A method for providing a system for detecting a fault section by connecting an underground transmission line and a power device {Providing method for a distribution line fault recovery system}

The present invention relates to a method for providing a system for detecting a failure section by connecting an underground power transmission line and a power device, and more particularly, when a failure or failure occurs in a power device connected to a power transmission line, state information and fault section detection information are obtained in real time to quickly and It has been improved to support accurate detection of faulty sections of transmission lines, as well as providing sufficient and perfect protection against fires of power devices that automatically comprehensively monitor and detect power facilities for minimization of power outages and quick recovery from faults. It relates to a method of providing a system for detecting a faulty section by connecting an improved underground power transmission line and an electric power device so as to induce rapid evacuation of occupants by marking an evacuation route even in the dark and to prevent casualties through this.

The transmission system is a part of an electrical system that transmits electrical energy to consumers from a location where electrical energy is converted during transmission or the general power system, and rapidly transmits power received at a high voltage from a transmission line and delivers it to a substation or the like.

Such a transmission system consists of a voltage regulation system, a high-voltage transmission line, a power device, a low-voltage transmission line, and a lead-in line, and in some cases, a line from the primary power device to the power conversion system and related devices may also be included.

Since the transmission system exists over a very wide area, it is very difficult to expect that all transmission lines will always operate normally.

Therefore, it is acknowledged that there is always a risk that the power supply will be interrupted due to a failure anywhere in the vast power transmission line. It is necessary to quickly and accurately determine the point of failure so that power can continue to be supplied to parts other than the part where the failure occurred.

To this end, in the prior art, when a fault current occurs in a power transmission line, the operator and the power device manager in the field operate the power cut-off device to find the fault point where the fault current occurs, and the operator and the power device manager mainly use communication means to provide information on the accident point. It has been a common method to find fault points by exchanging them.

However, in the case of the above method, a lot of time and manpower is consumed, and as the recovery time increases, the failure time increases, which causes great inconvenience to power consumers. Accordingly, there has been a need for a method capable of improving the reliability of power supply and the quality of service to consumers by quickly identifying and recovering the location of the failure point in the event of an accident in the transmission line and shortening the failure time.

To this end, it receives the detection of a failure occurring on the transmission line through the detector and provides it to the line opening/closing controller to block or supply the power supplied from the power device by manipulating the opening and closing of the transmission line to repair the failure of the transmission line. A method has been proposed.

However, in the case of this method, there is a limitation in that it is difficult to analyze the comprehensive failure of the transmission line that is spread during failure management by determining only the location of the failure based on the received failure detection and repairing the failure of the wiring line.

In addition, in the case of power equipment, damage beyond imagination occurs when a fire occurs, so it is necessary to prevent the fire from spreading as well as extinguishing the initial fire.

The present invention was created to solve the problems in the prior art as described above, so that when a power device failure occurs, state information and failure management information are acquired in real time to support rapid and accurate detection of a failure section of a transmission line. In order to minimize power outages and recover from failures, it is possible to have sufficient and complete protection against fires of power devices that automatically and comprehensively monitor power facilities, and in the event of a fire, evacuation routes are marked even in the dark to induce quick evacuation of occupants. Its main purpose is to provide a method for providing a system for detecting a faulty section by connecting an improved underground power transmission line and a power device to prevent human casualties.

In addition, in the process of providing a transmission line failure management system, it is to provide a stable system in advance by managing the initial preparation process, such as handling problems, procedure violations, and errors such as combined installation, and discovering problems in advance.

In addition, in the installation process of the transmission line failure management system, it is to provide a system that can manage the intermediate process as a whole, such as handling problems, procedure violations, errors such as combined installation, and detect and respond to problems.

In addition, it is to provide a system that manages the operation process after installation of the transmission line failure management system to ensure operational reliability and stability and to perform an immediate response in case of an abnormality.

In addition, it is to provide a system that can clearly determine the possibility of a dispute by securing data of the process managed at various points in time to more clearly verify and identify problems and damages that may occur in the future.

In addition, as a means for managing a transmission line failure management system, it is to provide a system in which a management means having structural characteristics for managing and maintaining optimal operating conditions in various conditions is provided.

