The present invention relates to a complete stereoscopic visualization system and visualization method for power system monitoring using holography, and more particularly, to implement power system components such as buses, lines, generators, and transformers as holograms and receive system data in real time to operate the system. By expressing the system operation status in a space where the user can feel the same as the actual environment, the electric power using holography enables the operator to immediately monitor detailed system information such as voltage and frequency to respond immediately to the system's disturbance and accident. A system monitoring full stereoscopic visualization system and visualization method.

When monitoring hundreds, thousands, or tens of thousands of situations with hundreds of bus lines, such as the current power system, a system that can express the status of the system operation in a space that feels like a real environment is vulnerable. The current tidal current analysis program (PTI's PSS / E), which is currently used for power system analysis in Korea, is very poor in the graphic environment.In the case of foreign countries, as mentioned above, new graphic expression techniques have recently been installed. Programs (such as the Power world Simulator) are emerging.

However, these techniques have early limitations that have not yet been established, and have been developed to develop new three-dimensional complete visualization systems and visualization methods for power system data that are more intuitive, easier and clearer, and are useful for both system analysts and beginners. It is desired to be able to use it.

In addition, when there is a so-called north-east algae problem in which power moves from the power generation stage to the demand stage in a characteristic power system such as in Korea, it is important to consider the current flow and phase angle of the line rather than the magnitude of the voltage. It is extremely difficult to apply the same domestic and foreign methods to feel the same as the actual environment.

Figure 1 shows a power system monitoring system according to the prior art. As can be seen in Figure 1, the power system monitoring system according to the prior art monitors based on the flow rate of the transmission line through the grid system (Rear Project) of the power supply operation room 765kV ( Operators determine and monitor changes in the system through visual information of color classifications such as purple), 345kV (light blue), 154kV (white), and generator (green). Such information provides static information due to system changes, but lacks dynamic information and response to emergency situations such as accidents. In particular, it is necessary to show visually the situation of system disturbance such as an accident so that the system operator can help to make a quick judgment for coping. In addition, detailed information such as voltage, frequency, hydropower system, etc. of the system should be monitored through separate information.

2a to 2d show another power system monitoring system according to the prior art.

Figure 2a is a power world simulator (Power World Simulator) of the US Power World Corporation (Power World Corporation), and most of the representation is limited to two-dimensional, although some trial attempts to three-dimensional representation, three-dimensional representation In terms of the height of a cylinder, the magnitude of the voltage is expressed, but the phase cannot be represented.

FIG. 2B illustrates a simulator developed by the University of Tokyo, Japan, which represents power system dynamic analysis data using a sphere. The sphere is represented by the magnitude of the voltage and the phase is expressed by the vertical movement of the sphere. However, this also has a problem that it is difficult to grasp intuitively because it is not visual in expressing a number of mother ships.

Figure 2c shows another power system monitoring system according to Japanese Patent Laid-Open No. 2000-50531. The monitoring system according to FIG. 2c provides a display method that enables an intuitive analysis of the system state by simultaneously expressing the power system configuration and various physical quantities. Such a monitoring system expresses the overall system configuration in a three-dimensional rectangular plane, so that the three-dimensional configuration is expressed in three dimensions. There is a problem that it is difficult to grasp intuitively because it is not visual.

Figure 2d shows another power system monitoring system according to National Patent Publication No. 465021 developed by the inventor of the present invention. Monitoring system according to Figure 2d can be obtained in a short time high efficiency by expressing the intuitive and easy analysis even for beginners as well as experts in analyzing hundreds to tens of thousands of various power system. In other words, it effectively expresses the magnitude, phase angle, and effective / invalid power flow of the line, which are difficult to express simultaneously, in three-dimensional form effectively, and applies a special form of three-dimensional modeling and various kinds of three-dimensional perspectives. It can be easily observed according to. In addition, it is especially useful when there are a large number of buses and tracks or when reviewing a large number of cases, and the analysis data is effectively processed not only in a stable static state but also in a rapidly changing dynamic state. It is modeled so that analysis output data of analysis program PSS / E can be used as it is. However, there are drawbacks to expressing many motherships that they are not completely visual to feel the same as the actual environment.

That is, there is a limitation in that the prior art shown in FIGS. 2A and 2D cannot be monitored to feel the same as the actual environment.

