In the present invention, power consumption information and temperature information transmission of each customer 100 may be performed in real time or for a predetermined time period.

Referring to the operation of the system of the present invention configured as described above are as follows.

First, the power generation system 500 generates a predetermined amount based on the power demand prediction value of the power management device 400. The electric power generated in this way is transformed into consumer power through the substation system 600 and then supplied to the consumer 100 as load power.

The power supplied to each customer 100 is consumed according to the power demand of the customer, and the consumption is sensed and accumulated by the power meter reading sensor (not shown) and stored in the memory unit 220 of the data intensive device. It is transmitted to the management device 400 or to the power management device 400 through the mobile communication network through the mobile communication terminal.

The power management device 400 receives power consumption information and temperature information from the data concentrator 200 and calculates a discount rate / surcharge rate according to the temperature transmitted from the power consumer according to a predetermined discount rate / surcharge rate calculation method for each temperature. The calculated discount rate / surcharge rate is applied to the power consumption to settle and collect the total power bill.

As shown in the figure, the data concentrator 200 of the present invention includes a control unit 210, a memory unit 220, a program memory unit 230, and a display unit 240.

The memory unit 220 includes information on the power consumer, such as the temperature sensor output signal (temperature information) and the meter output signal (power usage information) received from each customer 100, as well as each customer ID transmitted with this information. It is stored.

 The memory 220 may also include discount / extra information according to the building temperature.

When there is a request for the information from the control unit, the information stored in the memory unit 220 is retrieved and transmitted to the power management apparatus through a transceiver (not shown).

3 is a block diagram illustrating the power management apparatus 400 of FIG. 1 in more detail.

As shown in the figure, the power management device 400 of the present invention comprises an aggregation unit 410, the central control unit 420, the customer DB 430 and the power bill collector 440.

The aggregation unit 410 aggregates power consumption information and temperature information of each power receiver by the data concentrator or the mobile communication terminal for each customer ID.

The customer DB 430 stores power consumption information and temperature information aggregated by the aggregation unit 410 for each customer ID. In addition, the customer DB 430 stores power usage information and set contract amount information for each power customer.

In addition, the customer DB 430 includes a method of calculating a discount rate / percentage for each temperature for calculating a discount rate / surcharge rate according to the temperature transmitted from the power customer (see FIG. 4).

The power charge collector 440 reads the power consumption information and temperature information, calculates a discount rate / surcharge rate according to the temperature in the building, applies the discount rate / surcharge rate to the power consumption, and then bills and collects the total power charge. The discount rate / percentage calculation may be performed by the central controller 420 according to the temperature in the building.

In addition, the power bill collector 440 determines a premium rate / discount rate calculation method according to the upper / lower temperature limits of the summer / winter season in advance and calculates the total power rate according to the premium rate / discount rate calculation method when the corresponding information is transmitted.

The central control unit 420 is connected to the counting unit 410, the customer DB 430 and the power bill collector 440, and controls them. That is, the central control unit 420 controls to store the power consumption information and temperature information aggregated by the aggregation unit 410 in the customer DB 430, and to allow the power bill collection unit 440 to settle and collect the electricity fee. The power consumption information and temperature information is retrieved from the customer DB 430 and transferred.

In addition, the central control unit 420 controls the devices in the power management device 400 to transmit the information request signal to the control unit 210 of the data intensive device at a certain time or at the request of the power personnel.

In addition, the central control unit 420 has a structure for operating and managing the power generation system 500 with the power reserve ratio setting information, the power generated by the power generation system 500 is transformed into each customer power through the substation system 600. And supplied to each customer (load) 100 side.

4 is a graph showing a temperature in a winter building according to an example of the present invention.

As described above, the power bill collector 440 reads power consumption information and temperature information for each customer ID stored in the customer DB 430, and calculates the electric power customer ( Calculate the discount rate / extra rate according to the temperature transmitted from 100). In addition, the calculated discount rate / surcharge rate is applied to the power usage to settle and collect the total power rate.

This discount rate / premium rate calculation method will be described with reference to the graph of FIG.

4 is an example of measuring the temperature in a building in which many office workers in winter.

