DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a high-pressure and low-pressure intelligent automatic target power management system for energy user convenience using public weather information according to the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the technical scope of the present invention. Will be.

FIG. 2 is a view for explaining the configuration of a high-pressure and low-pressure intelligent automatic target power management system using public weather information according to the present invention.

KEPCO (Korea Electric Power Corporation) meter 100 outputs a power measurement value (WP) and a synchronization signal (EOI) of a high voltage customer.

The existing distribution board 200 is a distribution board that is already installed in a low-voltage power supply, in which voltage measurement means and current measurement means can be installed, and outputs the measured voltage value and current value.

The KEPCO meter 100 is a device that can be installed in a high-pressure room, and the distribution board 200 is a device that can be installed in a low-pressure room.

The input unit 600 receives a power measurement value WP and a synchronization signal EOI from a power meter of a customer (that is, an electric meter) 100 and receives a voltage value PT and a current value (CT). At this time, connection between the power meter 100 and the distribution board 200 and the input unit 600 can be performed by wired communication and / or wireless communication.

The communication unit is connected to a network such as the Internet, for example, and receives public weather information provided by a weather station, for example, every predetermined period, and stores it in a database (DB). The specific period can be synchronized with the data providing period of the weather station.

 Various communication methods such as a mobile telephone communication network, a wired / wireless Internet network communication network, a Bluetooth communication, an infrared communication, and an RFID communication can be applied to the connection of the input unit, the power meter or the distribution board, and the network connection of the communication unit.

The calculating unit 500 calculates the current usage of the consumer based on the information input to the input unit 600 (i.e., the power measurement value WP and the synchronization signal EOI, the voltage value PT, and the current value CT) And calculates a power value. Then, an optimum target power value is calculated using meteorological information (temperature, humidity, etc.) disclosed as public data and provided to the operator. The purpose of this system is to enable the system operator to operate the system automatically or manually according to whether or not the control object (EX.

The communication unit 700 receives the public weather information and the electric power amount data used at the time each time, sends the data to the input unit 600, and communicates the data processing state to various mobile devices.

 The power supply control unit 400 controls power supply to a plurality of power consumption groups in response to a control signal input from the processing unit.

The power consumption group is for managing various electrical apparatuses used in a customer by grouping them into one or a plurality of groups. As an example of the consumption group, it can be divided into an air condition group and a lighting group, as shown in the figure. This distinction is dependent on the type of load of the electric apparatus.

Consumption groups, on the other hand, can be grouped by floor or by compartment of a consumer building. That is, they can be grouped in the manner of the first layer and the second layer, or can be grouped in the manner of an office, a conference room, a toilet and a hallway.

Further, the power consumption group may be grouped by the amount of power consumption of each electric appliance. That is, it may be grouped into a group of electric appliances having a power consumption of less than 100 Wh, an electric appliance group having a consumed electric power of 1 KWh or more, and an electric appliance group having a consumed electric power of 0.1 to 1 KWh.

The processing unit 300 receives the information and the public weather information (temperature, humidity, brightness, and the like) from the electrometer 100 and / or the existing distribution board 200 in the input unit 600, And transmits it to the calculation unit 500 to calculate the presently used power value and also receives the calculated target power value based on the saving target amount.

The received current power value and the calculated optimum target power value may be transmitted to the remote control terminal 900 through the communication unit 700 described later or displayed through a predetermined display means.

On the other hand, if the calculated current use power value exceeds the target power value in the comparison result calculated by the operation unit 500, the processing unit 300 may use at least one or more Lt; RTI ID = 0.0 > a < / RTI > The generated control signal may be transmitted to the power supply controller 400.

In addition, the power supply control by the processing unit 300 can selectively control each consumption group or selectively control each electric appliance in the consumption group in steps.

For example, when the used power amount exceeds the target power value by the first range, the power is cut off for the first time, and when the used power amount exceeds the target power amount by the second range, the power is cut off for the second time . ≪ / RTI >

At this time, the system presents the optimum target power value to the operator, and the operator selects and operates the target power value according to whether the current control load can be controlled or not.

By such a stepwise control method, it is possible to alleviate the electric shock of each of the electric devices, and the use time of the electric device can be maximized even during the power control.

If the calculated current used power value is smaller than the target power value, the processing unit 300 does not limit the power consumption.

The communication unit 700 transmits specific information indicated by the processing unit 300 to the remote control terminals 800 and 900 through a wired or wireless network. The control unit 900 receives information from the remote control terminal 900 and provides the received information to the processing unit 300. The processing unit 300 can control the operation based on the information provided by the remote control terminal 900, modify the target power value held therein, or modify the control method for the consumption group.

