The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a multi-set principle checking method and apparatus for fixed value online checking according to an embodiment of the present invention with reference to the accompanying drawings, and first, a multi-set principle checking method for fixed value online checking according to an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a flowchart of a multi-set principle checking method for on-line checking of fixed values according to an embodiment of the present invention.
As shown in fig. 1, the multi-set principle checking method for fixed value online checking includes the following steps:
in step S101, the device to be checked and the multiple sets of checking rule bases are associated.
Among others, in one embodiment of the present invention, the method of the present invention further comprises: and adding principles according to a standard principle library and a principle editing tool which take the industry standard as a reference, and defining different dimensions of each principle to generate a plurality of sets of checking principle libraries.
Specifically, with the construction of smart power grids, the scale of power grids is continuously enlarged, the structure of the power grids is continuously complex, and the challenges of power grid operation are continuously enhanced. The relay protection is used as a first defense line of the power grid and plays a vital role in safe operation of the power grid, so that the correctness of the relay protection setting value directly influences whether the power grid can safely and stably operate, and the method is particularly important for checking the setting value. Due to the difference of the quality and experience of relay protection personnel, the correctness of the relay protection setting value is possibly influenced; and the fixed value calculation principle of each area is specially set according to the characteristics and operation experience of the power grid of each area, and the universal industry standard is difficult to meet the fixed value calculation and check requirements.
Based on the above problems, in order to improve the adaptability and normalization of the on-line check of the fixed value to the power grids in various regions and avoid performance defects of the fixed value, the embodiment of the invention is applicable to the on-line check and early warning application of relay protection in various stages of scheduling, and can use a multi-principle library for real-time check, wherein the multi-principle library is: the method comprises the steps of uniformly checking a principle standard (industry standard) in the power industry, calculating rules of each region established by each region according to the actual condition and the calculating mode of a power grid of each region and a checking principle set according to personal experience, automatically checking a plurality of sets of checking principles by a program, and merging final results. The method provided by the embodiment of the invention can be used for checking the setting value in real time by applying a plurality of principle libraries, so that the accuracy, flexibility and practicability of checking the relay protection setting value are improved.
It can be understood that, as shown in fig. 2 and 3, the multiple sets of checking principle libraries are created based on a standard principle library based on an industry standard and a flexible principle editing tool to add principles, so as to form a new principle library, and different dimensions are defined for the principles, so as to form various dimension principle libraries, that is, multiple sets of checking principle libraries. The implementation logic is as shown in the figure.
After a standard checking principle library and multiple checking principle libraries with different dimensions are formed by the method for establishing the multiple checking principle libraries, checking of protection constant value performance is performed based on the multiple checking principle libraries, and finally a result of constant value checking and a basic suggestion of constant value adjustment are formed, which are described in detail below.
Firstly, in the embodiment of the invention, after a fixed value checking program based on a plurality of sets of checking principle libraries is started, a device to be checked and a fixed value item thereof are automatically associated with the plurality of sets of checking principle libraries to form an online checking basic model based on the plurality of sets of checking principle libraries.
In step S102, the to-be-calibrated constant value items are calibrated according to the device constant value sequence to obtain a preliminary calibration result.
Specifically, the to-be-calibrated performance is calibrated according to the device constant value item sequence, and a calibration result of the to-be-calibrated constant value item is obtained from the calibration analysis data.
In step S103, it is determined whether the preliminary check result satisfies the alarm condition.
Specifically, whether the constant value item checked according to the standard checking principle library is alarmed or not is judged. It should be noted that the alarm condition may be set by a person skilled in the art according to actual situations, and is not specifically limited herein.
In step S104, if the alarm condition is satisfied, the checking rules of different dimensions and the dimension number are obtained, the rules of the dimensions that are not checked are checked with a fixed value, and all the checking results are recorded.
That is to say, the checking principle and the dimension number of different dimensions are obtained, after the data obtaining is completed, the principle of dimension not checked is checked in a fixed value mode, and after the checking is completed, all checking results are recorded, wherein the result recording is performed for each checking of the fixed value item.
In addition, after the recording is finished, whether all the dimension principles are checked is judged, and the next step is executed after the checking is finished.
In step S105, it is determined whether any check result of all the check results satisfies the alarm condition.
That is, whether an alarm exists in the check result of the multidimensional check library is judged.
In step S106, if the checking result satisfies the alarm condition, all the alarm principles are obtained, and all the alarm principles are sorted according to the rank, so as to generate the final result of the constant value item to be checked.
In one embodiment of the present invention, generating a final result of the constant value item to be checked includes: alarming according to the highest alarm level; and generating a fixed value adjustment suggestion based on the lowest alarm level principle.
Specifically, all alarm principles are acquired and ranked according to levels, and the final result of the fixed value item is formed. For example, according to the alarm with the highest alarm level, a fixed value adjustment suggestion is formed (rule: fixed value adjustment is performed based on the principle of the lowest alarm level, if the lowest alarm level requires less than or equal to M, the adjustment suggestion is that the fixed value is adjusted to less than or equal to M).
In addition, in one embodiment of the present invention, the method further includes: if the alarm condition is not met or no check result meets the alarm condition, recording the preliminary check result as a meeting result, and setting the value adjustment suggestion as a reservation suggestion.
It is understood that the checking result is recorded as "satisfied" and the adjustment is suggested as "reserved".
Further, in an embodiment of the present invention, the method further includes: judging whether all the constant value item checking is finished or not; and if all the fixed value items are checked, finishing the checking process of the multiple sets of checking principle libraries, and displaying the final result according to the preset program display strategy.
Specifically, whether all the fixed value item checking is finished or not is judged, and after all the fixed value item checking is finished, the checking process of the multiple sets of checking principle libraries is finished, and the result is displayed according to the program display mode. It should be noted that the preset program display policy exhibition can be set by a person skilled in the art according to actual situations, and is not specifically limited herein.
In summary, with the construction of smart power grids, the scale of the power grid is continuously enlarged, the structure of the power grid is continuously complex, and the challenge of power grid operation is continuously enhanced. The relay protection is used as a first defense line of the power grid and plays a vital role in safe operation of the power grid, so that the correctness of the relay protection setting value directly influences whether the power grid can safely and stably operate, and the method is particularly important for checking the setting value. Due to the difference of the quality and experience of relay protection personnel, the correctness of the relay protection setting value is possibly influenced; and the fixed value calculation principle of each area is specially set according to the characteristics and operation experience of the power grid of each area, and the universal industry standard is difficult to meet the fixed value calculation and check requirements. In order to improve the adaptability and the normalization of the on-line check of the fixed value to each regional power grid and avoid the performance defect of the fixed value, the embodiment of the invention provides a multi-set principle check method for the on-line check of the fixed value, which is suitable for the on-line check and the early warning application of relay protection of each-level scheduling, and the on-line check can be performed by using a multi-principle library for real-time check, wherein the multi-principle library refers to: the method comprises the steps of uniformly checking a principle standard (industry standard) in the power industry, calculating rules of each region established by each region according to the actual condition and the calculating mode of a power grid of each region and a checking principle set according to personal experience, automatically checking a plurality of sets of checking principles by a program, and merging final results.
