TECHNICAL FIELD

[0001] The application belongs to the technical field of power supply and distribution, and particularly relates to a power supply strategy adjustment method and system for a power transmission line based on weather data. BACKGROUND

[0002] When weather data is biased, especially under extreme weather conditions, the power supply stability of the power transmission line is affected to a certain extent. In the prior art, the variation of weather data is often used to determine the optimization scheduling strategy of the power supply, for example, the similar technical solution is given in the invention patent application CN202411756599.1 "Water-wind-solar complementary power generation system optimization scheduling method based on wind-solar prediction". However, the above technical solution has the following technical problems:

[0003] The risk of unexpected events of the power transmission line under different weather conditions is different, and the probability of failure or problem of the power equipment in the power transmission line under the same weather data in different power transmission power intervals is also different. Therefore, how to adjust the power transmission of the power transmission line according to the abnormal conditions of the power equipment in different power transmission power intervals under the weather data and improve the operation reliability of the power transmission line becomes a technical problem to be solved.

[0004] To solve the above technical problems, the application provides a power supply strategy adjustment method and system for a power transmission line based on weather data. SUMMARY

[0005] To achieve the purpose of the application, the application adopts the following technical solutions:

[0006] Specifically, in a first aspect, the application provides a power supply strategy adjustment method for a power transmission line based on weather data, which specifically comprises:

[0007] S1, based on the weather data of the region where the power transmission line is located, determining the failure influence data of different power equipment in different power transmission power intervals, and determining the influence power equipment among the power equipment based on the failure influence data;

[0008] S2, determining the adaptive power interval of the power transmission line according to the failure influence data of different influence power equipment in different power transmission power intervals;

[0009] S3, based on the power transmission plan of the power transmission line, determining the deviation situation of different time periods and the adaptive power interval, and based on the deviation situation, determining that the power transmission deviation risk coefficient of the power transmission line is in the preset risk coefficient interval, and then entering the next step;

[0010] S4 determines different candidate power users in different candidate transmission lines, determines the deviation of the transmission power of the candidate power users in the transmission line according to the deviation of the transmission power of the candidate power users in the different candidate transmission lines and the adaptive power interval, and combines the coincidence data of the deviation of the candidate transmission lines and the transmission line to determine the adjustment strategy of the transmission power of the candidate power users in the transmission line.

[0011] The beneficial effects of the present application are:

[0012] According to the deviation of the transmission power of the transmission line in different time periods and the adaptive power interval, it is determined whether the transmission deviation risk coefficient of the transmission line is within the preset risk coefficient interval, so as to realize the screening of the transmission line with greater deviation from the adaptive power interval from the deviation of the transmission power of the transmission line in different time periods, and lay a foundation for further adjustment of the differentiated transmission power of the transmission line according to the transmission deviation risk coefficient, and improve the reliability and safety of the operation of the transmission line.

[0013] According to the deviation of the transmission power of the candidate power users in different candidate transmission lines and the adaptive power interval, the coincidence data of the deviation of the candidate transmission lines and the transmission line, and the adjustment strategy of the transmission power of the candidate power users in the transmission line, not only the deviation degree of the transmission power of the candidate power users in the candidate transmission line is considered, but also the possibility of transmission power adjustment in the period when the deviation degree of the transmission line does not meet the requirements is considered due to the difference in the coincidence degree of the deviation of the transmission line, which improves the operation reliability of the transmission line on the basis of ensuring the power consumption reliability of the power users.

[0014] Further technical solutions are that the weather data includes temperature, humidity, wind speed and weather type of the area where the transmission line is located.

[0015] Further technical solutions are that the weather type includes precipitation weather, condensation weather, wind and sand weather, lightning weather, sunny day and cloudy day.

[0016] Further technical solutions are that the transmission power interval is divided according to a preset power threshold.

[0017] Further technical solutions are that the fault influence data includes the historical fault times of the power equipment in different transmission power intervals under the weather data.

[0018] Further technical solutions are that the method for determining the affected power equipment in the power equipment is:

[0019] determine the historical failure times in different transmission power intervals according to the historical failure times of the power equipment in different transmission power intervals under the weather data;

[0020] determine the total historical failure times of the power equipment according to the historical failure times in different transmission power intervals;

[0021] determine whether the power equipment is an impact power equipment according to the total historical failure times.

[0022] A further technical solution is that when the total historical failure times are greater than a preset total failure time threshold, it is determined that the power equipment is an impact power equipment.

