Description

Simulation device and method for automatic linking of PMU {SIMULATION APPARATUS FOR AUTO LINKING PMU AND METHOD THEREOF}

The present invention relates to a simulation device and method for automatic connection of PMU. More specifically, it analyzes RTDS (Real Time Digital Simulator) draft data and transmission line configuration relationship data, and allows the user to install a PMU (Phasor Measurement Unit). This relates to a simulation device and method for automatic connection of PMU that allows you to automatically analyze the number of PMUs required for each rack and which rack the busbar is in when you input the desired busbar information.

In general, a Phasor Measurement Unit (PMU) is a device that acquires data at a maximum of 240 sampling cycles per second for voltage, current, phase, and frequency acquired from the power grid, and is time-synchronized with GPS. When an accident occurs in the power grid, the dynamic characteristics of the power grid can be monitored and analyzed at the same time. In particular, as inverter-based facilities with very fast control speeds such as power grid special facilities (e.g. HVDC, FACTS) and new and renewable energy (e.g. solar power, wind power) are increasing, PMU data is required for stable operation of the power grid. Precise monitoring and operation characteristic analysis are required, and if necessary, facility control is possible with auxiliary control signals. Currently, a total of 51 PMUs are installed and operated in substations above 345kV in Korea.

At this time, the PMU is installed in an energy center (e.g., substation), acquires data, and transmits the data to the upper server through a high-speed communication network.

However, since the purpose of the PMU installed in the field is mainly to monitor the power grid, accident analysis, accident reproduction, and control characteristic analysis are limited.

Therefore, by utilizing a realistic real-time simulator (Real Time Digital Simulator, hereinafter RTDS) to generate virtual PMU data, it is possible to overcome the limitations of data acquired in the field and perform various analyses. PMU data can be used to develop or verify various power grid monitoring algorithms.

However, in order to operate the RTDS, draft data for the entire system must first be created.

For example, the domestic full-system draft is created using the PSS/E (Power System Simulator for Engineering) conversion program provided by RTDS, and uses about 30 racks. At this time, each time the draft data is newly created, the location of the busbar for each rack and the transmission line configuration are changed, so the previously configured PMU information cannot be reused.

Meanwhile, in the draft configuration screen of RTDS, a virtual PMU can be installed using the current of the transmission line, the voltage of the bus bar, and an RTDS communication card (e.g. GTNET card), and data can be generated according to the C37.118 international standard. .

For reference, when configuring a PMU for the purpose of monitoring all 345kV substations in Korea, approximately 500 PMUs must be configured.

However, it is realistically impossible to configure about 500 PMUs by hand.

The reason is that, firstly, all elements that monitor current must be activated in the model representing the transmission line in RTDS (e.g. T-line model), and secondly, each measured A, B, and C phase current must be independently monitored. You must specify a name. For reference, all default values are initially entered as the same value. Thirdly, it is not easy to find the target location for the PMU to be installed in about 30 racks.

Meanwhile, PMU data generated in RTDS can be acquired, organized, and analyzed through linkage with PDC (Phasor Data Concentrator).

However, in order to connect the PMU data to the PDC, the PMU configuration information (e.g. IP, port, etc.) must be entered. This requires that the configuration information for the PMU created from the draft data of the RTDS be accurately entered into the PDC settings. However, if the draft of the RTDS is changed, the PDC configuration must also be changed, so there is a problem in that the existing configuration cannot be reused.

Accordingly, in this embodiment, RTDS draft data (e.g., *.dft) and transmission line configuration relationship data (e.g., *.dtp) are analyzed, and when the user inputs the busbar information on which to install the PMU, It automatically analyzes the number of required PMUs and which rack the busbar is located in, automatically activates current channel monitoring elements for monitoring current channels in the transmission line, and inputs current channel names independently. In addition, each PMU H/W is assigned to the PMU module. There is a need for technology to automatically configure W information (e.g. IP information, port information, voltage, current name assignment, etc.) and automatically link the information of PMU H/W configured in RTDS to PDC.

In addition, the present invention automatically analyzes the number of PMUs required for each rack and which rack the busbar is in, automatically activates the current channel monitoring element for monitoring the current channel of the transmission line, and independently inputs the current channel name, Each PMU H/W information (e.g. IP information, port information, voltage, current name assignment, etc.) is automatically configured in the PMU module, and the H/W information of the PMU module configured in RTDS is sent to the PDC (Phasor Data Concentrator). The purpose is to provide a simulation device and method for automatic connection of PMU that allows automatic connection.

Hereinafter, an embodiment of a simulation device and method for automatic connection of PMU according to the present invention will be described with reference to the attached drawings.

In this process, the thickness of lines or sizes of components shown in the drawing may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, definitions of these terms should be made based on the content throughout this specification.

Figure 1 is an exemplary diagram showing the schematic configuration of a simulation device for automatic connection of PMU according to an embodiment of the present invention.