Referring to the drawing, the temperature inside the building began to rise little by little at 9:00 am when workers went to work to turn on heaters such as heaters and computers, and the heaters were turned off during lunch (12:00 to 1:00). As it was (OFF), it went down a bit and rose again during the afternoon working hours. Then, at 18:00, the temperature in the building dropped again. Of course, these data were measured by the heater and heat from the human body in order to exclude the environmental impact.

In addition, in the power management device 400, the upper limit temperature for the building was set to 20 degrees, and the premium application period was set from 9 am to 8 pm.

Accordingly, a surcharge is charged between 9 am to 12 am and 13 pm to 20 pm, which is a section exceeding the upper limit temperature (20 degrees), and noon (12 degrees) is a section not exceeding the upper limit temperature (20 degrees). The discounted rate will be charged between the time and 13:00.

The discount rate / premium rate is preferably applied differently according to the temperature difference (discount rate / extra rate). For example, in the graph of FIG. 4, a premium is applied from 13:00 to 20:00, and a premium of 0% is charged at 13:00 and 20:00 according to the temperature range, and a 2% premium is charged from 13:00 to 14:00. A premium of 3% is applied from 14:00 to 15:00, and a 5% premium from 15:00 to 16:00, the highest value in the graph.

Here, the total power rate is the sum of the power consumptions applied by the premium rate for each section to the power consumption measured by the meter. Of course, the discount rate interval is made through the same ratio calculation as above.

The discount and premium ratio according to the temperature difference is preferably made in agreement with the building owner in advance. For example, in winter, the upper limit temperature is based on 20 degrees, and the premium rate is increased by 1% whenever the reference temperature (upper limit temperature) is exceeded by 1 degree. In other words, if the temperature inside the building is 21 degrees, 1% of the power consumption generated during that time period is premium. If the temperature inside the building is 22 degrees, 2% of the power consumption generated during that time period is premium. In the case of provinces, 3% of the electricity consumed during that time period is surcharged.

In addition, in the present invention, the building owner may operate an air conditioner, etc. to lower the building temperature, so the discount and the premium ratio should be applied to the power consumption.

In addition, the present invention may further impose a discount and a premium ratio according to the time interval. That is, even if they have the same temperature range, they must be applied differently according to time.

For example, if the premium time zone is from 9 am to 8 pm (20 pm), as shown in FIG. 4, 9 am and 8 pm of the premium time band are strictly equivalent to the same temperature (eg, 20 degrees). The utility of power reserves by time is different. In other words, even when the same power is used, the power reserve ratio may be different from the power supply provider in the case of using the power in the peak time and in the quiet time.

Accordingly, the present invention applies differently the cost (rate) imposed on the case of using the power in the peak time zone and the case of using the power in the quiet time zone.

As the premiums and discounts are applied according to the temperature in the building, the electric power receiving party (building owner, etc.) will make every effort to reduce the temperature in the building (for example, to create a plant environment). Consideration will be given to construction.

5 is a flowchart illustrating a method of charging power differential according to temperature in a building according to a first embodiment of the present invention.

1 to 5, first, the power generation system 500 generates a predetermined amount based on a power demand prediction value of the power management device 400. The electric power generated in this way is transformed into consumer power via the substation system 600 and then supplied to the consumer 100 as load power.

The power supplied to each consumer side is consumed according to the consumer's power demand, and the consumption amount (power consumption) is sensed and accumulated by the electricity meter reading sensor (not shown).

Further, temperature information is obtained from a temperature sensor installed on the power receiving side. Here, the temperature information may be obtained through a fire sensor temperature sensor installed for the fire fighting equipment.

The temperature information and power consumption information are stored in the memory unit 220 of the data intensive device (S12), and the information is transmitted to the power management device 400 at a point in time determined by a program mounted in the data concentrator 200. Or when there is a remote transmission request signal from the central control unit 420 of the power management device. (S13) (S14).

The information transmission is performed through data transmission means, which include wired data transmission means (eg, power line communication (PLC), optical cable, etc.) and wireless data transmission means (RF communication, etc.).

