Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The design idea of the invention is as follows: effective information in the transformer substation monitoring information table is extracted as an important basis for automatic disposal, and a common interval library and a public equipment monitoring library for automatic disposal are established by means of the structural association relation of the monitoring information table. According to different transformer substations, voltage levels, interval types and equipment types, effective information is automatically extracted and automatically filled into the CIME file according to the data structure requirements of the CIME file. And adopting a manual intervention mode for the information which cannot be acquired through the monitoring information table. In the processing process, the full information acquisition of the CIME file is realized through the secondary processing of the computer on the existing information and a small amount of manual intervention; the CIME file template is generated by analyzing the existing CIME file, and finally the function of generating the CIME file through the transformer substation monitoring information table is realized by integrating the acquired information and the CIME template.

Based on the design concept, the invention provides a method for automatically generating a CIME file based on a transformer substation monitoring information table, as shown in FIG. 1, comprising the following steps:

step 1, formulating a CIME data structure.

In order to automatically generate a CIME file, the following CIME data structure is prepared, and the following table structure and field structure of the CIME file are described:

table 1: CIME File Table Structure Specification

Table 2: CIME file field generation description

Note: the fields of each table are more, the fields which are not listed are mainly divided into two conditions, one condition is that the filling content of the fields which are not listed is repeated, and the description is not repeated; according to actual requirements, part of the two groups are defaulted to be NULL.

And 2, reading the monitoring information table of the transformer substation to obtain remote signaling, remote measuring and remote control data.

In the step, the checked and accepted fixed value list in the monitoring information table is obtained through the substation monitoring information table, and the fixed value list comprises data such as remote signaling, remote measuring and remote control data in the substation monitoring information table.

And 3, checking the accuracy of the transformer substation monitoring information table.

In the step, the acquired monitoring information table is subjected to basic checking work, so that the reliability and the accuracy of a data source are ensured, and the requirement of subsequent data extraction is met. The basic checking work in this step includes the following:

(1) checking the topological relation of primary equipment;

(2) whether the signal description is repeated;

(3) whether the remote signaling signal contains the condition of no-alarm classification or not;

(4) whether the signal length meets the requirement;

(5) whether a signal without a dot number is contained;

(6) whether the voltage grade and interval information of the three remote data are consistent or not;

(7) and judging non-null data.

And 4, establishing a monitoring information structured model relation.

The obtained monitoring information table data needs to be processed for the second time as the basis of the effective information of the CIME file, the existing monitoring information table is analyzed and summarized, the structural processing of the monitoring information table is realized, and the preparation is made for the subsequent information filling.

The specific implementation method of the step is as follows:

and 4.1, establishing a typical association relationship of the transformer substation, the voltage grade, the interval, the equipment and the signal.

And 4.2, constructing a model of a typical wiring form, and realizing management of the typical wiring form under all voltage levels, wherein the typical wiring form under 220kV in the embodiment comprises double-bus double-division, double-bus single-division, double-bus and the like.

And 4.3, constructing a model of a typical interval, and managing a typical interval list under each voltage class and a wiring form, wherein the typical interval under the 220kV double-bus double-division wiring form in the embodiment comprises a line interval, a bus-coupled interval, a sectional interval, a bus interval and the like.

And 4.4, constructing a model of the interval typical equipment, and managing a typical equipment list under each type of interval, wherein the 220kV line interval comprises a circuit breaker, a disconnecting link, a control loop, a line protection device, a measurement and control device, a line PT (potential transformer), an intelligent terminal, a merging unit and the like.

And 4.5, carrying out special treatment on the structuralization of the public equipment: because the difference of the types, the quantities and the like of the equipment related to the public equipment of each transformer substation is large, a set of data model containing the whole quantity of public equipment is constructed, and an input supplement strategy is provided to ensure the integrity of the data.

And 4.6, integrating the common interval and the public equipment.

And establishing a complete monitoring information structured model relationship through the steps.

And 5, splitting, analyzing, processing and storing the data into the CIME file template according to the description generated by the CIME file field.

The specific implementation method of the step is as follows:

and 5.1, specially processing information such as station names, intervals, equipment, signal description and the like according to the format (tables 1 and 2) of the CIME file. The factory station name is processed into a format of area and transformer station name; all intervals need to be guaranteed to contain voltage levels and interval names; the equipment only contains equipment information, such as a circuit breaker, a disconnecting link, a grounding disconnecting link, a bus, a line, a main transformer, a capacitance reactor and the like; the signal description generates a five-segment signal according to the specification.

And 5.2, extracting the processed data according to the requirements of the CIME file, directly converting the data into the data of the CIME file while extracting, writing the data according to the requirements of the CIME format, and automatically generating the content of the CIME file at the moment.

and 6, supplementing the information which cannot be acquired through the monitoring information table through manual intervention data.

Since some information cannot be obtained from the monitoring information table, human intervention is required. The content of human intervention mainly comprises: filling in an area id; maintenance circuit breaker types (ordinary switches, trolley switches, bus coupler/section/bypass switches, transformer branch switches, etc.), capacitive reactance types (parallel capacitors, series capacitors, parallel reactances, series reactances, etc.). Other data are automatically generated by monitoring the original data of the information table.

The specific implementation method of the step is as follows: obtaining reference voltmeter information, obtaining area meter information of the area, setting selectable items of a human intervention part, and selecting from the selectable items without personal filling authority. And manually filling and selecting the types of the circuit breakers and the capacitive reactance devices. The interval type field of the breaker table as in step 4 requires human intervention to select the "normal switch" type.

And 7, integrating the two parts of information generated in the steps 5 and 6 to realize the generation of the CIME file.

The step integrates two parts of information of automatic generation information and manual intervention information, completes the supplement of full information and realizes the generation of CIME files. The specific method comprises the following steps:

in this step, all information required by the CIME file is integrated by the data source and data generation method in table 2, and an initial version x substation CIME file is generated.

The example in the step 4 shows that most of information can be automatically generated through the monitoring information table, the human intervention ratio is less, and the requirements of convenient and fast generation of CIME are met.

And 8, checking and identifying the CIME file.

And checking the integrity and correctness of the data of the CIME file of the X x transformer substation of the initial version. And after the checked information is processed by a computer or manually modified (for the computer, the checked information can be directly modified, such as requirements of Roman characters and the like, and for the problem items which can be identified but cannot be modified by the computer, the problem items are checked by the computer, and then the problem items are manually modified and rechecked), the checked information can be repeatedly checked, and then the checked information can be introduced into the D5000 intelligent scheduling technology support system of the power grid I area.

Through the steps, the function of automatically generating the CIME file based on the transformer substation monitoring information table can be realized.
