The method comprises the steps of acquiring first protection action data acquired by an intelligent oscillograph and second protection action data acquired by a protection device corresponding to a protection action according to the occurrence of the protection action, respectively acquiring a first analysis result and a second analysis result through analysis of the first protection action data and the second protection action data, determining actual numerical value information of an electric power system when the protection action is generated based on the first analysis result and the second analysis result, automatically acquiring target fixed value information corresponding to the protection action according to a protection logic diagram corresponding to the protection device, and acquiring a protection action analysis result through matching the actual numerical value information and the target fixed value information. And generating a protection action time sequence chart based on the first protection action data, and combining the protection action analysis result and the protection action time sequence chart to generate a protection action comprehensive evaluation report corresponding to the target time range.
In one embodiment, as shown in fig. 2, a protection action analysis method is provided, which is described by taking the method as an example applied to the power system in fig. 1, and includes the following steps:
Specifically, the protection device generates corresponding protection actions when judging that a fault occurs according to the operation condition of each line of the power system, and one or more protection actions can occur sequentially or simultaneously. Protection actions are classified into various types, including differential Protection (PDIF), distance Protection (PDIS), zero sequence overcurrent Protection (PTOC), automatic reclosing (RREC), and the like. The target time range is the time range corresponding to the whole stage before the fault occurs and after the fault occurs, and the corresponding target time range can be determined by detecting the starting time of the protection period and the ending time of the fault. The target time range is used for setting a time period in the intelligent wave recorder to carry out accurate search, so that the information related to the protection action is obtained, and the irrelevant information is eliminated.
The first protection action data comprises an information table and a wave recording file, wherein the information table is used for recording protection starting time, protection action occurrence time, protection action elements, tripping/closing and contact point reverse correction messages, switch deflection information, alarm information and the like. Any one of the types of protective actions may be referred to as a protective action element. The protection operation sequence chart is a schematic diagram generated in chronological order from the power system-related lines and devices involved in the protection operation in the implementation process.
Specifically, intelligent substation itself disposes intelligent oscillograph, and process level network and station accuse layer network have been inserted simultaneously to intelligent oscillograph, and is multiple information, possesses information integration's function. The intelligent wave recorder can automatically record all information of the whole station, and aiming at one or more protection actions corresponding to the current protection, the protection is selected in the intelligent wave recorder according to the action time recorded by the protection, and then the target time range is set in the intelligent wave recorder for accurate search by combining the action time of the protection action element, so that the information related to the protection is obtained, and the irrelevant information is eliminated. In one embodiment, the protection starting time, the time when the protection action occurs, the protection action element, the tripping/closing and contact reverse correction messages, the switch deflection information and the alarm information automatically generate a protection action time sequence diagram, wherein the reverse correction messages and the alarm information are optional contents for generating the protection action time sequence diagram. In one embodiment, a timing diagram of the protection actions generated is shown in FIG. 3. For the first protection action data analysis, different analysis methods can be adopted to obtain each sub-analysis result, and each sub-analysis result forms a first analysis result. The waveform change of the fault voltage and the current can be checked through a recording waveform analysis tool, and analysis sub-results corresponding to different analysis methods before and after the fault are generated.

