Description

Technical Field

[0001] The present invention belongs to the technical field of load transfer, and in particular is a method for intelligently processing and analyzing load transfer data based on a distribution network graph model. Background Art

[0002] In the operation and management of distribution networks, load transfer is a crucial technology. When a distribution network fails or is scheduled for maintenance, it can transfer the load in the fault area or the planned maintenance area to other normally operating feeders by operating the switchgear, thereby ensuring the continuity and reliability of power supply. However, the existing load transfer technology still has some problems and challenges in practical applications. Existing load transfer technologies often lack flexibility. When faced with large-scale power outages or complex faults, traditional load transfer methods often find it difficult to quickly and accurately determine the transfer path and transfer plan, resulting in low transfer efficiency and failure to meet power supply needs in emergency situations. Existing load transfer technologies are insufficient in resource utilization. In the process of transfer, multiple factors such as load conditions, grid structure, and safety often need to be considered, while traditional load transfer methods often find it difficult to comprehensively consider and optimize these factors, resulting in waste of resources or poor transfer effects.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0042] Figure 1 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0043] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments 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.

[0044] like Figure 1 As shown, a method for intelligent processing and analysis of load transfer data based on a distribution network diagram model includes:

[0045] Step 1: Establish a distribution network topology diagram, obtain the transfer condition information in real time, and determine the transfer area based on the transfer condition information;

[0046] In one embodiment, the method for establishing a distribution network topology diagram is as follows:

[0047] Collect relevant graphics and model data from the distribution network system and mark them as graph data, which includes information about equipment such as lines, transformers, and switches. Use these graph data to build a distribution network topology map, which is marked as an initial graph. The initial graph can be established based on existing methods; this initial graph can clearly show the connection relationship between various devices in the distribution network.

[0048] The initial map is divided and analyzed progressively in real time to form several unit areas, that is, the unit areas are dynamically updated according to the changes in the distribution network;

[0049] Perform a power transfer simulation on each unit area to determine whether each unit area can be further progressively divided when there are abnormal points. If it cannot be divided, no corresponding processing is performed. If it can be divided, a potential unit adjustment method is formed, and the potential unit adjustment method is associated with the corresponding unit area in the initial map, so that when there are abnormal points in the unit area in the future, the corresponding potential unit adjustment method can be directly determined;

[0050] Mark the current initial map as the distribution network model topology map.

[0051] In one embodiment, the method of performing progressive segmentation analysis on the initial graph includes:

[0052] Step SA1: Set the unit area definition. The unit area definition means that the distribution network area can be regarded as an independent area with the following characteristics: Clear boundaries: independent areas have clear geographical or electrical boundaries, which are usually divided by switchgear (such as circuit breakers, disconnectors, etc.). These switchgears play the role of isolation and connection in the transfer process, ensuring that the load can be safely transferred from one area to another. Independent load: The loads in the independent area are relatively independent, that is, they can be transferred without relying on the loads in other areas. This requires that the loads in the independent area have a certain degree of flexibility and adjustability so that they can adapt to different power supply needs during the transfer process. Independent transfer path: Each independent area should have an independent transfer path, which can be adjacent feeders, backup power supplies or other available power supply lines. The selection of the transfer path should be based on a comprehensive consideration of multiple factors such as load conditions, grid structure, and safety to ensure the smooth progress of the transfer process. Operable switchgear: The switchgear in the independent area should have good operability and reliability so that the switch operation can be accurately performed during the transfer process. At the same time, these switchgear should also have sufficient capacity and stability to withstand load changes during the transfer process.

[0053] Step SA2: According to the unit area definition, the initial map is identified in real time, and each distribution network area that meets the unit area definition is marked as a unit area; the unit area is marked in the initial map;

[0054] Step SA3: Re-identify each unit area according to the unit area definition to determine whether each unit area has a distribution network area that meets the unit area definition; because the unit area may be composed of multiple subdivided distribution network areas that meet the unit area definition, a progressive judgment analysis is required; obtain a definition judgment result, which is that there is no distribution network area that meets the unit area definition in the unit area or there is a distribution network area that meets the unit area definition in the unit area;

[0055] Step SA4: when the definition judgment result is that there is no distribution network area that meets the definition of the unit area in the unit area, the unit area is marked with a corresponding prompt label, indicating that no subsequent progressive analysis is required for the unit area with the prompt label;

