[0026] See also Figure 1 The embodiment of the present invention provides a safety management method for a wind farm under typhoon conditions, the method comprising:

[0027] S10) obtaining disaster-causing information of wind power equipment under typhoon conditions;

[0028] S20) determining response information corresponding to the disaster information;

[0029] S30) determining a typhoon to be evaluated, performing a destructive force analysis on the typhoon to be evaluated, and generating corresponding destructive force analysis information;

[0030] S40) acquiring disaster assessment information corresponding to the destructive force analysis information from the disaster information;

[0031] S50) Analyze the disaster assessment information based on the response information to generate corresponding safety management results.

[0032] In a possible implementation, disaster-causing information of wind power equipment under typhoon conditions is first obtained. In an embodiment of the present invention, obtaining disaster-causing information of wind power equipment under typhoon conditions includes: obtaining historical fault data of the wind power equipment; determining the fault category of the wind power equipment based on the historical fault data; performing clustering operations on the fault categories to obtain clustered categories; and determining the disaster-causing information of the wind power equipment under typhoon conditions based on the clustered categories.

[0033] Specifically, the historical fault data of the wind power equipment is first obtained, and then the fault type of the wind power equipment is determined based on the historical fault data. For example, in one embodiment, when a tropical cyclone vortex passes, the wind direction changes rapidly in a short period of time, and the center of the typhoon even undergoes a sudden change of 120° to 180°. The yaw system of the wind turbine cannot keep up with the rapid change of wind direction, resulting in a change from facing the wind directly to facing the wind sideways, and the wind receiving area of ​​the entire wind turbine also changes accordingly. Usually, the wind pressure generated by the wind blowing from the side is more than 30% greater than the wind pressure of the wind coming from the front. At the same time, the side wind and turbulence make the blades most unfavorable, which in turn causes damage to the wind turbine. For this kind of fault data, it can be determined that the fault type is a failure of yaw to the wind.

[0034] For example, after analyzing a large amount of historical fault data, a corresponding fault category is assigned to each historical fault data, and then a clustering operation is performed on all fault categories. For example, a common clustering algorithm (such as K-Means clustering algorithm, etc.) can be used to cluster the above fault categories and obtain clustered categories. For example, in this embodiment, wind yaw failure is used as a clustered category. Among the fault types, damage to the yaw system, especially damage to wind direction observation instruments caused by strong winds, and other accidents can also be included. In an embodiment of the present invention, the clustered categories of wind power equipment determined based on historical fault data include but are not limited to: wind yaw failure, unit fatigue and vibration, tropical cyclone updraft-induced failures, and power outages. At this time, the disaster information of wind power equipment under typhoon conditions is determined based on the above clustered categories. At this time, the response information corresponding to the disaster information is further determined.

[0035] See also Figure 2In an embodiment of the present invention, the determining of the response information corresponding to the disaster information includes:

[0036] S21) sequentially acquiring characteristic information of each clustered category, wherein the characteristic information includes wind speed information, destructive force index information, and eyewall information;

[0037] S22) determining the disaster-causing degree information of each clustered category to the wind power equipment;

[0038] S23) establishing a correlation mapping between the characteristic information and the disaster degree information;

[0039] S24) determining response information for information of different disaster severity levels;

[0040] S25) Determine response information corresponding to the disaster information based on the association mapping.

[0041] In a possible implementation, since the main response measures are all specified for typhoons, when generating response information, its core is determined based on the disaster situation of the typhoon. For example, in this embodiment, the characteristic information of each clustered category is first obtained in turn, and the characteristic information includes but is not limited to wind speed information, destructive index information, and eyewall information. Then determine the disaster degree information of each clustered category to the wind power equipment. For example, the technician can evaluate the disaster situation corresponding to each clustered category on the wind power equipment based on historical fault data and the corresponding equipment damage, and generate the corresponding disaster degree information. At this time, establish an association mapping between the above-mentioned characteristic information and the disaster program information. For example, in this embodiment, the disaster degree is divided into 4 levels (for example, primary, intermediate, advanced, and special). It should be noted that the technician can divide it into more or fewer levels according to actual needs, which is not limited here.

