Description

Technical Field

[0001] The present invention relates to the technical field of substation bird repelling, and particularly relates to an intelligent bird damage prevention and control management system and device for substations. Background Art

[0002] With the increasingly improved ecological environment and the gradually enhanced public environmental protection awareness, the activities of birds in substations have gradually increased. The activities of birds around substations are likely to cause equipment fault tripping, which has now become an important factor affecting the safe and stable operation of substations. Substation bird-related faults mainly include two categories: nest-related faults and bird droppings-related faults. Nest-related faults refer to the situation where the nesting materials of bird nests fall and short-circuit the underlying bushings, insulator strings, etc., causing the switch to trip. Bird droppings-related faults refer to the situation where bird droppings contaminate bushings, insulators, etc., reducing the insulation level and leading to flashover and causing the switch to trip.

[0003] Currently, substation bird damage prevention and control measures include two categories: substation bird damage inspections and the configuration of bird damage prevention equipment. The key point of substation bird damage inspections lies in discovering potential threats such as bird nests and bird droppings within the station. Bird damage prevention equipment mainly includes three categories: "repelling", "blocking", and "attracting". Existing research focuses on the improvement of a certain technology or the comprehensive application of multiple technologies. These two categories of bird damage prevention and control measures both focus on the station end and belong to the specific implementation measures of bird damage prevention and control. From the perspective of the bird damage prevention and control management of power grid companies, although certain achievements have been made in existing management, there are still deficiencies: first, there is a lack of quantitative understanding of substation bird damage risks, which affects the further improvement of the bird damage prevention and control effect; second, there is a lack of a comprehensive and objective evaluation of substation bird damage data, making it difficult for managers to quickly obtain key bird damage information, and the quality and efficiency of bird damage management need to be improved; third, the substation bird damage management work lacks integration and integration, and the management work efficiency needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent bird damage prevention and control management system and device for substations with better bird damage prevention and control effects and improved bird damage management quality and efficiency.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is:

[0006] An intelligent bird damage prevention and control management system for substations, comprising:

[0007] A storage unit, which is used to store the working condition data and bird damage condition data of the substation;

[0008] A data processing unit, which is used to calculate the statistical indicators and early warning indicators of substation bird damage based on the working condition data and bird damage condition data of the substation;

[0009] A bird damage active prevention and control unit, which is used to implement the bird damage prevention and control function according to the statistical indicators and early warning indicators of substation bird damage;

[0010] A visualization unit, which is used to display the statistical indicators and early warning indicators of bird damage in the substation and provide a video window for the substation.

[0011] The operating condition data of the substation includes substation attribute data, substation anti-bird damage equipment ledger data, and substation outdoor equipment area operating data; the bird damage situation data includes substation bird's nest statistics data and substation nesting bird data.

[0012] The early warning indicators include the substation bird nesting attraction indicator, the substation bird damage risk indicator, and the bird's nest defect elimination warning indicator;

[0013] The calculation method of the substation bird nesting attraction indicator is:

[0014] α i =ux i +vy i +wz i

[0015] Where α i is the substation bird nesting attraction indicator, x i is the substation outdoor / semi-outdoor / indoor station type score, y i is the score of the degree of personnel density around the substation, z i is the score of the abundance of bird food around the substation, u is the weight coefficient of the substation outdoor / semi-outdoor / indoor station type, v is the weight coefficient of the degree of personnel density around the substation, and w is the weight coefficient of the abundance of bird food around the substation;

[0016] The calculation method of the substation bird damage risk indicator is:

[0017] ρ i,t =α i β t (1 + γ t )

[0018] Where ρ i,t is the substation bird damage risk indicator, β t is the time attraction correction factor, and γ t is the substation outdoor equipment area operation addition coefficient;

[0019] The calculation method of the bird's nest defect elimination warning indicator is:

[0020] η y =(T - t y ) / T

[0021] Where η y is the bird's nest defect elimination warning indicator, and t yLet \(t\) be the existence time of the bird nest defect, and \(T\) be the time limit for handling the bird nest defect.

[0022] The data processing unit calculates the statistical indicators and the warning indicators according to a set period.

[0023] The bird damage active prevention and control unit realizes the functions of bird damage prevention and control, including targeted inspections of substations with high bird damage risks, technical guidance for substation bird damage inspections by duty officers, and management and control of temporary mobile bird damage prevention equipment.

