, if the circle level of the typhoon at the position of the wind farm is a third level, that is, when the moving path of the typhoon passes through the position of the wind farm and the position of the wind farm is within the range covered by the circle of the third level on the moving path of the typhoon, it may be determined that the typhoon early warning level is typhoon four-level early warning. Here, the average wind force of the third level of the windband may be greater than the average wind force of the second level of the windband. In another example, when the moving path of the typhoon passes through the position of the wind farm, if the time for a predetermined wind circle in the at least one wind circle of the typhoon to reach the wind farm is less than a second set time and greater than a third set time, the typhoon early warning level can be determined as the typhoon four-stage early warning. Here, the time length of the first set time may be greater than the time length of the second set time.
It should be understood that, in the exemplary embodiment of the present invention, the division of the typhoon early warning level into five levels is only an example, and a person skilled in the art may adjust the division of the typhoon early warning level and modify the name of the typhoon early warning level according to the actual operation condition of the wind farm and the needs of the owner. In addition, technicians in the field can adjust early warning strategies corresponding to each typhoon early warning level, so that the power generation time of the wind generating set can be prolonged to the maximum extent, and the safe operation of the wind generating set can be ensured.
In step S30, an early warning strategy for typhoon of the wind farm is determined according to the determined typhoon early warning level of the wind farm. Preferably, different typhoon warning levels may correspond to different warning strategies. However, the present invention is not limited thereto, and the same warning strategy may be adopted for two different typhoon warning levels. Here, the early warning strategy for typhoons in the wind farm may include a control strategy made for typhoons on wind generating sets in the wind farm and/or an early warning and deployment strategy for operation and maintenance personnel of the wind farm.
For example, the early warning strategy corresponding to the non-typhoon early warning and the early warning strategy corresponding to the typhoon primary early warning can both be used for keeping the current operation state of the wind generating set in the wind power plant.
The early warning strategy corresponding to the typhoon secondary early warning can be that at a first preset time before the wind ring of the first level of typhoon reaches the wind power plant, the wind power generator set in the wind power plant is controlled to carry out shutdown self-checking, the wind power generator set is controlled to recover to operate after the shutdown self-checking is finished, and/or information used for indicating artificial operation and maintenance for the wind power generator set is displayed to operation and maintenance personnel of the wind power plant.
It should be understood that when it is predicted that the wind circle of the first level of the typhoon will pass through the position of the wind farm, there is a long time until the wind circle of the first level reaches the position of the wind farm, and as an example, the time length corresponding to the first predetermined time may be ten hours, tens of hours, days, or even longer, so that the wind farm has a sufficient preparation time. At the moment, the wind generating set can be controlled to carry out self-checking so as to ensure the safety of the wind generating set when typhoon comes. Optionally, the operation and maintenance personnel can be prompted to enter an emergency response process (that is, the operation and maintenance personnel are prompted to arrive at respective posts to enter a preparation state for the arrival of the oncoming typhoon), and when a problem is detected in the process of controlling the wind generating set to perform self-inspection, the operation and maintenance personnel in charge of the wind generating set with the problem can be prompted to perform corresponding treatment in time.
By way of example, the self-test of the wind turbine generator system may include, but is not limited to, detecting a status, fault information, etc. of components of the wind turbine generator system, and may store data related to the self-test (e.g., information indicating the status of the components, fault information, information indicating whether the self-test is complete).
As an example, the self-test of the wind park may include, but is not limited to, at least one of: the method comprises the following steps of testing the emergency feathering function of the variable pitch, testing the locking function of a variable pitch locking pin, testing the function of a yawing brake mechanism, testing the function of a yawing drive mechanism, monitoring the yawing cable twisting angle, detecting the fault state of a wind vane of an anemoscope and detecting communication.
The early warning strategy corresponding to the typhoon three-level early warning can be that the wind generating set in the wind power plant is controlled to enter a typhoon control mode at a second preset time before the wind circle of the second level of the typhoon reaches the wind power plant, and/or information related to the typhoon is displayed to operation and maintenance personnel of the wind power plant.
