It is also to be understood that the position or arrangement of the individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings in order that those skilled in the art can easily carry out the present invention.

1 is a block diagram of an apparatus for detecting a breaker operation delay time according to an embodiment of the present invention.

1, an apparatus for detecting a breaker operation delay time according to an exemplary embodiment of the present invention includes at least one of a relay 110, an input unit 120, a processing unit 130, an output unit 140, and a storage unit 150 Some may be included.

A remote terminal unit (RTU) can control the breaker (CB). The remote terminal unit (RTU) may remotely receive a breaker control signal, receive it by field operation or receive it from a protection relay. For example, the remote terminal unit RTU may control the operation of the circuit breaker CB in response to the switches 20a, 20b, and 20c whose ON / OFF states are determined according to the source of the circuit breaker control signal.

The relay 110 can control the contact connected to the input terminal of the remote terminal RTU according to the current of the trip coil due to the opening and closing operation of the circuit breaker CB. Accordingly, the information at the time when the breaker CB has opened and closed can be input to the remote terminal unit (RTU), and can be reflected in the sequential event information of the remote terminal unit (RTU) described below.

For example, the relay 110 may be an auxiliary relay, the contact may be an a contact of an auxiliary relay, and the input may be a DI point of a remote terminal unit (RTU).

The input unit 120 may receive a sequence of event (SOE) information including a control procedure of a remote terminal unit (RTU). For example, the sequential event information may include a plurality of event information shown in FIGS. 4A to 4C and information on the time of the event occurrence.

The processor 130 may generate the breaker operation delay time information corresponding to the point of contact control of the relay 110 based on the sequential event information.

Since the contact point of control of the relay 110 can be used as a reference point of the event occurrence time information, the processor 130 applies the sequential event information to which the contact point-in-time information is added to the predetermined logic, Time information can be generated.

Thus, the delay time of the breaker operation can be detected quickly and accurately, and the power supply failure and the cost incidence due to the breaker abnormality can be reduced.

The processor 130 compares the breaker operation delay time with a predetermined upper limit value and a lower limit value, generates breaker delay operation information when the delay time corresponding to the breaker operation delay time information exceeds the upper limit value, The breaker normal operation information can be generated when the delay time corresponding to the breaker operation delay time information is within the range of the upper limit value and the lower limit value. Here, the predetermined upper limit value and the lower limit value may be selected according to the mode of the circuit breaker, the voltage or the current.

The output unit 140 may output at least one of the breaker operation delay time information, the breaker delay operation information, and the breaker normal operation information in real time. For example, the output unit 140 may visually and / or audibly convert the format of the breaker operation delay time information and output the converted information through an HMI (Human-Machine Interface). For example, the output unit 140 may reflect the breaker operation delay time information to the communication signal and remotely transmit the communication signal to the manager or the system.

Accordingly, the passive analysis process of the manager for the breaker operation delay can be reduced, the analysis amount of the circuit breaker delay operation for the breaker operation delay can be reduced, and the control planning efficiency of the system can be improved.

The storage unit 150 may cumulatively store the breaker operation delay time information based on a contact control point of the relay 110 as a reference unit. Accordingly, a large amount of information on the breaker operation delay can be stored systematically, and the stored information can be smoothly transmitted to the manager or the system.

2 is a diagram schematically showing control / monitoring through a remote terminal apparatus.

Referring to FIG. 2, a remote terminal unit (RTU) can receive control signals or monitoring signals from the centralized monitoring control panel 30, the field facility 40, and the digital substation 50.

The control signal transmitted from the digital substation 50 may be transmitted to the remote terminal unit (RTU) through an IED (Intelligent Electronic Device).

Meanwhile, the remote terminal unit (RTU) can be synchronized via GPS. Here, the reference time point for synchronization can be set as the contact point control point of the relay. Accordingly, the operation delay time of the circuit breaker CB can be detected more accurately.

3 is a diagram specifically illustrating control / monitoring through a remote terminal device.

