[0053] The embodiment of the present invention provides an operation alarm method and device for an electric power system, which is used to solve the technical problem that the operation alarm scheme of the existing electric power system cannot achieve efficient protection and early warning in areas prone to lightning because it needs to obtain the operation status of electric power equipment one by one for data processing.

[0054] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] See also Figure 1 , Figure 1 A flowchart of the steps of an operation alarm method of an electric power system provided in Embodiment 1 of the present invention.

[0056] The present invention provides an operation alarm method for a power system, which is used in a power system. The power system includes power equipment at multiple levels and a lightning monitor. The method includes:

[0057] Step 101, when any lightning monitor collects ion information, the operating status information of each power device is obtained in real time;

[0058] Operation status information refers to the information displayed on each power device or the monitoring device connected thereto, which usually includes normal or abnormal information.

[0059] In an embodiment of the present application, in order to realize subsequent real-time alarm and adjustment of power equipment, the operating status information corresponding to the power equipment at each level in the power system can be obtained in real time through this device as a data basis.

[0060] Step 102, calculating the normalized ratio of the operation status information according to the divided areas where the power equipment is located, and obtaining the system operation status information of the power system in each divided area;

[0061] The normalized ratio refers to calculating the ratio of the normal number to the total number based on the normal number and abnormal number of the operating status information after counting the operating status information of each power device.

[0062] In a specific implementation, the various power devices in the power system are usually placed in different divided areas and there are many of them. In order to save subsequent computing resources, the divided areas where the power devices are located can be used as computing units, and the normalized ratio of the operating status information can be calculated separately to obtain the system operating status information of the power system in each divided area.

[0063] For example, there are multiple divided areas under the thunderstorm weather at the current time point, and there are 10 power equipment in each divided area. Among them, 4 power equipment are operating abnormally due to the thunderstorm weather, and 6 power equipment are operating normally. At this time, the normalized ratio corresponding to the operating status information of the divided area is calculated to be 0.6.

[0064] Step 103, calculating the ratio of each system operation status information to the preset conventional system operation status information, and obtaining the operation status impact degree corresponding to each divided area;

[0065] The conventional system operation status information refers to the system operation status information corresponding to each divided area under conventional weather conditions such as sunny, light rain, cloudy, or the most common weather on the current date in the past decades.

[0066] In the embodiment of the present application, the regions can be divided into dimensions, and the ratios between the corresponding system operation status information and the conventional system operation status information are calculated respectively, so as to obtain the operation status impact degree corresponding to each divided region.

[0067] It should be noted that the numerical range of the operating status impact degree is 0-2. When the value is equal to or greater than 1, it represents a positive impact, indicating that under the influence of thunder and lightning weather, the operation of the power equipment in the divided area is not affected and can even operate more efficiently; when the value is less than 1, it represents a negative impact, and at this time, it is necessary to take alarm protection measures for the power equipment in the divided area; if the value is greater than or equal to 2, it indicates that there is damaged power equipment in the divided area, and the operation and maintenance personnel can be notified to perform further power outages or repairs.

[0068] Step 104, determining the current lightning activity probability corresponding to each divided area based on the ion information and the historical lightning activity probability;

[0069] Optionally, step 104 may include the following sub-steps:

[0070] Obtain the ion intensity corresponding to the ion information;

[0071] According to the ion intensity, a preset ion intensity-probability relationship table is retrieved to obtain the probability of detecting lightning activities corresponding to each divided area centered on the lightning monitor;

[0072] The probabilities and values ​​of each detected lightning activity probability and the historical lightning activity probability are calculated respectively to obtain the current lightning activity probability corresponding to each divided area.

[0073] While calculating the impact degree of the operating status corresponding to each divided area, the lightning monitor can obtain the ion intensity corresponding to the ion information and the historical lightning activity probability at the current moment in the past few years. According to the ion intensity, the preset ion intensity-probability relationship table is retrieved to determine the probability of lightning activity detection corresponding to the ion intensity, and the corresponding lightning activity detection probability is determined by dividing the area one by one with the lightning monitor as the center.

[0074] Furthermore, the probabilities and values ​​of each detected lightning activity probability and the historical lightning activity probability are calculated respectively to obtain the current lightning activity probability corresponding to each divided area.

[0075] It should be noted that the probability of historical lightning activity can obtain the number of historical lightning activities and the number of statistical years in each divided area. By calculating the ratio of the number of historical lightning activities to the number of years, the probability of historical lightning activity can be obtained.

[0076] Step 105: Generate protection alarm information corresponding to each divided area according to the current lightning activity probability and the impact degree of the operating status.

[0077] Optionally, step 105 may include the following sub-steps:

[0078] According to the probability range corresponding to each current lightning activity probability, determine the alarm level corresponding to each divided area;

[0079] Selecting a partition area whose running status impact is less than a preset negative impact threshold as a target partition area;

[0080] According to the matching relationship between each alarm level and the target divided area, corresponding protection alarm information is generated respectively.