Of course, the present invention may use a mobile communication terminal instead of a data intensive device. That is, the power consumption information and temperature information of the power receiver side may be temporarily stored in the mobile communication terminal provided at each power receiver side, and may be transmitted to the remote power management apparatus 400 through the mobile communication network.

When information (temperature information, etc.) are transmitted to the power management device 400, customer information including each customer ID is also transmitted.

As described above, power consumption information and temperature information of the power receiver side is transmitted from the data intensive device to the power management device through the wired / wireless transmission means or when the transmission is made to the power management device through the mobile communication network using the mobile communication terminal. The aggregation unit of the apparatus classifies such information by customer ID, and the classified information is stored in the customer DB 430 under the control of the central controller 420. (S15)

Then, the power consumption information and temperature information for each customer ID stored in the customer DB are transferred to the power bill collector 440 under the control of the central controller 420 (S16), and the power bill collector 440 has already set the temperature. According to the calculation method of the discount rate / surcharge rate by each calculation method calculates the discount rate / surcharge rate according to the temperature transmitted from the power customer (S17), the calculated discount rate / surcharge rate is applied to the power consumption to claim and collect the total power bill. S18) Of course, the reference temperature (upper limit temperature, lower limit temperature), discount rate / premium rate may vary depending on the place or season.

For example, if the power usage amount transmitted from the power customer 100 is a, and corresponds to a 5% premium, the power customer should pay a power fee corresponding to 1.05 times (= 1.05a) of the power consumption.

These power rates are delivered to each customer, and the discount / additional rate information to which the discount rate / surcharge rate is applied is also transmitted so that each electric power customer can take further action.

In the present invention, a discount rate / surcharge rate may be further applied.

In addition, in the present invention, if it is determined that the power consumption of the customer on the power supply exceeds a certain level, the maximum demand power (PEAR DEMAND) of the customer may be directly controlled by using the maximum power management device.

DEMAND CONTROLLER is a device that directly controls the maximum demand power (PEAR DEMAND) of the customer by connecting with the trading meter of the power company, the operation principle is as follows. In other words, first set the target peak power of the consumer, then predict the power demand after the 15-minute demand time limit by increasing the current power, and cut off the load of several circuits within the range that the predicted value does not exceed the target power. It adjusts the used power to below the target power, and there is a microprocessor inside to monitor the power load condition all the time, and if the load is likely to exceed the preset target power within 15 minutes of the demand time, an alarm is generated. At the same time, the maximum demand power is suppressed by blocking up to eight devices sequentially from unnecessary loads, and when the load drops, the load is sequentially input by a program input in advance.

In this way, when the maximum power management device is used to perform the demand (DEMAND) control, detailed load adjustment is automatically performed by setting the target power, which is a certain upper limit value, so that the power can be effectively used within the range of the target power. It can lead to an increase in load ratio and an increase in the utilization rate of the facility, a productivity increase due to a significant reduction in the unit of production, and the utility company can reduce the investment in power generation facilities due to peak suppression.

As mentioned earlier, there will be general households that use low power, and buildings that use large power (including factories). In the case of using low power, a transformer is usually used, and in the case of using a large power, a water substation provided separately is used.

6 is an external view of a water substation apparatus according to an example of the present invention.

The high voltage power from the substation is delivered to each customer's water substation through a distribution system consisting of overhead distribution lines and underground distribution lines, and the high voltage power supplied to the customer is stepped down to a commercial voltage through the water substation and supplied to the customer.

At this time, there are a number of methods of receiving power using a high-voltage consumer power distribution device, such as a cubicle type using a panel, a frame type for receiving power by installing a frame, and an H-type faucet power receiving method using electric poles. A cubic type extra high voltage water transformer will be described with reference to FIG. 6 as follows.

The water substation is a power switchboard (A ') for receiving a high voltage and a special high voltage supplied from a substation, and the first and second substations for supplying electric devices and lights to each part by stepping down the high voltage received from the substation to a commercial voltage. (B ', C').

The switchboard (A ') has an inlet receiving power from the distribution line, an automatic section breaker installed on the load disconnection line sending power supplied through the inlet, and protects the load disconnection line when an abnormal voltage occurs in the load disconnection line. In order to protect the downstream equipment at the time of overcurrent, a lightning arrester is installed, and an integrated wattmeter is connected to a transformer transformer for measuring power supply.