[0024] The method for realizing targeted inspections of substations with high bird damage risks is as follows: determining the bird damage risk level of the substation based on the bird damage risk indicators of the substation and a preset risk threshold, and increasing the corresponding number of inspections on the basis of the normal inspection plan of the substation according to the bird damage risk level of the substation;

[0025] The method for realizing technical guidance for substation bird damage inspections by duty officers is as follows: sending a substation bird damage statistics and analysis report based on the bird damage situation data, the statistical indicators and warning indicators of the substation bird damage to the duty officer team;

[0026] The method for realizing management and control of temporary mobile bird damage prevention equipment is as follows: controlling the inspection robot carrying bird repellent equipment to conduct inspections and drive away birds.

[0027] If the bird damage risk levels of the substation include level I, level II, and level III, then for the substation with the bird damage risk level of level I in the substation, 1 - 2 additional inspections are added on the basis of its normal inspection plan.

[0028] A substation intelligent bird damage prevention and control management device includes the aforementioned substation intelligent bird damage prevention and control management system and an inspection robot carrying bird repellent equipment that conducts inspections under the control of the substation intelligent bird damage prevention and control management system.

[0030] The sound bird repellent device and the ultrasonic bird repellent device work alternately.

[0031] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art: The present invention can improve the effect of bird damage prevention and control, and improve the quality and efficiency of bird damage management and the work efficiency of bird damage management. Brief Description of the Drawings

[0032] Appendix Figure 1 It is a block diagram of the substation intelligent bird damage prevention and control management system of the present invention. Detailed Embodiments

[0033] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0034] Example 1: As shown in the appendix Figure 1 A smart bird damage prevention and control management system for a substation includes four functional modules: a storage unit, a data processing unit, an active bird damage prevention unit, and a visualization unit. The storage unit is unidirectionally communicatively connected to the data processing unit, and the active bird damage prevention unit and the visualization unit are respectively bidirectionally communicatively connected to the data processing unit. The specific solutions for each functional module are as follows:

[0035] 1. Storage unit

[0036] The storage unit is used to store the working condition data and bird damage data of the substation. The working condition data of the substation includes substation attribute data, substation bird damage prevention equipment inventory data, and substation outdoor equipment area working data; the bird damage data includes substation bird's nest statistics data and substation nesting bird data.

[0037] Specifically, the substation bird's nest statistics data includes the time when the bird's nest was discovered, the name of the team where the bird's nest is located, the name of the substation where it is located, the name of the equipment where it is located, the risk level of the bird's nest, and whether power outage treatment is required, etc. The substation nesting bird data includes potential nesting birds in the area where the substation is located and bird data of birds active in the substation determined through photos, videos, etc., including the type of bird, residence type, appearance characteristics, habitat environment, breeding period, bird's nest characteristics, etc. The substation attribute data includes the type of substation (outdoor / semi-outdoor / indoor), the density of people around the substation, and the abundance of bird food around the substation. The substation bird damage prevention equipment inventory data includes the name, manufacturer, installation location, technical indicators, etc. of the bird damage prevention equipment configured for each substation. The substation outdoor equipment area working data includes the work content, scope, time, etc. of the work carried out in the substation outdoor equipment area.

[0038] The storage unit uses a relational database to store substation bird's nest statistics data, substation nesting bird data, substation attribute data, substation bird damage prevention equipment inventory data, and substation outdoor equipment area working data, providing true and reliable data for the subsequent processing and analysis of the data processing unit. The storage unit requires a relatively large storage capacity and good scalability, but most of the data is entered once or periodically, and the requirement for read and write performance is not too high.

[0039] 2. Data processing unit

[0040] The data processing unit is used to calculate statistical indicators and early warning indicators of bird damage in the substation based on the working condition data and bird damage data of the substation, supporting the function realization of the active bird damage prevention unit and the visualization unit.

[0041] Specifically, the functions of the statistical indicators for bird damage in substations are as follows: enabling managers to comprehensively and quickly obtain key information from bird damage historical data and ledger data, and accurately grasping the current situation of bird damage prevention work in substations. The statistical indicators mainly include the number of bird nests found by each team, the number of bird nests found in each substation, the number of bird nests found in different equipment, the number of bird nests found in different months, the number of bird nests with different defect levels, the disposal rate of bird nest defects, the number of bird damage prevention devices in each substation, etc. The functions of the early warning indicators for bird damage in substations are to quantify the bird damage risk in substations, so as to take targeted bird damage prevention measures and improve the effect of bird damage prevention. The early warning indicators mainly include the bird nest building attraction indicator in substations, the bird damage risk indicator in substations, and the bird nest defect elimination warning indicator, etc.

