Description

Partial discharge diagnosis training device {APPARATUS FOR PARTIAL DISCHARGE DIAGNOSIS TRAINING}

The present invention relates to a partial discharge diagnostic training device, and more specifically, to a partial discharge diagnostic training device that allows partial discharge diagnostic training to be performed by accessing a partial discharge diagnostic training platform.

In general, a substation consists of a transformer and a switchgear as the main equipment. It has changed from the old outdoor steel switchgear type and uses sulfur hexafluoride (SF6 gas), which has excellent insulation performance and arc extinguishing ability, as an insulator, and various types of equipment are contained within the metal enclosure. A gas insulated switchgear (GIS) with a built-in substation device has been installed and is in operation.

These gas insulated switchgear (GIS) are used in the event of internal insulation breakdown or failure due to sudden increase in load, external ground fault, or abnormal voltage generated during switching due to the trend of high voltage and large capacity in power facilities. Since this is extensive and requires a long recovery time, it can be said that the ripple effect problem is very large not only in the industrial sector but also in the overall economic aspect of the country.

As there have been limitations in directly observing or inspecting the soundness or abnormality of GIS from the outside, much research and technology development has been conducted for internal diagnosis. Diagnostics that can diagnose the condition have been introduced and are used to check the soundness of equipment and prevent breakdowns.

Among them, GIS preventive diagnosis technology, which is an effective diagnosis technology for diagnostic reliability and abnormal occurrence points, measures electromagnetic waves generated during microdischarge due to abnormal conditions occurring inside the gas insulated switchgear (GIS), that is, partial discharge signals in the UHF band. , When an abnormal signal occurs, it is a technology that analyzes the partial discharge pattern for the abnormal phenomenon and diagnoses the cause. Heavy electrical equipment companies or power companies build their own partial discharge system or expand related diagnostic personnel, and directly conduct on-site diagnosis. We are constantly checking the soundness of our facilities and, furthermore, in situations where professional diagnosis is required, we receive support from personnel with the company's professional skills to provide diagnosis and improve our technology for preventive diagnosis. We also operate our workforce efficiently. For this purpose, partial discharge diagnosis technology is becoming more advanced, including systemizing preventive diagnosis, comprehensive management from a remote location, and determining abnormal conditions after diagnosis.

However, even if a series of comprehensive systems are established, the determination of whether there is an actual abnormality in the field equipment is a situation where diagnosis personnel are mobilized to conduct a detailed diagnosis on site and then go through a procedure to make a final judgment on the abnormal condition of the related equipment. If diagnosis of field facilities is not performed based on personnel's diagnostic skills, judgment ability, and understanding of field facilities, it will result in inefficient and uneconomical facility operation.

In addition, the manpower for on-site equipment diagnosis will vary depending on the power company, but there are limitations in learning diagnostic technology and applying it to the field because it relies on senior personnel or acquires related knowledge and skills through textbooks. It is difficult to improve diagnostic technology and have accurate judgment skills. There are problems that require a lot of time and effort.

Through the partial discharge editing unit 142, various partial discharge situations can be implemented for each user, and partial discharge diagnosis training can be performed in a desired partial discharge situation.

The partial discharge DB 143 contains basic data for activating partial discharge diagnosis on a web basis (e.g., layout, equipment, sensors, partial discharge situation, characteristic constant, tutorial for diagnosis in each partial discharge situation). etc.) are saved.

FIG. 2 is an exemplary diagram shown to explain the schematic operation of the partial discharge diagnosis training device in FIG. 1.

Referring to FIG. 2, the partial discharge diagnosis training device performs a process of setting up the diagnostic environment for diagnosis (S101 to S105) and a process of determining, outputting, and storing the diagnosis result when the user performs the diagnosis (S201 to S205). .

First, the diagnostic environment setting process (S101 ~ S105) requires the user to enter basic user registration data (registration information) for use of the training device (S101), and to select each mode (e.g. 1:N mode, N:N mode, self-registration) mode, etc.) (or by partial discharge diagnosis training mode) performs the specified operation for each mode according to the selection (S102). In addition, the partial discharge diagnosis environment (or partial discharge situation) is edited according to the operation specified for each mode, and calculations are performed considering the partial discharge situation arrangement and installation characteristic constants according to the set mode (S103), and the partial discharge diagnosis environment (partial discharge situation) is edited according to the operation specified for each mode. When the situation) is established and the accuracy for performing the diagnosis through self-verification and diagnosis is satisfied, diagnosis start information is transmitted and output to the user console (S104, S105).

The process of determining, outputting, and storing the next diagnosis result (S201 to S205) is when an authorization signal (i.e., diagnosis start information) is received for the diagnosis processing unit 141, the user is connected to the partial discharge diagnosis training device. Partial discharge diagnosis training is performed based on the information (e.g., layout of equipment, sensors, etc.) (i.e., partial discharge situation) transmitted to the screen of the console (S201), and at this time, the user selects each sensor and receives the signal. When partial discharge is diagnosed through size, waveform, etc., it is transmitted to the server unit 130 (S202), and the server unit 130 (in particular, the diagnosis processing unit 141 of the partial discharge diagnosis training processing unit 140) The partial discharge diagnosis results performed by the user are determined through sensor-specific information (e.g., signal size and waveform, etc.) (S203), and at this time, the user's partial discharge diagnosis results are converted into data with guaranteed accuracy (i.e., verified partial discharge results). The decision is made by comparing with the diagnosis result data).