[0023] A further technical solution is that the method for determining the adjustment strategy of the transmission power of the power transmission line by the alternative power user is:

[0024] determine the power deviation time according to the deviation of the transmission power of the alternative power transmission line of the alternative power user from the adaptive power interval of the alternative power transmission line, and take the time when the adaptive power interval is not in the adaptive power interval as the power deviation time;

[0025] determine the power deviation period of different alternative power transmission lines according to the proportion of the number of power deviation times;

[0026] determine the adjustment strategy of the transmission power of the power transmission line by the alternative power user based on the number of power deviation periods of different alternative power transmission lines and the coincidence of the power deviation period of the alternative power transmission line with the power deviation period of the power transmission line.

[0027] A further technical solution is that the power deviation period is a period in which the proportion of the number of power deviation times is greater than a preset proportion threshold of the number of deviation times.

[0028] A further technical solution is that the adjustment strategy of the transmission power of the power transmission line by the alternative power user is determined based on the number of power deviation periods of different alternative power transmission lines and the coincidence of the power deviation period of the alternative power transmission line with the power deviation period of the power transmission line, and specifically includes:

[0029] determine whether there is an alternative power transmission line whose number of power deviation periods is less than a preset threshold of the number of deviation periods, if yes, perform a preset adjustment processing on the transmission power of the power user, and perform a load processing on the transmission power after the adjustment processing by the alternative power transmission line whose number of power deviation periods is less than the preset threshold of the number of deviation periods, and if no, determine the adjustment strategy of the transmission power of the power transmission line by the alternative power user according to the coincidence of the power deviation period of the alternative power transmission line with the power deviation period of the power transmission line.

[0030] Further technical solutions are as follows: according to the coincidence of the power deviation time period of different alternative power transmission lines and the power deviation time period of the power transmission line, a power transmission adjustment strategy of the alternative power user on the power transmission line is determined, and the strategy specifically includes:

[0031] When there is no alternative power transmission line with the number of coincidences with the power deviation time period of the power transmission line less than the preset coincidence number threshold, the power transmission adjustment of the alternative power user on the power transmission line is not required.

[0032] When there is no alternative power transmission line with the number of coincidences with the power deviation time period of the power transmission line less than the preset coincidence number threshold, the power transmission adjustment of the alternative power user on the power transmission line is not required.

[0033] Further technical solutions are as follows: the second preset mode is to determine an adjustment ratio by using the number of alternative power transmission lines with the number of coincidences with the power deviation time period of the power transmission line less than the preset coincidence number threshold, and to adjust the power transmission of the power user on the power transmission line according to the adjustment ratio and the direction in which the deviation from the adaptive power interval becomes smaller.

[0034] Further technical solutions are as follows: the adjustment ratio is determined according to the number of alternative power transmission lines with the number of coincidences with the power deviation time period of the power transmission line less than the preset coincidence number threshold and a preset corresponding relationship between the adjustment ratio.

[0044] In order for those skilled in the art to better understand the technical solutions in the specification, the technical solutions in the specification will be clearly and completely described below in conjunction with the drawings in the specification. Obviously, the described embodiments are only part of the embodiments of the specification, not all. Based on the embodiments of the specification, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the specification.

[0045] In order to improve the operation reliability of the power transmission line, according to the fault impact situation of different power transmission power intervals of different power devices in the power transmission line under the weather data of the current date, the dynamic adjustment of the transmission power of the power transmission line is realized, the operation reliability of the power transmission line is ensured, and at the same time, different power devices are operated in a stable transmission power interval.

[0046] The impact power device is a power device whose deviation amount of historical fault times in the transmission power interval under a specific weather data is not within a preset deviation amount interval.

[0047] The adaptive power interval is the transmission power interval with the smallest sum of historical fault times of different impact power devices.

[0048] When the number of time instants not in the adaptive power interval is greater than a preset number of time instant threshold, it is determined that the transmission deviation risk coefficient of the power transmission line is within a preset risk coefficient interval.

[0049] When the number of alternative power transmission lines in which the deviation time of the transmission power of the alternative power user from the adaptive power interval is less than the preset deviation time threshold, or the number of coincidences of the deviation time of the alternative power transmission line with the deviation time of the power transmission line is less than the preset coincidence deviation time threshold, the adjustment process of the transmission power of the alternative power user on the power transmission line is performed.

[0050] Embodiment 1

[0051] As Figure 1 shown, the application provides a power transmission line power supply strategy adjustment method based on weather data, specifically comprising:

[0052] S1 determines the fault influence data of different power equipment in different transmission power intervals based on the weather data of the region where the power transmission line is located, and determines the influence power equipment among the power equipment based on the fault influence data.

