Description

Technical Field

[0001] This invention belongs to the field of power system digital technology, and relates to a digital operation system and method for fine evaluation of substation equipment. Background Technology

[0002] Substations have a large number of devices. Conducting scientific and reasonable condition assessments of their health and operating status can improve the comprehensive analysis and refined management of the equipment. This provides strong decision support for the rational arrangement of equipment operation and maintenance, the formulation of power grid risk control strategies and dispatch plans, thereby ensuring system safety and power supply reliability, and creating more economic and social benefits for the power grid.

[0003] Typically, substation equipment status is evaluated based on a weighted average of various evaluation indicators, categorized into four states: "Normal," "Attention," "Abnormal," and "Severe," corresponding to four levels: A, B, C, and D. The refined evaluation process builds upon the equipment status evaluation results. Within a defined system of refined evaluation status variables, it assesses the fulfillment of these variables, further subdividing the four status levels to obtain the refined evaluation level results. The refined evaluation result is the cumulative decrease in level caused by each characteristic status variable. Based on the final refined level results, the substation can develop corresponding operation and maintenance strategies for the relevant equipment.

[0004] Currently, detailed evaluation of substations mainly relies on a manual process. This involves collecting and verifying data, adjusting the equipment condition assessment level based on the equipment condition assessment list, and making a comprehensive judgment. This process relies on professional maintenance personnel to compile and evaluate a large amount of statistical data on paper. This manual approach is inefficient, makes effective comparison difficult, lacks statistical analysis capabilities, and makes it hard to guarantee the accuracy and validity of the detailed equipment condition evaluation results.

[0053] Figure 1 is the fine evaluation digital operation system architecture and flowchart of the application. DETAILED DESCRIPTION

[0054] The application will be further described below in combination with the drawings. The following examples are only used to more clearly illustrate the technical solutions of the application, and cannot be used to limit the protection scope of the application.

[0055] As shown in Figure 1 , the embodiment 1 of the application provides a fine evaluation digital operation system of substation equipment, which comprises the following modules:

[0056] A. fine evaluation project initiation module;

[0057] B. fine evaluation project development module;

[0058] C. fine evaluation project treatment module.

[0059] In the preferred but non-limiting embodiments of the application, the implementation schemes of the modules are as follows:

[0060] A. fine evaluation project initiation module

[0061] The fine evaluation project initiation module: mainly initiates the fine evaluation project plan according to the demand of annual fine evaluation work, selects the equipment to be evaluated, formulates different equipment characteristic state quantities, regulation rules, and determines the grade standard of subsequent treatment.

[0062] Further preferably, the fine evaluation project initiation module comprises the following units:

[0063] (1) fine evaluation project plan initiation unit:

[0064] The fine evaluation project plan includes the fine evaluation project name and the project evaluation start and end time.

[0065] (2) to-be-evaluated equipment selection unit:

[0066] Mainly provide a one-key selection function, after selecting all kinds of this time fine evaluation project, the digital operation system will automatically synchronize all the equipment under the corresponding category in the production system to the to-be-evaluated equipment list of the digital operation system.

[0067] The to-be-evaluated equipment list supports manual modification, addition and deletion functions, and for equipment that is not in the production system but needs to carry out fine evaluation, the addition function can be used for supplementation.

[0068] The specific synchronization mode is:

[0069] The synchronization rules including synchronization period, synchronization time and synchronization equipment type are configured, according to the synchronization rules, the fine evaluation project corresponding account data is read from the data platform through the RESTful mode and data cleaning is carried out, the cleaned data is stored in the local MySql database, and the latest account data is output to the to-be-evaluated equipment list.

[0070] (3) Characteristic state quantity formulation unit:

[0071] Different equipment characteristic state quantity formulation: according to the equipment operation experience, the operation life, the domestic defects and failures, the suspected family defects and other factors are selected to formulate the corresponding equipment state quantity for specific equipment type, such as one state quantity of alternating current transformer type is "ratio does not meet the requirements of countermeasures". One state quantity corresponds to a state quantity number.

