Description

A system and a method for analyzing electric power system data based on geographical information}

The present invention relates to a power system analysis system and method for analyzing geographic information-based power system data, and more particularly, to acquire power system information at a glance so that an operator (user) of the power system can recognize a nationwide system situation at a glance. The present invention relates to a system for calculating, outputting, and visualizing a degree of interference between a region and a region based on geographic data.

In general, the power system of all regions of Korea are connected by a ring network, so there is a fear that a point of failure will spread nationwide.

In order to solve the instability of the power transmission and distribution, the central power supply station of the power exchange is providing a facility that automatically monitors and controls the entire power system in Korea as a comprehensive automation system. In the automatic monitoring and control of the power system, the analysis of the power system checks the power and voltage status of a large number of generators or transformers in the entire area or in a specific area power system, and checks the status of the electricity generated by the generator. It refers to the process of simulating and analyzing phenomena such as what happens when the supply is changed, when the system is changed, or when the power transmission equipment or generator is stopped.

Based on this, the stability of the actual system is evaluated, and precautions are taken to secure the stability and reliability of the power system when an unstable situation is expected.

Precautionary measures here include constraint operation of the transmission network, adjustment of the system configuration, and installation of a system for preventing the occurrence of a failure.

Common items for evaluating the stability of a power system include fault capacity, overload, voltage stability, and low frequency fluctuations.

Although there are already various methods and programs for analyzing the power system as a conventional technology, the output screen provided to the operator (user) of the power system in such an analysis method or system provides a number form or a trend form for the current acquisition point. Only situation is possible.

3 to 5 also show a variety of monitoring screens for the analysis of the power system according to the prior art, as can be seen through these screens, the power system driver has a problem that the overall system situation is not recognized at once.

3 is a SCADA monitoring screen for power system analysis, Figure 4 is a land system disconnection diagram and GIS monitoring screen for analysis of the power system. 5 is a screen illustrating graph view monitoring of power information.

In the case of a tool that numerically simulates existing power system phenomena, the analysis results are presented to the user through a flat user interface, and after the user analyzes and understands the results, the user makes a simulation tool through his own judgment. It was common to modify the input to to observe the updated results again.

However, it can be said that this method of presentation has a drawback that the user cannot intuitively convey the analysis result or the characteristic to be analyzed. In particular, in the case of power systems, the amount of analysis results is vast, and there are many correlations between various analysis results, and there is a problem that the user has to reinterpret the presentation of primary data.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, embodiments of the present invention are not necessarily limited to the following examples.

6 is a block diagram illustrating a power system analysis system of geographic information-based power system data according to an embodiment of the present invention.

Referring to FIG. 6, a power system analysis system according to an exemplary embodiment of the present invention is largely composed of a database intensive server 100, a power system analysis server 200, and a user terminal 300.

The database intensive server 100 collects and stores power system information data of at least one power information acquisition point among nationwide or a specific region. An instruction to acquire power information data is instructed to acquire data capable of determining a predetermined power state in real time or at a reserved time at each acquisition point. The power information data may be a voltage, a current, an overload, a voltage stability, a transient stability, a failure capacity, a current, etc. of a transformer or a generator of the corresponding acquisition point, but is not limited thereto, and the power system driver may determine the power state. Standard items will be sufficient.

The power data acquired in geographically divided units may be collected and stored in a lower database for each unit, and these data may be finally collected by the database intensive server 100.

The power data collected by the database intensive server 100 are processed by the power system analysis server 200 and transmitted to the power system driver or the user terminal 300.

The components of the power system analysis server 200 are illustrated in more detail in the block diagram of FIG. 7. Referring to the block diagram of FIG. 7, the power system analysis server 200 includes a data processing and management module 201, an impact calculation module 203, a power system analysis module 205, a mapping module 207, and a database 209. ), And the power system analysis server 200 is connected to the map data 150 to process the data so as to map at a glance a state or a predetermined part of the situation for the power system analysis.

The data processing and management module 201 extracts a power system information data value of an acquisition point from the database intensive server in real time or at a preset time, selects an unacquisition point based on the acquisition point, and interprets the power system information. Manage the processing of data.

In the process of extracting the power system information data value, the data processing and management module 201 sorts by time tag, classifies and analyzes noise data and loss data, and stores reliable data in a database. 209).