As shown in FIG. 1, the simulation device for automatic linkage of PMU modules according to this embodiment includes a data input unit 100, a control unit 300, and a data output unit 400. The control unit 300 includes an RTDS busbar and transmission line connection relationship determination unit 310, an RTDS required number of PMU per rack determination unit 320, a PMU module creation unit 330, and a PMU H/W information connection unit 340. Includes. However, the detailed components 310 to 340 of the control unit 300 are intended to help understand the operation according to this embodiment, and in fact, the control unit 300 can perform the functions of all detailed components 310 to 340 in an integrated manner. Please note that this may be possible.

The data input unit 100 includes the bus bar number on which the PMU is to be installed, RTDS draft data (e.g., *.dft), transmission line configuration data (e.g., *.dtp), and PDC (Phasor Data Concentrator) linkage data of the PMU. Enter the H/W (hardware) information of the RTDS communication card (e.g. GTNET card) for creation into the control unit 300.

FIG. 2 is a flowchart shown to explain the operation of the data input unit 100 in FIG. 1. As shown in FIG. 2, the data input unit 100 inputs PMU installation bus information to the control unit 300. Do it (S101).

Here, the PMU installation bus information is information on which of the domestic 154kV or higher energy centers to install the PMU. For example, in power system data, energy centers are indicated by numbers, and the bus number such as 1020, 1200, and 1250 is input. .

Additionally, the data input unit 100 inputs RTDS DFT data (i.e., RTDS draft data) and DTP data (i.e., transmission line configuration relationship data) to the control unit 300 (S102).

That is, the data input unit 100 inputs whole-system DFT data (i.e., RTDS draft data) and DTP data (i.e., transmission line configuration relationship data) generated in RTDS to the control unit 300. At this time, DFT data and DTP data are text-based raw data.

Additionally, the data input unit 100 inputs H/W (hardware) information of an RTDS communication card (eg, GTNET card) to the control unit 300 (S103).

In other words, the RTDS communication card (e.g. GTNET card) that generates PMU data in RTDS uses a unique IP for each individual card. Additionally, since the RTDS communication card is connected to a specific port of a specific RTDS operation card (e.g. PB5 card) via an optical cable, the H/W information must be entered accurately to operate properly.

FIG. 3 is an example diagram shown to explain an example of inputting H/W information of the RTDS communication card in FIG. 2, and the H/W information is used when inputting PMU data to the control unit 300 in the PDC. do.

FIG. 4 is a flowchart for explaining the operation of the bus bar and transmission line connection relationship determination unit of the RTDS of the control unit 300 in FIG. 1.

The RTDS busbar and transmission line connection relationship determination unit 310 analyzes (or determines) the location (e.g. rack) of the busbar where the PMU will be installed in the RTDS DFT data based on the data input from the data input unit 100. (S201), analyze the connection relationship of the transmission line connected to the busbar (S202), activate the RTDS transmission line current channel and define the name (S203).

FIG. 5 shows in more detail the operation of the RTDS busbar and transmission line connection relationship determination unit 310 in FIG. 4 to analyze (or determine) the location (e.g., rack) of the busbar where the PMU is to be installed from the RTDS DFT data. This is a flow chart to explain.

Referring to FIG. 5, the step (S201) of analyzing (or determining) the position of the busbar (e.g., rack) where the PMU will be installed in the RTDS DFT data based on the data input from the data input unit 100 is the busbar of the RTDS. And the transmission line connection relationship determination unit 310 reads the RTDS DFT data and analyzes the bus bar location (S301), and analyzes the PMU installation target bus bar and RTDS rack location (i.e., in which rack the bus bar to which the PMU is to be installed is located). (S302), but when all analyzes are completed (example of S303), the information (i.e., rack information about the PMU installation bus) is converted into a database and stored (S304).

FIG. 6 is a flowchart to explain in more detail the operation of the RTDS busbar and transmission line connection relationship determination unit 310 in FIG. 4 to analyze the RTDS busbar and transmission line connection relationship.

Referring to FIG. 6, the RTDS busbar and transmission line connection relationship determination unit 310 extracts node information from DTP data among the data input from the data input unit 100 (S401) and creates two types of branches. After searching for information (e.g., RL line, T-line) (S402), the transmission line information (T-line) retrieved in step S402 is matched with the bus information (i.e., node information) retrieved in step S401 ( S403). And when the connection relationship analysis for the searched transmission line information (T-line) is performed and the connection relationship analysis for the transmission line information (T-line) is completed (example in S404), the transmission line information connected to each busbar ( T-line) is converted into a database and stored (S405).

In other words, only node information and T-line information are classified from RTDS transmission line information data, and the connection relationship between node information and transmission line information (T-line) is analyzed to determine the relationship between bus lines (i.e. node information) and transmission lines. Convert to DB and save.

Meanwhile, in FIG. 4, the step of activating the RTDS transmission line current channel and defining the name (S203) involves activating/deactivating the code for the current monitoring channel of the transmission line information (T-line) of the PMU installation transmission line. Activate the current monitoring element and define and enter the current channel name as an independent name to avoid conflicts with other transmission line names.

FIG. 7 is a flowchart for explaining the operation of the PMU required number determination unit 320 for each rack of the RTDS in FIG. 1.

