You configure the database separately from the scenario database, and this scenario data A database having resto_p, ann_p, fault_p, analog_p, and relay_p tables is connected to the database, respectively. According to the disclosed technology, it is possible to implement a virtual reality or an expert system similarly to recovering from the actual field, and to implementing and recovering the failure of the power system in a realistic way beyond simply acquiring the existing recovery procedure as text. By introducing a simulator, it can be a simulator more similar to a real system.

Korean Registered Patent No. 10-0543543 (registered on Jan. 9, 2006) provides an analysis and training method for any system operation in order to improve the ability of operators to deal with crisis in the event of a large power outage of the domestic transmission network. It describes the operation method of the training system to which the power system fault recovery training algorithm is developed for the development of the environment system. According to the disclosed technology, in the method of operating the training system to which the power system fault recovery training algorithm is applied, through the user graphic interface for the system diagram, the database management, the fault recovery training that the power system fault recovery training algorithm is performed Once training has commenced, if there is a power outage command on the grid for line on / off, generator output adjustment, load input and before the system operation phase, then the system will disconnect all breakers before operating the system. Trip, set the active power, reactive power, voltage, phase angle of all buses to 0, and when the system operation is completed, the training system performs the analysis module and consists of the static DB and the dynamic DB. / E Converts data to a database built with data formats SAV and CAS extensions After constructing the Y-matrix for all grids, performing tidal current calculations, determining the generator reactive power supply excess, busbar overvoltage, and line overload, and graphically communicating the results to the user through the user graphical interface. After the power system analysis is completed, the education and training system prepares for the user's system recovery operation again. At this time, if the grid connection command is given to the training system, the current power system data is stored in the CAS file, the grid connection storage format. Characterized in that it comprises a step.

The conventional simulation simulator as described above has a limit of up to three persons who can be simultaneously trained, and can train only for a single failure, and cannot train against a continuous failure during training. It was impossible to train the trainee, and it was impossible to reserve the trainee because there was no reservation function, and the accuracy was lowered by performing the faucet T / L tidal calculation by applying only the average value power according to the load. In addition, it could not process the actual equipment sound during operation, and had the disadvantage of having to perform training on the failure of transmission line, transformer, distribution line, B / F, UHF.

In the conventional simulation simulator as described above, up to three trainees can be trained on one instructor, for example, and if the number of personnel is increased because the data is unilaterally transmitted to the set IP address, the simulation failure is transmitted. There were many cases where the training could not be performed normally due to various problems such as errors and errors in real-time data transmission according to the training center recovery process.

The conventional simulation simulator as described above, for example, was unable to perform training for additional failures while the trainer was aware of and repaired the failure after the instructor initially set the failure and sent the failure to the trainer. After setting various complex faults at the time of setup, it was not possible to perform fault transmission at the same time, and also, after the fault occurred, the instructor set additional faults when real-time processing of the fault recovery data was performed by the instructor while the fault was recovered. If the additional fault is transmitted afterwards, it will collide with the recovery data of the training center, so it is impossible to set the additional fault itself because there are many problems such as data loss or an error.

In the conventional simulation failure simulator as described above, the 154kV model power supply T / T is implemented by, for example, treating the power supply source in the substation through a 154kV model power supply T / L (transmission line) to secure the power supply. When the power supply of L was interrupted, the simulation of the substation system was different from the reality. In addition, if all of the substations are outage, select one of the D / L (distribution line) in advance to secure the on-site power and operate as on-site D / L to normalize the substation by receiving power back through the on-site D / L. However, the tide calculation algorithm to secure the on-site power supply through the 154kV model faucet T / L has no algorithm to secure the on-site power supply by receiving the D / L inverse, so that normal simulation failure could not be trained.

The conventional simulation simulator as described above can only train for example transmission line side faults, transformer internal faults, distribution line side faults, breaker breaker B / F (Breaker Fail) faults, and UFR faults. Training was not possible due to various failures that existed, and there was a limit in improving the recovery capability of substation workers.

Trainer terminals 200-1 to 200-N are PCs (or laptops or miniature machs equipped with PCs) used by the training institute, and are equipped with training software (ie, training program). In accordance with the operation (ie, execution) of the program for training personnel, simulation simulation, training accident recognition and recovery operation are performed, for example, login of the training staff, display of the power system selection screen, transmission of the power system screen request signal, Display of power system screen, display of various simulation failure conditions, display of recovery operation result information, etc.