The remote terminals 800 and 900 may include a smart phone, a touchpad, a mobile phone, a computer, a remote control, etc. and may include information input to the input unit 600 (i.e., a power measurement value WP and a synchronization signal EOI ), A voltage value (PT) and a current value (CT)), and a calculated current used power value. The remote terminals 800 and 900 may store and process the provided information to control the operation of the processing unit 300. [

On the other hand, the specific consumption group can be set so as not to be subjected to the power control of the processing unit 300 or the power supply control unit 400. For example, with respect to an emergency power generation facility, a safety guidance lamp, a fire detection facility, or the like, the power supply can be set so that the continuous power supply can be maintained even if the presently used power amount exceeds the target power amount.

3 is a diagram showing an example of a target power value set by time. In the intelligent automatic target power management system for high pressure and low pressure using the public weather information according to the present invention, the target power value can be automatically set for each time zone. In FIG. 3, a target power value changing in real time is set so that the power consumption can be managed in real time.

On the other hand, the target power value may be set differently between the first and second days. In addition, the target power value may be set in units of time or on a date basis, and the target power value may be adjusted monthly or seasonally.

The intelligent automatic target power management system for high pressure and low pressure using the public weather information according to the present invention as described above is intended to reduce the energy consumption of the high pressure and low pressure consumer and includes control equipment and operation program and data storage device can do. The operation program can be installed and operated in a computer or a mobile device in a customer or a remote place. This is different from that of the existing maximum power management device installed and operating solely in the high pressure consumer.

On the other hand, a high-pressure consumer can be controlled by a method of limiting the amount of electricity used by receiving a signal from a conventional electric meter and by installing a current transformer in the distribution panel for a low pressure consumer, Or the like.

(6) If you use the method that you control directly (7) It is possible to select and monitor the current status, control status, and power consumption chart for power consumption, (8) (9) On a day when power is not used much (for example, only on Saturday and Sunday, only on Saturday, or on Sunday), the past and present power can be checked by comparing the current day, (10) It is possible to display the power consumption used up to now by a list view or a graph view in units of hourly, daily, and monthly basis. 11) It is possible to add the function of sending the contents of the list view that shows the power consumption used up to now by a file to the set mail, and (12) (13) It is possible to set the illumination time of the processing unit screen to be always on or off after a predetermined time, (14) It is possible to set the IP address and PORT number of the terminal (15) It is possible to individually set the name of each electric appliance in each consumption group or consumption group connected to the electric power supply control unit so that the user can easily set the desired group or appliance (16) The processor may select whether to activate each group or electric appliance (power supply), and to divide the remote controllable part and the remote controllable part And the like.

As described above, this operation program can be driven in the remote control terminal or can be mounted on the processing unit 300 and driven.

An example of reduction of electricity consumption and reduction of electricity rate by intelligent automatic target power management system for high pressure and low pressure using public weather information according to the present invention is as follows.

If low-pressure consumers normally operate 6 air-conditioner 3 kW for 8 hours and 3 months a day, the power consumption is calculated as 3 kW × 6 units × 8 hours × 30 days × 3 months = 12,960 kW, × 120 won = 1,555,200 won.

On the other hand, when power is controlled for 4 hours by using the target power management system according to the present invention at low pressure, when the air conditioner 6 kW is operated for 4 hours and 3 months a day, the power consumption is 3 kW x 6 x 4 Hour × 30 days × 3 months = 6,480 kw, and the electricity rate at this time can be calculated as 12,960 kw × 120 won = 777,600 won.

In other words, electricity consumption and electric charge can be reduced by half when compared with 3 months in summer. At this time, if the progressive tax portion is applied, the degree of saving further increases.

In the initial installation of the system, there is no existing data in the database. Therefore, only the weather information provided can be stored in the database and only the peak control according to the target power can be operated. On the other hand, after one year from the installation of the system, the target power value can be automatically set according to the percentage set based on the weather information and power consumption data of the previous year and the current weather information.

The formula for calculating the target power value is as follows.

(Target power value) = {(past power measurement value) / (temperature at the past time) 占 ((temperature at the past time) + ABS {(100- (savings percentage)) / 100}

For example, in the case where the condition at 12:00 on August 30 of the previous year is temperature: 28 ° C, the used power amount is 500 kW, and the condition at 12:00 on August 30 of this year is temperature: 30 ° C, The target power value can be calculated as follows.

The target power value is automatically set to 428.57 kW according to the calculation result. [0054] In this case, the target power value is automatically set to 428.57 kW according to the calculation result {(500 kW / 28 캜) x 28 캜 + ABS (28 캜 - 30 캜)} {(100 - 20) / 100} = 428.57 kW .

As another example, when the condition at 12:00 on December 01 of the previous year is the temperature: 5 ° C, the used power amount is 400 kW, and the condition at 12:00 on December 01 of this year is temperature: 4 ° C, Is 10%, the target power value can be calculated as follows.

= {(400 kW / 5 占 폚) 占 (5 占 폚 + ABS (5 占 폚 - 4 占 폚))} {(100-10) / 100} = 432 kW

Therefore, the target power can be automatically set to 432 kW.

The embodiments of the present invention described above are merely illustrative of the technical idea of the present invention, and the scope of protection of the present invention should be interpreted according to the claims. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It should be interpreted that it is included in the scope of right.