The non-acquisition point may be separately designated by the user based on the acquisition point. Alternatively, the non-acquisition point may be automatically set, and a predetermined radius may be set based on the acquisition point, and a plurality of points may be selected for each bearing within the set radius. For example, if a specific substation in Taebaek is an acquisition point, a radius of 10km or 20km is set to set coordinates corresponding to the north, south, east and west directions within the section, and four points are selected as non-acquisition points. Since the corresponding azimuth coordinates of the specific substation in Taebaek are already acquired, estimating the azimuth coordinates of the non-acquisition point can be easily obtained through calculation. According to the degree of stability and rapidity of the system analysis, the user can freely select the number of unacquired points or the range of the predetermined radius.

It can be said that it is responsible for the processing and management of the overall power system information data, and stores the acquired data and the calculated data in real time or for each reserved time in the database 209.

The configuration module of the power system analysis server is not limited to the configuration and may be further added by various embodiments. A time control module for controlling the time for acquiring the power system information data for the acquisition point may be further added. . The data processing and management module 201 controls in advance with the time control module so as to reserve a time for obtaining power information or to acquire data at predetermined time intervals.

The influence calculation module 203 interpolates and estimates the power system information data value of the selected non-acquisition point based on the power system information data value of the acquisition point.

That is, the degree of influence between the acquisition point and the non-acquisition point is obtained by using the data having the same time tag collected in the data processing and management module 201. The influence degree may be calculated by referring to the distance of each region based on the data of the map data 150.

When the power system information data received at an acquisition point is a voltage value of a corresponding substation or a power plant, when an unacquisition point is determined, the voltage value of an unacquisition point is calculated from the distance values and weights between these acquisition points and the unacquisition point. .

An interpolation method is used for the calculation, and an inverse distance weighting (IDW) method may be used.

The IDW method uses the distance to the nearest acquisition point to find the value of the non-acquisition point. That is, the value of the unacquisition point is assumed to have a small effect on the non-acquisition point as the distance from the acquisition point becomes farther.

Where x is the coordinate value of the non-acquisition point, that is, the point to be estimated, d _i is the distance from the non-acquisition point to the surrounding observation point (acquisition point) i, x _i is the coordinate value at the acquisition point, and m Represents a weight. There is a relationship between the weight m, which is an optional value, and the influence of adjacent points, and the larger the value of weight m, the smaller the influence of further unacquired points.

The power system analysis module 205 determines a threshold range according to the power system information data value, and sets an analysis means partitioned with at least one or a combination thereof selected from among hue, brightness, saturation, and type for the range. Do this.

For example, the power system analysis module sets the critical range according to whether the power system information data is a voltage value or fault capacity, such as stable, dangerous, or high risk.

The number of compartments from stability to risk level can be set by the user.

Corresponding means such as hue, lightness, saturation and type are correspondingly set for the partition section thus set in each step of the critical range.

If the voltage range is divided as the data of the power system in 10 steps, the color corresponding to each step can be set. Preferably, the color of the danger section may be set to red or purple, and the color of the stable section may be set to yellow or green to facilitate the determination of the entire system when it is subsequently mapped on the map.

In addition, the power system analysis module 205 is equipped with a power system analysis algorithm such as a micro signal stability or a wide area voltage stability capable of calculating the current power system situation, the actual system analysis is performed.

The mapping module 207 maps the analysis means corresponding to the power system information data values for the acquisition point and the non-acquisition point to map coordinate data implemented in a two-dimensional or three-dimensional form. That is, when the power information data is a voltage value, voltage data of the corresponding acquisition point is acquired in real time or at a preset time through power information acquisition equipment installed all over the country, and voltage data of the non-acquisition point calculated based on the acquisition point. Map the voltage data at and on the national map. At this time, the mapping on the map means that the analysis means corresponding to each section of the threshold range to which the voltage data belongs, that is, the color of the corresponding section is mapped to the color on the map. According to an embodiment of the present invention, the map data value transmitted from the map data 150 associated with the mapping module may implement the map two-dimensionally or three-dimensionally.

Two-dimensional maps can be implemented in contours, surface maps, posts, vector maps, grid maps, and gridding methods. Can be.

On the other hand, the way the map is implemented in three dimensions may be a method such as Navigation, Wireframe maps, Contour, Volume rendering, 3D Effects, 3D Objects, and Movie maker.