[0081] In this embodiment, after obtaining the current lightning activity probability and the degree of impact of the operating state, since not all power equipment in the divided areas need to be protected and alarmed, in order to further save the resource consumption of subsequent protection alarm information, the alarm level corresponding to each divided area can be determined according to the probability range corresponding to each current lightning activity probability. Then, based on the specific values ​​of the degree of impact of the operating state of each divided area, the divided area whose degree of impact of the operating state is less than the preset negative impact threshold is selected as the target divided area, and finally the target divided area is matched with the alarm level to determine the alarm level corresponding to each target divided area, thereby generating different protection alarm information.

[0082] In the specific implementation, in order to facilitate users to view the protection alarm information corresponding to each target division area, it can be marked and displayed in the form of a regional activity diagram, using colors that gradually darken as the alarm level increases, such as yellow, orange, red, black, etc.

[0083] It is worth mentioning that the three-dimensional location information and attributes of power equipment at all levels can also be superimposed on the regional activity map, including but not limited to transmission lines, power plants and substations.

[0084] Furthermore, the method further comprises the following steps S11-S13:

[0085] S11. If the operating status impact degree is less than the negative impact threshold, increase the transmission voltage corresponding to the power equipment in the divided area according to the preset voltage amplitude until the operating status impact degree is greater than or equal to the negative impact threshold;

[0086] S12. If the impact degree of the operating status is greater than or equal to the negative impact threshold and less than the damage threshold, the transmission voltage of the power equipment in the divided area is maintained at the current moment;

[0087] S13. If the impact degree of the operating status is equal to or greater than the damage threshold, the power equipment is determined to be damaged, and the current connection with the power equipment in the divided area is disconnected.

[0088] In a specific implementation, after obtaining the operating status impact degree at the current moment, in order to realize the subsequent operation regulation of the power equipment, the operating status impact degree and the negative impact threshold can be further compared.

[0089] If the operating status impact degree is less than the negative impact threshold, the transmission voltage of the power equipment is increased according to the preset voltage amplitude, and the operating status impact degree is updated in real time until the operating status impact degree is greater than or equal to the negative impact threshold; if the operating status impact degree is greater than or equal to the negative impact threshold and less than the damage threshold, it indicates that the operating status of the power equipment is good at this time and the transmission voltage of the power equipment can be maintained at the current moment; if the operating status impact degree is equal to or greater than the damage threshold, it indicates that the power equipment may have been damaged by the weather. In order to avoid further negative impacts, the power equipment is determined to be damaged at this time, and the current connection with the power equipment is disconnected, thereby ensuring the safe use of the remaining power equipment.

[0090] It is worth mentioning that after determining that the power equipment is damaged, the information about the damage of the power equipment can also be sent to the operation and maintenance personnel at the same time, so as to facilitate the operation and maintenance personnel to carry out repairs.

[0091] In another example of the present invention, the method further includes the following steps S21-S22:

[0092] S21. When a lightning strike occurs, obtain updated operating status information of each power device at the current moment;

[0093] S22, using the updated operating status information as new operating status information, jumping to the step of calculating the normalized ratio of the operating status information according to the divided areas where the power equipment is located, and obtaining the system operating status information of the power system in each divided area.

[0094] In an embodiment of the present application, when the lightning monitor detects ion information, if a lightning strike occurs, the operating status of the power equipment may change. The updated operating status information of each power equipment at the current moment can be obtained and used as the new operating status information, and the process jumps to step 102, thereby achieving real-time adjustment of the power system and real-time acquisition of the operating status of the power equipment.

[0095] It is worth mentioning that each divided area can be monitored in real time. If the line tripping information uploaded by the user is received or the operating status is detected to be abnormal, the divided area where the power equipment is located can be locked and the abnormality of a certain power equipment can be monitored again, thereby realizing the rapid positioning of the lightning damage location.

[0096] Optionally, historical lightning data statistics and current data can be summarized and processed, and the information can be uploaded in real time, such as statistics on lightning activities at key locations such as transmission lines, substations, and power plants; generate ground lightning density, lightning days, lightning hours, total number of lightning strikes, average intensity, and form daily, monthly, and annual reports; output statistical results for analysis and evaluation of the operating status of the power system.

[0097] In the embodiment of the present application, when any lightning monitor collects ion information, the operating status information of each power equipment is obtained in real time; the normalized ratio of the operating status information is calculated according to the divided area where the power equipment is located, and the system operating status information of the power system in each divided area is obtained; the ratio of each system operating status information and the preset conventional system operating status information is calculated to obtain the operating status impact degree corresponding to each divided area; based on the ion information and the historical lightning activity probability, the current lightning activity probability corresponding to each divided area is determined; according to the current lightning activity probability and the operating status impact degree, the protection alarm information corresponding to each divided area is generated respectively. Thereby solving the technical problem that the existing power system operation alarm scheme cannot realize efficient protection and early warning in lightning-prone areas because it needs to obtain the operating status of power equipment one by one for data processing. By dividing the power system into regions, the number of power system early warnings that need to be processed is reduced in the form of each divided area, thereby realizing efficient early warning in lightning-prone areas.
