Description

Technical Field [0001] The present invention relates to a domain data input operating system for constructing a CIM-based SCADA system, and a domain data input method using the same. [0002]

The present invention relates to a domain data input operating system for constructing a CIM-based SCADA system and a domain data input method using the same. More particularly, the present invention relates to a domain data input operating system for constructing a CIM-based SCADA system by inputting RTU data and parsing the RTU data according to a structure of a CIM RDF Schema And a domain parser (D-Parser) for automatically generating a CIM XML file, thereby reducing the input cost and inputting time of the power system data. A domain data input operating system, and a domain data input method using the same.

Common Information Model (CIM) is a standard model that enables system integration and information exchange based on common information model. It is collectively referred to as IEC 61970, IEC 61968, IEC 62541, and is based on IEC 61970 And provides a general information model and message / file schema for exchanging messages / files between EMS (Energy Management System) systems.

For example, according to CIM, given the CIM RDF schema described in IEC 61970-501, the EMS power system model can be exported as an XML document, in which all the tags used in the CIM XML are provided in the CIM RDF schema .

The results of the CIM XML model exchange document can be parsed and the information entered into the external system allows the implementer to generate CIM XML documents in a variety of ways similar to using a programming language.

However, although the CIM standard describes the CIM XML document generation for interoperability, it does not provide a standard for constructing the SCADA (Supervisory Control And Data Acquisition) system based on the CIM of SCADA.

Therefore, according to the related art, it is troublesome to construct power system data through a separate DB editor in order to construct a CIM-based SCADA system, There is a problem that it takes considerable time.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 illustrates a domain data input operating system for constructing a CIM-based SCADA system according to the present invention.

1, a domain data input operating system 100 for constructing a CIM-based SCADA system according to the present invention includes a user terminal unit 110, a DB editing server unit 120, and a DB server unit 130 .

The user terminal unit 110 instructs the DB editing server unit 120 to generate a CIM XML file by an operator performing a CIM-based SCADA system construction work.

The DB editing server unit 120 includes a domain parser 121 and a power system data storage unit 122. The DB editing server unit 120 generates power system data in accordance with a CIM XML file creation command of the user terminal unit 110 in the form of CIM XML To generate a CIM XML file, which will be described later in detail with reference to FIG.

The DB server unit 130 implements proprietary power system data by importing the CIM XML file generated from the DB editing server unit 120.

FIG. 2 illustrates a method of generating a CIM XML file by a domain parser (D-parser) according to the present invention.

Referring to FIG. 2, a domain parser (D-parser) 121 receives RTU data (10).

Here, the RTU data 10 is a data transmitted by a RTU (Remote Terminal Unit) having data obtained by a substation, a transformer, a relay, etc., and has a CSV (Comma Separated Values) file structure such as scc_analog_id, scc_code, scc_point_type, scc_point_number, scc_point_name, scc_station_number, scc_init_value, scc_alarm_class, scc_low_limit, scc_high_limit, scc_low_reason, scc_high_reason, scc_scale_factor, scc_offset, scc_ai_index, scc_scan_block, scc_unit_name, input_date, ads_use_flag and tcp_use_flag.

In other words, the RTU data refers to data obtained from the feeder branch, which can be classified into data having analog point information and data having status (digital) point information.

Here, the data having the analog point information will be briefly described. The feed point analog id (1 to xxxxx), the feedfork code (1 to xxx), the feedpoint point type (1 or 3), the feedpoint point id (1 to xx), Low_limit (xxx), High_limit (xxx), Low_reason (xxx), High_reason (xxx) scale factor (xxxxxxxx), offset (mostly 0), RTU ai index (1 to xxx), scan block (scan time: 10 seconds), unit name (kV or A or MW or MVAR or HZ or PF) Modify) date, ads use flag (2 or 0), and tcp use flag (2 or 0).

On the other hand, as data having the status (digital) point information such as, scc_status_id, scc_code, scc_point_type, scc_point_number, scc_point_name, scc_station_number, scc_group_name, scc_init_value, scc_normal_state, scc_state_calculator, scc_alarm_class_1, scc_alarm_class_2, scc_di_index, scc_do_index, scc_scan_block, input_date, ads_use_flag, tcp_use_flag etc. .

Here, the use of data having status (digital) point information will be briefly described. The feed point status id (1 to xxxxx), feed point code (1 to xxx), feed point type (1 or 3) (1 or xxxxx), station name (1 to xxx), group name (open / closed or stop / motion or ...), initial value (-1), steady state value ), The calculated value (1), the alarm class 1 (1 to xx), the alarm class 2 (1 to xx), the di index (watch point 1 to xxx), the do index (control point 1 to xxx) time: 300 seconds), input (modification) date, ads use flag (2 or 0), and tcp use flag (tcp / ip communication status: 2 or 0).

Therefore, by discriminating the values contained in the respective columns of the RTU data, it is possible to check whether the RTU data is normal or abnormal.

Next, the domain parser (D-Parser) 121 parses the CIM RDF Schema 20.

Here, the CIM RDF Schema 20 collects the CIM (Common Information Mode, 21) and RDF (Resource Definition Framework) syntax 22 prepared in the UML (Unified Modeling Language) form and analyzes the schema schema).

Next, the domain parser (D-parser) 121 parses the RTU data (10) according to the structure of the CIM RDF Schema (20).

In other words, a task of extracting and converting power system resource data through a domain parser (D-parser) 121 is first performed.

Here, the power system resource data refers to facilities (such as transmission lines, buses, transformers, breakers, disconnectors, earth breakers, relays, etc.) constituting a substation.

The domain parser (D-parser) 121 extracts the power system resources required for the control system, that is, the facility name of the substation, by analyzing the syntax of the analog point name and status point name of the RTU data described above. After separation, duplicate data is deleted.

In addition, a task of extracting and converting measurement data is performed through a domain parser (D-parser) 121.

Here, the measurement data refers to the analog data and the status data that the actual SCADA system exchanges information in real time. When the operation is processed, measurement data to be connected to the power system resource extracted in the above, i.e., equipment data is extracted.

The power system data storage unit 122 stores the CIM XML files generated by the domain parser 121.

FIG. 3 is a flowchart illustrating a process of inputting domain data for constructing a CIM-based SCADA system according to the present invention.

Referring to FIG. 3, a domain parser (D-parser) 121 has a first step (SlO) for receiving RTU data.

Next, a second process (S20) is performed to determine whether the structure of the received RTU data is normal.

If it is determined in step S20 that the structure of the RTU data is not normal (NO), the process is terminated. If the structure of the RTU data is determined to be normal in the second process S20 (Yes) And a third step S30 for extracting and converting power system resource data.

Next, a fourth step (S40) of extracting and converting the measurement data is performed.

Next, there is a fifth step (S50) of checking whether the extracted power system resource data and extracted measurement data are overlapped.

Next, a sixth step (S60) of verifying the power system resource data and measurement data with reference to the CIM RDF schema is provided.

In this case, the sixth step S60 may be performed while extracting the data in the course of the third step S30 and the fourth step S40. In this case, however, the verification work time increases due to the double verification operation Therefore, if the verification operation is performed at a time after the file creation is completed, the operation time can be shortened and the operation is performed after the fifth step (S50).

As a final step, there is a seventh step (S60) of generating a CIM XML file.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention.
