Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power consumption monitoring system and a method thereof,

The present invention relates to a system and method for real-time use of a power consumer for monitoring electric power consumption for electric power saving.

In general, electric energy consumption in Korea has been steadily increasing since the 1970s due to the improvement of living standards, the pursuit of convenience and the intermediate energy production - oriented energy rather than the non - industrial structure.

The price of electricity, which is the primary energy, continues to rise and the cost of electricity increases. However, electricity prices, which are secondary energy produced by processing the electricity, have only recently risen, but the government is relatively free from gas or oil Has continued.

On the other hand, the imbalance in the relative price of energy caused by electricity prices that do not reflect actual energy prices is giving a distorted signal to each economic entity 's consumption and investment, causing side effects.

For example, in the domestic manufacturing industry, overcapacity investment is taking place mainly in the energy consuming industry due to the relative low price of electricity. In addition, the use of electric heating and cooling in general buildings is increasing rapidly. Recently, the demand for energy conversion, in which the heating of building, which was using gas or oil, is gradually replaced by electricity is also increasing rapidly.

As a result, there is a vicious cycle in which electric power demand must be renewed every year and the power plant must be built continuously. However, it is very difficult to build a large capacity power plant due to domestic and foreign incidents such as the anxiety of the people and the parts irregularity about the nuclear power plant after the recent incident in Japan.

The bigger problem is that as the power system grows, the construction of transmission lines and substations, which are essential for the transmission of electricity, is suffering from environmental problems and local civil complaints.

Therefore, in recent years, it is difficult to cope with an increase in electric power demand due to the expansion of the electric power supply side. Thus, there is an approach to solve the electric power supply and demand problem by regulating electric power demand. As a result, electric power demand management is becoming an increasingly important solution.

On the other hand, in such power demand management, the base charge is calculated by using the maximum demanded power of the electric power consumer, and the electric charge is calculated based on the calculated base charge.

However, at present, in this power demand management, the maximum demanded power amount of the power demanding place can not be predicted, so that the amount of used power amount of the power demanding place exceeds the maximum demanded power amount every month. This means that the electricity bill will increase due to the increase in the base rate.

Therefore, there is a need to develop a system and method for reducing electricity bills that can further reduce the base rate by effectively reducing the base rate.

(Equation 1)

Electricity charge = Basic charge + Electricity consumption charge rate + Other charge

(Equation 2)

Here, the reference power factor may be about 90%, but is not limited thereto and can be changed.

In one example, the power factor rate is calculated by multiplying the base rate of the power consumer 10 and the power consumption rate (power consumption rate) of the power consumer 10 when the power factor of the loads R ₁ to R _N provided to the power consumer 10 exceeds the pre- ≪ / RTI > Accordingly, the current monthly electricity charge of the power consumer 10 can be reduced by the power factor rate.

In another example, the power factor rate may be calculated by multiplying the base rate of the power consumer 10 and the power consumption rate (e.g., power consumption rate) of the power consumer 10 when the power factor of the loads R ₁ to R _N provided in the power consumer 10 is less than the pre- As shown in FIG. Accordingly, the current monthly electricity charge of the power consumer 10 can be added by the power factor rate.

On the other hand, the above-mentioned value-added tax and power industry-based fund among other charges may be a charge determined by law. At present, the VAT rate is about 10%, and the electric power industry based fund is 37% of the total of the base rate and the electricity usage rate, but the VAT rate and the electric power industry based fund can be changed by law.