In addition, the means for the transmission line failure management system management is to provide a system that can stably perform the role of core situation management (eg, monitor, etc.) by protecting it from the external environment and pollution shock.

The problems of the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

The present invention provides a method for providing a system for detecting a failure section by connecting an underground transmission line and a power device, the method comprising: preparing a transmission line failure management system; and installing the power transmission line failure management system at a target location, wherein the power transmission line failure management system is installed around the target location.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 to 4, the method for providing a system for detecting a failure section by connecting an underground power transmission line and a power device according to the present invention includes a distribution information acquisition unit 120 installed in the power device 110, a shear processor ( 130 ), a power distribution control unit 140 , and a power device 150 .

The distribution information acquisition unit 120 is installed in each power device 110 to acquire status information and failure management information of the power device 110 when the power device 110 fails. The power distribution information acquisition unit 120 acquires state information including the power consumption and peak capacity of all facilities in the power device 110 just before the occurrence of a failure of the power device 110 .

In this case, the power usage is the actual power usage capacity of the facilities, and the peak capacity refers to the maximum power usage capacity of the facilities.

The distribution information acquisition unit 120 is a recovery participation capacity that combines the power consumption and peak capacity of the sound power device 110 facilities participating in the failure management and the capacitance according to the occurrence of a failure of the power device 110, the power device 110. Failure management information including the load capacity of the provided distribution feeders and the load capacity of the peripheral voltages (MTR) provided in the power device 110 is acquired.

At this time, the electrostatic capacity is the capacity generated by the fixed equipment when the power device 110 fails, and the recovery participation capacity is the individual use of all sound facilities that can participate in the failure recovery with respect to the capacity of the power device 110 failure and the failed facility. It refers to the total capacity of the peak capacity excluding the capacity.

The distribution information acquisition unit 120 determines the failure type through the state information obtained as described above, and determines whether failure management is possible inside the power device 110 through the failure management information, so that the failure management is impossible from the inside. If judged, the final power failure feeder is extracted.

To this end, the distribution information acquisition unit includes a failure mode determination unit 121 , a failure management determination unit 123 , and a final power outage feeder extraction unit 125 as shown in FIG. 2 .

The failure mode determination unit 121 determines whether a failure occurring in the power device 110 is a failure related to a peripheral voltage or a power trunk (BUS) or a distribution feeder through the state information.

The reason for determining this is that all other blackout accidents other than this are accidents that can be handled inside the power device 110 .

The failure management determination unit 123 compares the lowest minimum load capacity among the electrostatic capacity, the recovery participation capacity, and the load capacity of the distribution feeders to determine whether to manage the failure inside the power device 110 .

That is, the failure management determination unit 123 compares the capacitance and the recovery participation capacity, and when the recovery participation capacity is less than the capacitance, determines that failure management is impossible inside the power device 110 , and the capacitance and the distribution feeder (feeder) ) by comparing the minimum load capacity, when the minimum load capacity of the distribution feeder is smaller than the electrostatic capacity, it is determined that failure management within the power device 110 is impossible.

In this case, when the minimum load capacity of the distribution feeder is greater than the capacitance, the failure management of the power device 110 is possible without powering off the corresponding distribution feeder. The final electrostatic feeder extraction unit 125 extracts the final electrostatic feeder when it is determined that failure management within the power device 110 is impossible.

To this end, the final electrostatic feeder extraction unit 125 includes an electrostatic feeder existence confirmation unit 126, a first comparison unit 127, a second comparison unit 128, and a final electrostatic feeder selection unit ( 129).

The electrostatic feeder existence check unit 126 checks whether an electrostatic feeder exists in two or more of the peripheral voltages in the power device 110 .

When an electrostatic feeder exists in two or more peripheral voltages, the first comparator 127 sorts the restoration participation capacity of the healthy peripheral voltages participating in the restoration in order from the minimum to the maximum, and sets it sequentially with the capacitance. compare with

That is, the first comparison unit 127 compares the recovery participation capacity of the peripheral voltages arranged in order of magnitude until they have a value greater than or equal to the capacitance.

When an electrostatic feeder exists in one peripheral voltage, or when the recovery participation capacity of the peripheral voltages is greater than or equal to the capacitance as a result of the comparison, the second comparator 128 performs a distribution feeder in the corresponding peripheral voltage. Sort their load capacities in the order of minimum to maximum and sequentially compare them with the final capacitance.

