Abstract

Disclosed embodiments relate to a power monitoring system. In some embodiments, the power monitoring system includes: a sampling device configured to measure patterns of energy consumed by loads included in the power system; an electric meter configured to measure an amount of second energy supplied from a system to the power system; a power supply configured to supply power stored therein or generate power to supply the power system and measure an amount of third energy supplied; and an external server configured to receive at least one of the patterns, the amount of the second energy and the amount of the third energy and analyze the patterns to acquire an amount of first energy for each of the loads. In some embodiments, the external server calculates at least one of the amount of the first, second and third energy.

First claim

What is claimed is:

1. A power monitoring system comprising:
a sampling device configured to measure patterns of energy consumed by loads included in the power monitoring system;
an electric meter configured to measure a first amount of energy supplied from a transmission system to the power monitoring system;
a power supply configured to supply power stored therein or generate power to supply it to the power monitoring system; and
an external server configured to receive the patterns and obtain a third amount of energy for all the loads by analyzing the patterns,
wherein the external server is further configured to:
receive one of the first amount of energy and a second amount of energy, wherein the second amount of energy is an amount of energy supplied from the power supply; and
calculate any one of the first amount of energy and the second amount of energy that is not received by the external server,

wherein if the first amount of energy is not received by the external server, the external server is configured to subtract the third amount of energy from the second amount of energy to calculate the first amount of energy,
wherein if the calculated first amount of energy is a positive value, it is determined that the second amount of energy supplied from the power supply is larger than the third amount of energy consumed by the loads,
wherein if the calculated first amount of energy is a negative value, it is determined that the second amount of energy supplied from the power supply is smaller than the third amount of energy consumed by the loads.

2. The power monitoring system of claim 1 , wherein the external server is further configured to subtract the third amount of energy from the first amount of energy to obtain the second amount of energy when the second amount of energy is not received.

3. The power monitoring system of claim 1 , wherein the sampling device is further configured to receive the first amount of energy and the second amount of energy, and transmit the first amount of energy and the second amount of energy to the external server together with the patterns.

4. The power monitoring system of claim 1 , wherein the power supply comprises at least one of an energy management system and a power generator.

5. A power monitoring system comprising:
a sampling device configured to measure patterns of energy consumed by loads included in the power monitoring system;
an electric meter configured to measure a first amount of energy supplied from a transmission system to the power monitoring system;
a power supply configured to supply power stored therein or generate power to supply it to the power monitoring system;
a first external server configured to receive the patterns from the sampling device and analyze the patterns to obtain a third amount of energy consumed by all the loads; and
a second external server configured to receive at least one of the first amount of energy and a second amount of energy and transmit/receive data to/from the first external server, wherein the second amount of energy is an amount of energy supplied from the power supply,
wherein the second external server is further configured to receive the third amount of energy from the first external server and calculate the first amount of energy or the second amount of energy that is not received by the second external server,
wherein if the first amount of energy is not received by the second external server, the second external server is configured to subtract the third amount of energy from the second amount of energy to calculate the first amount of energy,
wherein if the calculated first amount of energy is a positive value, it is determined that the second amount of energy supplied from the power supply is larger than the third amount of energy consumed by the loads,
wherein if the calculated first amount of energy is a negative value, it is determined that the second amount of energy supplied from the power supply is smaller than the third amount of energy consumed by the loads.

6. The power monitoring system of claim 5 , wherein the second external server is further configured to subtract the third amount of energy from the first amount of energy to obtain the second amount of energy when the second amount of energy is not received.

7. The power monitoring system of claim 5 , wherein the second external server is further configured to receive at least one of the first amount of energy and the second amount of energy, and convert at least one of the first amount of energy and the second amount of energy in the form of an analog signal into digital signal to transmit to the first external server.

8. The power monitoring system of claim 5 , wherein the power supply comprises at least one of an energy management system and a power generator.

9. The power monitoring system of claim 5 , wherein the first external server is further configured to analyze the patterns acquired from the sampling device to determine the first, second, and third amount of energy of the loads.

10. The power monitoring system of claim 9 , wherein the first external server is further configured to create data based on statistical data and provide the created data to a user upon request.

11. The power monitoring system of claim 5 , wherein the first external server is further configured to accumulate the acquired third amount of energy to store as statistical data.