In addition, the transformer current transformer for the power supply and demand meter is installed in the first and second substations B 'and C' and is connected to a transformer for stepping down the received high voltage to a commercial voltage required by the user, respectively. In the substations (B ', C'), it is connected to the substation power fuse installed on the primary side of the transformer to protect the transformer, and the parking terminal and the parking terminal, which are installed on the secondary side of the transformer and cut off the commercial voltage if necessary. It consists of multiple wiring breakers that cut off each load if necessary.

Referring to the drawings, first, the power generation system 500 generates a predetermined amount based on the power demand prediction value of the power management device 400. The electric power generated in this way is transformed into consumer power through a transformer, and then supplied to the respective consumers (corresponding to the home) 100 as load power.

Power consumption information and temperature information are obtained from a digital meter and a temperature sensor installed in each home, and this information is stored in a memory unit of the data concentrator (S22).

Thereafter, the power consumption information and the temperature information are transmitted to a remote meter reading server (AMR) via a front end processor (FEP) serving as a router through data transmission means.

The information is transmitted to the power management device at a point in time determined by a program mounted in the data concentrator 200 or when there is a remote transmission request signal from the central control unit of the power management device.

Then, the remote meter reading server classifies the power consumption information and temperature information for each household (consumer) transmitted by the corresponding customer ID and stores them in the customer database (S24).

Then, the power consumption information and temperature information stored in the customer DB by the central controller is transmitted to the power bill collector (performs the same role as the power bill collector of FIG. 1).

Then, the power bill collector calculates the discount rate / surcharge rate according to the temperature transmitted from the power consumer according to the already set discount rate / surcharge rate for each temperature.

Then, the calculated discount rate / surcharge rate is applied to the power consumption to settle and collect the total power bill. (S27)

8 is a flowchart illustrating a method of charging power differential according to temperature in a building according to a third embodiment of the present invention.

Referring to the drawings, first, the power generation system 500 generates a predetermined amount based on the power demand prediction value of the power management device 400. Electric power generated in this way is transferred to a water substation installed in a high-rise building. In this water substation, high-voltage power is received and stepped down to a used voltage and supplied by building unit or factory unit. (S31)

Power consumption information and temperature information are obtained from the digital meter and temperature sensor installed in each building (or factory), and this information is stored in the memory unit of the data concentrator.

Then, the power consumption information and the temperature information are transmitted to the remote meter reading server (AMR) via the front end processor (FEP) through the data transmission means (S33).

Then, the remote meter reading server classifies power consumption information and temperature information for each customer (building and factory) transmitted by the corresponding customer ID and stores the information in the customer DB (S34).

Then, the power consumption information and temperature information stored in the customer DB by the central controller is transmitted to the power bill collector (S35).

Then, the power bill collector calculates the discount rate / surcharge rate according to the temperature transmitted from the power consumer according to the already set discount rate / surcharge rate for each temperature.

Thereafter, the calculated discount rate / surcharge rate is applied to the power consumption to settle and collect the total power rate.

On the other hand, in the present invention, the power receiver side may enter into a maximum power use contract with the power provider side, and based on this, it may be to apply a progressive surcharge for power use in a specific time period. This allows the consumer to suppress the use of power at a certain time as much as possible.

As the premiums and discounts are applied according to the temperature in the building, the power customer side (building owner, etc.) will make every effort to lower the temperature in the building (eg plant cultivation). Will be installed.

As described above, in the present invention, a method of imposing a surcharge on an electric charge (electric charge) is used when the temperature in the building exceeds a certain level. But it is not limited to this. In other words, in the present invention, a fine may be collected by the amount corresponding to the premium.

In addition, the present invention used a method of applying a discount to the power bill (electric charge) when the temperature in the building is less than a certain amount. But it is not limited to this. In other words, in the present invention, a benefit (eg, a tax reduction, etc.) may be given by the amount of the discount.

As described above, with reference to the preferred embodiment of the present invention, those skilled in the art will be variously modified and modified within the scope of the present invention without departing from the spirit and scope of the present invention described in the claims below.
