Description

Technical Field

[0001] The present invention belongs to the technical field of electric power inspection and maintenance, and more specifically, relates to an electric power maintenance dispatching method and a dispatching system. Background Art

[0002] As electricity consumption in various industries continues to increase, higher requirements are placed on the safety and reliability of power system operation. Effective maintenance of the power system is an important prerequisite for enhancing the safety and stability of the entire system.

[0003] Power maintenance is also known as power operation and maintenance, or simply power operation and maintenance. Power maintenance refers to the regular inspection, repair, maintenance and emergency troubleshooting of power systems and equipment to ensure the stability, safety and reliability of power supply. Power maintenance covers all aspects from power generation, transmission, transformation, distribution to power consumption.

[0004] In the prior art, when performing power maintenance, power maintenance personnel usually conduct regular inspections and maintenance of power equipment and lines at a specified time, and then fill in inspection and maintenance records. For emergency failures, the dispatcher needs to assign power maintenance personnel to handle the emergency, and then fill in the emergency handling record. This method requires more personnel to intervene, and the process is usually chaotic, which is prone to deviations and omissions in inspections and maintenance, as well as untimely emergency handling. Summary of the invention

[0005] The purpose of the present invention is to provide a power maintenance scheduling method, which aims to solve the problems of power maintenance personnel having a chaotic process, prone to deviations and omissions, and untimely processing when performing power maintenance.

[0006] To achieve the above object, the technical solution adopted by the present invention is: to provide a power maintenance scheduling method, comprising the following steps: S1: Define the power system as multiple maintenance units, input the multiple maintenance units into the dispatching system, and build a neural network with multiple maintenance lines using the multiple maintenance units as nodes; S2: Build working condition models of different dispatching levels based on the correlation of multiple maintenance lines, set interactive terminals on the maintenance unit and set evaluation rules. Each interactive terminal is associated with multiple mobile interactive terminals, and daily maintenance parameters and emergency start and stop parameters are preset for the interactive terminal. S3: The maintenance parameters of the interactive terminal corresponding to the working condition model are formed in an array manner and sent to the mobile interactive terminal, and the mobile interactive terminal feeds back the maintenance information to the interactive terminal, simulates and runs the corresponding working condition model, and determines the power maintenance effect according to the evaluation rules of the interactive terminal.

[0007] In a possible implementation, in step S1, when multiple maintenance units are defined in the power system, a virtual circle is constructed with a main power device as the center, adjacent virtual circles are tangent to each other and two common tangent lines are drawn in a manner of being tangent to the two virtual circles, and an area jointly constructed by the two common tangent lines and the corresponding two virtual circles forms a maintenance unit; If the overlapping area formed between two adjacent maintenance units is located in the same working condition model, the evaluation rules set by the interactive terminals in the two adjacent maintenance units are the same; If the overlapping area formed between two adjacent maintenance units is located in different working condition models, the interactive terminals in the two adjacent maintenance units need to set two evaluation rules according to the weight ratio.

[0008] In a possible implementation, when a virtual circle is constructed with a main power equipment as the center, a low-level virtual circle, a middle-level virtual circle and a high-level virtual circle are constructed in layers in the height direction, and virtual circles in the same layer are tangent to each other and corresponding common tangent lines are drawn; The height of the low-level virtual circle is A, the height of the middle-level virtual circle is B, and the height of the high-level virtual circle is C, wherein A>B>C.

[0009] In a possible implementation, in step S2, when constructing the operating condition models of different scheduling levels based on the association of multiple maintenance lines, multiple maintenance lines are associated with the power consumption type or power consumption area of ​​the power customer to finally form the power consumption operating condition model; or multiple maintenance lines are associated with the power distribution demand of the power supply equipment to finally form the power supply operating condition model; Among them, the power consumption condition model and the power supply condition model exist at the same time. When setting the evaluation rules for the interactive terminal, two evaluation rules for the power consumption condition model and the power supply condition model need to be set respectively.

[0010] In a possible implementation, in step S2, each interactive terminal is associated with multiple mobile interactive terminals, and each mobile interactive terminal is also associated with multiple interactive terminals at the same time, and the multiple interactive terminals and the multiple mobile interactive terminals form an interactive network model.

