A system and method for monitoring data collection and operation of a power system.

The technical field to which the present invention is applied is related to Supervisory Control and Data Acquisition System (SCADA), Distribution Automation System (DAS), Distribution Control (DCS), Energy Management System (EMS), etc. In the field of power monitoring and control systems.

FIG. 1 is a diagram illustrating a monitoring control management system of a general power system, and includes a monitoring target 1, a measurement system 10, a collection control system 30, a DB management system 50, and a monitoring management system 70. Consists of including.

The monitoring object (1) means a power plant that produces electricity, a power transmission and distribution system that delivers the generated electricity to a consumer, and a load system of a consumer.

This monitoring target 1 will have a variety of forms in a variety of processes. Surveillance control management system is constructed for the management to operate and control such complex and extensive power process efficiently.

The measurement system 10 is based on measurement information such as current, voltage, or modem signal such as a remote terminal unit (RTU) in a power system through a sensor type such as analog, digital, or pulse in power generation and grid processes. Transmission to remote control collection system (30).

The collection control system 30 collecting various field information collects various signals transmitted from the field, converts them into engineering information, converts them into actual values, and calculates new field transmission information by controlling such information.

All such information is sent to the DB management system 50 via the network.

The DB management system 50 manages and manages various data information to suit the purpose. It is mainly composed of real-time operation management unit 51, engineering management unit 53 and history management unit 55, etc., the management program that operates this, and site-specific application programs, basic programs for monitoring and operation are being operated. Here new calculations are calculated and need to be managed.

Information stored and managed here is transmitted to the surveillance management system (70). Although not specifically illustrated, the monitoring management system 70 includes a monitoring management operation unit that manages to monitor or control information, an engineering unit of a DB editing function for a DB management system, and a higher operating unit.

The monitoring management system 70 transmits the control command input by the operator to the monitoring target 1 in the field through the DB management system 50, the collection control system 30, and operates a predetermined measurement controller. .

Here, the specific configuration of the DB management system 50 is as shown in FIG.

The real-time operation management unit 51 of the DB management system 50 is largely composed of two parts, which is a real-time management unit 51-1 for managing analog, digital data, and calculation data of the field, and a real-time management unit 51-. It consists of an application program unit 51-2 that performs various functions by utilizing the information in 1).

The real-time management unit 51-1 is a memory resident database management system, and takes a flat DB form or a relational DB form.

The information edited in the monitoring management system 70 is edited and stored in the engineering management unit 53. This information will be edited as needed by the operator or engineer. The engineering management unit 53 is operated as a commercial relational database management system because real-time performance is not necessary.

This information is engineered and loaded into the real-time operation management unit 51 when necessary, and is operated in real time.

Here, the information for the history is managed in the history management unit 55, connected to the various information of the real-time operation management unit 51 and the information of the history management unit 55 for monitoring and management in the monitoring management system 70, To manage.

The problem of the DB management system 50 is possible only when the configuration of the application program has a relatively simple structure. This is possible when operating as aperiodic or simple monitoring applications (trends, plant markings, alarms, reports, etc.).

When the applied system is highly functional, the supervisory control management system tends to be advanced system, and for this purpose, various application programs need to be operated. For example, advanced control of distributed control system for monitoring control of power plant itself, EMS (Energy Management System) system that monitors and optimally manages the entire power supply status of upper operating system or power system, and intelligent power instead of simple power system monitoring In order to configure and operate a smooth and efficient system such as a supervisory control system, a high-level algorithm suitable for each process operation is introduced.

These advanced application programs should be operated simultaneously with the programs that have basic system functions and application functions in the application program section for safety and efficiency. Maintaining the adopted relational DB method of the conventional method or maintaining the flat method causes various problems as follows.

That is, the problem of the monitoring control management system for a conventional power system is as follows.

This is difficult for various applications to use quickly in the case of searching for, reading, and recording necessary information of each power equipment (transformer, line, generator, etc.) by the application of the power system.

In addition, in the conventional relational DB form, only the downlink exists. That is, in a relational DB, there is a 1: N relationship between tables, which is not easy to search for an entry of the first side table in the N side table. In other words, you need to search the table to find the entry you want. For example, to identify an entry in a table, this is done by using the equipment's ID as the primary and foreign keys. This is useful for location independence and maximum flexibility of entries in the table, but degrades performance and is not suitable for accessibility by various applications.

For this reason, it is not easy to execute various applications, and the operator takes various inconveniences due to the efficiency delay of system performance.

To provide a monitoring data collection and operation system of the power system and its method.

