FIG. 1 is a process flow diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of examples of the present invention, and not all examples. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
The method for automatically auditing monitoring signals of a master station of a power system in this embodiment, as shown in fig. 1, includes the following steps:
step (1), signal comparison
And establishing a signal library for automatic verification, comparing the generated main station signal with the standard signal by taking the standard signal as a unique basis for verification, normalizing the keyword level, and comparing the signals by taking the standard signal as the basis.
According to standard documents such as substation equipment monitoring information technical specifications issued by the south network company, different standard signal libraries are formed for substations with different attributes such as substation types, voltage levels and wiring modes. And meanwhile, establishing the relation between the interval type and the equipment signal, and appointing the standard of the maintenance standard signal. And establishing a keyword maintenance rule of the standard signal, and establishing a signal library for automatic examination according to the signal matching rule incidence relation. And adopting a natural language analysis technology to perform data structured analysis on the monitoring information to be audited, splitting the signal into a plurality of keywords, and establishing a model of the matching relation between the keywords and the standard signal. Generating different standard signals according to different transformer substations, voltage levels, interval types and equipment types, automatically calculating the similarity and matching degree of the signal to be audited and the standard signals according to the established model of the matching relation, and judging whether the signal to be audited can be automatically matched into a standard signal library according to the result. And aiming at the change of different standard libraries, version management is provided, the difference of signal change is stored by self, and the change process of the standard signals is convenient to maintain.
Step (2) establishing association
And performing data analysis on the master station signals generated by the system, and establishing an association relation between the master station signals and the standard signals by utilizing a comprehensive algorithm according to different equipment feature points represented by the master station signals except the placeholder in the master station signals generated by the system.
Signals are classified to equipment manually in an early stage, and the rules of the signals are found out. Or, the naming rule of the signal name in the monitoring information table is analyzed by combining the monitoring information table specification and the field condition issued by the south network, and then the substation information table is directly analyzed, so that the division effect of the preliminary stage is not ideal, and the inapplicable rule in the preliminary stage needs to be continuously adjusted.
Step (3) calculating the matching rate
And establishing a keyword automatic matching model, calculating the matching rate of each main station monitoring signal and the related standard signal, and prescribing the passing rate of the auditing and changing the auditing passing standard according to the matching rate.
After the supervisory signals are classified into devices, experience of keywords related to standard signals is accumulated, and priority levels of the assigned keywords are appropriately set in conjunction with field conditions. For example, 3 key fields are set for a certain standard signal, and when the monitoring signal is compared with the standard signal by taking equipment as a unit, all the fields are satisfied and are 100%; and if the signal meets 1, calculating according to the priority ratio, and judging the standard degree of the secondary signal according to the degree of the key part of the signal.
The standard rate of the total station standard signal matching is an evaluation value for counting the standard rates of all the monitoring signals matched to the equipment, and the monitoring signals are compared with the keywords in the standard signal library one by taking the equipment as a unit, and finally the standard rate of the total station monitoring signals is calculated. The improvement suggestions can be modified according to field requirements, the standard degree of the monitoring signals of the current transformer substation is mainly highlighted, the monitoring signals are subjected to reasonable and standard naming requirements during subsequent transformation of the transformer substation, and a standard signal library is further perfected.
And maintaining a standard signal library, wherein the initial version is obtained according to the technical specification of the monitoring information of the substation equipment uniformly released by the south network. Aiming at the actual construction condition of the provincial and local transformer substation, the supplementation and the improvement can be properly carried out according to the actual situation. The first automatic signal matching may have some factors of inaccurate classification, and the generated improvement opinions are combined to search for the reason of low signal standard rate, adjust corresponding keywords and priority, and corresponding analysis algorithm, so as to adapt to the law of on-site monitoring signals.
The system is designed based on IEC61850 standard specifications and interfaces, a monitoring information table provided by a master station automation system and an equipment account provided by a PMS are dispatched through E8000, a standard signal library is maintained, a monitoring information table analysis model is designed, agreed rules of signal keywords are automatically matched, standard rate and improvement opinions of a transformer substation are generated, and the system automatically identifies special keywords in signals, such as voltage levels, interval numbers, switch numbers, equipment models and the like, by utilizing a natural language analysis technology. And splitting the monitoring information into a plurality of keywords.
Specific examples are as follows:
"110 kV general city I return wire 167 circuit breaker spring does not store energy", split it into: 110kV + first return wire of Pucheng +167 circuit breakers + spring non-energy storage, the system automatically replaces the signal as "{ voltage grade } { interval number } { switch number } spring non-energy storage", and meanwhile, according to the keyword eye of "spring non-energy storage", the system judges that the signal is the type of the circuit breaker spring mechanism. Therefore, monitoring personnel can be helped to accurately judge the equipment state or fault reason represented by the monitoring signal, the normal work of the main station of the power system is ensured, and the method can be widely applied to the technical field of information of the power system.
It should be emphasized that the embodiments described herein are illustrative rather than restrictive, and thus the present invention is not limited to the embodiments described in the detailed description, but also includes other embodiments that can be derived from the technical solutions of the present invention by those skilled in the art.