Can be expressed. For example, the training terminals 200-1 to 200 -N may express various simulation failures that may occur in the 154kV model substation in response to the confirmed simulation failure information.

In one embodiment, the training terminal (200-1 ~ 200-N), can be expressed about the accidents that can occur in the 154kV model substation as a simulated failure that can be expressed, the accident expression details (that is, the production details ), A fault on the transmission line (T / L), which is a machining or underground line that connects the substation and the substation, and a fault on the bus side provided by two buses (ie, the first bus and the second bus), Up to four transformers are usually installed in the substation, and it is responsible for reducing the 154kV voltage to 22.9kV voltage, but depending on the situation, the transformer (M.Tr) side fault, which can be boosted and operated in reverse, is usually used in one substation. Up to 4 transformers are installed, each section is divided into transformers to share the load by transformers, and up to 8 distribution lines can be installed in one transformer to handle the load of transformers. And emo Is divided into eight by bus section, the first bus side is divided into 40BUS, 41BUS, 42BUS, 43BUS, and the second bus side is divided into 45kV, 46BUS, 47BUS, 48BUS. I can express it.

First, transmission line (T / L) failures include short circuit, ground fault, transmission line GIS or DS failure, and transmission line B / F (Breaker Fail) failure.

In case of short circuit or ground fault (i.e., short circuit or ground fault in the transmission line section), the train terminal (200-1 to 200-N) can display the short circuit and ground fault set by the instructor. Therefore, it is a drive to operate the main protection or rear protection relay in response to the correct recovery operation of the training center, and can immediately protect the facility by blocking the corresponding breaker to prevent accident current from flowing to other facilities through the transmission line. .

In case of transmission line GIS or DS failure (i.e., failure due to breakdown of insulation inside the transmission line equipment), the training terminal 200-1 to 200-N is connected to the transmission line GIS set by the instructor. It can express DS failure, and in response to the trainee's exact recovery operation, it operates the bus protection relay in response to it, and protects the equipment by blocking all transmission line or transformer primary side breaker connected to the accident bus. Can be.

In case of transmission line B / F failure (i.e. when the line breaker is inoperable, if a short circuit, ground fault and B / F failure occur at the same time in the line, When the circuit breaker is not cut off by the non-operation), the trainer terminal 200-1 to 200-N can display the transmission line B / F failure set by the instructor, and thus the correct recovery of the trainer In response to this operation, the bus protection relay of the bus line connected to the transmission line can be operated accordingly, and all of the other transmission line or transformer primary side breakers connected to the bus line can be cut off in a batch to protect the facility. In this case, the transmission line breaker may maintain the input state by the non-operation.

Second, the bus side faults include a first bus failure and a second bus failure.

In the case of the first bus failure (i.e., the insulation of the first bus is broken and the transmission line and transformer connected to the first bus cannot receive power through the first bus), the training terminal 200- 1 ~ 200-N), the instructor can express the first bus failure, and according to the correct recovery operation of the trainee to operate the bus protection relay in response to this, the transmission line connected to the first bus And the transformer primary circuit breaker can be tripped.

In the event of a second bus failure (i.e. when the insulation of the second bus is broken and the transmission line and transformer connected to the second bus cannot receive power through the second bus), the training terminal 200- 1 ~ 200-N), the instructor can express the second bus failure, and in response to the correct recovery operation of the trainee to operate the bus protection relay in response to this, the transmission line connected to the second bus And the transformer primary circuit breaker can be tripped.

Third, the transformer (M.Tr) side fault is: transformer internal fault, transformer primary side GIS or DS fault, transformer secondary side GIS or DS short circuit fault, transformer secondary side GIS or DS ground fault, transformer secondary side GIS or DS ground fault And NGR disconnection failure.

In the case of a transformer internal failure (i.e., when a transformer internal failure (mechanical failure, electrical failure) occurs), the trainer terminal 200-1 to 200-N will display the transformer internal failure set by the instructor. In response to this, the driving of tripping the transformer primary and secondary circuit breakers can be prevented according to the correct recovery operation of the training center, thereby preventing the spread of failure to other facilities.