[0072] The above-mentioned domestic defects and failures represent the state quantity summarized according to the domestic defects, failures, hidden dangers and the like, for example, for the phase modifier, the equipment with abnormal monitoring data has a failure hidden danger, and the risk of continuous operation is large, therefore, the corresponding state quantity is set: "local emission signal, shaft voltage, vibration, temperature anomaly".

[0073] The suspected family defect is that the manufacturer has a serious failure or defect in a batch / type product within five years, which indicates that the manufacturer does not strictly control the quality of the product, and this problem may also exist in the same batch / type product, and there is a family defect, therefore, the state quantity is set: "serious failure has occurred in the same batch product within five years".

[0074] In the application, different numbered equipment of the same type needs to be evaluated under the same state evaluation template, the state quantity number is composed of English letters + numbers, and the English letters can be selected as the pinyin abbreviation of the equipment type. For example, the state quantity of the transformer: put into operation for more than 5 years, which can be set as byq001.

[0075] (4) File rule formulation unit:

[0076] The fine evaluation file is adjusted according to the initial state file level of the equipment, and the corresponding fine file level is adjusted after meeting the specific characteristic state quantity of the equipment, as shown in Table 1.

[0077] Table 1 Adjustment of state quantity file level of certain equipment

[0078]

[0079] That is, when the state quantity is met, the file level is lowered, but the number of file levels to be lowered needs to be lowered according to the file adjustment rules shown in Table 1.

[0080] Further, the number of file levels to be lowered is the number of fine file levels (such as ABCD fine is A, A-, B+, B, B-, C+, C, C-, D+, D, D-).

[0081] (5) Governance file level standard determination unit:

[0082] Determine the file level standard of subsequent management: the digital operation system provides a selectable file level of the equipment that needs to be managed subsequently according to the fine evaluation file level result, specifically, some file level equipment needs to be managed, and some file level equipment needs to be differentiated.

[0083] B. Fine evaluation project development module

[0084] The fine evaluation project is developed by using the digital operation system of the application, and mainly includes the following steps:

[0085] Generation of equipment state evaluation template;

[0086] Evaluation of equipment characteristic state;

[0087] Calculation of fine file level of equipment;

[0088] Review of evaluation and calculation results.

[0089] Further preferably, the fine evaluation project development module includes the following units:

[0090] (1) Equipment state evaluation template generation unit:

[0091] According to the list of equipment to be evaluated generated in (2) of A and the characteristic state quantity prepared in (3), the system generates a corresponding equipment state evaluation template.

[0092] Each type of equipment corresponds to an equipment state evaluation template, which includes the basic information of the equipment and all state quantities under this type of equipment, state quantity evaluation results, and fine file level calculation results, wherein the basic information of the equipment and all state quantities under this type of equipment are shown in Table 2.

[0093] Table 2 Basic information of equipment in state evaluation template and all state quantities under this type of equipment

[0094]

[0095] (2) Equipment characteristic state evaluation unit:

[0096] Automatically or manually evaluate whether the specific numbered equipment meets the state quantity, and set evaluation output for each state quantity: state quantity meets value Z and adjustment value P; wherein the state quantity meets value is a binary number, Z takes 1 when the state quantity meets, otherwise takes 0; the adjustment value P is the number of downslide grades corresponding to the state quantity, which is determined according to the adjustment rule.

[0097] Automatic evaluation refers to that the system can automatically evaluate objective state quantities such as whether the equipment has been in operation for more than 5 years, whether it has ever been returned to the factory for repair, and whether it uses a certain type of product.

[0098] Manual evaluation should be carried out for subjective state quantities such as whether the equipment has not taken any treatment measures and whether it is suspected to have defects, and whether the state quantity meets the evaluation should be filled in manually by the on-site responsible personnel.

[0099] For example, in the calculation of the operation time, the system extracts the factory time field (s) of each numbered equipment in the database, and when calculating the operation time (t), the system calculates the operation time t = f-s according to the project evaluation time f. When t is less than the required year of the state quantity (5 years), the state quantity does not meet, Z = 0, and when t is greater than or equal to the required year of the state quantity (5 years), the state quantity meets, Z = 1.