[0011] In a possible implementation, in step S2, the daily maintenance parameters include basic life parameters, operating time parameters, maintenance frequency parameters, single consumable cost parameters, and personnel configuration parameters; The basic life parameters are based on the service life of the main power equipment and vulnerable parts, combined with the impact of environmental factors on the equipment and vulnerable parts, to form corresponding data; The operating time parameter is set based on the time difference between the initial installation of the equipment and the first maintenance, or the time difference between adjacent maintenances. The operating time parameter is gradually shortened over time. The maintenance frequency parameter and the single consumable cost parameter are both reference data. The maintenance frequency parameter is the average of the maintenance frequency of the same equipment in the same environment during its entire life cycle. The single consumable cost parameter is the sum of the maintenance consumable costs of the same equipment in the same environment during its entire life cycle divided by the maintenance frequency. The personnel configuration parameters are initial setting parameters, which are determined according to the level of the working condition model where the interactive terminal is located.

[0012] In a possible implementation, in step S2, the emergency start-stop parameters include environmental change parameters, system operation parameters, and personnel configuration parameters; The environmental change parameters are based on the operating temperature and humidity of the environment in which the main power equipment and vulnerable parts are located. The actual temperature and humidity of the environment in which the main power equipment and vulnerable parts are located are measured by temperature and humidity detection elements. The actual temperature is compared with the operating temperature, and the actual humidity is compared with the operating humidity. If the difference between the two exceeds the allowable deviation value, an emergency response event is initiated and fed back to the mobile interactive terminal through the dispatch system; The system operation parameters are based on the operating voltage and operating current of the main power equipment and vulnerable parts. The actual voltage and actual current of the main power equipment and vulnerable parts are measured by voltage detection elements and current detection elements. The actual voltage is compared with the operating voltage, and the actual current is compared with the operating current. If the difference between the two exceeds the allowable deviation value, the emergency response event is initiated and fed back to the mobile interactive terminal through the dispatch system; The personnel configuration parameters are initial setting parameters, which are determined according to the level of the working condition model where the interactive terminal is located. When the emergency response event is initiated, the dispatching system will send an emergency start signal to the mobile interactive terminals of the corresponding number of maintenance personnel according to the set personnel configuration parameters.

[0013] In a possible implementation, in step S3, the maintenance parameter of the interactive terminal is a comprehensive parameter generated based on the daily maintenance parameter and the emergency start-stop parameter and combined with the level of the working condition model; After completing the maintenance, the maintenance personnel confirm the work area information, personnel configuration information and work duration information included in the comprehensive parameters on the mobile interactive terminal, and fill in the equipment replacement / repair / maintenance details. The maintenance status information of the maintenance unit is also required to be captured by video.

[0014] In a possible implementation, in step S3, when simulating the operation of the corresponding operating condition model, the operating condition model is first operated normally with the initial setting value of the operating condition model and maintained for more than 1 hour, and then operated with the initial safety value load of the operating condition model and maintained for more than half an hour; If both normal operation and load operation meet the requirements, the power maintenance effect is determined in combination with the judgment rules in the interactive terminal and recorded in the dispatching system to form historical sample vector information, which is rolled over to participate in subsequent power maintenance actions; If at least one of the routine operation and load operation does not meet the requirements, the maintenance parameters of the interactive terminal are readjusted and human intervention is performed to feed back information to the interactive terminal again until the simulated routine operation and load operation loads both meet the requirements. The power maintenance effect is determined based on the judgment rules in the interactive terminal and recorded in the dispatching system to form historical sample vector information. The historical sample vector information is rolled over to participate in subsequent power maintenance behaviors. The beneficial effect of a power maintenance scheduling method provided by the present invention is that: compared with the prior art, the power system is defined as multiple maintenance units, the multiple maintenance units are input into the scheduling system, and a neural network with multiple maintenance lines is constructed with multiple maintenance units as nodes; the working condition models of different scheduling levels are constructed with the correlation of multiple maintenance lines, an interactive terminal is set on the maintenance unit and an evaluation rule is set, each interactive terminal is associated with multiple mobile interactive terminals, and daily maintenance parameters and emergency start-stop parameters are preset for the interactive terminal; the maintenance parameters of the interactive terminal corresponding to the working condition model are formed in an array manner and sent to the mobile interactive terminal, the mobile interactive terminal feeds back maintenance information to the interactive terminal, the corresponding working condition model is simulated and the power maintenance effect is determined by the evaluation rules of the interactive terminal. A power maintenance scheduling method provided by the present invention forms the maintenance parameters of the interactive terminal in the corresponding working condition model and sends them to the mobile interactive terminal by presetting the daily maintenance parameters and emergency start-stop parameters of the interactive terminal, the maintenance personnel obtain the specific information of the power maintenance in time through the mobile interactive terminal, and then use the mobile interactive terminal to feed back to the interactive terminal after completing the operation, and finally simulates the running working condition model and determines the power maintenance effect by the evaluation rules of the interactive terminal. By using the power maintenance scheduling method provided by the present invention, power maintenance personnel can have a smoother process when performing power maintenance, can provide timely feedback on information, and are less likely to have problems such as deviations, omissions, and untimely processing.

