Description

Technical Field

[0001] The present invention relates to the technical field of substation management, and in particular to a monitoring method and system for preventing mislocking of a substation. Background Art

[0002] The purpose of the monitoring method and system for preventing mislocking of a substation is to prevent mislocking events and ensure the correct operation of power equipment and the safety of the power system. In the prior art, in order to prevent the harm caused by mislocking, it is necessary to monitor the locking action in real time. The conventional monitoring method is to directly monitor the difference between the locking action of a single locking task and the standard locking logic. Although this method can determine the error of the locking action, it cannot determine the characteristics of the locking error, and thus cannot judge the damage caused by the error of the locking action. Therefore, there is an urgent need for a monitoring method and system for preventing mislocking that can judge the state of the mislocking action. Summary of the invention

[0061] In the second step, based on the abnormality evaluation of the second current locking logic mapping structure, a second state result of the locking action corresponding to the second current locking logic mapping structure is determined.

[0062] In some embodiments of the present application, a method for evaluating an abnormality of a second current blocking logic mapping structure includes:

[0063] In the first step, based on the locking task requirements corresponding to the second current locking logic mapping structure, a corresponding standard locking logic mapping structure is selected, and the structural difference blocks of the standard locking logic mapping structure and the second current locking logic mapping structure are compared and analyzed.

[0064] In the second step, the locking node corresponding to the structural difference block is determined on the standard locking logic mapping structure and recorded as the first abnormal locking node.

[0065] The third step is to determine the abnormal characteristic parameter of the first abnormal locking node based on the locking requirement information corresponding to the first abnormal locking node.

Then, conduct comparative analysis to compare the structural difference blocks between the standard locking logic mapping structure and the second current locking logic mapping structure.

[0069] The second step is to determine the abnormal locking nodes: on the standard locking logic mapping structure, determine the locking nodes corresponding to the structural difference blocks, and mark these nodes as the first abnormal locking nodes. These nodes are the key nodes that cause operation abnormalities.

[0070] The third step is to determine the abnormal characteristic parameters: based on the locking requirement information corresponding to the first abnormal locking node, determine the abnormal characteristic parameters of the first abnormal locking node, and the abnormal characteristic parameters describe the reference quantities of different abnormal factors of the abnormal node.

[0071] The fourth step is to determine the abnormality evaluation: based on the abnormal number and abnormal characteristic parameters of the first abnormal locking node corresponding to the structural difference block, determine the abnormality evaluation of the second current locking logic mapping structure.

[0072] In some embodiments of the present application, the expression of the abnormal evaluation of the second current locking logic mapping structure is:

[0073]

[0074] Among them, p is the abnormal evaluation of the second current blocking logic mapping structure, x is the abnormal number of the first abnormal blocking node corresponding to the structural difference block, b1 is the abnormal number adjustment constant, t n is the abnormal characteristic parameter of the nth first abnormal closed node corresponding to the structural difference block, and k1 is the abnormal evaluation conversion coefficient.

[0075] In some embodiments of the present application, a method for classifying past lockout logic mapping structures based on comparison analysis results and past hazard records to generate several categories of lockout logic mapping structure data sets includes:

[0076] The first step is to determine the structural difference characteristics between the past locking logic mapping structure and the standard locking logic mapping structure, and associate the structural difference characteristics with the hazard record.

If the overall hazard value corresponding to the structural difference feature belongs to the second preset hazard value interval, the locking action corresponding to the past locking logic mapping structure is deemed qualified. If the overall hazard value corresponding to the structural difference feature belongs to the third preset hazard value interval, the locking action corresponding to the past locking logic mapping structure is deemed abnormal.

[0079] In the fourth step, the past locking logic mapping structure is classified based on three categories: normal locking action, qualified locking action and abnormal locking action.

[0080] In some embodiments of the present application, the hazard factors in the hazard record include: power system interruption, equipment damage degree, power quality impact and safety risk degree.

[0084] In the second step, each past locking logic mapping structure in each locking logic mapping structure data set is scanned sequentially in a single direction, and the second sub-logic mapping structure of each scan is recorded according to a preset scanning sequence number.

[0085] The third step is to screen the past locking logic mapping structure according to the adaptability of the first sub-logic mapping structure and the second sub-logic mapping structure. If the screened past locking logic mapping structure is not unique, continue scanning to expand the scale of the first sub-logic mapping structure and the second sub-logic mapping structure, and screen the past locking logic mapping structure by comparing the two until the screened past locking logic mapping structure is unique.

[0086] The fourth step is to completely compare and analyze the unique past locking logic mapping structure and the first current locking logic mapping structure. If the two structures are identical, the calibrated state characteristics of the category locking logic mapping structure data set to which the past locking logic mapping structure belongs are determined to be the first state result of the locking action corresponding to the first current locking logic mapping structure.

[0087] In some embodiments of the present application, a monitoring system for preventing mislocking of a substation is also disclosed, comprising: a lock mapping graph generation module, a reference data set generation module and a comparison and analysis module.
