Abstract

The invention relates to an independent analysis method for transformer monitoring fault signals based on a fault tree. According to the technical characteristics, the independent analysis method comprises the following steps: performing butt jointing on topology graphics of primary power equipment and secondary power equipment to obtain the topology connection relations and electrical property of the power equipment; defining the equipment faults and fault contents, establishing a fault library and determining fault tree rules; drawing fault tree graphics based on the wiring layout connection types of the primary power equipment and secondary power equipment; and comparing with the fault tree rules and positioning fault occurring sources.

Step 3, according to first and second equipment winding diagram connected mode, draw fault tree figure;
Step 4, comparison fault tree rule, localizing faults occurring source.
Further, described step 1, when obtaining power equipment topological connection relation and electric attribute, needs combing power equipment topological connection relation and sets up logic association and the restriction relation of electric attribute.
Further, described fault database comprises the concrete detailed content of equipment fault and fault correlation cluster tool; The method for building up of described fault database is: by defining fault impact scope delineation fault effects region, obtain electric logic relation by current operating environment attribute; Region and signal currency is involved by faulty equipment.
Further, the method for described establishment fault tree rule is: prefabricated equipment fault category, according to the policy development fault tree rule of top event-intermediate event-bottom event.
Further, the concrete methods of realizing of described step 4 is: by fault-signal via fault database iterative analysis, clear failure signal top event defect content, and the intermediate event defect content under enumerating top event; The defect content of top event and intermediate event is reflected to fault tree come up, by means of group first and second power equipment graphic topological relationship and current electric attribute value, approaches bottom event fault occurring source in fault tree.。
Advantage of the present invention and good effect are:
The present invention is to draw fault tree for analysis means, by docking first and second power equipment topological graph and using tree-shaped logic causality to be connected by the various possible factors of the system failure, the fault source of initiating failure is independently analyzed with the design sketch intuitively shown, achieve the function of quick position fault, avoid the subjectivity of dispatcher's fault location, improve the promptness of failure response.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described:
Based on an autonomous analytical method for the supervisory control of substation fault-signal of fault tree, as shown in Figure 1, comprise the following steps:
Step 1, dock first and second power equipment topological graph, obtain the electric attribute of power equipment topological connection relation and current power equipment;
In this step, in order to review the final fault source with localizing faults equipment, need docking one, two power equipment wiring figure, obtain power equipment topological connection relation, and read current electric equipment electric logic data in real time, the topological connection relation of combing power equipment, sets up logic association and the restriction relation of electric signal.
Step 2, define equipment fault and defect content, set up fault database, establishes fault tree rule;
In this step, by current failure signal typing fault database, obtain the event of failure with topological relation under the coverage of fault-signal, event of failure is contrasted fault tree rule, obtain the logical relation of event of failure.
Fault database comprises the concrete detailed content of equipment fault and fault correlation cluster tool.By defining fault impact scope delineation fault effects region, obtain electric logic relation by current operating environment attribute; Involve region and signal currency by faulty equipment, first obtain fault-signal characterization information, secondly the influencing factor of analysis of failure sign, last resultant fault influencing factor investigation bottom event of failure.
When establishing fault tree rule, prefabricated equipment fault category, according to the policy development fault tree rule of " top event-intermediate event-bottom event ".
Step 3, according to first and second equipment winding diagram connected mode, draw fault tree figure;
In this step, obtain the topological structure of event of failure according to first and second power equipment topological graph, draw fault tree figure.
Step 4, comparison fault tree rule, localizing faults occurring source.
In this step, according to fault tree rule, on the basis that event of failure logic association is analyzed, realize the bed-by-bed analysis of fault top event, intermediate event, obtain the bottom event of initiating failure, clear failure source.Concrete grammar is: by fault-signal via fault database iterative analysis, clear failure signal top event defect content, and the intermediate event defect content under enumerating top event; The defect content of top event and intermediate event is reflected to fault tree come up, by means of group first and second power equipment graphic topological relationship and current electric attribute value, approaches bottom event fault occurring source in fault tree.
It is emphasized that; embodiment of the present invention is illustrative; instead of it is determinate; therefore the present invention includes the embodiment be not limited to described in embodiment; every other execution modes drawn by those skilled in the art's technical scheme according to the present invention, belong to the scope of protection of the invention equally.