Another object of the present invention is to provide the necessary information through real-time operation management and application-specific management during the initial operation of the monitoring control management system (such as system restart and application program restart) during the operation of the database system of the monitoring control management system of the power system The present invention provides a system and method for collecting and operating monitoring data of a power system that can be stored separately and operated.

Another object of the present invention is to selectively operate any study analysis operation method for real-time mode operation and process modeling and analysis when various advanced applications of the power control system are executed and operated. To provide a monitoring data collection and operation system of the power system and its method.

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

3 is a view illustrating a monitoring control management system of a power system according to the present invention, wherein the monitoring target 1, the measurement system 10, the collection control system 30, the DB management system 100, and the monitoring management system ( 200).

The monitoring target 1, the measurement system 10, and the collection control system 30 of FIG. 3 have the same configuration and function as those of FIG. 1, and only the DB management system 100 and the monitoring management system 200 are shown. Since the configuration is different from 1, the description of the same configuration as in FIG. 1 will be omitted.

First, the real-time operation management unit 110 of the DB management system 100 is largely composed of two parts, which is the DB management unit 120 for operating the database management and the application unit 130 for managing various systems and applications It consists of).

The DB management unit 120 includes a real-time management unit 121 for managing analog, digital data, calculation data of the field, and an application-only management unit 123 having a structure for managing and operating information of an application-specific program. .

The real-time management unit 121 and the application-only management unit 123 is a memory-resident database management system, each of which stores the information of the real-time online and application-specific structure in each DB (122, 124) to build a database.

The application-only management unit 123 is configured to have a table-type data structure in which an index designation method and a parallel separation method of a static database and a dynamic database structure are introduced.

In addition, the file storage management unit 125 is configured to receive the results operated by the real-time management unit 121 and the application-specific management unit 123 periodically or aperiodically to perform management for storage.

In addition, the engineering management unit 150 stores and manages the information edited in the monitoring management system 200 in the engineering DB (152). Since the engineering management unit 150 does not necessarily require real-time performance, the engineering management unit 150 is operated as a commercial relational database management system for operating a hard disk or stored as a CSV (Comma Separated Value) file.

This information is engineered to take the form of offline DB, and when necessary (system initial and application restart) engineered by the real-time management unit 121 and the application-specific management unit 123, if necessary, then loaded in memory resident form It is operated.

In addition, the history management unit 170 stores and manages information for the history, and is connected with various information of the real-time operation management unit 110 and information of the history management unit 170 for monitoring and management in the monitoring management system 200. Display and management.

The surveillance management system 200 performs a MMI (Man Machine Interface) or HMI (Human Machine Interface) function to perform a process for displaying or recording information managed and operated by the DB management system 100.

4 is a table structure of an index designation method built in an application-specific management unit of a DB management system according to the present invention.

The table of FIG. 4 is composed of a first table T1 and a second table T2, assuming that the first table T1 and the second table T2 have a 1: N relationship. Explain together.

First, the application-only management unit 123 is a head processing unit 123-1 and a parent processing unit for storing and managing data of the first and second tables T1 and T2 in the application-only DB 124. 123-2 and a sibling processor 123-3.

In relational DB, only downlink exists. To solve this problem, an index table for equipment identification can be used separately, but it becomes cumbersome to manage.

On the other hand, the main processor 123-2 of the index designation method proposed in the present invention uses an entry index without using a facility ID to have a 1: 1 structure. That is, it is a way to enable uplink, which is used as follows.

First, all related index tables are removed, and the equipment entry index of the related table is replaced with the equipment ID as a foreign key in the table.

For example, instead of inputting a station id as an attribute of the static table of the breaker to be monitored 1, the station entry index of the static data table is used as a foreign key. Therefore, the use of the entry index of the static data table eliminates the need for creating an index table and operating a search process of a desired entry using the index table.

This is useful for the processing of static data and most plant information does not change from time to time. Only variable information requires separate processing, which is easy to perform because it is small. The index designation method of the main processing unit 123-2 is a method for increasing entry searching efficiency of each table by allowing a large amount of data to be efficiently accessed by various application programs and quickly inputting / outputting.

Also, in the conventional relational DB, when searching for the n-side table, which is the second table, using the first table in a 1: n relationship, the location of each entry is designated and used as the foreign key for the entry of the related table. do. Significant time may be required when searching for this.

The proposed method of the present invention solves the problem easily and can satisfy the performance requirements of various applications. In the 1: n relationship, each integer entry is used for both tables. That is, the designation point of the n-th table is designated as an index in the first table.