Referring to FIG. 3, the centralized monitoring and control panel 30 may include a remote control system and a PITR (Protective Information Transmitter and Receiver).

The remote control system includes an HMI 51 for selecting and executing a power supply operating point, a HOST 52 for identifying the database and executing commands of the FEP 53, an FEP 53, and a first modem 54 for converting the command into a communication signal and transmitting the command. The PITR may include a second modem 55 for converting and transmitting the communication signal received from the first modem 54. [

3, the remote terminal unit RTU includes an MPU 61 having a main processing function, a CPU 62 for controlling the control card 63, a control card 63 for driving the auxiliary relay 66, , And may control the on-site facility 64 such as a breaker and generate sequential event information 65, which may include control procedures.

FIG. 4A is a graph illustrating a voltage-based breaker operation delay time when the circuit breaker is operated by a protection relay (first mode). FIG.

Fault current can occur due to breaker failure. The protection relay may perform a protection operation to the breaker according to the detection of the fault current. The time from when the fault current occurs to when the protection operation of the protection relay starts (Ry Pick Up) may be 15 ms or 33 ms.

After the protective operation of the protective relay, the breaker trip can be performed. The time from the start of the protection operation of the protection relay (Ry Pick Up) to the reference point (CB Trip) at which the breaker trip is to be performed may be 50 ms or 100 ms.

If the tripping of the breaker is delayed, the time from the start of the protection operation of the protection relay (Ry Pick Up) to the time of the breaker trip (SOE) may exceed 50 ms or 100 ms.

For example, if the breaker voltage is 345 kV or 154 kV, the breaker operation delay time may be the time minus 83 ms in SOE time.

For example, if the breaker voltage is 22.9 kV, the breaker operation delay time may be the time subtracted from the SOE time by 115 ms.

The apparatus for detecting a breaker operation delay time according to an embodiment of the present invention calculates a time obtained by subtracting a time from a time until a breaker trip is performed (SOE) to a reference time (CB Trip) The breaker operation delay time can be detected through the configured logic.

4B is a graph showing the operation delay time of each breaker according to voltage when the breaker is remotely operated (second mode).

The centralized supervisory control panel transmits a breaker (CB) control command to the PITR, and the PITR can transmit the received control command to the remote terminal device. The breaker can be opened according to the control command.

When the opening of the breaker is delayed, the time until the remote terminal device opens the breaker may exceed 50 ms or 100 ms.

For example, if the breaker voltage is 345 kV or 154 kV, the breaker operation delay time may be 55 ms in SOE time and the time minus the breaker (CB) control command time.

For example, if the breaker voltage is 22.9 kV, the breaker operation delay time may be the time taken to subtract 105 ms from the SOE time and the CB control command time.

The apparatus for detecting a breaker operation delay time according to an embodiment of the present invention calculates a time obtained by subtracting a time from a time until a breaker trip is performed (SOE) to a reference time (CB opening) The breaker operation delay time can be detected through the configured logic.

4C is a graph showing the operation delay time of each breaker according to voltage when the breaker is operated in the field (third mode).

The supervisor's CB (CB) field control input can energize the trip coil. The current by the excitation of the trip coil can open the circuit breaker CB.

When the opening of the breaker is delayed, the time until the remote terminal device opens the breaker may exceed 50 ms or 100 ms.

For example, if the voltage of the breaker is 345 kV or 154 kV, the breaker operation delay time may be 50 ms in SOE time and a time minus the breaker (CB) field control time.

For example, if the breaker voltage is 22.9kV, the breaker operation delay time may be 100ms at SOE time and the time minus the breaker (CB) field control time.

The apparatus for detecting a breaker operation delay time according to an embodiment of the present invention calculates a time obtained by subtracting a time from a time until a breaker trip is performed (SOE) to a reference time (CB opening) The breaker operation delay time can be detected through the configured logic.

Since the calculation formula of the breaker operation delay time may differ depending on the mode of the breaker or the voltage or current, the logic may be selected according to the mode of the breaker or the voltage or current.
