Description

Technical Field

[0001] The present invention belongs to the technical field of acceptance management, and in particular relates to a one-button sequential control automatic acceptance method and medium for a transformer substation. Background Art

[0002] Substation one-touch sequential control utilizes intelligent technology and network communication technologies, supported by a substation equipment linkage control system, to achieve automated, centralized, and coordinated control of all substation equipment. Users can easily complete the entire process through a single terminal device, eliminating the need for human interaction.

[0003] In order to implement the acceptance of the one-button sequential control of substations, the invention patent application CN202411121267.6 "A method, device, equipment and medium for automatic acceptance of one-button sequential control of substations without power outage" sequentially inputs each instruction in the sequential control instruction set into the one-button sequential control test system for logic verification. Based on the results of the logic verification, the one-button sequential control acceptance of the target substation is implemented, thereby significantly improving the efficiency of the one-button sequential control acceptance. However, there are the following technical problems: When conducting the acceptance process of one-button sequential control, the existing technical solutions ignore the failure risk of substation equipment. When a substation equipment fails, it is often necessary to isolate the faulty equipment through one-button sequential control. At the same time, the failure of the substation equipment may cause the one-button sequential control system to be unable to perform control processing in a timely and effective manner. Therefore, if the failure risk of the substation equipment is ignored during the acceptance process, the accuracy of the acceptance result of the one-button sequential control cannot be guaranteed.

[0004] In order to solve the above technical problems, the present application provides a substation one-button sequential control automatic acceptance method and medium. Summary of the Invention

[0005] To achieve the purpose of the present invention, the present invention adopts the following technical solutions: In a first aspect, the present application provides a one-button sequential control automatic acceptance method for a substation, specifically comprising: S1 performs different one-button sequential control operation types on associated power equipment using the one-button sequential control operation logic of the substation, and when it is determined based on analysis results of operation and maintenance data of different associated power equipment that the operation type requires consideration of the failure risk of the associated power equipment, proceeds to the next step; S2 determines associated risk faults of different associated power equipment and the determination of risk power equipment based on the analysis results of the operation and maintenance data of different associated power equipment, and determines the fault-associated power equipment of the risk power equipment based on the historical failure times of the risk power equipment under different associated risk faults and the failure data of the power equipment of the substation; S3 determines that when the acceptance risk of the operation type meets the requirements based on the overlapping data of the fault-associated power equipment of different risk power equipment and the associated power equipment of the operation type, the acceptance method of different associated power equipment during the acceptance processing in the operation type is determined based on the fault association situation of different associated power equipment at different risk power equipment.

[0006] The beneficial effects of the present invention are: Based on the analysis results of the operation and maintenance data of different associated power equipment, it is determined whether the operation type needs to consider the failure risk of the associated power equipment, thereby realizing the determination of whether the operation type has the failure risk of the power equipment during operation from the perspective of the equipment failure risk of the associated power equipment of the one-button sequential control operation type, avoiding the technical problem of low efficiency of automatic acceptance processing caused by considering the failure risk in the acceptance processing of all one-button sequential controls, and at the same time ensuring the reliability of the acceptance processing of the one-button sequential control operation type that has the failure risk.

[0007] Based on the fault correlation of different associated power equipment with different risk power equipment, the acceptance method of different associated power equipment during the acceptance processing in the operation type is determined, and the differences in the risks of failure of associated power equipment during the operation of one-button sequential control due to the fault correlation with different risk power equipment are comprehensively considered, thereby realizing differentiated settings of equipment status during acceptance processing according to the risk of failure, and further improving the reliability of the acceptance processing of one-button sequential control.

[0008] A further technical solution is that the associated power equipment is the power equipment involved in the operation process of the one-button sequential control operation type.

[0009] A further technical solution is that the operation and maintenance data of the associated power equipment includes the number of risk locations of the associated power equipment and associated fault types of different risk locations.

[0010] A further technical solution is that the risk position is a position where the inspection data is not within a preset indicator range.