For reference, the number of racks where the PMU can be installed varies depending on the H/W configuration of the RTDS communication card (e.g. GTNET card). Therefore, check the number of PMUs required for each rack, and if the number of PMUs is insufficient in a specific rack, export the bus voltage and line current channels to another rack, and import the bus voltage and line current from a rack with a sufficient number of PMUs. ) receive. Finally, the connected PMU information is converted into a database and stored.

The RTDS required number of PMUs per rack determination unit 320 analyzes the required number of PMUs per RTDS rack (S501). In other words, the number of PMUs installed varies depending on the number and configuration of RTDS communication cards (e.g. GTNET cards). Therefore, we analyze how many PMUs can be installed in the nth rack.

Then, the required number of PMUs for each RTDS rack is analyzed, and if it exceeds the number of PMUs installed for each rack (example in S502), the remaining number of PMUs for each rack is analyzed (S503).

For example, one PMU is required per transmission line (T-line). Therefore, while analyzing the number of PMUs required in the nth rack, the number of available or insufficient PMUs is calculated, and the number of additional available PMUs is calculated for each rack.

In addition, the RTDS's determination unit 320 for the required number of PMUs per rack generates voltage and current data transmission modules in the remaining racks where the PMUs are installed (S504). In other words, so that the PMU can transmit voltage and current data to an available rack, the busbar voltage and line current values are transmitted using the RTDS data export and import modules (not shown). Create a module that does

In addition, the RTDS's required number of PMUs per rack determination unit 320 checks whether installation of the PMU installation target location is complete, and when installation of the PMU installation target location is completed (example of S505), the number of PMUs required for each rack and the mother ship name are determined. (i.e., the name of the mother ship) is converted into a database and stored (S506). In other words, check whether PMUs are installed on the busbar to be installed and all transmission lines (T-lines) connected to the busbar, and store the PMU configuration information for each rack in the DB.

In step S502, the required number of PMUs per RTDS rack is analyzed, and even if the number of PMUs installed per rack is not exceeded (No in S502), the number of PMUs installed per rack and the name of the bus (i.e., the name of the bus) are stored in a database (S506) ).

Meanwhile, if the installation of the PMU installation target location is not completed in step S505 (No in S505), the required number of PMUs per rack in the RTDS determination unit 320 displays the PMU non-installation target location according to H/W constraints ( S507). In other words, if there is a place where the PMU is not installed even though all available PMU channels are used, this is displayed (i.e., the target location where the PMU is not installed) is displayed and the user is notified.

FIG. 8 is a flowchart for explaining the operation of the PMU module generator 330 in FIG. 1.

Referring to FIG. 8, the PMU module creation unit 330 performs PMU module creation in RTDS (S601). In other words, create a PMU module in the RTDS draft and define the settings in it as RTDS H/W configuration. One PMU module (based on PMU_v4) can create 8 PMUs, and n are added at a time depending on the H/W configuration.

Additionally, the PMU module generator 330 defines the PMU voltage, current channel, and port (S602).

That is, when the number of PMUs is defined in step S601, detailed properties for each PMU are specified. In particular, the PMU H/W ID Code and port number for each rack must be configured independently, so enter them to avoid duplication. Here, the bus voltage and line current use the results from the bus bar and transmission line connection relationship determination unit 310 of the RTDS and the PMU module generation unit 330.

And the performance result of step S602 is converted into a database and stored.

Additionally, the PMU module generator 330 stores new DFT data (i.e., draft data) and DTP data (i.e., transmission line configuration relationship data) (S603). That is, the PMU module and PMU properties store completed DFT data and DTP data.

In FIG. 1, the PMU H/W information connection unit 340 is a device that can store, monitor, and analyze PMU data generated by an RTDS communication card (e.g., GTNET card). Properties must be linked.

Accordingly, it is configured using the ID for each PMU defined in step S602 and the RTDS communication card (e.g. GTNET card) H/W IP information input in step S103. When the PMU H/W information connection unit 340 is activated, PMU data generated in RTDS is transmitted to the PDC, and PMU data storage, analysis, and event recording can be performed according to the functions provided by each PDC.

The data output unit 400 outputs all information stored in a database by the control unit 300.

As described above, this embodiment improves the problem of limitations in analysis because hundreds of gigabytes of data are acquired per day from 50 PMUs installed in the field, but there are not many records of failure events in the system. It is possible to store various events that occur when a specific line failure, busbar failure, or equipment failure occurs, and has the effect of systematically establishing response plans for the actual system through the results of prior review. In particular, since PMU data is high-precision data acquired at a cycle of 240 sampling per second, this data can be acquired and used as auxiliary control in the event of an error in HVDC or FACTS power facilities. In particular, although it is impossible to test on actual field facilities, this data Through the example, using a replica controller such as HVDC, TCSC, or FACTS connected to RTDS has the effect of enabling various tests. In addition, currently 50 PMUs are installed concentrated in the metropolitan area, Gangwon, and Chungcheong regions, but in the future, PMUs will be expanded and distributed nationwide in order to monitor grid frequency, power grid inertia, and voltage volatility in accordance with the increase in renewable energy. Since this has to be done, this embodiment has the effect of allowing it to be usefully used when selecting important monitoring locations (priority locations for PMU installation).