[0015] The present invention also provides a power maintenance dispatching system, which is applied to the power maintenance dispatching method.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Unless explicitly defined otherwise, the use of terms such as "first," "second," or "third," etc., are intended to distinguish different objects rather than to describe a specific order.

[0022] Referring to the figure and the figure, a power maintenance scheduling method provided by the present invention is now described. The power maintenance scheduling method comprises the following steps: S1: Define the power system as multiple maintenance units, input the multiple maintenance units into the dispatching system, and build a neural network with multiple maintenance lines using the multiple maintenance units as nodes; S2: Build working condition models of different dispatching levels based on the correlation of multiple maintenance lines, set interactive terminals on the maintenance unit and set evaluation rules. Each interactive terminal is associated with multiple mobile interactive terminals, and daily maintenance parameters and emergency start and stop parameters are preset for the interactive terminal. S3: The maintenance parameters of the interactive terminal corresponding to the working condition model are formed in an array manner and sent to the mobile interactive terminal, and the mobile interactive terminal feeds back the maintenance information to the interactive terminal, simulates and runs the corresponding working condition model, and determines the power maintenance effect according to the evaluation rules of the interactive terminal.

[0023] The present invention provides a power maintenance scheduling method. Compared with the prior art, the power system is defined as multiple maintenance units, multiple maintenance units are input into the scheduling system, and a neural network with multiple maintenance lines is constructed with multiple maintenance units as nodes; the working condition models of different scheduling levels are constructed with the correlation of multiple maintenance lines, and interactive terminals are set on the maintenance units and evaluation rules are set. Each interactive terminal is associated with multiple mobile interactive terminals, and daily maintenance parameters and emergency start-stop parameters are preset for the interactive terminal; the maintenance parameters of the interactive terminal corresponding to the working condition model are formed in an array manner and sent to the mobile interactive terminal, and the mobile interactive terminal feeds back maintenance information to the interactive terminal, simulates the operation of the corresponding working condition model, and determines the power maintenance effect by the evaluation rules of the interactive terminal. The present invention provides a power maintenance scheduling method. By presetting the daily maintenance parameters and emergency start-stop parameters of the interactive terminal, the maintenance parameters of the interactive terminal in the corresponding working condition model are formed and sent to the mobile interactive terminal, and the maintenance personnel obtain the specific information of the power maintenance in time through the mobile interactive terminal, and then use the mobile interactive terminal to feed back to the interactive terminal after completing the operation, and finally simulates the operation of the working condition model and determines the power maintenance effect by the evaluation rules of the interactive terminal. By using the power maintenance scheduling method provided by the present invention, power maintenance personnel can have a smoother process when performing power maintenance, can provide timely feedback on information, and are less likely to have problems such as deviations, omissions, and untimely processing.