Accordingly, the present invention is to solve all the disadvantages and problems of the prior art as described above, monitoring the power system using holography that can express the system operating state in a space where the operating status of the system can feel the same as the actual environment. It is an object to provide a complete stereoscopic visualization system and visualization method.

Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical idea of the present invention, various equivalents that may be substituted for them at the time of the present application It should be understood that there may be water and variations.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 3A to 3G are for explaining a power system monitoring full stereoscopic visualization system and visualization method using holography according to an embodiment of the present invention.

3A shows an example of a stereoscopic image according to an embodiment of the present invention. The three-dimensional image for monitoring the power system using holography according to the present invention is expressed in three-dimensional stereoscopic image for the main power system components such as bus, line, generator, transformer. Figure 3a is an example of the three-dimensional image of the bus and the transmission line of the main elements of the power system. The 3D image of the bus and the transmission line as shown in FIG. 3A provides a practical feeling to the system operator and makes an immediate situation recognition and prompt judgment regardless of the operator's experience as an immediate change of the 3D image in case of a system accident such as a disturbance. It is to provide information that can be.

The stereoscopic image according to the present invention expresses the current situation of the power system as a 3D holographic stereoscopic model, each of which implements the corresponding data as shown in FIG. 3A, and a bus and a line in a space where the power system operator can monitor the system. While observing the systematic implementation implemented with 3D holographic stereoscopic models, the detailed data can be viewed and the current state can be monitored through the touch method using the WIMP system. The specific implementation process from the model implementation using the hologram to the data display is as follows.

First, a 3D model is implemented using holograms for power system components such as buses and lines through positional information on power system components such as buses and lines. Each of the power system components implemented as a 3D model using a hologram is connected to each other through respective location information, and finally a hologram 3D stereoscopic image model of the power system components for a desired area range is generated. That is, a hologram 3D stereoscopic model for the components of the power system such as a generator and a transformer, as well as a 3D stereoscopic model of the bus and track using the hologram shown in FIG. 3A, is generated. It is connected to each other through location information to provide the system operator with a real feeling.

An embodiment of implementing a 3D model using the hologram of the present invention will be described in detail as follows. The implementation of the 3D model is to monitor the power system by implementing three-dimensional stereoscopic images of the main elements such as system bus and transmission line in the virtual studio using hologram. 3b shows a general example using a virtual stereo space. The present invention uses the virtual solid space as shown in Figure 3b and selects the components of the power system implemented by using the hologram to determine the current state and emergency of the system. These components of the power system can be implemented using a program such as 3D max. 3D max is a 3D animation-only software that models, colors, and moves objects (buses, power lines, etc.). FIG. 3C illustrates the implementation of a transformer as an example of an implementation example of a system element to be applied to a virtual stereo space using a 3D max program. In this way, objects of grid elements such as transmission lines and busbars are realized in three-dimensional stereoscopic images. In addition, the operation of the implemented virtual stereo space implements an image as shown in FIG. 3B by using a Real Time Virtual Set (VS2000) tool. The VS2000 system integrates a powerful graphics generator, multi-channel chroma key, mixer, multi-channel codec, live video input, 6-channel audio input / output, etc. in one system without any additional equipment. Using this system, virtual spaces can be operated, and the operator can monitor the system elements implemented in these virtual spaces and promote stable operation of the system.

Second, system data is received in real time from the Supervisory Control and Data Acquisition (SCADA) system. SCADA system is a widely used system for equipment, systems and solutions used to monitor and control remotely installed devices and equipment at other remote locations (central). SCADA system is designed for various purposes (e.g. system voltage, frequency, tidal current, active power, reactive power, hydropower system, etc.) and is very logical in response to the operational concept and function required by the consumer. It can be designed into various types of SCADA systems. In other words, the remote control using the SCADA system can establish a complex communication network by wireless, wired or mixed configuration while communicating with a powerful centrally installed computer from a simple structure such as a wire with a switch connected to a remote point.