The data results analyzed by the power system analysis module 205 are mapped according to a threshold value (contour reference value) of the corresponding range input by the user through the mapping module 207.

The database 209 included in the power system analysis server 200 is a means for storing all data derived from a power system analysis process, such as power system information data values for the acquired points and non-acquired points and mapped map coordinate data values. to be. The data analyzed in the power system analysis module 205 is stored and managed in the database 209.

(Example)

An embodiment in which power system information is mapped on a map through a power system analysis system of geographic information-based power system data of the present invention as described above is as follows.

For example, the data of the entire Korean map stored in the map data 150 may be a coordinate value in the form of a square grid of the entire Korean map based on a KATECH coordinate system. The cell size of a single Grid of the map can be 4000m * 4000m. In general, the catech coordinate system is a unit of meter, and x, y coordinates (0,0) to (4000, 4000) used in the system of the present invention correspond to a single grid size.

When voltage values are transmitted as power information data of a power plant or substation acquired through the database intensive server 100, the unacquired points are obtained by using the IDW interpolation method corresponding to Equation 1 based on the voltage values of these specific acquisition points. Calculate the voltage value of.

A screen visualizing the influence of the non-acquisition point based on the acquisition point in grid coordinates according to an embodiment of the present invention is illustrated in FIG. 9.

Referring to FIG. 9, the value of the weight m that can visually show the corresponding information of the system of the present invention is calculated as 2, and the influence degree is calculated and expressed only up to a grid at a distance of 50000 m from the acquisition point.

In an embodiment of the present invention, the map coordinate data is represented in the form of a grid, and the mapping of the power information data values of the corresponding acquisition point and the non-acquisition point is illustrated, but the present invention is not necessarily limited thereto. Depending on the color gradation can be mapped.

In one embodiment of the present invention, the contour technique is used to display the color of the grid of the map coordinates. The voltage values of the acquisition point and the non-acquisition point are mapped to the map grid in color so that the danger zone can be visually monitored immediately.

The color display of the grid depends on the value of the voltage value, which is the power information data of the acquisition point and the non-acquisition point.

In the table below, the means of interpretation of the power information data is classified by color, but is not limited thereto. The brightness and saturation level may be divided by one color, and may also be classified into various types of patterns filled with dots, solid lines, and dotted lines. Of course it can.

Preferably, it is convenient to distinguish the colors into several for easy judgment of the user.

Max correction value (threshold value) (%) PU Analysis means (color) More than 120 1.2 or more Red 105 or more ~ less than 120 Greater than 1 to less than 1.2 Orange 95 or more ~ less than 105 1 (normal / stable) yellow 80 or more ~ less than 95 0.8 or more and less than 1 green More than 50 ~ less than 80 0.5 or more ~ less than 0.8 blue 5 or more ~ less than 50 Greater than 0 and less than 0.5 Indigo Less than 5 0 Purple

The screen output as an embodiment of the power system analysis system of the present invention according to the above table is first expressed in red when a value of 184 kV or more, which is 120% of the threshold value of 154 kV, is acquired in the stability zone at the acquisition point having the voltage level of 154 kV, and 154 kV. When the 74kV value, which is 50% of the threshold value, is obtained, it is expressed in blue and mapped on the map. The voltage value at the point where the contour color is acquired based on the voltage level (reference examples 154kV, 345kV, 765kV) is calculated as a percentage of the reference value and mapped to the color of the analysis means of the corresponding range.

When the color as an analysis means corresponding to each voltage value is mapped to the map data according to the above table, it is transmitted to the user terminal and output. In some cases, the output method of the user terminal may be expressed as a gradation of a corresponding color.

The smaller the grid size, the more beautiful the screen can be displayed. However, since the time delay for the interpolation calculation and the screen representation is expected, the grid size is 4000 * 4000 optimized for the client specification of OS XP or above and memory 1GB or more.

As shown in Table 1, the acquisition point is spread nationwide, and the voltage value of the unacquisition point is calculated and mapped to a nationwide map as shown in FIG. 10, and may be output only in a specific region as shown in FIG. 11. FIG. 11 is a contour screen of a power system in Jeju, Korea, which is output through a power system analysis system of geographic information-based power system data according to an embodiment of the present invention.