The results of the comparison judgment confirmed in this way are output as feedback to the user (S204) and stored in a storage system (e.g., user console, user account on the server, etc.) according to the user's conditions for use (S205).

Hereinafter, with reference to FIG. 3, the components of the partial discharge situation (or partial discharge diagnosis environment) previously stored in the partial discharge DB 143 will be described.

Here, each component for setting the partial discharge situation (or partial discharge diagnosis environment) is stored in the layout DB 143a. At this time, each component may be stored in an individual DB or may be stored collectively in one DB. .

First, the layout DB is a component for creating a partial discharge diagnosis environment (or partial discharge situation) within the partial discharge diagnosis training device, and is comprised of characteristic constants, signal transmission sensors, and signals related to the equipment shape such as GIS, TR, and CABLE UNIT. Includes receiving sensor, partial discharge DB, and noise and weather DB.

Here, the equipment shape is classified by unit, and the attenuation characteristic constant is registered by matching a pre-specified value for each equipment. The signal transmission sensor includes a control function that can adjust electromagnetic wave diffusion characteristics and signal strength depending on the sensor placement position. The signal receiving sensor has the ability to absorb electromagnetic waves depending on the placement of the sensor and has a 100% absorption ability after partially attenuating the transmitted signal size. In addition, the noise and weather DB generates a signal (noise propagation signal) that can be generated externally in the external environment and may cause interference to the GIS receiving sensor (i.e., signal receiving sensor). is given, and a signal (noise radio signal) is given under the assumption that meteorological conditions may also cause interference to the GIS receiving sensor (i.e., signal receiving sensor) by providing some characteristic constants.

The partial discharge situation (or partial discharge diagnosis environment) using the components stored in the layout DB 143a is created in advance (i.e., pre-set created) (S301, i.e., preset by default when manufacturing the partial discharge diagnosis training device). generated) may be stored in the preset big data DB 144.

For example, a pre-designated GIS layout is automatically created according to the quantity of equipment, and signal sending sensors and signal receiving sensors are automatically arranged according to the quantity of equipment by giving conditions that take into account field conditions. At this time, the preset big data DB 144 can be generated as many cases as the number of cases that can occur by randomizing the partial discharge elements, noise, and weather combination elements according to the arranged layout.

Meanwhile, this embodiment can create a partial discharge diagnosis environment (or partial discharge situation) using field equipment for each user (i.e., custom-set creation). In other words, the user randomly specifies the layout of the components such as the desired equipment (S401) and sets the characteristic constants (e.g., transmission signal strength, phase, position, signal attenuation adjustment, etc.) for each component (S401). S402), the layout that obtains diagnostic accuracy and reliability through the simulation process is registered as a custom set temporary DB (145) or a custom set permanent DB (146) depending on the usage conditions.

For example, the partial discharge diagnosis environment (or partial discharge situation) custom set set by the user is unconditionally stored in the custom set temporary DB (145), and if repeated use is decided in the future, it is registered in the custom set permanent DB (146). .

In this way, this embodiment improves the training effect by allowing the user to directly create various partial discharge diagnosis environments (or partial discharge situations) for partial discharge diagnosis training.

In addition, the above components can also be added.

For example, when a new type of equipment different from the existing built-in equipment type occurs due to the trend of diversification and enlargement of electric power equipment, the user can add a component to the layout DB 143a, and the added component at this time Match the equipment type and characteristic constants, set the partial discharge type (i.e., partial discharge diagnosis environment) for these newly added components, and apply (or register) them to the partial discharge diagnosis training device according to this embodiment. make it possible In addition, it is also possible to additionally apply (or register) data containing characteristic constants for sensors, weather, noise, etc.

Hereinafter, the partial discharge diagnosis training mode will be described with reference to FIG. 4.

The partial discharge diagnosis training mode can be varied depending on the user's conditions and how to use the partial discharge diagnosis training device. Representative modes include 1:N, N:N, and self-mode.

First, 1:N mode refers to a mode in which one instructor conducts group training. When selecting the mode, the partial discharge situation (i.e., partial discharge diagnosis environment) is set (or customized) through the instructor's user console (S501). (S502), all partial discharge diagnosis training is comprehensively controlled (S503), and the trainer can participate in training in the partial discharge situation (i.e., partial discharge diagnosis environment) created by the instructor (S504). .

The following N:N mode is a mode in which an unspecified number of people can access partial discharge diagnostic training and receive diagnostic training, and the user can access the virtual training address assigned to the partial discharge diagnostic training device (i.e., partial discharge situation (i.e., partial discharge You can connect by receiving an address to access a web space where you can train the diagnostic environment (S505) and participate in training simultaneously through connection between multiple user consoles (S506, S507). In this mode, there is no control (or control) entity, but a representative can be set up for the operation and progress of the device.

