Detailed ways

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 early warning method for a wind farm according to an exemplary embodiment of the present invention.

Referring to FIG. 1 , in step S10 , typhoon-related data is acquired.

As an example, the typhoon-related data may include but not limited to at least one of the following items: typhoon movement path, typhoon wind speed, typhoon wind direction, gust information, rainfall, lightning information, information about at least one wind circle of the typhoon, The arrival time of the at least one wind circle at the wind farm.

In a preferred example, the typhoon-related data can be obtained from a typhoon data source outside the wind farm through the reverse isolation device, for example, the typhoon-related data can be obtained from the typhoon data source outside the wind farm through the Internet through the reverse isolation device. Here, the typhoon data source may be a typhoon-related data provider, which can obtain and provide typhoon-related data from relevant meteorological units or Internet platforms.

Preferably, the steps of determining the typhoon warning level of the wind farm and determining the typhoon warning strategy of the wind farm can be performed inside the wind farm, that is, the steps of determining the typhoon warning level of the wind farm and determining the typhoon warning strategy of the wind farm are performed based on the local area network inside the wind farm. steps in an early warning strategy. Here, the reverse isolation device, as a device inside the wind farm, can be used to realize the physical isolation between the inside and outside of the wind farm. vent.

In step S20, the 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 SCADA (supervisory control and data acquisition, monitoring and data acquisition) system can be arranged in a wind farm, and the SCADA system can perform data acquisition and control commands for the wind turbines in the wind farm, and can be used on its monitoring platform Display the operating status of wind turbines and typhoon-related data for staff monitoring. In this case, the location of the wind farm can be obtained from the SCADA system.

The typhoon early warning method for a wind farm according to an exemplary embodiment of the present invention can analyze and process the typhoon-related data obtained from a typhoon data source outside the wind farm and the wind farm-related data obtained from the SCADA system of the wind farm to determine the Typhoon early warning strategy. As a non-limiting example, the typhoon warning method for a wind farm according to an exemplary embodiment of the present invention may be implemented in a SCADA system of a wind farm.

Preferably, the wind farm-related data may include the location of the wind farm. In this case, the step of determining the typhoon warning level of the wind farm based on the wind farm-related data and the acquired typhoon-related data may include: The typhoon warning level is determined based on the data, whether the moving path of the typhoon passes through the location of the wind farm and/or the wind circle level of the typhoon at the location of the wind farm. Here, the typhoon warning level may indicate the impact of the typhoon on the wind farm, and the higher the typhoon warning level, the greater the impact of the typhoon on the wind farm.

As an example, the typhoon warning levels from low to high may include but not limited to: no typhoon warning, typhoon level 1 warning, typhoon level 2 warning, typhoon level 3 warning, and typhoon level 4 warning. The following is an introduction to the determination method of each typhoon warning level.

For example, the manner of determining no typhoon warning may be: when no typhoon-related data is obtained, it may indicate that there is no typhoon; when there is no typhoon, the typhoon warning level may be determined as no typhoon warning.

The way to determine the first-level warning of typhoon can be: when the moving path of the typhoon does not pass through the location of the wind farm, that is, when the location of the wind farm is outside the range covered by the set wind circle on the moving path of the typhoon, it can be determined The typhoon warning level is typhoon level 1 warning. As an example, the set wind circle may refer to the wind circle of the first level (ie, the wind circle with the lowest average wind force in the typhoon), but the present invention is not limited thereto, and may also refer to wind circles of other levels. For example, when the location of the wind farm is not within the range covered by the first-level wind circle in the movement path of the typhoon, the typhoon warning level can be determined as the first-level typhoon warning.

The way to determine the typhoon's second-level early warning can be: in one example, when the moving path of the typhoon passes the location of the wind farm, if the wind circle level of the typhoon at the location of the wind farm is the first level, that is, when the typhoon's The movement path passes through the location of the wind farm, and the location of the wind farm is within the range covered by the first-level wind circle on the movement path of the typhoon (at this time, the location of the wind farm should also be within the coverage of the second-level wind circle outside the scope), the typhoon warning level is determined as typhoon level two. In another example, when the moving path of the typhoon passes the location of the wind farm, if the predetermined wind circle in the at least one wind circle of the typhoon arrives at the wind farm at a time greater than the first set time, the typhoon warning level may be determined It is a typhoon level two warning. Here, the predetermined wind circle may refer to any one of the at least one wind circle of the typhoon.