[0053] Further, the weather data includes temperature, humidity, wind speed and weather type of the region where the power transmission line is located.

[0054] Specifically, the weather type includes precipitation weather, condensation weather, wind and sand weather, lightning weather, sunny day and cloudy day.

[0055] Specifically, the transmission power interval is divided according to a preset power threshold.

[0056] Further, the fault influence data includes the historical fault times of the power equipment in different transmission power intervals under the weather data.

[0057] Specifically, it needs to be explained that, as Figure 2 shown, the method for determining the influence power equipment among the power equipment is:

[0058] determining the historical fault times in different transmission power intervals based on the historical fault times of the power equipment in different transmission power intervals under the weather data;

[0059] determining the total historical fault times of the power equipment based on the historical fault times in different transmission power intervals;

[0060] determining whether the power equipment is an influence power equipment according to the total historical fault times.

[0061] Further, when the total historical fault times are greater than a preset total fault times threshold, the power equipment is determined to be an influence power equipment.

[0062] In another embodiment, the method for determining the influence power equipment among the power equipment is:

[0063] determine the historical failure times of the power equipment in different transmission power intervals under the weather data according to the historical failure times of the power equipment in different transmission power intervals;

[0064] determine the failure time deviation of the power equipment in different transmission power intervals according to the deviation of the historical failure times of the power equipment in different transmission power intervals and the historical failure times of the power equipment under specific weather data;

[0065] determine whether the power equipment is an impact power equipment according to the failure time deviation of the power equipment in different transmission power intervals.

[0066] Further, the specific weather data is a sunny day when the humidity, temperature and wind speed are all within a preset range.

[0067] It should be noted that when the power equipment has a transmission power interval with a failure time deviation greater than a preset failure time deviation threshold, the power equipment is determined to be an impact power equipment.

[0068] S2 determines the adaptive power interval of the power transmission line according to the failure impact data of different impact power equipment in different transmission power intervals;

[0069] Further, when there is a transmission power interval with a weather impact coefficient greater than a preset weather impact coefficient threshold, the power equipment is determined to be an impact power equipment.

[0070] Specifically, as shown in Figure 3 The method for determining the adaptive power interval of the power transmission line is:

[0071] determine the historical failure times of different impact power equipment in different transmission power intervals under the weather data according to the failure impact data of different impact power equipment in different transmission power intervals;

[0072] determine the failure time deviation of different transmission power intervals according to the historical failure times in different transmission power intervals and the deviation of the historical failure times of the power equipment in different transmission power intervals under specific weather data, and determine the failure time deviation of different transmission power intervals;

[0073] determine whether the transmission power interval is an adaptive power interval according to the failure time deviation of different power equipment in the transmission power interval.

[0074] Further, determine whether the transmission power interval is an adaptive power interval according to the failure time deviation of different power equipment in the transmission power interval, specifically including:

[0075] The adaptive power interval is the power transmission interval with the minimum average of the fault number deviation of different power equipments.

[0076] In another embodiment, the method for determining the adaptive power interval of the power transmission line is:

[0077] The historical fault number of the different power equipments in the different power transmission intervals under the weather data is determined according to the fault influence data of the different power equipments in the different power transmission intervals.

[0078] The fault number deviation of the different power transmission intervals is determined according to the historical fault number in the different power transmission intervals and the deviation of the historical fault number of the power equipments under the specific weather data, and the fault number deviation of the different power transmission intervals is determined.

[0079] The power equipments with the fault number deviation greater than the preset deviation value are determined according to the fault number deviation of the different power equipments in the power transmission interval, and the power equipments are taken as the deviation power equipments, and whether the power transmission interval is the adaptive power interval is determined according to the number of the deviation power equipments.

[0080] Further, the adaptive power interval is the power transmission interval with the minimum number of the deviation power equipments.

[0081] It can be understood that the adaptive power interval is the power transmission interval with the minimum average of the fault abnormality coefficient of the different power equipments.

[0082] S3, based on the power transmission plan of the power transmission line, determines the deviation condition of the different time periods from the adaptive power interval, and when the transmission deviation risk coefficient of the power transmission line is in the preset risk coefficient interval based on the deviation condition, enters the next step.

[0083] Specifically, the power transmission plan is determined according to the load scheduling plan of the power transmission line.