[0042] For example, when the characteristic information of a typhoon meets the following conditions, the disaster degree is determined to be primary: level 7 ≤ V < V1, and the destructive index ≤ 2, and it is not within the eye wall range, where V is the wind speed of the typhoon and V1 is the cut-out wind speed of the typhoon. Specifically, the correlation mapping between the characteristic information of the typhoon and the disaster degree can be shown in Table 1:

[0043] Disaster severity Feature information primary Level 7 ≤ V < V1, and the destructive index ≤ 2, and not within the eye wall intermediate V1≤V<V2, and the destructive index ≤2, and it is not within the eyewall range advanced V2≤V<V3, and 2≤destructive index≤3, and not within the eyewall range Special V3<V, or destructive index = 4, or within the eyewall

[0044] Table 1

[0045] Among them, V2 is the maximum wind speed that the wind power equipment is intended to apply, and V3 is the design limit wind speed of the wind power equipment. At this time, the response information for different disaster severity information is further determined. For example, in this embodiment, corresponding to the above 4 disaster severity levels, 4 corresponding response measures are adopted, specifically normal power generation, power generation monitoring, cut-out defense, and disaster defense. The implementation content of each response measure can be:

[0046] Normal power generation: No special treatment is required and normal power generation can be achieved. The general corresponding condition is that the wind speed is less than the cut-out wind speed of the unit.

[0047] Power generation monitoring: The wind turbine operating status needs to be closely monitored to decide whether to switch to the cut-out defense state, storm power generation state, or maintain normal power generation state. Generally, the corresponding conditions are that the typhoon is approaching and the wind speed reaches the cut-out wind speed.

[0048] Cut-out defense: The wind turbine stops generating electricity, changes the pitch to the feathering state, and the yaw system continues to work, keeping the wind turbine facing the main wind direction, so that the wind turbine maintains the best posture with minimum wind pressure. This measure is generally used when the wind farm is in the strong wind area outside the strong typhoon, and the corresponding conditions are that the wind speed exceeds the cut-out wind speed and the wind direction does not change much.

[0049] Disaster prevention: The wind turbine stops generating electricity and changes its pitch to the feathering state. If there is a risk of power outage, consider long-distance yaw in advance to face the possible main wind direction. This measure is used when the wind farm is in the typhoon vortex area, and the corresponding conditions are that the wind speed may exceed the design limit wind speed or the wind speed and wind direction change rapidly.

[0050] At this time, according to the above-mentioned association mapping, the response information corresponding to the disaster information can be determined, that is, response measures are established under different typhoon disaster situations. At this time, the wind power equipment can be safely managed under any typhoon conditions. For example, at a certain time, the company obtains forecast information for the typhoon, determines the typhoon to be evaluated based on the forecast information, and then conducts a destructive force analysis on the typhoon to be evaluated, and generates corresponding destructive force analysis information.

[0051] See also Figure 3 In an embodiment of the present invention, the step of performing a destructive force analysis on the typhoon to be assessed and generating corresponding destructive force analysis information includes:

[0052] S31) obtaining a preset typhoon analysis model;

[0053] S32) performing a structural analysis on the typhoon to be evaluated based on the preset typhoon analysis model to obtain structural analysis information, wherein the structural analysis information includes wind speed information, wind direction information, and eyewall information;

[0054] S33) Generate corresponding destructive force analysis information based on the structural analysis information.

[0055] In a possible implementation, after determining the typhoon to be evaluated, a preset typhoon analysis model is first obtained. For example, the preset typhoon analysis model is a typhoon analysis model designed or created in advance by a technician. According to the typhoon analysis model, the destructive power analysis information and other data of the typhoon can be calculated through typhoon forecast data or typhoon observation data. Specifically, the structure of the typhoon to be evaluated is analyzed through the typhoon analysis model, and the corresponding structural analysis information is obtained. The structural analysis information includes but is not limited to wind speed information, wind direction information, eyewall information and other information of the typhoon to be evaluated. At this time, the destructive power analysis information of the typhoon to be evaluated is calculated based on the above-mentioned structural analysis information, such as a specific destructive power assessment value.

[0056] At this time, the corresponding disaster assessment information is obtained from the disaster information based on the destructive force analysis information. For example, the destructive force assessment value is matched with the disaster degree information, and the disaster degree of the typhoon to the wind power equipment is determined, and the disaster degree is used as the disaster assessment information. At this time, the response information that the wind power equipment needs to adopt for the typhoon to be evaluated is further determined from the above-mentioned response information based on the above-mentioned association mapping relationship.

[0057] In an embodiment of the present invention, the disaster assessment information is analyzed based on the response information to generate a corresponding safety management result, including: obtaining the impact time of the typhoon to be assessed on the wind power equipment; determining the corresponding safety management stage based on the impact time; and analyzing the disaster assessment information based on the safety management stage and the response information to generate a corresponding safety management result.