[0056] When the definition judgment result is that there is a distribution network area that meets the unit area definition in the unit area, the unit area is split to form a new unit area, and the new unit area is marked in the initial map; and the unit area to be split has been marked in the initial map, and the unit area will not be unrecognizable in the initial map due to the splitting of the unit area, that is, the mark will not be cancelled; for example, unit area A is composed of two parts, B and C. If either B or C meets the unit area definition, unit area A can be split. If both B and C meet the definition, it is split into two new unit areas, B and C. The initial map is marked with three unit areas A, B, and C. If B meets the definition, a new unit area B is split; and return to step SA3;

[0057] Step SA5: loop step SA4 until there is no distribution network area in each unit area that meets the unit area definition, and then end the analysis.

[0058] In one embodiment, a method for simulating power transfer for a unit area includes:

[0059] Determine the possible abnormal points in the unit area, determine the possible abnormal points such as faulty equipment and maintenance points according to the actual distribution network situation, simulate each abnormal point, that is, simulate the abnormal point in the unit area, analyze how to adjust it to isolate the abnormal point and minimize the impact as much as possible, and form a potential unit adjustment method, that is, the potential unit adjustment method is used to isolate the impact of the abnormal point to the greatest extent; determine based on the current processing method;

[0060] Label the corresponding outlier points according to the potential unit adjustment method.

[0061] In one embodiment, a power transfer simulation is performed on the unit area, and simulation analysis can also be performed based on existing technologies.

[0062] In one embodiment, as the system runs, a large amount of material data for updating the distribution network model topology map will be accumulated. According to the material data, a corresponding training set can be set up, and then an intelligent model can be established based on existing intelligent technology. Subsequently, the distribution network model topology map is intelligently updated according to the intelligent model, including the update and adjustment of potential unit adjustment methods.

[0063] The transfer condition information is abnormal point information such as fault point information and maintenance point information determined based on corresponding fault location systems, maintenance systems, etc.

[0064] The transfer area can be determined based on the abnormal point information clearly defined in the transfer condition information; that is, the transfer area is determined using existing methods, such as locating the abnormal point in the corresponding unit area, and adjusting it according to the unit adjustment method corresponding to the abnormal point in the unit area, so as to quickly isolate the abnormal point; and then determine the transfer area.

[0065] Step 2: Identify the unit areas corresponding to the transfer area according to the distribution network model topology diagram, identify the inclusion relationship and unit information of each unit area, the unit information includes the load, equipment and other related information of the unit area; determine each benchmark area according to the inclusion relationship and unit information of each unit area, that is, to subsequently transfer each benchmark area as a whole.

[0066] In one embodiment, the method for determining each reference area according to the inclusion relationship and unit information of each unit area includes:

[0067] Set the base area definition. The base area definition is the same as the unit area definition. Both require that it can be used as an independent area for transfer. That is, it is necessary to ensure that each base area can include all transfer areas in the future. For example, if unit area A is composed of two parts, B and C, and B is also a unit area, then B cannot be used as the base area. Otherwise, the remaining C will not be able to transfer independently. Therefore, A needs to be used as the base area.

[0068] According to the definition of the benchmark area and the inclusion relationship of the unit area, the transfer area is combined and analyzed to form various candidate combination methods, which are composed of the candidate benchmark areas, and the combined area of ​​the candidate benchmark areas is equal to the transfer area; that is, according to the definition of the benchmark area, each unit area that can be used as the benchmark area is determined and marked as the candidate benchmark area, and each candidate benchmark area is combined according to the requirement that the combination is equal to the transfer area, to form various combination methods, which are marked as candidate combination methods;

[0069] The candidate combinations are screened to determine a target combination, and the candidate reference areas in the target combination are marked as reference areas.

[0070] In one embodiment, each candidate combination method may be screened based on an existing screening method.

[0071] In one embodiment, the method for screening each candidate combination includes:

[0072] The user sets a benchmark load, that is, the user expects the transfer load of each benchmark area to be the benchmark load, and the user sets it from the perspective of the impact of transfer, such as the impact on power quality;

[0073] Identify the transfer load corresponding to each candidate reference area in the candidate combination mode, and identify it according to the corresponding unit information; mark the transfer load as FZi, i represents the number corresponding to the corresponding candidate reference area, i=1, 2, ..., n, n is the number of candidate reference areas in the candidate combination mode;

[0074] Substituting the base load and the transfer load of each candidate base area in the corresponding candidate combination into a preset screening formula, and calculating the screening value of the corresponding candidate combination;

[0075] The candidate combination with the smallest screening value is marked as the target combination.