The management processing unit related to such processing is called the head processing unit 123-1.

Next, in the second table T2, the next entry point of the entry included in the first table T1 is designated as an index. Iteratively repeats in this manner to specify the entry items included in the first table. When repeated in this manner, the last entry item included in the first table is assigned a zero value. Management of this type of processing method is referred to as auxiliary processing unit 123-3. In this way, it is possible to easily determine all of the entry groups included in the n-side table, which can be easily read by an application program.

The technology proposed in the present invention is a data that is required for the effective management and management of a large amount of information data in real time in the application of various field applications when operating a database that centrally manages the field data and related information of such a system. The invention is invented to effectively improve the performance of the data management function of the comprehensive monitoring and control system by effectively configuring the information processing table.

5 is a table structure of a parallel designation scheme built in an application-specific management unit of the DB management system according to the present invention.

This configuration diagram includes a static management unit 123-5 for managing the static table ST1, and a dynamic management unit 123-6 for managing the n dynamic tables DT1 to DTn. The application program unit 130 Static and dynamic data are stored and managed by each application.

The existing DB processing method uses both static and dynamic information of the entry data in a table to form a single table. This is difficult for various applications to use quickly in the case of searching for, reading, and recording necessary information of each facility (transformer, line, generator, etc.) by the application program of the power system.

In order to solve this problem, the present invention uses a parallel table method. Each of the facilities (transformer, breaker, bus, etc.) each has a static information and dynamic input / output information having a variety of characteristics, the parallel structure designation method according to the present invention is a static management unit (123-5) for each facility The static table side manages information such as static data (equipment name, equipment characteristic value, etc.).

By managing these static tables separately, the surveillance management system 200 is changed in a long period of time to maintain a fixed state.

Next, the dynamic management unit 123-6 manages dynamic information of each facility. Each of the first to n-th dynamic tables has a table entry structure in parallel with the same positions as the entries of the static table. In other words, each facility has the same entry row number.

Each dynamic table is used to be separated by application. That is, various application processing programs are operated in the application program unit 130. The first application-only processing unit 133-1 processes data of the static table ST1 side and the first dynamic table DT1 side for application processing. After receiving the input data and performing its own dedicated processing, the processed information is recorded in the first dynamic table DT1 which is a dedicated table.

Next, the second application-only processing unit 133-2 receives the contents of the static table ST1 and the first dynamic table DT1, which is the result of the previous processing, as input and performs processing, and then the second dynamic table as a dedicated table. Write to (DT2).

Repeated in this manner or performed by the n-th application-only processing unit 133-n according to the operator's request method as necessary. Therefore, each application program can easily search for and use the static table entry order. This method is called parallel partition table method, and various application programs access table information exclusively to reliably acquire and record table information, and make program operation monitoring and management more efficient.

6 is a flowchart illustrating an operation flow related to real-time and study mode operation of the monitoring control management system according to the present invention.

In the existing relational DB structure, data processing is slow, so it is not possible to perform various real-time and study analysis by executing an application program. Traditional relational DBs only allowed the general process of analyzing and displaying alarms, trends, or graphs.

However, in the present invention, as data is constructed in an index designation method and a parallel structure designation method, data processing speed is increased, so that an application program can be executed to operate in real time and study mode.

In FIG. 6, an operation method of an application program using the real time managing unit 121 and the application dedicated managing unit 123 is proposed.

In the database editing process (S11), the contents of various databases for the application process operation are edited. Here, input and output parameters and items (limit, scan period, etc.) of various analog, digital, pulse, operation points, and equipment are defined.

This information can be taken offline to take the form of a relational database in the form of a file or to perform arbitrary schema definition in the form of a CSV file, which is stored in the engineering management unit 150 of the DB management system 100.

In the real-time online operating DB and application-only DB generation process (S12), the information stored in the engineering management unit 150 is loaded into the real-time management unit 121 and the application-only management unit 123 described above.

The operation of the application programs is as follows.

First, the application program group related to the real-time cycle and the type of the non-periodic application program are divided and operated in a separate manner. After the type of the application is determined (S13), it is separated and operated in each operation manner.

The operation of the application group in the real time cycle is as follows. First, in the field data collection process (S14) to collect the information measured by the site that is the monitoring target (1) from the sensor and stores in the real-time operating DB 122 of the real-time management unit 121.