In case of transformer primary GIS or DS failure (i.e., failure due to transformer primary GIS or DS insulation breakdown), the trainer terminal 200-1 to 200-N is the transformer 1 set by the instructor. It can display the GIS or DS failure of the vehicle side, and in response to the exact recovery operation of the trainee, it operates the bus protection relay in response to it, and blocks the transmission line connected to the accident bus or the primary circuit breaker of the transformer. It can protect you.

In the case of a transformer secondary GIS or DS short circuit failure (i.e., a failure due to transformer secondary GIS or DS insulation breakdown), the trainer terminal 200-1 to 200-N is a transformer set by the instructor. Secondary side GIS or DS short circuit fault can be displayed and the 51S relay is operated according to the trainee's exact recovery operation, and the transformer secondary side breaker is connected to the 23kV BUS side connected to the accident transformer. You can block all of them.

In the case of a transformer secondary GIS or DS ground fault (i.e., a failure due to transformer secondary GIS or DS insulation breakdown), the trainer terminal 200-1 to 200-N is a transformer set by the instructor. Secondary GIS or DS ground fault can be displayed and the 51SN relay is operated in response to the trainee's correct recovery operation.The fault is propagated to the 23kV bus connected to the accident transformer. All car breakers can be blocked at once.

In case of transformer secondary GIS or DS ground fault and NGR disconnection failure (i.e. when transformer secondary GIS or DS insulation breakdown failure and NGR breakdown failure occur simultaneously, the transformer cannot detect ground fault due to NGR disconnection) For example, the trainer terminal 200-1 to 200-N can express the transformer secondary GIS or DS ground fault and NGR disconnection fault set by the instructor, and according to the correct recovery operation of the instructor, the corresponding 59GT If the fault transformer is connected to the health bank after tripping the transformer primary and secondary circuit breakers, the ground fault element is spread and the primary and secondary circuit breakers can be tripped by the 51SN relay.

Fourth, 23kV distribution line (D / L) side faults include distribution line short circuit, ground fault, distribution line GIS or DS short circuit failure, distribution line GIS or DS ground fault, distribution line GIS or DS ground fault and NGR disconnection fault. .

In the event of a short circuit or ground fault in the power distribution line (that is, when a short circuit or ground fault occurs in the power distribution line), the trainer terminal 200-1 to 200-N detects a short circuit fault or ground fault set by the instructor. In response to the correct recovery operation of the training center, the overcurrent and overvoltage relays can be operated accordingly, and the corresponding circuit breakers can be tripped to protect the distribution lines.

In the case of a distribution line GIS or DS short circuit failure (i.e., a failure occurs due to a distribution line GIS or DS insulation breakdown), the trainer terminal 200-1 to 200-N is a distribution line GIS set by an instructor. Alternatively, the DS short circuit fault can be expressed, and the 51S relay is operated according to the trainee's exact recovery operation.A fault is spread to the transformer side connected to the corresponding bus and the transformer secondary circuit breaker is shut off. Can give

In the case of a distribution line GIS or DS ground fault (i.e., a failure occurs due to a distribution line GIS or DS insulation breakdown), the training terminal 200-1 to 200-N is a distribution line GIS set by an instructor.

When the D / L designated as on-site D / L is pressurized, the corresponding 23kV model bus is pressurized, and the D / L, which can be powered through the pressurized bus, is pressurized at the same time to supply power to other distribution preferences. have. If the secondary breaker and breaker are inserted, the primary transformer is boosted through the secondary transformer to pressurize the connected 154 kV model bus, and if the load is generated through the pressurized 154 kV model bus after the pressurization, In the case of abnormality, the counterpart of in-house D / L may trip and cut off power supply.

In case of side fault, the corresponding distribution preference circuit breaker should be tripped, but it means that the short circuit 51S and the ground fault 51SN element detection relay are operated by the delay trip, so that the peripheral voltage transformers 1 and 2 are tripped only once.

In case of breaker internal breakdown, the fault of the breaker inside the breaker inside the 23kV model distribution line tripped and the breaker of the main transformer 1 and 2, and the breaker inside breaker of the 154kV side breaker line (T / L). The protection relay operates to trip all connected circuit breakers, the fault of the main transformer primary circuit breaker tripped by the fault inside the secondary transformer breaker, and the bus protection relay connected to the bus side connected by the internal fault of the main transformer primary breaker. A fault that trips all connected breakers.
