Description

SYSTEM AND METHOD FOR PREVENTING MIS-OPERATION OF POWER EQUIPMENT USING IMAGE CODE}

The present invention relates to a system and method for preventing a power plant misoperation using an image code, and more particularly, an image code that prevents power outage and burnout caused by a power plant misoperation during an interruption of a power plant. The present invention relates to a system and method for preventing tampering with power equipment.

Power installations installed in the power system provide the electricity generated by the power plant to the consumer (ie consumer). In other words, power facilities installed in the power generation system produce power through power generation, power facilities installed in the transmission system transmit power generated by the power generation system, and power facilities installed in the power distribution system receive power transmitted through the power transmission system. To supply.

Power systems in the power system aim to supply the generated power to consumers without interruption. To this end, maintenance on the power plant is an essential task in the power sector. In the case of the installation, extension, or maintenance of the power equipment for maintenance of the power equipment, it is necessary to stop the operation of the power equipment in use (i.e., cease-fire). The ceasefire of a power facility is a difficult process that is a sophisticated plan.

For example, Korean Patent Publication No. 10-2008-0021473 (name: system for preventing breaker misoperation using set theory and its method) provides SCADA to provide stable operation of a power system by preventing power supply interruption due to human error. When a power equipment operation command such as opening of a breaker is issued in the system, the radial system operation information is used to determine whether the breaker operation causes an interruption in power supply, and provides a technology for providing the SCADA operation personnel with related information. .

If the work is not carried out according to the planned procedure and sequence, the power supply is cut off from the power equipment other than the power equipment to be interrupted, causing a series of failures. As such, unforeseen breakdowns in power installations can lead to disruption of the power supply, resulting in enormous damage to the nation's industry and society. For example, suppose that the power supply is cut off and the truce work is performed in order to check the power facilities of substation A to B substation system. . At this time, if the operation switch of the substation A-C substation system that is not approved for the cease-fire operation is operated, the power of the substation A-C substation system is cut off, and the substation A cannot receive power from anywhere. Therefore, since substation A cannot supply power to the lower distribution lines, unexpected power outages occur in many areas of substation A. If the spread is larger, power supply to neighboring substations B and C is also unstable. It may cause a power outage.

Conventionally, the armistice operation is performed based on the 'equipment operation procedure' document which describes a procedure for operating a switch of a power facility during an armistice operation for a truce operation of a substation. That is, as shown in Figure 1 through the operation of the breaker, disconnector, grounding switch, such as the cease-fire operation and return operation of the power equipment is in progress. At this time, the cease-fire operation of the power equipment is a very difficult operation, and the cease-fire operation is not performed according to the switch operation procedure described in the equipment operation procedure, which causes a serious failure of the power equipment when the switch operation sequence is changed or the device number is changed. There is a problem.

As such, in the related art, the present invention relies solely on a method of visually confirming whether or not an operation of an apparatus to be operated by an operator during an armistice operation is approved. In other words, the worker relies on manpower as a way to check whether the operation equipment of a large number of substations can be operated in real terms by comparing them with the contents described in the equipment operation procedure.

2 is a schematic diagram of a general cease-fire operation procedure, the operator uses a wired / wireless communication with a high-level manager (for example, power exchange, feeder, feeder or distribution command room) that manages power equipment operation. Use or verbally request and verify. Here, CB (Circuit Breaker) shown in Figure 2 is a breaker, DS (Disconnecting Switch) is a disconnector, ES (Earth Switch) means a ground switch. At this time, the general ceasefire operation sequence of the substation is made in the order of CB, DS, ES, the return (that is, the recovery) is made in the reverse order of the ceasefire operation.

This can't fundamentally prevent human error due to worker's misunderstanding or misunderstanding, and it can't prevent misoperation of power equipment and cause serious failure.

Accordingly, power companies are taking various measures to prevent misoperation of electric power facilities. For example, a worker's supervisor attends during an armistice work to double-check the operation or operate a checklist to check the operation status. Here's how. However, the presence of a supervisor and the operation of a checklist require a lot of cost and time, and there is a problem in that it is inefficient and cannot completely prevent misoperation.

Nevertheless, serious failures continue to occur due to the operator's misunderstanding or misunderstanding during the ceasefire operation of electric power facilities. In the current period of cease-fire operation of power facilities, if a power failure occurs continuously and a power outage occurs, the image of the power supply company is lost, and the damages of the power company are caused by collective compensation for the power failure. There is a problem that occurs, human / material costs due to the identification, inspection, and recovery of the power failure.

At this time, the displayed screen means that the Dorim # 1T / L 23 transmission tower (or distribution tower) is a truce.

To check the status of transmission towers and distribution lines, a special high-pressure test rod and live alarms are used to perform an armistice test. However, since the test rod and live wire alarm are inconvenient to carry, expensive, and not everyone can carry, safety accidents such as an electric shock accident due to a worker's misunderstanding may occur. Thus, by photographing the image code attached to the transmission tower, it is possible to check the pressurized / cease-fire state of the transmission tower (or distribution column) to prevent the occurrence of a safety accident.

18 and 19 are power equipment information output when photographing the image code of the ground wire installed in the transmission tower. When the truce work on the transmission line is interrupted by the voltage induced by the other transmission line under pressure, the induction voltage is avoided by connecting the truce line with the transmission tower and the ground line. After the cease-fire work is completed, the ground wires installed on the transmission tower must be removed in order to recover. If the power line is installed with the ground line installed, the power line becomes grounded, causing the power line to fail. Therefore, in order to restore the truce, it is very important to ensure the integrity of the transmission line while removing all the ground lines installed on the transmission line. Previously, this verification was solely by verbal reporting by the operator. By the way, since the transmission line is a line up to 200km in case of a long transmission line, due to the error of this checking process, the truce may be restored without removing the ground line. Therefore, by applying the present invention, the image code is attached to the ground wire, and remotely control the installation and removal of the ground wire. At this time, when the image code of the ground line is taken, as shown in FIG. 18, a screen indicating that the ground line should be installed (or installed) is output, or as shown in FIG. 19, the screen indicating that the ground line should be removed is shown. Output Accordingly, there is an effect that can minimize the human error by the worker or manager.