The analysis methods and dimensions corresponding to the first analysis result and the second analysis result are consistent, and subsequent comparison is convenient. When the first analysis result is consistent with the second analysis result, the actual numerical information can be any one of the analysis results, when the first analysis result is inconsistent with the second analysis result, one of the more reliable results can be selected as the actual numerical information through an algorithm, and each analysis result can be used as the actual numerical information to enter the following steps for processing, so that the completeness of the analysis is ensured.
And 208, acquiring a protection logic diagram corresponding to the protection device, determining a corresponding protection action logic condition according to the protection logic diagram, and determining target fixed value information corresponding to the protection action according to the protection action logic condition.
Specifically, the models of different protection devices correspond to different protection logic diagrams, and the models of the protection devices are determined, so that the corresponding protection logic diagrams are obtained. The protection logic diagram includes "differential Protection (PDIF)", "distance Protection (PDIS)", "zero sequence over current Protection (PTOC)", and "automatic reclosing (RREC)", etc., and all necessary conditions of the protection action are identified one by one from the protection logic diagram, for example: line differential protection can recognize three conditions from the protection logic diagram: 1) protection starting, 2) the differential current reaches an action fixed value, 3) a line-opposite differential action permission signal is received. After the logic condition of the protection action is identified, the electronic fixed value list corresponding to the protection is imported, and the target fixed value information related to the protection action is automatically matched.
And step 210, correspondingly matching the actual numerical value information with the target fixed value information, and generating a protection action analysis result according to the matching result.
Specifically, the actual numerical value information is the actual performance value when the fault occurs, these values are compared with the corresponding items in the target constant value information to determine whether the protection action is correct, and the logic condition of the protection action identified in the protection logic diagram determines the constant value item to be compared.
Automatically judging whether the protection action is correct or not, if so, generating a protection action analysis result, entering the next step, if not, screening out the specific protection action logic conditions which are not satisfied, including the fixed value items which are not satisfied, then generating a corresponding protection action analysis result, and entering the next step.
And step 212, combining the protection action analysis result and the protection action sequence chart to generate a protection action comprehensive evaluation report corresponding to the target time range.
Specifically, a protection action time sequence diagram in the target time range and the protection action analysis results of all the protection devices in the target time range are combined to generate a protection action comprehensive evaluation report corresponding to the target time range.

In one embodiment, the first analysis result and the second analysis result respectively include at least one of a phasor analysis result, a sequence component analysis result, and an impedance analysis result, and the determining the actual numerical information based on the first analysis result and the second analysis result in step 206 includes: and comparing the same type of analysis results in the first analysis result and the second analysis result respectively, and taking the information in the first analysis result or the second analysis result as actual numerical information when the comparison results corresponding to the analysis results are consistent.
Specifically, the protection device and the intelligent wave recorder generate respective wave recording files during protection action, at least one analysis result of a phasor analysis result, a sequence component analysis result and an impedance analysis result is obtained through analysis of the respective wave recording files, wherein the first analysis result comprises at least one analysis result of a first phasor analysis result, a first sequence component analysis result and a first impedance analysis result, the second analysis result comprises at least one analysis result of a second phasor analysis result, a second sequence component analysis result and a second impedance analysis result, the same type of analysis results are compared, for example, the first phasor analysis result is compared with the second phasor analysis result, the first sequence component analysis result is compared with the second sequence component analysis result, and the first impedance analysis result is compared with the second impedance analysis result, and when all the analysis results of the same type in the first analysis result and the second analysis result are consistent, selecting one of the first analysis result and the second analysis result as the subsequent analysis for use as the actual numerical information.
In this embodiment, whether the first analysis result is consistent with the second analysis result is determined by comparing the analysis results of a plurality of different dimensions, and if so, only the content in any one of the analysis results needs to be selected as the actual numerical information, thereby avoiding repeated operation when the two analysis results are consistent.
In one embodiment, the method further comprises: and when the inconsistent comparison results exist, taking the first analysis result as first actual numerical value information, and taking the second analysis result as second actual numerical value information. Step 210 comprises: correspondingly matching the first actual numerical value information with the target fixed value information, and generating a first protection action analysis sub-result according to a matching result; correspondingly matching the second actual numerical value information with the target fixed value information, and generating a second protection action analysis sub-result according to a matching result; and generating a protection action analysis result by combining the first protection action analysis sub-result and the second protection action analysis sub-result.
Specifically, if the comparison results are inconsistent, the analysis results respectively corresponding to the two recording files are independently supplied to the subsequent steps for continuous use, so that two corresponding protection action analysis sub-results are respectively obtained according to the two analysis results, two protection action judgment conclusions are obtained, and the protection action analysis results are generated by combination. Respectively obtaining first actual numerical value information and second actual numerical value information, correspondingly matching the first actual numerical value information and the target fixed value information during subsequent comparison, and generating a first protection action analysis sub-result according to a matching result; and correspondingly matching the second actual numerical value information with the target fixed value information, generating a second protection action analysis sub-result according to the matching result, and combining to generate a protection action analysis result. It can be understood that the first protection action analysis sub-result and the second protection action analysis sub-result may be the same or partially the same, or completely different, for example, the first protection action analysis sub-result is a protection action correct, and the second protection action analysis sub-result is also a protection action correct. When a fault corresponds to multiple protection actions, the first protection action analysis sub-result may be that the a protection action is correct and the B protection action is wrong, and the second protection action analysis sub-result may be that the a protection action is wrong and the B protection action is wrong.
In this embodiment, when inconsistent comparison results exist, corresponding protection action analysis sub-results are respectively obtained according to each analysis result, so that a plurality of different recording files are considered in the protection action analysis results, and the comprehensiveness and reliability of the analysis results are ensured.
In one embodiment, the method further comprises: obtaining all inconsistent comparison results to form comparison evaluation contents; and writing the comparison evaluation content into a comprehensive evaluation report of the protection action.

