Therefore, definitions of these terms should be made based on the content throughout this specification.

Figure 1 is a block diagram for explaining a supply power monitoring system according to an embodiment of the present invention, Figure 2 is a block diagram for explaining a smart meter of the supply power monitoring system according to an embodiment of the present invention .

Referring to FIG. 1 , the power supply monitoring system according to an embodiment of the present invention may include a smart meter 100 , an MCCB server 200 , a circuit breaker 300 for wiring, and a terminal device 400 .

The smart meter 100 may generate a first notification event and transmit it to the MCCB server 200 when less-than-standard power is supplied from the distribution system 10 .

The smart meter 100 is an electronic watt-hour meter based on AMI (Advanced Metering Infrastructure), is connected to the distribution system 10, measures the voltage and current flowing in the distribution system 10, and based on the measured voltage and current It is possible to determine the state of the power supplied to the house.

For example, the smart meter 100 includes WLAN (Wireless LAN), Wi-Fi (Wireless Fidelity), Wi-Fi (Wireless Fidelity) Direct, DLNA (Digital Living Network Alliance), WiBro (Wireless Broadband), LTE ( It is connected to a communication network such as Long Term Evolution), so that the measurement and determination result can be transmitted to the AMI server 500 or the MCCB server 200 connected to the communication network.

Referring to FIG. 2 , a smart meter according to an embodiment of the present invention may include a detection unit 110 , a determination unit 120 , and a control unit 130 .

The detection unit 110 may detect a voltage and a current from the distribution system 10 .

For example, the detector 110 measures the current supplied from the distribution system 10 to the house using a current transformer (CT), and uses a potential transformer (PT) to the distribution system The voltage supplied to the house from (10) can be measured. However, the present embodiment is not limited thereto, and various methods capable of measuring current and voltage from the distribution system 10 may be employed.

The determination unit 120 may determine whether power below the reference level is being supplied based on the voltage and current detected by the detection unit 110 .

According to an embodiment of the present invention, when the voltage and current detected by the detection unit 110 correspond to at least one of phase loss, undervoltage, overvoltage, undercurrent, and overcurrent, the determination unit 120 receives a reference from the distribution system 10 . It can be determined that insufficient power is being supplied.

For example, if the voltage detected by the detection unit 110 is less than or equal to the preset first reference voltage, the state of the power supplied from the distribution system 10 corresponds to a low voltage, so it can be determined that the power below the standard is being supplied. And, when the voltage detected by the detector 110 is equal to or greater than the preset second reference voltage, the state of the power supplied from the distribution system 10 corresponds to an overvoltage, so it can be determined that the power below the reference is being supplied.

For example, if the current detected through the detection unit 110 is less than or equal to the preset first reference current, the state of the power supplied from the distribution system 10 corresponds to the low current, so it is determined that the power below the standard is being supplied. If the current detected through the detection unit 110 is equal to or greater than the preset second reference current, the state of the power supplied from the distribution system 10 corresponds to overcurrent, so it can be determined that less than the standard power is being supplied. .

A phase loss may be caused by a short circuit, disconnection, or ground fault of an electric wire, and it means a state in which one or more phases of the polyphase power supply are faulty. A short circuit, disconnection or ground fault may be caused by repair work, a failure of the grid power itself or line failure, or the operation of a circuit breaker to protect the grid power.

The detection unit 110 may measure the three-phase current and the three-phase voltage of the distribution system 10 , and the determination unit 120 determines the three-phase current and the three-phase current of the distribution system 10 measured through the detection unit 110 . When the current or voltage in one or more phases of the voltage changes abruptly, or when a difference occurs with the current or voltage in a normal state where no phase loss occurs, the state of power supplied from the distribution system 10 corresponds to a phase loss and is below the standard. It can be determined that power is being supplied.

When it is determined through the determination unit 120 that power below the standard is being supplied from the distribution system 10 through the determination unit 120 , the control unit 130 may generate a first notification event and transmit it to the MCCB server 200 .

The first notification event includes information for notifying the MCCB server 200 that the power below the standard is being supplied from the distribution system 10 .

According to an embodiment of the present invention, the first notification event and the second notification event to be described later are measured through the detection unit 110 and whether a phase loss occurs, whether a low voltage occurs, whether an overvoltage occurs, whether a low current occurs, and whether an overcurrent occurs. It may include the voltage and current to be changed, and whether or not to recover.

Power recovery means that the power distribution system 10 is restored to a normal state again after a phase loss, low voltage, over voltage, low current and over current are generated from the power distribution system 10, and whether power is restored is determined by the first notification event and the second notification event. By including it, it is possible to provide information for determining whether the user cuts off the distribution system 10 using the circuit breaker 300 for wiring.

For example, when it is determined that substandard power is being supplied from the distribution system 10 through the determination unit 120 , the control unit 130 determines whether phase loss, undervoltage, overvoltage, undercurrent and overcurrent occur, and the detection unit By generating a first notification event including the voltage and current measured through 110 and whether or not power is restored, the smart meter 100 and the MCCB server 200 are connected to the MCCB server 200 through the connected communication network.