[0024] In step S1, when multiple maintenance units are defined in the power system, a virtual circle is constructed with a main power equipment as the center, adjacent virtual circles are tangent to each other and two common tangent lines are drawn in a tangent manner to the two virtual circles, and the area jointly constructed by the two common tangent lines and the corresponding two virtual circles forms a maintenance unit; if the overlapping area formed between two adjacent maintenance units is located in the same operating condition model, the evaluation rules set for the interactive terminals in the two adjacent maintenance units are the same; if the overlapping area formed between two adjacent maintenance units is located in different operating condition models, the interactive terminals in the two adjacent maintenance units need to set two evaluation rules according to the weight ratio.

[0025] Among them, the main power equipment refers to power supply equipment, transformers (substations), switchgear (distribution cabinets), and power equipment (user end). In addition, areas where power components such as capacitors and resistors are concentrated are also defined as main power equipment, that is, areas with more than or equal to 10 power components in a cube.

[0026] When constructing a virtual circle with a main power equipment as the center, the low-level virtual circle, the middle-level virtual circle and the high-level virtual circle are layered and constructed separately in the height direction. The virtual circles in the same layer are tangent to each other and the corresponding tangent lines are drawn; the height of the low-level virtual circle is A, the height of the middle-level virtual circle is B, and the height of the high-level virtual circle is C, where A>B>C.

[0027] It is necessary to consider the difficulty of high-altitude work, so A>B>. Among them, the value of A is generally not greater than 10m, and the value of C is not greater than 5m.

[0028] In step S2, when constructing operating condition models of different scheduling levels based on the correlation of multiple maintenance lines, multiple maintenance lines are associated with the power customer's power consumption type or power consumption area to ultimately form a power consumption operating condition model; or multiple maintenance lines are associated with the power distribution requirements of the power supply equipment to ultimately form a power supply operating condition model; the power consumption operating condition model and the power supply operating condition model exist at the same time, and when setting evaluation rules for the interactive terminal, two evaluation rules need to be set for the power consumption operating condition model and the power supply operating condition model respectively.

[0029] When conducting routine inspections and maintenance, it is necessary to take into account both the power consumption condition model and the power supply condition model. When conducting emergency fault handling, it is necessary to focus on the evaluation rule that has a greater impact on the power user or power supplier, and the other evaluation rule is used as an auxiliary evaluation or verification evaluation.

[0030] In step S2, each interactive terminal is associated with multiple mobile interactive terminals, and each mobile interactive terminal is also associated with multiple interactive terminals at the same time, and multiple interactive terminals and multiple mobile interactive terminals form an interactive network model. In other words, each mobile interactive terminal is associated with multiple interactive terminals, and each angle terminal is also associated with multiple mobile interactive terminals. The power maintenance personnel can complete the feedback of any interactive terminal through all mobile interactive terminals, and similarly, one interactive terminal can also receive information from all mobile interactive terminals.

[0031] In step S2, daily maintenance parameters include basic life parameters, operating time parameters, maintenance frequency parameters, single consumable cost parameters and personnel configuration parameters.

[0032] The basic life parameters are based on the service life of the main power equipment and vulnerable parts, combined with the impact of environmental factors on the equipment and vulnerable parts, to form corresponding data. The basic life parameters are the basic parameters of daily maintenance parameters, directly reflecting the service life of the main power equipment and vulnerable parts, and combined with the influence of temperature and humidity in the on-site environment, and the actual service life is pre-defined.

[0033] The operating time parameter is set based on the time difference between the initial installation time of the equipment and the first maintenance time, or the time difference between adjacent maintenance times. Taking into account the accumulation of operating time and maintenance times, the operating time parameter gradually shortens over time. In other words, the reliability of the equipment will decrease with the operating time and maintenance times.

[0034] The maintenance frequency parameter and the single consumable cost parameter are both reference data. The maintenance frequency parameter is the average of the maintenance frequency of the same equipment in the same environment during its entire life cycle, and the single consumable cost parameter is the sum of the maintenance consumable costs of the same equipment in the same environment during its entire life cycle divided by the maintenance frequency. The maintenance frequency parameter reflects the frequency of equipment maintenance and objectively reflects the reliability of equipment operation. The single consumable cost refers to the cost of one maintenance. The two need to be considered comprehensively, taking into account both maintenance efficiency and maintenance costs.