[0011] A further technical solution is that determining the operation type needs to consider the failure risk of the associated power equipment, specifically including: Determining the number of risk locations of the power equipment associated with the operation type based on operation and maintenance data of the power equipment associated with the operation type; Treat the associated power equipment in risky locations as risky power equipment; According to the number of the risky power devices, it is determined whether the operation type needs to consider the failure risk of the associated power devices.

[0012] A further technical solution is that when the proportion of the risky power equipment in the associated power equipment in the operation type is greater than a preset risk equipment proportion, it is determined that the operation type needs to consider the failure risk of the associated power equipment.

[0013] A further technical solution is that, when the operation type does not need to consider the failure risk of the associated power equipment, the failure risk of the associated power equipment does not need to be considered when performing the automatic acceptance processing of the operation type.

[0014] A further technical solution is that the method for determining the acceptance mode of the associated power equipment during the acceptance process in the operation type is: Based on the fault correlation between different associated power equipment and different risk power equipment, determine the risk power equipment associated with different associated power equipment, and use them as associated risk power equipment; The proportion of the number of risk power equipment associated with the associated power equipment in the associated power equipment of the operation type is used as the associated quantity proportion; An acceptance method for the associated power equipment during acceptance processing in the operation type is determined based on the associated quantity ratio.

[0015] A further technical solution is to determine the acceptance method of the associated power equipment during the acceptance process in the operation type based on the associated quantity ratio, specifically including: When the proportion of the associated number is greater than a preset threshold of the proportion of the associated number, the associated power equipment is set as faulty or non-faulty during the acceptance process in the operation type; When the proportion of the associated number is not greater than the preset threshold value of the proportion of the associated number, during the acceptance processing of the operation type, the associated power equipment will only be considered to be in failure and non-failure when its associated risk power equipment is in failure, and will be considered to be non-failure when other power equipment is accepted.

[0016] On the other hand, the present invention provides a computer storage medium having a computer program stored thereon. When the computer program is executed in a computer, the computer is caused to execute the above-mentioned one-key sequential control automatic acceptance method for a substation.

DETAILED DESCRIPTION

[0021] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0022] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0023] Example 1 To solve the above problems, according to one aspect of the present invention, Figure 1 As shown, a one-button sequential control automatic acceptance method for a substation is provided, which specifically includes: S1 performs different one-button sequential control operation types on associated power equipment using the one-button sequential control operation logic of the substation, and when it is determined based on analysis results of operation and maintenance data of different associated power equipment that the operation type requires consideration of the failure risk of the associated power equipment, proceeds to the next step; Furthermore, the associated power equipment is the power equipment involved in the operation process of the one-button sequential control operation type.

[0024] Specifically, the operation and maintenance data of the associated power equipment includes the number of risk locations of the associated power equipment and associated fault types of different risk locations.

[0025] It should be noted that the risk location is a location where the inspection data is not within the preset indicator range.

[0026] Specifically, such as Figure 2 As shown, determining the operation type requires considering the failure risk of the associated power equipment, specifically including: Determining the number of risk locations of the power equipment associated with the operation type based on operation and maintenance data of the power equipment associated with the operation type; Treat the associated power equipment in risky locations as risky power equipment; According to the number of the risky power devices, it is determined whether the operation type needs to consider the failure risk of the associated power devices.

[0027] It is understandable that when the proportion of the risky power equipment in the associated power equipment in the operation type is greater than the preset risk equipment proportion, it is determined that the operation type needs to consider the failure risk of the associated power equipment.

[0028] It should be noted that, when the operation type does not need to consider the failure risk of the associated power equipment, the failure risk of the associated power equipment does not need to be considered when performing the automatic acceptance processing of the operation type.

[0029] S2 determines associated risk faults of different associated power equipment and the determination of risk power equipment based on the analysis results of the operation and maintenance data of different associated power equipment, and determines the fault-associated power equipment of the risk power equipment based on the historical failure times of the risk power equipment under different associated risk faults and the failure data of the power equipment of the substation; Specifically, such as Figure 3 As shown, the method for determining the associated risk failure of the associated power equipment is: Determining the number of risk locations of the associated power equipment based on an analysis result of the operation and maintenance data of the associated power equipment; Based on the risk positions of the associated power devices, associated risk faults of the associated power devices are determined.