[0100] Taking the transformer numbered S101 as an example, its operation time is June 1, 2015, and the state quantity number of the operation time is byq001. The adjustment rule of this characteristic state quantity is: if the operation time exceeds 5 years, it needs to be downslide by 1 grade. Therefore, when carrying out the fine evaluation in 2021, the automatic evaluation of the byq001 state quantity of this transformer is as follows: t = 2021-12-31-2015-06-01 = 2405 days, t > 1825 (5 years), output Z = 1, P = 1.

[0101] The calculation of the state quantity "whether it uses a certain type of product" is to match whether the production manufacturer field of the corresponding equipment is the same as the manufacturer modular field data set for the state quantity. If they are the same, Z = 1, otherwise, Z = 0.

[0102] The evaluation result (yes / no) of each state quantity is displayed correspondingly in the state evaluation template.

[0103] When the evaluation of a certain state quantity is carried out within the current evaluation project start and end time, the digital operation system automatically presents the feature state quantity evaluation and grade calculation results in the last evaluation period, which facilitates comparison. When the field personnel fill in the state, the corresponding supplementary explanation should be carried out (text or attachment form explanation of the device state column of the state change in the last evaluation period, faults, defects, hidden dangers, etc. occurred this year).

[0104] (3) Equipment fine grade calculation unit:

[0105] The feature state evaluation results from B (2) are further subdivided into grades according to the grading rules formulated in A (4), and the number of downslide grades is the number of subdivided grades.

[0106] The initial grade of fine evaluation has only four state evaluation grades ABCD, and the state evaluation and the fine evaluation of the application have differences. The state evaluation result is ABCD four grades, which is artificially pre-set; the fine evaluation is further evaluated by the application to obtain fine evaluation grades such as A, A-, B+, B, B-, C+, C, C-, D+, D, and D-.

[0107] The fine grade of the equipment meeting the normal operation is A.

[0108] When the same equipment meets multiple feature state quantity downslide grades, the grades need to be added up, specifically:

[0109] In the equipment fine grade calculation unit, the equipment fine grade is set to A, A-, B+, B, B-, C+, C, C-, D+, D, D- a total of 11 grades, and the grade space subset K is defined. In the grade space subset K, the serial numbers of the above fine grades are set as follows: A=1, A-=2, B+=3, B=4, B-=5, C+=6, C=7, C-=8, D+=9, D=10, and D-=11.

[0110] The initial state grade of a certain equipment is matched with the grade in the grade space subset, and the corresponding grade serial number m0 is assigned:

[0111] When the initial state grade is A, m0 is assigned 1, when the initial state grade is B, m0 is assigned 4, when the initial state grade is C, m0 is assigned 7, and when the initial state grade is D, m0 is assigned 10.

[0112] When a certain equipment meets multiple different state quantities, the fine evaluation grading calculation is carried out according to the following formula:

[0113]

[0114] In the formula, Δm is the grade adjustment amount, n is the number of state quantities of the corresponding equipment, Z iThe value of the i-th state quantity satisfies, P i The number of downshift gears corresponding to the i-th state quantity;

[0115] The fine evaluation value of the specific numbered equipment is:

[0116] The fine evaluation value is searched and matched in the gear level space subset K, and the gear level result obtained by the matching is the fine gear level calculation result obtained by the fine gear level calculation unit.

[0117] (4) Evaluation and calculation result auditing unit:

[0118] The state quantity evaluation and fine gear level calculation result are filled into the equipment state evaluation template as the final fine evaluation result of the equipment.

[0119] C. Fine evaluation project management module

[0120] The fine evaluation project management module: mainly provides a closed-loop management module for some gear level equipment according to the fine gear level calculation result of the equipment in B.

[0121] Further preferably, for some gear level equipment (such as C+, C, C-, D+, D, D-), the engineering and operation personnel need to carry out management on these equipment, fill in the management plan, management time, management means and management result in the management module.

[0122] For some gear level equipment (such as B+, B, B-), the engineering and operation personnel carry out differential operation on these equipment, and fill in the differential operation plan and the like in the management module.

[0123] The system of the present application has the functions of fine evaluation digital operation and statistical analysis display module:

[0124] (1) Overall display unit:

[0125] The type, quantity and state quantity setting number of the equipment to be evaluated (including comparison between this evaluation period and the last evaluation period).