[0084] Specifically, as shown in Figure 4 The method for determining the transmission deviation risk coefficient of the power transmission line is:

[0085] The power transmission plan of the power transmission line in the different time periods is determined according to the deviation condition of the different time periods from the adaptive power interval, and the time point when the power transmission plan is not in the adaptive power interval is taken as the power deviation time point;

[0086] The deviation time point proportion of the different time periods is determined according to the proportion of the number of the power deviation time points in the different time periods.

[0087] Determine the transmission deviation risk coefficient of the power transmission line based on the average value of the proportion of the deviation time in different time periods.

[0088] Further, the transmission deviation risk coefficient of the power transmission line ranges from 0 to 1. When the transmission deviation risk coefficient of the power transmission line is not within the preset risk coefficient interval, it is further determined whether the transmission deviation risk coefficient of the power transmission line is greater than a preset risk coefficient threshold. If yes, the power users in the power transmission line that have alternative power transmission lines are all subjected to preset mode of transmission power adjustment processing. If no, the power users in the power transmission line are temporarily not subjected to transmission power adjustment processing.

[0089] It can be understood that the preset mode is to adjust the transmission power of different power users in the power transmission line in different directions according to the deviation of the transmission power from the adaptive power interval.

[0090] S4 takes the power users in the power transmission line as alternative power users, determines the deviation of the transmission power of different alternative power users in different alternative power transmission lines from the adaptive power interval, and determines the adjustment strategy of the transmission power of the alternative power users in the power transmission line in combination with the coincidence data of the deviation of the alternative power transmission lines and the power transmission line.

[0091] Further, the alternative power transmission line is a power transmission line that can transmit power to the alternative power user except the power transmission line.

[0092] Specifically, the method for determining the adjustment strategy of the transmission power of the alternative power users in the power transmission line is as follows:

[0093] Determine the power deviation time according to the deviation of the transmission power of the alternative power users in different alternative power transmission lines from the adaptive power interval of the alternative power transmission line, and take the time when different time periods are not in the adaptive power interval as the power deviation time;

[0094] Determine the power deviation time period of different alternative power transmission lines according to the proportion of the number of the power deviation time;

[0095] Determine the adjustment strategy of the transmission power of the alternative power users in the power transmission line based on the number of the power deviation time period of different alternative power transmission lines and the coincidence of the power deviation time period and the power deviation time period of the power transmission line.

[0096] Further, the power deviation time period is a time period in which the proportion of the number of the power deviation time is greater than a preset proportion threshold of the number of the power deviation time.

[0097] It should be noted that the adjustment strategy of the power transmission of the alternative power user in the power transmission line is determined according to the number of power deviation periods of different alternative power transmission lines and the coincidence of the power deviation periods of the power transmission line, and specifically comprises:

[0098] If there is an alternative power transmission line with a number of power deviation periods less than the preset deviation period threshold, the power transmission of the power user is adjusted in a preset manner, and the power transmission of the power user after the adjustment is carried out by the alternative power transmission line with the number of power deviation periods less than the preset deviation period threshold is carried out; otherwise, the adjustment strategy of the power transmission of the alternative power user in the power transmission line is determined according to the coincidence of the power deviation periods of different alternative power transmission lines and the power deviation periods of the power transmission line.

[0099] Further, the adjustment strategy of the power transmission of the alternative power user in the power transmission line is determined according to the number of power deviation periods of different alternative power transmission lines and the coincidence of the power deviation periods of the power transmission line, and specifically comprises:

[0100] When there is an alternative power transmission line with a number of coincidences with the power deviation periods of the power transmission line less than a preset coincidence number threshold, the power transmission of the power user is adjusted in a second preset manner, and the power transmission of the power user after the adjustment is carried out by the alternative power transmission line with the number of coincidences with the power deviation periods of the power transmission line less than the preset coincidence number threshold is carried out;

[0101] When there is no alternative power transmission line with a number of coincidences with the power deviation periods of the power transmission line less than a preset coincidence number threshold, the adjustment of the power transmission of the alternative power user in the power transmission line is not necessary.

[0102] It can be understood that the second preset manner is to determine an adjustment ratio by using the number of alternative power transmission lines with a number of coincidences with the power deviation periods of the power transmission line less than a preset coincidence number threshold, and to adjust the power transmission of the power user in the power transmission line according to the adjustment ratio and the direction in which the deviation from the adaptive power interval becomes smaller.

[0103] It should be noted that the adjustment ratio is determined according to the number of alternative power transmission lines with a number of coincidences with the power deviation periods of the power transmission line less than a preset coincidence number threshold and a preset corresponding relationship between the adjustment ratio.