That is, the second comparator 128 compares the load capacities of distribution feeders arranged in order of magnitude until they have a value greater than or equal to the final capacitance. In this case, the final capacitance refers to the capacitance generated when the power device 110 fails, which is offset by the recovery participation capacity of the healthy facilities participating in the recovery.

The final electrostatic feeder selector 129 selects the distribution feeder as the final electrostatic feeder, which is finally blackout, when the load capacity of the distribution feeder is greater than or equal to the capacitance as a result of the comparison.

The front end processor 130 collects the state information and the failure management information of the power device 110 obtained from the distribution information acquisition unit 120 , and information on the final power outage feeder, and transmits it to the distribution control unit 140 .

The power distribution control unit 140 determines whether the normally open point connection or the normal connection point is disconnected from the power transmission line based on the extracted final power outage feeder, so that the failure management of the power device 110 is performed.

To this end, the distribution control unit 140 includes an open point connection determination unit 14'1, a connection point separation determination unit 142, a load distribution determination unit 143, and a load redistribution determination unit 144, as shown in FIG. 4 . includes The open-point connection determining unit 14'1 determines whether the final electrostatic feeder can be restored through the regular open-point connection.

That is, the open point connection determining unit 14'1 determines whether to restore the final electrostatic feeder by connecting the normally open points, which collectively refer to a circuit breaker and a switch that are always open in the transmission line. At this time, if the recovery of the final power failure feeder is possible through the normal open point connection, the failure management is completed.

The connection point separation determining unit 142 determines whether the final electrostatic feeder can be restored through the regular connection point separation when it is determined that the final electrostatic feeder recovery is impossible due to the normal open point connection.

That is, the connection point separation determining unit 142 determines whether the final electrostatic feeder is restored by separating the normal connection points, which are commonly referred to as circuit breakers and switchgear, which are always off in the power transmission line. At this time, if recovery of the final power failure feeder is possible by disconnecting the connection point at all times, the fault section detection is completed by judging the load distribution for redistribution of the load on the transmission line. impossible

When it is determined that the final power outage feeder can be restored by the regular disconnection of the connection point, the load distribution determining unit 143 grasps the load distribution of the corresponding transmission line.

The load redistribution determination unit 144 determines whether to redistribute the transmission line load based on the identified load distribution, and if redistribution is possible, failure management is completed, and if not, failure management is impossible.

In addition, the present invention may further include a power device 150 that automatically and comprehensively monitors power facilities for minimizing power failure and promptly recovering from a fault. Thus, as shown in FIGS. 5 and 6 , when the power device 110 fails, state information and fault management information of the power device 110 are acquired ( S100 ).

In this case, the state information is information including the power usage and peak capacity of the power device 110 facilities just before the failure of the power device 110 occurs. The failure management information includes the capacity of the electric power device 110 according to the occurrence of a failure, the recovery participation capacity that is the sum of the power consumption and the peak capacity of the healthy electric power equipment 110 facilities participating in the failure management, and the distribution feeder provided in the electric power device 110 . It is information including the load capacity of the feeders and the load capacity of the peripheral voltages (MTR) provided in the power device 110 .

Next, the failure type of the power device 110 is determined through the state information (S110). That is, it is determined whether the failure occurring in the power device 110 is a failure related to the peripheral voltage or the power trunk (BUS) or the distribution feeder through the state information.

This is because other blackout accidents other than this are accidents that can be handled inside the power device 110 . Next, it is determined whether failure management is possible within the power device 110 through the failure management information.

First, by comparing the capacitance and the recovery participation capacity (S120), if the recovery participation capacity is larger than the capacitance, proceed to the next step (S121), and if it is small, the power device 110 because recovery is possible inside the power device 110 The internal failure management (S122) is completed.

Next, the capacitance and the lowest minimum load capacity among the load capacities of the distribution feeders are compared (S121). If the minimum load capacity is greater than the electrostatic capacity, proceed to the next step (S130), and if it is smaller, the power device 110 Since it is possible to recover from the inside, the failure management (S122) inside the power device 110 is completed.