In collecting real-time and application-specific DB information (S15), the application program specified by the corresponding cycle and order reads information required by the real-time management unit 121 and the application-only management unit 123 through each dedicated API (Application Program Interface). . The application-only management unit 123 stores the read data in the application-specific DB 124 in the index designation method and the parallel structure method as shown in FIGS. 4 and 5 to build a database.

Next, the application program specified by the cycle and the sequence is executed to show the required calculation result value (S16).

In the calculation result information DB recording process (S17), the calculation result value is recorded in the DB 124 of the application-only management unit 123.

This information is transmitted to the monitoring management system 200 through the data information display and storage process (S18) to be displayed on the screen of the MMI management unit 250 or stored in the hard disk.

Herein, it is repeatedly performed through the first predetermined designated cycle process S19 until the last order application program of the ordered periodic application program is terminated. The non-sequential cycle application program is performed through an iterative process when there is an operator request and an event response request through an operator request and an event response process process (S20).

Meanwhile, in the case of a program that periodically collects site data, the program is repeatedly processed through a process S21 for a designated second cycle. The process for a given cycle is repeated through this process, even if it is the first startup of a sequential cycle application.

In addition, in the case of the study application program classified in the type classification process (S13) of the application program, the operation is arbitrarily calculated by the operator. If there is a request in the operator request and event response classification process (S23), it continues.

In the real-time and application-specific DB information copying process (S24) to copy the database stored in each DB (122, 124) of the real-time management unit 121 and the application-only management unit 123. The application reads the copied real-time operational database and application-specific database. This process is performed in the process of collecting real-time and application-specific DB information (S25).

In the application program execution process (S26), the calculation result is output by performing a function of the corresponding application program. In the calculation result information DB recording process (S27), the calculation result information is recorded in the application-specific DB 124 of the application-dedicated management unit 123 and stored in the hard disk as necessary. In the case of an ordered application program, the iteration process is performed again.

FIG. 7 is a diagram illustrating a configuration of an operation management unit for real time mode operation in FIG. 6.

Surveillance management system 200 includes a real-time operation management unit 210, and the MMI management unit 250 to display and operate the information for input.

Surveillance management system 200 through the real-time operation management unit 210, the application program and related programs of the monitoring control management system is the ordered application unit 135 and the non-order application program unit 137 of the DB management system 100. Comprehensive program operation management for the case of operation by

That is, the sequential application program unit 135 represents a case in which each of the applications (App. 1 to App. N) must perform operations in order. Each application program collects the necessary information from the real-time operation DB 122 through the real-time management unit 121, or collects the necessary information from the application-only DB 124 through the application-only management unit 123 or the data processing for its own purpose. By performing various operations, the result is recorded in the DB 122 through the real-time management unit 121, or the necessary information is recorded in the DB 124 through the application-only management unit 123.

During this process, each application program of the sequential application program unit 135 is necessarily operated in sequence, and these operation sequences are managed at the request of the operator, and are sequentially operated by the real-time operation management unit 210 during operation. Running applications may hang.

In addition, the real-time operation management unit 210 may manage the operation order of the non-order application program unit 137. The programs App.1 to App.n of the out-of-order application program unit 137 are operated when their own operating cycles are not specified in order. Each application program accesses and acquires information similar to the program of the application program unit 135 to access each DB 122, 124 through the real-time management unit 121 and the application-specific management unit 123. And record.

8 is a diagram illustrating a configuration of an operation management unit for the study operation mode in FIG. 6.

The monitoring management system 200 includes a study analysis operation management unit 220 and an MMI management unit 250 to display and operate information for display and input managed by the study analysis operation management unit 220.

The study analysis operation management unit 220 of the monitoring management system 200 reactivates the operation of the operation required by the operator when necessary by utilizing the application programs.

To this end, the study operation management unit 127 of the DB management system 100 manages the operation of operating various application programs (App.1, App.2) of the study-related application program unit 139. In addition, in the study operation management unit 127, the study DB 128 having the same copy structure for the study analysis of the database stored in the DB 122 of the real-time management unit 121 and the DB 124 of the application-specific management unit 123 You will manage the creation.

It can either use one part of the application or perform independent management to run it directly. In addition, the study operation management unit 127 is responsible for the operation management of the study DB for the study analysis.

In this case, the real-time mode operation provides a method of dividing the structure of an ordered periodic application and an ordered periodic application. In addition, when real-time mode operation and study analysis operation method are applied, the management program for this provides a method of managing the operation operation.

As such, to manage the database management of the real-time operation DB management part and application-related programs that are in charge of real-time management of the structure of the database management system, which is a management system for the monitoring control management system, for effective DB operation of the power control system.