Preferably, the time length corresponding to the second predetermined time may be less than the time length corresponding to the first predetermined time, and generally, the time length corresponding to the second predetermined time may be several hours, at this time, the wind generating set in the wind farm may be controlled to enter a typhoon control mode, and/or information related to typhoon may be displayed to operation and maintenance personnel of the wind farm. Here, it should be understood that the time lengths corresponding to the first predetermined time and the second predetermined time may be adjusted by those skilled in the art according to the requirements of the wind farm and the owner.

Fig. 3 shows a block diagram of a typhoon warning device of a wind farm according to an exemplary embodiment of the invention.
As shown in fig. 3, the typhoon early warning device of the wind farm according to the exemplary embodiment of the present invention includes a typhoon data acquisition module 10, a typhoon early warning level determination module 20, and an early warning policy determination module 30.
Specifically, the typhoon data acquisition module 10 acquires typhoon-related data.
By way of example, the typhoon related data may include, but is not limited to, at least one of: the method comprises the following steps of obtaining the moving path of the typhoon, the wind speed of the typhoon, the wind direction of the typhoon, gust information, rainfall, thunder information, information of at least one wind circle of the typhoon and the time of the at least one wind circle reaching the wind power plant.
In a preferred example, typhoon-related data may be acquired by typhoon data acquisition module 10 from a typhoon data source external to the wind farm by a reverse isolation device, e.g. typhoon-related data may be acquired by typhoon data acquisition module 10 from a typhoon data source external to the wind farm via the internet by a reverse isolation device. The reverse isolation device is used as a device in the wind power plant, can be used for realizing physical isolation between the interior and the exterior of the wind power plant, can ensure the safety of communication in the wind power plant, and can also effectively prevent data in the wind power plant from leaking.
The typhoon early warning level determination module 20 determines the typhoon early warning level of the wind farm based on the wind farm related data and the obtained typhoon related data.
As a non-limiting example, a SCADA system may be arranged in the wind farm, and the typhoon warning device of the wind farm according to an exemplary embodiment of the invention may be part of the SCADA system. That is, the typhoon data acquisition module 10, the typhoon early warning level determination module 20 and the early warning policy determination module 30 of the exemplary embodiment of the present invention may be modules integrated in the SCADA system.
Preferably, the wind farm related data may include a location of the wind farm, and in this case, the typhoon early warning level determining module 20 may determine the typhoon early warning level according to whether the typhoon related data is acquired, whether a moving path of the typhoon passes through the location of the wind farm and/or a wind circle level of the typhoon at the location of the wind farm. Here, the typhoon early warning level may indicate an influence of the typhoon on the wind farm, and the higher the early warning level of the typhoon, the greater the influence of the typhoon on the wind farm.
By way of example, a typhoon warning level from low to high may include, but is not limited to: no typhoon early warning, typhoon first-level early warning, typhoon second-level early warning, typhoon third-level early warning and typhoon fourth-level early warning. The following describes the determination of the warning level of each typhoon.
The mode for determining no typhoon warning can be as follows: when the typhoon data acquisition module 10 does not acquire the typhoon-related data, it indicates that there is no typhoon, and when there is no typhoon, the typhoon early warning level determination module 20 may determine that the typhoon early warning level is no typhoon early warning.
The mode of determining the typhoon first-level early warning can be as follows: when the moving path of the typhoon does not pass through the position of the wind farm, that is, when the position of the wind farm is outside the range covered by the predetermined wind ring on the moving path of the typhoon, the typhoon early warning level determining module 20 may determine that the typhoon early warning level is typhoon first-level early warning.
The mode of determining the typhoon secondary early warning can be as follows: in one example, when the moving path of the typhoon passes through the position of the wind farm, if the wind circle level of the typhoon at the position of the wind farm is at the first level, that is, when the moving path of the typhoon passes through the position of the wind farm and the position of the wind farm is within the range covered by the wind circle of the first level on the moving path of the typhoon (at this time, the position of the wind farm should be outside the range covered by the wind circle of the second level), the typhoon early warning level determining module 20 may determine that the typhoon early warning level is typhoon secondary early warning. In another example, when the moving path of the typhoon passes through the location where the wind farm is located, if the time that a predetermined wind circle of the at least one wind circle of the typhoon reaches the wind farm is greater than a first set time, the typhoon early warning level determination module 20 may determine that the typhoon early warning level is a typhoon secondary early warning. Here, the predetermined wind circle may refer to any one of the at least one wind circle of the typhoon.