Next, when it is determined that failure management within the power device 110 is impossible, the final power outage feeder is extracted.

First, it is checked whether an electrostatic feeder exists in two or more of the peripheral voltages of the power device 110 ( S130 ).

Next, when an electrostatic feeder is present in two or more peripheral voltages, the load capacities of the sound peripheral voltages except for them are sorted from the minimum to the maximum (M) (S131) and sequentially compared with the capacitance (S132) do.

At this time, if the restoration participation capacity of the peripheral voltages is greater than or equal to the capacitance, the process proceeds to the next step (S133). By summing up the recovery participation capacity, the current step (S132) is performed again.

Next, when an electrostatic feeder exists in one peripheral voltage or when the recovery participation capacity of the peripheral voltages is greater than or equal to the capacitance as a result of comparison, the load capacity of the distribution feeders in the corresponding peripheral voltage is increased from minimum to maximum. Sort them in order (F) (S133) and sequentially compare them with the final capacitance (S134).

At this time, if the distribution feeder load capacity of the corresponding peripheral voltage is greater than or equal to the final capacitance, the process proceeds to the next step (S140), otherwise, it returns to the previous step (S133) and the current distribution feeder load The current step (S134) is performed again by adding the capacity to the load capacity of the distribution feeder of the next sequence.

Next, in the previous step (S131), the distribution feeder (feeder) is finally selected as the final power outage feeder (S140).

Next, based on the extracted final power outage feeder, it is determined whether the normally open point connection of the transmission line or the regular connection point is disconnected, so that the failure management of the power device 110 is performed. First, it is determined whether the final electrostatic feeder can be restored through the normal open point connection (S14'1). At this time, if recovery is possible through the normal open point connection, the fault section detection is completed (S260), and if recovery is not possible, the process proceeds to the next step (S142).

Next, when it is determined that it is impossible to recover the final electrostatic feeder through the normal open point connection, it is determined whether the final electrostatic feeder can be recovered through the normal connection point separation ( S142 ).

At this time, if recovery is possible through the disconnection of the connection point, the load distribution of the transmission line is identified (S143), and whether or not the transmission line load is redistributed (S144) to complete the fault section detection (S160). If recovery is not possible, fault management Completely impossible (S150).

In addition, the power device 150 is a facility that automatically and comprehensively monitors power facilities for minimizing power outages and promptly recovering from faults, and as shown in the example of FIG. include Since the control box 152 is an important control unit performing a control function, it must always be protected from fire.

To this end, in the present invention, as in the example of FIG. 8 , a fire fighting tank 200 built into the ceiling of the space where the power device 150 is installed, and a drum housing fixed to the ceiling surface directly above the tip of the power device 150 ( 300) is included.

At this time, the fire extinguishing tank 200 is filled with a fire extinguishing liquid, and the fire extinguishing liquid is a liquid fire extinguishing agent used in a fire extinguisher having non-combustible properties, not general fire extinguishing water. In addition, the drum 310 is rotatably assembled inside the drum housing 300 . In addition, a drum motor 320 for rotating the drum 310 is fixed to one end of the drum housing 300 .

In addition, the drum 310 is configured such that a fire plate 330 is wound or unwound. The fire plate 330 is a known fire plate that is relatively thin and lightweight, and hinge links ( 340 is connected so that the fire plates 330 can be folded.

This is to make it easier to wind on the drum 310 . In addition, an injection pipe 350 is built on the fire plate 330 , and an injection hole 352 is formed in the injection pipe 350 , and fire extinguishing liquid is discharged through the hole formed to correspond to the front surface of the fire plate 330 . It is configured to be sprayed.

To this end, the injection pipes 350 are connected to the flexible hose 360 and configured to receive a fire extinguishing liquid, and the flexible hose 360 penetrates the fire plate 330 up and down to penetrate the inside of the drum 310 . through the rotary joint 370 formed at the other end. Then, the supply hose 380 extending from the fire fighting tank 200 through the rotary joint 370 is connected to the flexible hose 360 and connected to each other.

At this time, a part of the supply hose 380 is provided with a supply pump 390 , the supply pump 390 and the drum motor 320 are electrically connected to the controller 400 , and the controller 400 is a power distribution unit. It is electrically connected to the control unit 140 and is configured to drive and control them by quick control and control signals when a fire occurs.