[0076] In one embodiment, the screening formula is: Where: PD is the screening value; BF is the benchmark load.

[0077] In one embodiment, it can be considered that the larger the deviation, the lower the priority, so the deviation impact can be amplified by applying an exponential function, such as setting the base number to 1.1, 1.2, 2, 2.3, etc., which is specifically set according to user needs. The screening formula is: Where: PD is the screening value; BF is the benchmark load; λ is the preset base number, λ>1.

[0078] In other embodiments, the screening formula may also be other existing formulas.

[0079] Step 3: Determine the priority of each benchmark area and determine the transfer method for each benchmark area based on the preset transfer library.

[0080] In one embodiment, the importance of different benchmark areas varies. For example, if a benchmark area has important facilities such as a hospital, its priority will be higher than that of a general benchmark area. Therefore, conducting a transfer analysis based on the priority of each benchmark area will minimize the adverse impact. Specifically, the priority of each benchmark area can be determined based on existing technologies.

[0081] In one embodiment, a method for determining the priority of a reference area includes:

[0082] Obtain a regional information map, which is used to count the information of electricity users in each unit area of ​​the distribution network area, such as factories, office buildings, shopping malls, residences, hospitals and other electricity users; based on the user's priority requirements for different electricity users, mark the corresponding single priority value for each electricity user in the regional information map, such as setting a fixed single priority value for different types of electricity users, and then matching them; you can also preset coefficients for different types of electricity users, and then multiply the coefficients by the corresponding electricity consumption scale to calculate the single priority value; the value range of the single priority value can be defined as [0, 100], and corresponding electricity user reference information is set for different single priority values, and then matching can be performed, and it can also be corrected by combining the interpolation method to determine the single priority value of each electricity user in each unit area; there are multiple ways to set the single priority value of different electricity users in the unit area, and an intelligent model can be established based on a neural network, etc., to determine the single priority value through the intelligent model;

[0083] Identify the single priority value of each electricity user in the reference area, and add up the single priority values ​​of each electricity user to obtain the regional priority value of the reference area;

[0084] The priority of each reference area is determined according to the area priority value of each reference area.

[0085] In one embodiment, the transfer library is established in the following manner:

[0086] According to the definition of the benchmark area, various benchmark areas that may exist in the distribution network model topology map are determined, and optional transfer modes are set for each benchmark area, marked as the transfer modes to be selected, that is, the sequence of transfer modes to be selected for each benchmark area is formed according to the priority application method, and then the transfer library is established. That is, the transfer library is pre-set to consider possible transfer situations, which is convenient for direct matching of the corresponding transfer mode in the subsequent process and reduces the time for transfer analysis.

[0087] In one embodiment, the method for determining the transfer mode of the reference area according to the transfer library includes:

[0088] Step SC1: Mark the highest priority benchmark area for which the transfer mode has not been determined as the analysis area; when there is no analysis area, end the analysis;

[0089] Step SC2: Match each candidate transfer mode from the transfer library according to the analysis area; perform transfer evaluation according to the order of the candidate transfer modes until it is determined that the transfer requirements are met, and use the corresponding candidate transfer mode as the transfer mode for the analysis area; and return to step SC1.

[0090] The selected power transfer mode is evaluated to evaluate the power transfer path of the selected power transfer mode, identify the path information of the power transfer path, such as load rate, load rate threshold, rated current of the switch, opening and closing time, etc., to indicate whether the current power transfer path can bear the power transfer adjustment of the reference area, including the load of the reference area with the highest priority applying the power transfer path, etc., for comprehensive judgment; the power transfer judgment is made according to the path information to determine whether the power transfer requirements are met. The evaluation is carried out using the existing power transfer judgment method.

[0091] Step 4: Carry out the transfer process according to the transfer method of each benchmark area.

[0092] The above formulas are all calculated by removing dimensions and taking numerical values. The formula is a formula that is closest to the actual situation obtained by collecting a large amount of data and performing software simulation. The preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained by simulating a large amount of data.

[0093] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