[0030] Furthermore, the associated risk fault of the associated power equipment is determined according to the fault type when an abnormality occurs at the risk location.

[0031] It should be noted that the risky power equipment is associated power equipment with associated risk failures.

[0032] In another possible embodiment, the method for determining the power equipment associated with the failure of the risky power equipment is: Determine the faulty power equipment under different historical fault times based on the fault data of the power equipment of the substation under different historical fault times of the risky power equipment; Determine the fault correlation value of the power equipment with the risk fault power equipment under different associated risk faults according to the ratio of the number of historical faults of the power equipment belonging to the fault power equipment under different associated risk faults to the number of historical faults under the associated risk faults; An average value of the correlation values between the power equipment and the risk power equipment under different associated risk faults is used to determine a mean correlation value between the power equipment and the risk power equipment, and whether the power equipment is a fault-associated power equipment is determined based on the mean correlation value.

[0033] Furthermore, when the mean value of the correlation value is greater than a preset correlation value threshold, it is determined that the power equipment is a fault-related power equipment of the risk power equipment.

[0034] In another possible embodiment, the method for determining the power equipment associated with the failure of the risky power equipment is: S201 determines the faulty power equipment under different historical fault times of the risky power equipment under different associated risk fault times based on the fault data of the power equipment of the substation; Before proceeding to the next step in the above step S201, it is also necessary to determine that when the power equipment does not belong to the faulty power equipment under different historical fault times, it is determined that the power equipment does not belong to the fault-associated power equipment of the risk power equipment. If the power equipment has a historical fault time of the faulty power equipment, the specific proportion needs to be determined.

[0035] Among them, if the proportion of the historical failure times of the power equipment belonging to the fault power equipment in the historical failure times of the risk power equipment in different associated risk failures is greater than the preset number proportion threshold, then the power equipment is determined to be a fault-associated power equipment of the risk power equipment, and only when the proportion of the historical failure times of the power equipment belonging to the fault power equipment in the historical failure times of the risk power equipment in different associated risk failures is not greater than the preset number proportion threshold, the fault association value is determined.

[0036] S202 determines the fault association value of the power equipment with the risk fault power equipment under different associated risk faults based on the ratio of the number of historical faults of the power equipment belonging to the faulty power equipment under different associated risk faults to the number of historical faults under the associated risk faults; In a possible embodiment, in the above steps, if there is an associated risk type with a fault association value greater than a preset fault association value threshold, it is determined that the power equipment belongs to the fault-associated power equipment of the risk power equipment, and only when there is no associated risk type with a fault association value greater than the preset fault association value threshold, the determination of the corrected association value is performed.

[0037] S203 determines the corrected association value of the power equipment with the risk power equipment under different associated risk faults based on the number of risk positions of the risk power equipment corresponding to different associated risk types and the fault association value of the power equipment with the risk power equipment under different associated risk faults, determines the mean association value of the power equipment with the risk power equipment based on the average value of the fault association value with the risk power equipment under different corrected risk faults, and determines whether the power equipment is a fault-associated power equipment based on the mean association value.

[0038] In step S203, the corrected association value of the power equipment with the risk-fault power equipment under different associated risk faults can be determined according to the number of risk positions of the risk power equipment corresponding to the associated risk type and the average value of the fault association value of the risk-fault power equipment.

[0039] S3 determines that when the acceptance risk of the operation type meets the requirements based on the overlapping data of the fault-associated power equipment of different risk power equipment and the associated power equipment of the operation type, the acceptance method of different associated power equipment during the acceptance processing in the operation type is determined based on the fault association situation of different associated power equipment at different risk power equipment.

[0040] Specifically, determining whether the acceptance risk of the operation type meets the requirements includes: Determining the number of overlaps between fault-associated power devices of different risky power devices and associated power devices of the operation type based on overlap data between fault-associated power devices of different risky power devices and associated power devices of the operation type; determining fault device coincidence values for different risky power devices based on a ratio of the coincidence number to the number of power devices associated with the operation type; The fault equipment overlap values of different risk power equipment are used to determine whether the acceptance risk of the operation type meets the requirements.