For reference, in N:N mode, if there is no representative, one representative can perform the operation and progress of the device through consultation with the trainers.

The next self mode is a mode in which an individual accesses for training to improve work capabilities and diagnostic skills. When selecting the mode, an address is assigned for the individual, and other people are unable to access (S508) . And you can participate in partial discharge diagnosis training in a partial discharge diagnosis environment created by a preset or custom set (S509).

For reference, in self-mode, the custom environment (individual partial discharge diagnosis environment) created by the user can be saved through the save function, and then the partial discharge diagnosis environment (or partial discharge situation) can be recalled and recycled (retrained) later.

Hereinafter, the partial discharge editing unit 142 will be described with reference to FIG. 5.

The partial discharge editing unit 142 can set (create) a partial discharge diagnosis environment.

In the self-mode, a custom environment (individual partial discharge diagnosis environment) can be created and stored. At this time, when setting up (creating) the partial discharge diagnosis environment, the arrangement of each component (e.g. equipment, sensor) and the characteristic constants for each component (e.g. signal sensitivity, signal intensity, signal size, etc.) can be arbitrarily adjusted by the user. It is possible and freely editable.

Referring to FIG. 5, through the interface screen of the partial discharge diagnosis training device output on the user console, the user can access GIS equipment that reflects characteristic constants for each unit such as GIS, TR, and CABLE, and equipment connected to this GIS equipment. are retrieved from the database (DB) and placed (S601), and corresponding sensors (i.e., sensors for transmitting/receiving partial discharge signals and sensors for detecting noise) are placed according to the quantity of equipment and assigned unique numbers (S602). .

Once the arrangement of the units and sensors is completed as described above, the partial discharge diagnosis training processing unit 140 verifies the suitability of the arrangement of the equipment and sensors.

Additionally, the user sets the partial discharge type (or partial discharge situation) and sensitivity for each sensor (S603). In other words, the user sets the type of partial discharge stored in the DB by using an appropriate sensor among the deployed transmitting sensors, adjusts the characteristics of the generated signal such as the size of the waveform and the generation cycle, and arbitrarily sets the receiving sensitivity for each sensor.

Accordingly, the partial discharge diagnosis training processor 140 calculates the attenuation amounts of the transmitted and received partial discharge signals in the unit section (S604).

That is, when the partial discharge signal generation and other sensitivity settings for each partial discharge type are completed, the partial discharge diagnosis training processing unit 140 calculates the unit, sensor, and other specified requirements, and focuses on the attenuation amount of the partial discharge signal for each section of the units. A customized calculation is performed, and additionally, an interference signal (or noise signal) is also calculated.

In addition, the partial discharge diagnosis training processing unit 140 performs a self-verification process to determine whether partial discharge judgment requirements considering reasonable and appropriate signal strength and reception sensitivity can be satisfied for the calculated result values for each sensor (S605) .

That is, the partial discharge diagnosis training processing unit 140 performs self-verification to determine in advance whether there is a partial discharge based on the partial discharge type (or partial discharge situation, partial discharge diagnosis environment) set by the user and the sensitivity of each sensor. will be.

After the above verification, if it is determined that an environment with reliability and accuracy for partial discharge diagnosis judgment has been created, recalculation is performed or calculation is completed according to the verification result (G/F) (S606), and a new partial discharge type (or As a partial discharge situation, partial discharge diagnosis environment), transmission preparations for storage in the partial discharge DB 143 are performed (or stored in the partial discharge DB 143) (S607).

Hereinafter, with reference to FIG. 6, a process in which a user performs partial discharge diagnosis through a partial discharge diagnosis training device will be described.

When a user accesses the partial discharge diagnosis training device, the partial discharge type (or partial discharge situation, partial discharge diagnosis environment) stored in the partial discharge DB 143 is loaded (or loaded) into the user console through self-verification as described above. After adjusting the settings (i.e., settings of facility layout or sensor characteristic constants), the output is output (S701, S702). At this time, a diagnostic technology guide (or tutorial information) for the partial discharge type (or partial discharge situation, partial discharge diagnosis environment) may be included and output (S703).

Once a series of settings for the partial discharge type (or partial discharge situation, partial discharge diagnosis environment) are completed as described above, the user starts partial discharge diagnosis (S704).

Then, the user's partial discharge diagnosis results are transmitted to the server unit 130 (particularly the partial discharge diagnosis training processing unit 140) (S705), and the partial discharge diagnosis training processing unit 140 performs self-verification in advance with the user's partial discharge diagnosis results. Compare the judgment data stored and determine whether they are the same (S706).

The determined result is transmitted to the user console (S707) and stored in the database (i.e., partial discharge DB 143) of the partial discharge diagnosis training processing unit 140, and then the partial discharge diagnosis training is ended (S708).

At this time, when the judgment result is transmitted to the user console (S707), judgment data stored in advance through a self-verification process is additionally transmitted to the user console so that the user can check (or learn).