[0126] (2) Evaluation result distribution unit:

[0127] The number of equipment of different gear levels in each unit is displayed.

[0128] (3) Equipment distribution unit:

[0129] The distribution of some gear level equipment:

[0130] The number of all devices under the file level, the number and proportion of each unit, and the number of different types of devices under the specific unit and the determined file level are included.

[0131] (4) Device management and suggestion display unit:

[0132] The type and number of devices for carrying out management, the total number of management plans, the completion of management, and the total number of suggestions are displayed.

[0133] The substation equipment fine evaluation digital operation method of the application comprises the following steps:

[0134] Step 1, according to the demand of annual fine evaluation work, the fine evaluation project plan is initiated by the fine evaluation project initiation module, the equipment to be evaluated is selected, the different equipment characteristic state quantity and the adjustment file rule are formulated, and the file level standard of subsequent management is determined;

[0135] The fine evaluation operation person (X) logs in the fine evaluation digital operation system of the application to initiate the fine evaluation project plan. Specifically, it includes:

[0136] Formulate the fine evaluation project name and project evaluation start and end time;

[0137] According to the type of the equipment to be evaluated in this evaluation work, the application system will synchronize the basic data of all types of equipment from the production operation system, including production / operation time, manufacturer, number, etc.;

[0138] Formulate the characteristic state quantity of different equipment;

[0139] Formulate the adjustment file rule.

[0140] Step 2, the equipment state evaluation template generation, equipment characteristic state evaluation, equipment fine file level calculation and evaluation and calculation result auditing are carried out by the fine evaluation project development module;

[0141] The system automatically generates the equipment state evaluation template, and the on-site operation specialist (Y) logs in the fine evaluation digital system to carry out the equipment state fine evaluation.

[0142] Specifically, it includes:

[0143] Equipment characteristic state evaluation: the system automatically associates and evaluates whether the objective state quantity meets the requirement; Y manually fills in whether the subjective state quantity meets the requirement. When evaluating the characteristic state quantity, the system automatically presents the characteristic state quantity evaluation and file level calculation result in the previous evaluation period for comparison. When Y fills in the state, the corresponding supplementary explanation (text or attachment form explanation of the state change in the previous evaluation period, this year's fault, defect, hidden danger, etc.) should be carried out.

[0144] Device fine grade calculation: the system is based on the evaluation results of the device characteristic state, and further fine grade calculation is carried out according to the formulated grade regulation. When the same device meets multiple characteristic state quantities, the grade needs to be accumulated. For example, when the transformer of the device numbered S101 in Table 2 is finely evaluated, the initial state is A, has been running for 6 years (satisfying the byq001 state quantity), and a product of a certain company has been used (satisfying the byq002 state quantity). According to the grade regulation in Table 1, when the byq001 state quantity is satisfied, the grade needs to be lowered by 1 grade, and when the byq002 state quantity is satisfied, the grade needs to be lowered by 2 grades. Therefore, when the initial state grade of the transformer numbered S101 is A, a total of 3 grades need to be lowered, and according to the lowering regulation of A, A-, B+, B, B-, C+, C, C-, D+, D, D-, the fine evaluation grade is B.

[0145] Evaluation and calculation result review: X reviews the satisfaction of the device state characteristic quantity and the calculation result of the grade, and if the review is passed, the state quantity evaluation and the fine grade calculation result are filled into the device state evaluation template as the final fine evaluation result of the device. The result that does not pass the review will be returned, and Y will redevelop the state evaluation.

[0146] Step 3, according to the fine evaluation project management module, the fine evaluation grade calculation result of the device fine evaluation project development module is provided for the closed-loop management module of the device of different grades, so that the engineering operation personnel can carry out management or operation and fill in the related information.

[0147] According to the fine evaluation grade calculation result, the system provides a closed-loop management module for some grade devices. For some grade devices (such as C+, C, C-, D+, D, D-), Y needs to carry out management, fill in the management plan, management time, management means and management result in the management module. For some grade devices (such as B+, B, B-), Y carries out differentiated operation suggestions and fills in them.