[0042] The bird nest building attraction indicator in substations quantitatively evaluates and comprehensively scores substations from the perspectives of the number of potential bird nest building locations in substations, the degree of interference with bird activities, and the abundance of bird food. Its calculation method is as follows:

[0043] α i = ux i + vy i + wz i

[0044] Among them, α i is the bird nest building attraction indicator in substations, x i is the score for the type of outdoor / semi-outdoor / indoor substation, y i is the score for the degree of population density around the substation, z i is the score for the abundance of bird food around the substation, u is the weight coefficient for the type of outdoor / semi-outdoor / indoor substation, v is the weight coefficient for the degree of population density around the substation, and w is the weight coefficient for the abundance of bird food around the substation.

[0045] The bird damage risk indicator in substations, based on the quantitative analysis of the bird nest building attraction of the inherent attributes of the substation, further considers the main breeding period of birds and the impact of work in the outdoor equipment area of the substation on bird nest building. Its calculation method is as follows:

[0046] ρ i,t = α i β t (1 + γ t )

[0047] Among them, ρ i,t is the bird damage risk indicator in substations, β t is the time attraction correction factor, and γ t is the work addition coefficient in the outdoor equipment area of the substation;

[0048] The bird's nest defect elimination warning index targets critical bird's nest defects, tracks the progress of bird's nest handling, and gives warning prompts. Its calculation method is as follows:

[0049] η y =(T - t y ) / T

[0050] Where η y is the bird's nest defect elimination warning index, t y is the existence time of the bird's nest defect, and T is the time limit for handling the bird's nest defect.

[0051] In the above solution, based on the analysis of the historical data of bird's nests in the substation and the characteristics of potential nesting birds, a comprehensive evaluation method combining the expert scoring method and the analytic hierarchy process is used to determine the bird nesting attraction index and the bird damage risk index of the substation. The data processing unit receives the application requirements of the active bird damage prevention unit and the visualization unit, retrieves the required data from the storage unit, completes the calculation of relevant indicators and returns the data, providing data support for the implementation of the functions of the active bird damage prevention unit and the visualization unit.

[0052] The data processing unit calculates statistical indicators and warning indicators according to the set cycle (such as monthly or daily).

[0053] 3. Active bird damage prevention unit

[0054] The active bird damage prevention unit is used to implement the bird damage prevention function according to the statistical indicators and warning indicators of bird damage in the substation. The bird damage prevention functions implemented by the active bird damage prevention unit include targeted patrols of substations with high bird damage risks, technical guidance for substation bird damage patrols by duty officers, and management and control of temporary mobile bird damage prevention equipment, etc.

[0055] The method for implementing targeted patrols of substations with high bird damage risks is as follows: Based on the bird damage risk index of the substation and the preset risk threshold, determine the bird damage risk level of the substation, and based on the bird damage risk level of the substation, increase the corresponding number of patrols on the basis of the normal substation patrol plan. For example, relying on the bird damage risk index of the substation generated monthly by the data processing unit and the pre-determined risk threshold, determine the bird damage risk level of the substation. The bird damage risk levels of the substation include level I, level II, and level III. For the substation with a bird damage risk level of level I, increase 1 - 2 patrols on the basis of its normal patrol plan, and update and adjust monthly on a rolling basis until the annual bird damage prevention work is completed.

[0056] The method for realizing technical guidance for bird damage inspection in substations by duty officers is as follows: Taking the work team as a unit, send a substation bird damage statistics and analysis report based on bird damage situation data, statistical indicators, and early warning indicators of bird damage in the substations under the jurisdiction of the duty officer team to the duty officer team. The main content of the report includes the statistics of bird nest data in the substation in the current month, the statistics of the handling of bird nest defects, the statistics of the bird nesting locations and the corresponding number of bird nesting times in the substation, the key points and suggestions for bird damage inspection in the substation, etc., for the work team to publicize to the duty officers to assist in improving the quality and efficiency of the bird damage inspection work of the duty officers.