[0041] Furthermore, the failure coincidence values of different risk power equipment are used to determine whether the acceptance risk of the operation type meets the requirements, specifically including: When the number of risky power equipment whose faulty equipment coincidence value is greater than the preset coincidence value threshold is greater than the set value of the number of risky equipment, it is determined that the acceptance risk of the operation type does not meet the requirements.

[0042] It should be noted that when the acceptance risk of the operation type does not meet the requirements, the acceptance failure number interval is constructed using 1 to the number of associated power equipment as a constraint condition, starting with the number of failures of the associated power equipment from 1, and the acceptance failure number interval is used to determine the number of failures of the associated power equipment until all failures are detected, and automatic acceptance processing of the operation type is performed.

[0043] In another possible embodiment, determining that the acceptance risk of the operation type meets the requirements specifically includes: S301 obtains the number of risk power equipment of the operation type, and determines the number of overlaps between fault-associated power equipment of different risk power equipment and associated power equipment of the operation type based on overlap data between fault-associated power equipment of different risk power equipment and associated power equipment of the operation type; In one embodiment, step S301 includes the following three situations: Case 1: If either the number of risky power equipment of the operation type or the proportion of risky power equipment in the number of associated power equipment in the operation type does not meet the requirement, that is, is greater than the threshold, then it is determined that the acceptance risk of the operation type does not meet the requirement; Case 2: If the number of risky power equipment of the operation type and the proportion of risky power equipment in the number of associated power equipment in the operation type both meet the requirements: when the number of coincident fault-associated power equipment of different risky power equipment is less than the preset coincidence number threshold, it is determined that the acceptance risk of the operation type meets the requirements; Case 3: When there is a risk power device whose number of overlapping fault-related power equipment is not less than the preset overlapping number threshold: When there is a risk power device whose number of overlapping fault-related power equipment is within the preset overlapping equipment number interval: then it is determined that the acceptance risk of the operation type does not meet the requirements, and only when there is no risk power device whose number of overlapping fault-related power equipment is within the preset overlapping equipment number interval: go to step S302.

[0044] S302 determines the fault device coincidence value of different risk power devices based on the ratio of the coincidence number to the number of power devices associated with the operation type; It should be noted that in the above step S302, if the number of risk power equipment whose fault equipment coincidence value is greater than the preset coincidence value threshold is greater than the set value of the number of risk equipment, it can be directly determined that the acceptance risk of the operation type does not meet the requirements.

[0045] S303 determines the acceptance risk value of the operation type based on the fault equipment overlap values of different risk power equipment, and determines whether the acceptance risk of the operation type meets the requirements based on the acceptance risk value.

[0046] In a possible embodiment, the acceptance risk value is determined according to the average of the fault equipment coincidence values of different risk power equipment.

[0047] Further, when the acceptance risk value is greater than a preset acceptance risk value threshold, it is determined that the acceptance risk of the operation type does not meet the requirements.

[0048] Specifically, such as Figure 4 As shown, the method for determining the acceptance mode of the associated power equipment during the acceptance process in the operation type is: Based on the fault correlation between different associated power equipment and different risk power equipment, determine the risk power equipment associated with different associated power equipment, and use them as associated risk power equipment; The proportion of the number of risk power equipment associated with the associated power equipment in the associated power equipment of the operation type is used as the associated quantity proportion; An acceptance method for the associated power equipment during acceptance processing in the operation type is determined based on the associated quantity ratio.

[0049] Furthermore, determining an acceptance method for the associated power equipment during acceptance processing in the operation type based on the associated quantity ratio specifically includes: When the proportion of the associated number is greater than a preset threshold of the proportion of the associated number, the associated power equipment is set as faulty or non-faulty during the acceptance process in the operation type; When the proportion of the associated number is not greater than the preset threshold value of the proportion of the associated number, during the acceptance processing of the operation type, the associated power equipment will only be considered to be in failure and non-failure when its associated risk power equipment is in failure, and will be considered to be non-failure when other power equipment is accepted.