The way to determine the typhoon three-level early warning can be: in one example, when the moving path of the typhoon passes the location of the wind farm, if the wind circle level of the typhoon at the location of the wind farm is the second level, that is, when the typhoon The movement path of the typhoon passes through the location of the wind farm, and the location of the wind farm is within the range covered by the second-level wind circle on the movement path of the typhoon (at this time, the location of the wind farm should also be covered by the third-level wind circle outside the range), the typhoon warning level is determined as typhoon three-level warning. Here, the average wind force of the wind circle of the second level may be greater than the average wind force of the wind circle of the first level. In another example, when the moving path of the typhoon passes the location of the wind farm, if the predetermined wind circle in the at least one wind circle of the typhoon arrives at the wind farm at a time shorter than the first set time and greater than the second set time, Then the typhoon warning level can be determined as typhoon three-level warning. Here, the time length of the second set time may be greater than the time length of the first set time.

The way to determine the typhoon four-level early warning can be: in one example, when the moving path of the typhoon passes the location of the wind farm, if the wind circle level of the typhoon at the location of the wind farm is the third level, that is, when the typhoon When the movement path of the typhoon passes the location of the wind farm, and the location of the wind farm is within the range covered by the third-level wind circle on the movement path of the typhoon, the typhoon warning level can be determined as a typhoon level-4 warning. Here, the average wind force of the wind circle of the third level may be greater than the average wind force of the wind circle of the second level. In another example, when the moving path of the typhoon passes the location of the wind farm, if the predetermined wind circle in the at least one wind circle of the typhoon arrives at the wind farm, the time is less than the second set time and greater than the third set time time, the typhoon warning level can be determined as typhoon level 4 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 the division of typhoon warning levels into five levels in the exemplary embodiment of the present invention is only an example, and those skilled in the art can adjust the classification of typhoon warning levels in combination with the actual operation conditions of the wind farm and the needs of the owners, and also The naming of typhoon warning levels can be modified. In addition, those skilled in the art can also adjust the early warning strategy corresponding to each typhoon early warning level, so that it can not only maximize the power generation time of the wind power generating set, but also ensure the safe operation of the wind power generating set.

In step S30, a typhoon warning strategy for the wind farm is determined according to the determined typhoon warning level of the wind farm. Preferably, different typhoon warning levels may correspond to different warning strategies. But the present invention is not limited thereto, and the same early warning strategy can also be used for two different typhoon warning levels. Here, the typhoon early warning strategy of the wind farm may include a typhoon control strategy for the wind power generators in the wind farm and/or an early warning and deployment strategy for the operation and maintenance personnel of the wind farm.

For example, the early warning strategy corresponding to no typhoon early warning and the early warning strategy corresponding to the first level typhoon early warning may be to maintain the current operating state of the wind power generators in the wind farm.

The early warning strategy corresponding to the typhoon’s second-level early warning can be to control the wind turbines in the wind farm to perform shutdown self-inspection at the first predetermined moment before the typhoon’s first-level wind circle reaches the wind farm, and when the shutdown self-inspection is completed Then control the wind power generating set to resume operation, and/or display information for instructing manual operation and maintenance of the wind power generating set to the operation and maintenance personnel of the wind farm.

It should be understood that when it is predicted that the wind circle of the first level of the typhoon will pass the location of the wind farm, there is still a long time before the wind circle of the first level reaches the location of the wind farm. As an example, the first predetermined moment The corresponding time length can be more than ten hours, dozens of hours, several days or even longer, so that the wind farm has sufficient preparation time. At this time, the wind generating set can be controlled to perform a self-check to ensure the safety of the wind generating set when a typhoon comes. Optionally, the operation and maintenance personnel can also be prompted to enter the emergency response process (that is, the operation and maintenance personnel are prompted to arrive at their respective positions to enter the preparation state for the arrival of the typhoon), and problems can be detected during the self-inspection process of controlling the wind turbine , prompt the operation and maintenance personnel in charge of the wind power generation unit in charge of the problem to deal with it in time.

As an example, the self-inspection of the wind power generating set may include but not limited to detecting the status and fault information of each component of the wind generating Whether the self-test is completed) is stored.