In one embodiment, step 208 includes: determining a protection action logic condition corresponding to a protection action from the protection logic diagram; acquiring a fixed value list corresponding to a protection action, and matching the fixed value list based on a logic condition of the protection action to obtain a target fixed value item corresponding to the protection action and a corresponding target value; and target constant value information is formed by target values corresponding to all the target constant value items.
Specifically, after the protection action occurs, whether element actions such as overcurrent, overvoltage protection, differential protection, distance protection and the like are correct or not needs to be analyzed by combining a recording file, the basis for judging whether the actions are correct or not is yes, a waveform analysis result is compared with protection action logic conditions corresponding to a protection device, and if all conditions of the protection action are met in the waveform analysis result, the protection correct action is judged. For example: the protection action logic conditions of the line differential protection action are as follows: 1) protection starting, 2) the differential current reaches an action fixed value, 3) a line-opposite differential action permission signal is received. If the three conditions are satisfied after the waveform analysis, the protection is determined to be correct. The target constant value item and the corresponding target value corresponding to each protection action logic condition are obtained from the constant value list, the target value corresponding to each target constant value item constitutes target constant value information, in the above example, the differential current is the target constant value item, and the action constant value is the target value corresponding to the differential current. And the protection action can be judged to be correct only if the target values corresponding to the target constant value items are met.
In the embodiment, all necessary conditions of the protection action, namely the logic conditions of the protection action, are identified one by one according to the protection logic diagram, the logic conditions of the protection action are imported into the electronic fixed value list corresponding to the protection, and the target fixed value items related to the protection action are automatically matched to obtain the corresponding target value, so that whether the protection action element acts correctly or not can be judged by combining the wave recording file analysis result, the protection logic diagram and the fixed value list, the whole process does not need manual participation, and the method is convenient and efficient.

And if the wave recording analysis results are consistent, selecting one analysis result to enter the next step, and if the wave recording analysis results are inconsistent, independently entering the next step by using the two analysis results and simultaneously generating an inconsistent report.

And when the two analysis results are inconsistent, automatically identifying inconsistent information, and independently entering the next analysis. And identifying all necessary conditions of the protection action one by one according to the protection logic diagram, automatically matching the fixed value items related to the protection action according to the imported electronic fixed value list corresponding to the protection, and judging whether the protection action element acts correctly or not by combining the wave recording file analysis result, the protection logic diagram and the electronic fixed value list. If the protection is judged to be incorrect, specific conditions which are not met are automatically given, comprehensive analysis is carried out according to the protection action time sequence and the action behaviors of the protection action elements, comprehensive evaluation of the protection action is given, the whole process is full-automatic, manual participation is not needed, and the analysis efficiency of the protection action is greatly improved.