Thus, when a fire occurs, the drum motor 320 is driven immediately and the fire plate 330 is spread out to cover the front of the power device 150 in the form as shown in the figure to primarily block the spread of the flame.

Then, the supply pump 390 is driven according to the control signal, and the valves not described are opened because it is a self-evident and well-known configuration, and the fire extinguishing liquid is supplied to the flexible hose 360 and the fire extinguishing liquid is ignited through the injection hole 352 . The plate 330 is ejected forward to help extinguish the fire at an early stage.

In addition to this, in the present invention, as shown in the example of FIG. 9 , a pair of posts 500 are further installed at intervals from both sides of the power device 150 .

In addition, a fire extinguishing fluid sprayer 510 is installed at the upper end of the post 500 , a fire suppression pump 520 is built-in at one side of the inside of the post 500 , and the lower end of the post 500 is a fire extinguishing liquid tank 530 . ) is inserted and fixed in a fixing groove 532 formed with a concave indentation on the upper surface of the fire extinguishing liquid tank 530 is disposed on the bottom surface, and the inlet port 534 is provided on one side of the upper surface of the fire extinguishing liquid tank 530. ), and the fire extinguishing liquid pipe 550 passes through the stopper 534 to supply the fire extinguishing liquid inside the fire extinguishing liquid tank 530 through the fire extinguishing pressure pump 520 to the fire extinguishing liquid injector 510 .

In this case, a post controller 560 for controlling the operation of the fire suppression pump 520 by receiving a signal from the distribution control unit 140 is further installed in the post 500 .

Accordingly, it is configured to minimize damage due to fire by double blocking and controlling the fire around the power device 150 when a fire occurs.

In addition, when a fire occurs, the interior may become dark as the lights are turned off. In this case, it may be difficult for the occupants to estimate the preparation route and a safety accident may occur in which they are trapped indoors.

In order to solve this problem, in the present invention, the fire protection function is first performed before the electricity is cut because the fire plate 330 descends as soon as the fire signal is received. For this reason, it is useful in case of an emergency if an evacuation route display unit DSP as shown in FIG. 10 is displayed on the fire panel 330 .

Such an evacuation route indicator (DSP) is provided in such a way that a photoluminescent material is applied at a position avoiding the point where the extinguishing fluid is ejected. At this time, the photoluminescent material is not a general paint, but has been specially created and formulated by the present inventors so that it can be displayed for a long time with excellent photoluminescence properties while also having fire resistance. Therefore, the present invention also provides a method for manufacturing such a photoluminescent material.

The photoluminescent material according to the present invention includes a first step of crushing a strontium mineral to a particle size of 50 mm or less, and a second step of putting the crushed mineral in the first step into a heating and drying furnace and heating and calcining at 800-1200° C. for 3 hours Step, a third step of pulverizing the reduced calcined mineral through the second step with a nano grinder, and a fourth step of sieving and selecting only the particle size of 10 nm or less from the pulverized product pulverized through the third step; The prepared phosphorescent powder is used.

At this time, the reason for crushing the strontium mineral to a particle size of 50 mm or less in the first step is to increase the effect of reducing heating and calcination. That is, it is more efficient to process small-volume objects than large-volume ones.

In addition, the heating and drying furnace used in the second step is a rotary kiln and is configured to be rotary heated and fired with strong hot air. This is to burn or volatilize impurities contained in strontium minerals, especially substances that inhibit afterglow luminance, while heating up to 1200°C, before completely dissolving in liquid phase, because strontium minerals are dissolved at 1300°C. Because.

In particular, since the hot wind is blowing, the impurity removal efficiency is very good. With respect to 100 parts by weight of the photoluminescent powder thus made, 3.5 parts by weight of waste glass powder having a particle size of 10 nm or less, 15 parts by weight of expanded graphite, 15 parts by weight of sodium hydroxide and 50 parts by weight of an epoxy resin were mixed and coated to form an evacuation route display part (DSP). ) to form

Here, the waste glass powder is to increase the afterglow luminance, and the expanded graphite, sodium hydroxide and epoxy resin increase the fire resistance.