[0035] The personnel configuration parameters are initial setting parameters, which are determined according to the level of the working condition model where the interactive terminal is located. The personnel configuration parameters are variable values ​​and can be adjusted through the evaluation results after maintenance to achieve the optimal personnel configuration. At the same time, they change with the changes in maintenance frequency and single consumable costs.

[0036] In step S2, the emergency start-stop parameters include environmental change parameters, system operation parameters, and personnel configuration parameters.

[0037] The environmental change parameters are based on the operating temperature and humidity of the environment in which the main power equipment and vulnerable parts are located. The actual temperature and humidity of the environment in which the main power equipment and vulnerable parts are located are measured through temperature and humidity detection elements. The actual temperature is compared with the operating temperature, and the actual humidity is compared with the operating humidity. If the difference between the two exceeds the allowable deviation value, an emergency response event is initiated and fed back to the mobile interactive terminal through the dispatch system. When the actual temperature and humidity of the environment in which the main power equipment and vulnerable parts are located change dramatically, an emergency response event needs to be initiated for timely maintenance, which can avoid equipment failures in advance or discover equipment hazards early.

[0038] The system operating parameters are based on the operating voltage and operating current of the main power equipment and vulnerable parts. The actual voltage and actual current of the main power equipment and vulnerable parts are measured through voltage detection elements and current detection elements. The actual voltage is compared with the operating voltage, and the actual current is compared with the operating current. If the difference between the two exceeds the allowable deviation value, an emergency response event is initiated and fed back to the mobile interactive terminal through the dispatch system. When the operating voltage and operating current of power equipment and vulnerable parts change drastically, an emergency response event needs to be initiated for timely maintenance, which can avoid equipment failures in advance or discover equipment hazards early.

[0039] The personnel configuration parameters are initial setting parameters, which are determined according to the level of the working condition model where the interactive terminal is located. When the emergency response event is initiated, the dispatching system will send an emergency start signal to the mobile interactive terminals of the corresponding number of maintenance personnel according to the set personnel configuration parameters.

[0040] In step S3, the maintenance parameters of the interactive terminal are comprehensive parameters generated based on daily maintenance parameters and emergency start-stop parameters combined with the level of the working condition model; after completing the maintenance, the maintenance personnel confirm the operation area information, personnel configuration information and operation time information contained in the comprehensive parameters on the mobile interactive terminal, and fill in the equipment replacement / repair / maintenance details, and also need to collect the maintenance status information of the maintenance unit through video. The operation area information, personnel configuration information, operation time information, replacement / repair / maintenance details and maintenance status information in the above comprehensive parameters are fed back to the interactive terminal and integrated into comprehensive information to correspond to the evaluation rules to determine the effect of power maintenance.

[0041] In step S3, when simulating the operation of the corresponding operating condition model, firstly, the operating condition model is operated normally with the initial setting value and maintained for more than 1 hour, and then the operating condition model is operated with the initial safety value load and maintained for more than half an hour; if both the normal operation and the load operation meet the requirements, the power maintenance effect is determined in combination with the judgment rules in the interactive terminal and recorded in the dispatching system to form historical sample vector information, and the historical sample vector information is rolled to participate in the subsequent power maintenance behavior; if at least one of the normal operation and the load operation does not meet the requirements, the maintenance parameters of the interactive terminal are readjusted and human intervention is performed to re-feed back information to the interactive terminal until the simulated normal operation and load operation loads meet the requirements, the power maintenance effect is determined in combination with the judgment rules in the interactive terminal and recorded in the dispatching system to form historical sample vector information, and the historical sample vector information is rolled to participate in the subsequent power maintenance behavior.

[0042] Based on the same inventive concept, the present invention also provides a power maintenance and dispatching system. Since the power maintenance and dispatching system is applied to the above-mentioned power maintenance and dispatching method, it has the same beneficial effects as the above-mentioned power maintenance and dispatching method, which will not be repeated here.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
