Description
The present invention relates to a demanded power metering data collecting system, and more particularly, to a demand metering data collecting system for interworking a collection system for collecting demand metering data with an industrial watt hour meter, Collecting system.
Demand management refers to a service that induces efficient consumption of electricity by the consumers in order to secure the reliability of the power system, thereby deriving the demand reduction and compensating the demand.
From the standpoint of the state, it is necessary to avoid the investment cost of the power plant for stable operation of the national power system.
System operators can maintain reliability of power system through reserving reserves, reduce burdens on sudden load fluctuations, and prevent the surge in power market.
In addition, sales companies will have the effect of lowering the price of electric power market due to the reduction in demand and reducing the purchase cost of electricity.
In addition, consumers can receive incentives for the implementation of demand reduction and receive economic benefits by reducing the cost of electric utilities.
However, there is no study on specific system for demand management, so technology is required.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior arts, and it is an object of the present invention to provide a system and method for providing demand metering data in real time to an Internet collection server by linking a collection system for collecting demand metering data to an industrial watt hour meter .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a demanded power metering data collecting system according to the present invention will be described in detail.
Article 31 (5) of the Electricity Business Act stipulates that demand management companies can conduct electricity trading in the electricity market.
Demand Response The resource trading market refers to the electricity trading market, which tries to reduce the peak when the electricity usage is close to the electricity production limit.
A large-scale consumer is able to trade electricity that is reduced through demand management providers when a demand reduction message is transmitted from KPX.
The demand management company plays a role similar to the securities company in the stock market when it engages in the demand response customers and sets the bidding price and reduction capacity when there is a power load reduction instruction from KPX.
1 is a basic configuration diagram of a conventional demand metering data collection system.
As shown in Figure 1, the acquisition system includes a PT /
Demand Response The participating customer installs PT / CT in the inlet that receives electricity from KEPCO, and transmits the 15-minute power consumption data to KEPCO for billing in conjunction with KEPCO's industrial watt-hour meter.
KEPCO's industrial watt-hour meter has a communication port for sending billing data to KEPCO and a pulse output port for extra billing.
The pulse output port is used by most demand response customers to monitor their own power usage.
2 is another configuration diagram of a conventional demand metering data collection system.
That is, PT / CT (100) which is installed at the inlet receiving electricity to KEPCO and is lowered to a measurable voltage and current for measuring a high voltage;
An industrial watt hour meter (200) including a communication port for outputting measurement data and a pulse output port for outputting a pulse for sending billing data to KEPCO;
A pulse splitter (300) coupled to the pulse output port for coupling pulses to a collection server and a power monitoring system;
A
And a
As described above, when the collection server is directly linked to the pulse output port of the industrial watt hour meter installed at the customer site, or when the pulse output port is being used, the pulse distributor is configured to be interlocked.
Accurate data collection is possible because KEPCO works directly with the watt-hour meter used as a billing standard.
However, since it is linked with KEPCO's industrial watt hour meter in electric / telecommunication system, it is likely to affect the customer site and the charge of KEPCO, or cause trouble.
FIG. 3 is another configuration diagram of a conventional demand metering data collection system.
That is, a first PT / CT (100) which is installed in an inlet receiving electricity to a KEPCO and is lowered to a measurable voltage and current for measuring a high voltage;
A first industrial watt hour meter (200) connected to the first PT / CT and including a communication port for outputting metering data for sending charging data to the KEPA and a pulse output port for outputting a pulse;
A second PT /
A second industrial watt hour meter (700) connected to the second PT / CT for sending demand electric power metering data to the Internet collection server;
A
And a power monitoring system (500) connected to the first industrial watt hour meter for monitoring power usage.
The first PT /
In other words, PT / CT and industrial watt hour meter are added to customer site.
In this case, it becomes a system that operates separately from the existing KEPCO owned industrial watt hour meter.
However, as high-pressure water supply, high PT / CT installation cost of up to several hundreds of millions of won and installation period takes about 7 ~ 10 days, there is a problem that supply of electricity to the customer is interrupted.
FIG. 4 is another configuration diagram of a conventional demand metering data collection system.
That is, PT / CT (100) which is installed at the inlet receiving electricity to KEPCO and is lowered to a measurable voltage and current for measuring a high voltage;
An industrial watt hour meter (200) including a communication port for outputting measurement data and a pulse output port for outputting a pulse for sending billing data to KEPCO;
A
And a
In other words, this method works in conjunction with the power monitoring system operated by the customer site. By constructing the interface with the power monitoring system and interworking with the collection server, the accurate demanded power metering data collection becomes possible.
On the other hand, there is a disadvantage that it causes a difference in the billing between the customer site and the KEPCO, or causes a trouble because it is interlocked with the customer's own power monitoring system in the electric / communication system.
5 is a configuration diagram of a demanded power metering data collection system according to an embodiment of the present invention.
That is, PT / CT (100) which is installed at the inlet receiving electricity to KEPCO and is lowered to a measurable voltage and current for measuring a high voltage;
An industrial watt hour meter (200) comprising a communication port (210) for outputting measurement data and a pulse output port (220) for outputting a pulse for sending billing data to the KEPCO;
A
A
And an optical character recognition unit (400) for converting the cumulative effective power amount image taken by the camera unit into digital numbers and providing the digital number to the Internet collection server.
That is, the system captures an image of a cumulative active power amount from a camera on a screen of an industrial watt hour meter, converts the accumulated active power amount image from the optical character recognition means to a digital cumulative effective power amount value, and provides it to the Internet collection server.
Since it is not electrically communicable with KEPCO or the customer's system, there is no possibility of affecting the billing or causing trouble.
As described above, data collected by the collection server through various methods are provided to the Internet collection server.
As a result, there is an advantage that it is not a significant problem in using the demanded power metering data as compared with the conventional collecting system that is linked with the electric / communication system.
6 is a photograph of an industrial watt hour meter of a demanded power metering data collection system according to an embodiment of the present invention.
That is, as shown in FIG. 6, there is an indicator area, and there is an area for providing a power amount value.
7 is a block diagram of optical character recognition means of a demanded power metering data collection system according to an embodiment of the present invention.
7, the optical character recognition unit (OCR) 400 includes a cumulative effective power amount unique
As shown in FIG. 6, the cumulative effective power amount unique
For example, when '004', the cumulative effective power amount image is photographed by the camera unit.
In other words, the image data may be photographed when the accumulated effective power amount value is 004, or not when the image data is 001, 002, .... or the like, have.
When the cumulative effective power amount
At this time, the
In another embodiment, a program for providing the above-mentioned functions of the optical character recognition means may be mounted on a smart phone, and the information may be acquired through the smart phone.
Through the above-described configuration and operation, a collection system for collecting demanded power metering data is interworked with an industrial watt hour meter to provide demand metering data in real time to an Internet collection server.
It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive.