[0057] The method for realizing the control of temporary mobile bird damage prevention equipment is as follows: Control the inspection robot carrying bird repelling equipment and equipped with an image shooting device to conduct intelligent inspection and bird repelling according to a predetermined route. During the inspection, on the one hand, take visible light photos of the locations where birds are likely to build nests, and intelligently judge bird nests based on the image recognition results. On the other hand, use a variety of bird damage prevention equipment in combination according to the preset logic for bird repelling, including two types: sound bird repelling and ultrasonic bird repelling equipment. Among them, the predetermined route can be manually selected or recommended by the system. The preset logic for the coordinated control of bird repelling equipment is that sound bird repelling and ultrasonic bird repelling must be alternated. Sound bird repelling is to roll-play the sounds of natural enemies according to the characteristics of potential nesting birds in the substation, and update the bird natural enemy sound database at intervals. Ultrasonic bird repelling is to randomly select frequencies within a certain frequency range and emit ultrasonic waves.

[0058] The active bird damage prevention unit is a functional application unit of the substation intelligent bird damage prevention management system, which can realize the effective integration and efficient management of multiple bird damage prevention function modules and must have good scalability.

[0059] 4. Visualization unit

[0060] The visualization unit is used to display the statistical indicators and early warning indicators of bird damage in the substation and provide a video window for the substation.

[0061] Specifically, the statistical indicators and early warning indicators of bird damage in the substation displayed by the visualization unit include the number of bird nests found by each work team, the number of bird nests found in each substation, the number of bird nests found on different equipment, the number of bird nests found in different months, the number of bird nests with different risk levels, the completion rate of bird nest defect disposal, the number of bird damage prevention equipment configured in each substation, the bird nesting attraction index of the substation, the bird damage risk index, the bird damage risk level, and the bird nest defect elimination warning index, etc. The display methods include line charts, bar charts, pie charts, ring charts, area charts, shaded maps, etc. The high-definition video window of the substation can connect and control the high-definition video cameras in the substation, and focus on the construction sites and personnel inspection situations of the substations with high bird damage risks.

[0062] When the above scheme is applied, the storage unit stores various types of data, which can be divided into one-time input, scattered supplementary input, daily input, and monthly input according to the frequency of data input. One-time input data refers to the basic data input once when establishing a bird pest control management system, mainly including information on potential nesting birds in substations, attribute data of existing substations, and inventory data of bird pest prevention equipment in existing substations. Scattered supplementary input data refers to extended data supplemented and entered according to production plans and application needs, mainly including data on birds active in substations determined by photos, videos, etc., attribute data of incremental substations, and inventory data of bird pest prevention equipment in incremental substations. Daily input data refers to data input regularly every day, mainly including statistics on newly discovered bird nests in substations, handling of bird nest defects, etc. Monthly input data refers to data input regularly every month, mainly including work plans for the outdoor equipment area of ​​the substation for the next month.

[0063] Every day, the data processing unit will calculate the substation bird damage statistics indicators and bird nest elimination alarm indicators based on the updated data of the storage unit, and pass them to the visualization unit. The manager can quickly and accurately grasp the status of the substation bird damage prevention work through the indicators displayed by the visualization unit, and take timely measures such as conducting bird damage intelligent inspection robot inspections to reduce the risk of bird damage. Every month, the data processing unit will update the substation bird damage risk indicators for the next month based on the work plan of the substation outdoor equipment area for the next month, determine the substation bird damage risk level, and conduct targeted bird damage inspections for substations with bird damage level I risk. In addition, the system will regularly send the substation bird damage statistics and analysis reports automatically generated by the system to the team every month, and provide technical guidance on bird damage inspections to the duty officers.

[0064] The intelligent bird damage management system for substations proposed in the present invention can be implemented in the form of hardware combined with software functional modules and sold or used as an independent product, or it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the embodiment of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product. The computer software product is stored in a storage medium and includes several instructions for a computer device (which can be a personal computer, server, or network device, etc.) to execute all or part of the embodiments of the present invention. The aforementioned storage medium includes: a mobile storage device, ROM, RAM, a magnetic disk, or an optical disk, etc., which can store program codes.

[0065] The solution of the intelligent bird damage prevention and management device for substations constructed based on the above intelligent bird damage management system for substations is as follows: It includes the aforementioned intelligent bird damage prevention and management system for substations and an inspection robot carrying bird repelling equipment that conducts inspections under the control of the intelligent bird damage prevention and management system for substations. Among them, the bird repelling equipment includes a sound bird repelling device and an ultrasonic bird repelling device that work alternately. The inspection robot is also equipped with an image capturing device and is capable of taking pictures of bird nests and performing intelligent identification.