[0058] Specifically, in a possible implementation, in order to achieve the maximum protection effect on wind power equipment, different corresponding safety protection measures are taken according to the different impact stages of the typhoon to be assessed on the wind power equipment. Therefore, after determining the disaster assessment information, the impact time of the typhoon to be assessed on the wind power equipment is first obtained. For example, the impact time of the typhoon passing through the wind power equipment is determined according to the above typhoon forecast information. In this embodiment, according to different impact times, it is divided into 6 different safety protection stages: 48 hours before the maximum impact of the tropical cyclone (stage one), 24 to 48 hours after the maximum impact of the tropical cyclone (stage two), the maximum impact of the tropical cyclone occurs within 24 hours (stage three), during the maximum impact of the tropical cyclone or within 6 hours (stage four), the maximum impact of the tropical cyclone has passed, and the wind speed continues to be less than the cut-out wind speed (stage five), and the maximum impact of the tropical cyclone has passed, and the wind speed continues to be less than 10m / s (stage six).

[0059] At this time, the disaster assessment information is analyzed based on the above different security management stages and response information, and corresponding security management results are generated. Specifically, in this embodiment, examples of security management measures adopted in the above six different security management stages are as follows:

[0060] Phase 1: Before a tropical cyclone strikes, conduct the following checks:

[0061] ① The impeller of the non-generator set is in a locked state, and the high-speed brake of the unit is in a released state;

[0062] ② Carry out random inspection on the yaw condition of the unit, with the inspection ratio being 15%, to ensure that the yaw function of the unit is normal;

[0063] ③ Based on the monthly and daily inspection reports of the crew, it is 100% confirmed that the front and rear covers of the crew cabin are in the closed state.

[0064] Phase 2: Typhoon response preparation phase, the following measures need to be taken:

[0065] ① Personnel not involved in emergency situations are prohibited from going out for work;

[0066] ② Rapidly check and confirm the status of the unit to ensure normal communication, normal operation, and normal maximum wind speed observation;

[0067] ③Remotely monitor the fan and provide timely feedback when any abnormality occurs.

[0068] Phase 3: If the wind farm operating condition index is "normal power generation" or "power generation monitoring", the response measures are the same as those in Phase 2;

[0069] If the wind farm is in the "cut-out defense" condition, in addition to the measures taken in stage 2, the following measures need to be added:

[0070] ①After reaching the cut-out wind speed, manually stop the unit and monitor the unit to maintain the yaw state facing the wind

[0071] If the wind farm is in the "disaster prevention" condition, the following measures need to be added:

[0072] ② Manually shut down the unit in advance

[0073] ③ If power outage is required, remotely yaw the wind turbine in advance to face the possible main wind direction.

[0074] Stage 4: The stage of maximum impact of tropical cyclones, the following measures need to be taken:

[0075] ① Personnel are strictly prohibited from working outside;

[0076] ②Remotely monitor the wind turbine’s feathering status and wind-facing status;

[0077] ③ If a power outage occurs, promptly yaw the remaining power units to the main wind direction as a precaution.

[0078] Phase 5: Recovery after a tropical cyclone. The strategies are as follows:

[0079] ① For wind farms in the "power generation", "power generation monitoring" and "cut-out defense" working conditions, the wind turbines can be started after the communicating units are normal.

[0080] ② For wind turbines that are experiencing "disaster defense" conditions, they cannot be started remotely directly. They must be started after manual inspection.

[0081] Phase 6: Restoration to normal after the tropical cyclone. The strategy is as follows:

[0082] ① Personnel can go out for inspection and maintenance as usual

[0083] ② Check the operation of the unit and line

[0084] ③ Check the appearance of the wind vane, blades and fan of the unit

[0085] ④ After experiencing the "disaster prevention" condition, the wind turbine can be restarted after manual inspection.

[0086] This enables safe management of wind power equipment under any typhoon conditions, effectively ensures the company's production and operation safety, and improves safety.

[0087] In an embodiment of the present invention, by utilizing refined meteorological forecast data, combining the impact characteristics of typhoons on power generation equipment with the actual protective measures of the enterprise, accurately determining the safety protection measures for different typhoon impact situations, and establishing an accurate prediction model of the typhoon operating condition index for wind power equipment operation, the enterprise is provided with reliable and effective typhoon operating condition warnings and defense measures recommendations before, during and after the typhoon impact, effectively ensuring the safe operation of wind turbines and meeting actual needs.

[0088] Furthermore, based on this, enterprises can make full use of the wind resources brought by tropical cyclones while ensuring the safety of wind farms to the greatest extent, thereby increasing the power generation income of wind farms and improving the operating efficiency of enterprises.