Third, data is modeled through each power system component using real-time data from the SCADA system. As a modeling method of data, various methods that can be implemented as 3D stereoscopic images may be used. For example, as shown in FIG. 3D, the representation of the magnitude and phase of the bus voltage of the power system is modeled as a 3D stereoscopic image rather than a simple numerical representation. In other words, by modeling the phase and voltage in the bus bar in the shape of a lozenge and a straw, the phase is represented by the inclination and color of the lozenge and the voltage is represented by the height of the straw. If the phase is in the range between 0 and 180 °, the color of the lozenge is displayed in red. If the phase is in the range between 180 and 360 °, the color of the lozenge is displayed in blue. As shown in FIG. 3D, in the case of the bus line a, the voltage is V1 and the phase is 0 °, in the case of the bus line b, the voltage is between V2 and the phase 0 to 180 °, and in the bus line c, the voltage V3 and the phase is 180 °. The case is between 360 °. The phase angle can be modeled in various shapes such as triangles, ellipses, and circles as well as diamonds. 3D illustrates an example of modeling a tidal current and track capacity in a 3D stereoscopic image. The blue color means that the power capacity of the line is within the allowable range, the orange color means that the power capacity of the line is in the attention state, and the red color means that the power capacity of the line exceeds the allowable range. It means an alarm or warning condition. As shown in FIG. 3E, the steady state is shown in the line a, the caution state in the line b, and the alarm or warning state in the line c. The bands modeled on each track are expressed to move (flow) each track as the flow of the tidal stream. As shown in FIG. 3D and FIG. 3E, each object of the 3D stereoscopic image represented by color, shape, size, etc. using the hologram allows the system operator to easily grasp the state and operation status of the system.

Fourth, each power system component modeled using each model of the power system components and real-time data from the SCADA system is provided to the system operator through a graphical maintenance interface using the Windows, Icons, Menus and Pointing devices (WIMP) system. The detailed information of each area is examined and monitoring of the accident area is performed in real time. Although it is important for the system operator to monitor each power system component modeled using each model of the power system component and real-time data from the SCADA system, it is important to target each power system component implemented in 3D stereoscopic image. It is also very important to analyze the monitoring status of the system through the WIMP system.

The monitoring status analysis of the system using the WIMP system is performed as follows. Receive real-time data from the SCADA system for real-time monitoring, and at the same time, system stability analysis is performed online through a tool called Dynamic Security Assessment (DSA). The system's monitoring screen periodically calculates the data received online through the DSA tool and selects the object (for example, the mothership) that the system operator wants to monitor through the WIMP system. Through this, it is possible to monitor a result graph such as a QV curve (reactive power curve) shown in FIG. 3F, a PV curve (active power curve) shown in FIG. 3G, and the like. In addition, the monitoring of the system state through the WIMP system can monitor the various 3D curve graph shown in Figure 3h. In a conventional operating system (for example, the system shown in FIG. 1) for obtaining the result graph, simple voltage, frequency, current current value, etc. are monitored through simple two-dimensional, and the result shown in FIGS. 3F and 3G, etc. In order to view the graph, the results have been viewed in an offline analysis or in a separate system, whereas in the present invention, the result graph is online in a simple touch method (for example, a hand touch method) in object implementation using a hologram. The real-time data received can be calculated and viewed simultaneously, allowing the system operator to make quick judgments and actions. Monitoring the system status through the WIMP system provides more intuitive information as shown in FIGS. 3F to 3H using a data window or a visual graphic window. In addition, when the entire system is difficult to express in one region, a three-dimensional image is realized by dividing a window by region or by a certain range. After all, the WIMP system of the present invention refers to a comprehensive system for displaying and monitoring objects modeled using the virtual stereo space shown in FIGS. 3A to 3C.

Although the present invention has been shown and described with reference to the preferred embodiments as described above, it is not limited to the above embodiments and those skilled in the art without departing from the spirit of the present invention. Various changes and modifications will be possible.

Accordingly, the system and visualization method for monitoring the power system using holography according to the present invention may implement a stereoscopic image as a hologram of power system components (objects) such as buses, lines, generators, and transformers.

In addition, the system operation can be expressed in a space that can receive the system data in real time and feel the operation status of the system in the same way as the actual environment.

In addition, the operator can immediately monitor detailed system information such as voltage and frequency to enable immediate response in case of system disturbance and accident.

The WIMP system also simplifies the interface between the operator and the system, making it easy for non-experts or inexperienced users to access.

In addition, detailed data monitoring and analysis can be performed in the same space and information can be easily obtained.

It can also be used effectively for training, such as DTS.