As an example, the self-test of the wind power generating set may include but not limited to at least one of the following items: pitch emergency feathering function test, pitch lock pin locking function test, yaw brake mechanism function test, yaw drive mechanism Functional test, yaw twisted cable angle monitoring, anemometer wind vane fault status, communication detection.

The early warning strategy corresponding to the typhoon three-level early warning can be to control the wind power generators in the wind farm to enter the typhoon control mode at the second predetermined moment before the second-level wind circle of the typhoon arrives at the wind farm, and/or to send wind power to the wind farm. The operation and maintenance personnel of the display the information related to the typhoon.

Preferably, the time length corresponding to the second predetermined moment can be shorter than the time length corresponding to the first predetermined moment, generally the time length corresponding to the second predetermined moment can be several hours, at this time, the wind power generators in the wind farm can be controlled to enter the typhoon control mode, and/or display typhoon-related information to the operation and maintenance personnel of the wind farm. Here, it should be understood that those skilled in the art can adjust the time lengths corresponding to the first predetermined moment and the second predetermined moment according to the requirements of the wind farm and the owner.

As an example, the typhoon control mode may refer to controlling the shutdown of the wind turbine and starting the yaw control system so that when the second-level wind circle of the typhoon reaches the position of the wind farm (it may also be the second-level wind circle of the typhoon reaches the wind farm Before the site is located) to control the wind turbine to rotate with the wind direction, so as to control the wind turbine for self-protection.

The early warning strategy corresponding to the typhoon four-level early warning may be displaying information indicating whether the typhoon center has reached the wind farm and/or instructing operation and maintenance personnel to take safety protection.

At this time, the center of the typhoon is about to reach the location of the wind farm. At this time, the operation and maintenance personnel should be reminded to prepare for safety protection, such as reminding the operation and maintenance personnel to stay in the safe area and not to go outside, and the movement path of the typhoon can also be displayed in real time and the status of the wind turbines in the wind farm.

Preferably, the typhoon warning method for a wind farm according to an exemplary embodiment of the present invention may further include displaying The real situation of the typhoon and/or the operation status of the wind turbines in the wind farm based on the early warning strategy.

In this example, an offshore wind farm is taken as an example for introduction, but the present invention is not limited thereto, and the above typhoon warning method for a wind farm is also applicable to an onshore or coastal wind farm.

As shown in Figure 2, assuming that a typhoon has been formed at point O from the typhoon data source, and the moving path of the typhoon is Y, the typhoon includes three wind circles, which are the first-level wind circle 1 and the second-level wind circle Circle 2 and wind circle 3 for the third grade. Here, the average wind force of the wind circle 1 of the first level is less than the average wind force of the wind circle 2 of the second level, and the average wind force of the wind circle 2 of the second level is less than the average wind force of the wind circle 3 of the third level, and the wind circle of the first level The area covered by the wind ring 1 is larger than the area covered by the wind ring 2 of the second level, and the area covered by the wind ring 2 of the second level is larger than the area covered by the wind ring 3 of the third level.

Points A, B, C, and D are selected points on the boundary of the wind farm. The area enclosed by connecting the above points in turn is the location of the wind farm. In an exemplary embodiment of the present invention, it can be based on Whether there is a typhoon, whether the moving path of the typhoon passes through the location of the wind farm and/or the level of the wind circle of the typhoon at the location of the wind farm determines the typhoon warning level, and further determines the warning strategy corresponding to the typhoon warning level.

For example, the wind resource data may refer to the average wind speed in the first predetermined time period and the average wind direction in the second predetermined time period. Here, the time lengths of the first predetermined time period and the second predetermined time period may be the same or different.

The operating data of the wind turbines in the wind farm may include, but not limited to, at least one of the following: information indicating the operating status of the wind turbines, information indicating whether a self-test for the wind turbines is complete, grid voltage, variable Propeller pitch angle, instantaneous value of generator speed, yaw angle value, rotation speed of wind turbine under yaw control, pressure value of yaw control system, brake status of yaw control system, fault type.

The typhoon data source obtains typhoon-related data. Here, the reverse isolation device, as a device inside the wind farm, can be used to realize the physical isolation between the inside and outside of the wind farm. vent.
