Abstract

The invention provides a power equipment monitoring information point table automatic generation method. With the aid of standard data source end maintenance rules, monitoring signal naming rules, and agreed signal type, quantity and acquisition rules for different equipment models and different wiring modes, expert library experience is introduced and information is extracted to establish monitoring access expert decision libraries for different manufacturers, different equipment models and different wring modes. A substation 'three-remotes' information table and a monitoring information table having forms with monitoring information integration attributes are generated automatically with the equipment ID as a radiation source according to the storage and association of power equipment monitoring information points and with the aid of an expert decision library. The method can be widely used in power companies and transformer substations.

Description

A kind of electric apparatus monitoring information point table automatic generation method

Technical field

This method is invention on expert knowledge library based on data drive type, refers in particular to deposit power system transformer substation electric apparatus monitoring information and has access to the professional domain knowledge required for managing with account for information.

Background technology

The present invention provides a kind of electric apparatus monitoring information point table automatic generation method, by authority data source maintenance regulation, monitor signal naming rule and to treaty rules such as distinct device type, the signal kinds of the mode of connection, quantity, collections, introduce experts database experience, Extracting Information, different manufacturers, distinct device type, the different mode of connection are set up respective monitoring and accessed expert decision-making storehouse, automatically generates transformer station's ' three is distant ' information table and final monitoring information table.

Summary of the invention

The present invention provides a kind of electric apparatus monitoring information point table automatic generation method, it is achieved the storage of electric apparatus monitoring information point and association, by expert decision-making storehouse, it is achieved with device id as radiation source, forms the form with the integrated attribute of monitoring information.

Its realize the method to implement step as described below.

1. set up monitoring signal maintenance relational norm

According to the different signal types hierarchical relationship when maintenance signal rule, automatically forming signal typing in signals collecting database and relation sets up restricted model, concrete signal type, hierarchical relationship and level attended operation specification are shown in Table 1.

2. set up the tables of data with device id as major key, divide four dimensions safeguard according to interval properties, device type, electric pressure, the mode of connection

Divide as follows by interval properties: main transformer body, main transformer high-pressure side, main transformer medium voltage side, main transformer low-pressure side, line segregation, mother interval, section gap, bus interval, capacitor standoff, reactor interval, changing distance used, arc suppression coil, small current neutral grounding, electricity consumption of standing, direct current, public interval.

By device type divide as follows: converting equipment, relay protection, automation, direct current, fire-fighting, other.

Divide as follows by electric pressure: 500kV, 220kV, 110kV, 66kV, 35kV, 10kV.

Divide as follows by the mode of connection: double mothers couple segmentation, double female single segmentation, double mother, single mother partition, 3/2 wiring, single mother.

3. set up forward reasoning mechanism experts database model

Sum up monitoring information extraction and analysis rule according to equipment and network structure feature, obtain monitoring dynamic parameter；With monitoring device ID as Rule of judgment, obtain facility information and safeguard the intrinsic static parameter of this equipment in database；Structure monitoring information knowledge storehouse, and associate above monitoring device Dynamic attribute values and static attribute value, draw this equipment real-time status attribute at present.More than implement flow chart as shown in Figure 1.

Monitoring information knowledge storehouse mainly carries out setting up with the form of tables of data, is broadly divided into system alarm list, system event list, device type table, protects information configuration table.

(1) system alarm list

The database of system alarm list divides according to equipment, and different equipment exists corresponding alert list, and these lists record the warning information that these distinct devices are likely to occur respectively.

(2) system event list

System event list is exactly mainly the set that in storage system, all contingent equipment fault events or equipment irregular operating event are formed.

The tables of data attribute major design of system event comprises: event title, process instruct, block mark, corresponding device type, affiliated plant stand and alert list.

Illustrate:

Processing guidance is to indicate after this event occurs, and is used for the text policy paper title providing accident to instruct to operations staff；Block mark refers to that blocking mark indicates whether this event is in blocked styate, and 1 represents that block, 0 expression are not blocked, when event is in blocked styate, then no matter whether this event occurs, and knowledge base all will not report this event；Alert list refers to after this event occurs, the system alarm set to this event that monitoring system is reported.

(3) device type table

Being mainly used in storing all devices type of transformer station, all these different equipment list unifications are described by device type table.Structure is as shown in Figure 2.

(4) protection information configuration table

Mainly act on warning information pretreatment, be a configuration mapping table of the warning message turning to knowledge base to be capable of identify that warning information.

4. combine primary equipment wiring diagram, generate the form with monitoring information topology attribute

Artwork data are read in expert decision-making storehouse, are associated by unified monitoring device ID mark, it is achieved graphic and model integration analysis, obtain the monitoring information point table with primary equipment wiring diagram topological attribute.

Fig. 4 monitors information specialist's solution bank and generates monitoring electrical equipment control point enforcement table flow chart.

Concrete analysis is implemented

1. set up electric apparatus monitoring information norm associated data table

The Flag mark of each condition in mark monitoring signal instructions table, the language of corresponding condition is described and is stored in other tables of data, designs and refer to Fig. 3 by each Flag institute.

2. to automatically generate the enforcement step of monitoring point table as follows for monitoring information specialist's solution bank:

(1) data sampling is started, according to communication protocol, data are stored in real-time data base with order set in advance, refresh the content of real-time data base, and through data prediction, multiple configuration needed for synthesis decision-making, it is put in temporal data table, and runs the operation constantly monitoring high-tension apparatus always；

(2) enable Analysis of Policy Making, and as data sampling, one is activated the operation then running constantly monitoring power equipment continuously；

(3) Analysis of Policy Making first by data pretreated in temporal data table through the condition matching judgment of knowledge base, the state such as decision systems fortune；

(4) combine primary connection figure topological relation to analyze and the static attribute information of monitored device, automatically generate power equipment information point form.

Above idiographic flow is implemented to refer to Fig. 4.