The mode of determining the third-level typhoon warning can be as follows: in one example, when the moving path of the typhoon passes through the position of the wind farm, if the wind circle level of the typhoon at the position of the wind farm is the second level, that is, when the moving path of the typhoon passes through the position of the wind farm and the position of the wind farm is within the range covered by the wind circle of the second level on the moving path of the typhoon (at this time, the position of the wind farm should be out of the range covered by the wind circle of the third level), the typhoon early warning level determining module 20 may determine that the typhoon early warning level is the typhoon third-level early warning. Here, the average wind force of the second level of the windband may be greater than the average wind force of the first level of the windband. In another example, when the moving path of the typhoon passes through the location of the wind farm, if the time that a predetermined wind circle of the at least one wind circle of the typhoon reaches the wind farm is less than a first set time and greater than a second set time, the typhoon early warning level determination module 20 may determine that the typhoon early warning level is a typhoon-level early warning. Here, the time length of the second set time may be greater than the time length of the first set time.
The mode of determining the typhoon four-level early warning can be as follows: in one example, when the moving path of the typhoon passes through the position of the wind farm, if the circle level of the typhoon at the position of the wind farm is the third level, that is, when the moving path of the typhoon passes through the position of the wind farm and the position of the wind farm is within the range covered by the circle of the third level on the moving path of the typhoon, the typhoon early warning level determination module 20 may determine that the typhoon early warning level is the typhoon four-level early warning. Here, the average wind force of the third level of the windband may be greater than the average wind force of the second level of the windband. In another example, when the moving path of the typhoon passes through the position of the wind farm, if the time for a predetermined wind circle of the at least one wind circle of the typhoon to reach the wind farm is less than the second set time and greater than the third set time, the typhoon early warning level determination module 20 may determine that the typhoon early warning level is a typhoon four-level early warning. Here, the time length of the first set time may be greater than the time length of the second set time.

Here, the early warning strategy for typhoons in the wind farm may include a control strategy made for typhoons on wind generating sets in the wind farm and/or an early warning and deployment strategy for operation and maintenance personnel of the wind farm.
For example, early warning policy determination module 30 may determine that both the early warning policy corresponding to the no-typhoon early warning and the early warning policy corresponding to the primary typhoon early warning are to maintain the current operating state of the wind turbine generator in the wind farm.
The early warning strategy determining module 30 may determine that the early warning strategy corresponding to the typhoon secondary early warning may be a first predetermined time before the wind circle of the first level of the typhoon reaches the wind farm, control the wind generating set in the wind farm to perform shutdown self-inspection, and control the wind generating set to resume running after the shutdown self-inspection is completed, and/or display information for instructing an operation and maintenance person of the wind farm to perform manual operation and maintenance on the wind generating set.
The early warning strategy determining module 30 may determine that the early warning strategy corresponding to the typhoon-level early warning may be a second predetermined time before the second-level wind ring of the typhoon reaches the wind farm, control the wind generating set in the wind farm to enter a typhoon control mode, and/or display information related to the typhoon to operation and maintenance personnel of the wind farm.
As an example, the typhoon control mode may refer to controlling the wind turbine generator set to stop and starting the yaw control system, so that the wind turbine generator set is controlled to rotate with the wind direction when the wind circle of the second level of the typhoon reaches the position of the wind farm (or before the wind circle of the second level of the typhoon reaches the position of the wind farm), so as to control the wind turbine generator set to perform self-protection.
The early warning policy determination module 30 may determine that the early warning policy corresponding to the typhoon four-stage early warning may be information for displaying information indicating whether the typhoon center reaches the wind farm and/or information indicating operation and maintenance personnel to perform safety protection.
