Description

Power Transaction Volume Automatic Verification System and Method {Method and System for Automatically Verifying Traded Utility Power}

The present invention relates to a power transaction volume verification system and a method thereof, and more particularly, to a power generation value for each generator and the sales power value for each generator announced by the power exchange every hour automatically through the Internet, and the two power values The present invention relates to a system for automatically verifying a power transaction amount and a method for automatically verifying whether an error of a power transaction amount is always constant.

The series of facilities that produce electricity and supply it to customers is called the Electric Power System. The power system forms the core of the electric business, and the contents of the facilities include power facilities that produce electric power, transportation equipment such as transmission lines, substations, and distribution lines for transporting and distributing the generated electric power, and the distributed electric power. It consists of accommodation facilities for consumption in the country.

Power companies must provide high-quality, uninterrupted and inexpensive power. More than just supplying energy, there are strict limits on the quality (keeping voltage and frequency within the specified range). In addition, it should provide quality electricity to the consumer, ideally and without interruption anytime, anywhere.

The power business is divided into four types according to the degree of separation of functions: vertically integrated, power generation competitive, wholesale competitive, and retail competitive. Finally, the retail competitive power structure is ideal for the consumer.

Vertically integrated, one utility company performs all of its power generation, transmission, distribution, sales, and grid operations. In this case, the electric power company is obliged to supply electricity and power transmission and distribution facilities to satisfy the demand for electricity instead of the government monopoly of the business, and the charge is regulated by the government.

Power generation competitive power competition is a form of competition in the power generation sector, where there are a large number of power generation companies, and a single purchasing power company responsible for transmission, distribution, sales, and grid operation purchases all of their power and sells it to customers. do.

Wholesale competitive power trading refers to a form in which a large number of power generation companies and a large number of power distribution providers exist to conduct electricity wholesale trade between them.

Retail competitive power trading is a competitive system in which the principle of complete market competition is applied, and it is a structure that gives power purchase options not only to large consumers but also to general consumers.

In order to perform various types of power trade as described above, the amount of power produced at the power station is converted into data and sent to the power exchange, and the power exchange performs power trade based on the power amount data of each power plant.

By the way, in order to obtain the data of the power generated by the conventional power plant, the manager moved to the generator and connected the laptop computer to the electricity meter in the field, and downloaded the electricity meter data, and downloaded the stored data by hand. The conversion was performed.

In addition, the power amount data measured at the power plant, etc. were automatically transmitted to the power exchange via a modem, the power exchange was carried out based on the power amount data received from each power plant. At this time, the power amount data transmitted to the power exchange is transmitted as pulse data. That is, it is promised that some pulse data is transmitted at 1 W / h for each power plant, and the power exchange counts the pulse data transmitted from each power plant to obtain a power amount value.

However, when the power amount data is transmitted from each power plant to the power exchange, when the value measured at the power plant is converted into pulse data, it is incorrectly converted to an abnormality of the metering device, or the power exchange may measure the power value sequentially for each power plant. When the amount of power of any power plant is missed, the amount of power transmitted from each power plant is different from the amount of power sold by the power exchange.

Therefore, the power trader of the power plant has a laptop computer, which has downloaded the power data from the on-site electricity meter, and then moves to a place where the Internet is available, such as an office, and compares the electricity transaction volume with the measured value published on the Internet by the power exchange. Was performed.

In the above-described process, not only was it troublesome to download the electricity meter data by connecting the notebook computer to the generator facility, but also frequently caused a failure of the interface device connecting the notebook computer and the generator facility. In addition, there is a problem in that a time error occurs in which the time indicated by the notebook computer and the time indicated by the power generation facility are different due to an incorrect operation of the field time of the power generation facility during the download process.

In addition, in order to prevent cost loss due to the difference between the amount of power of the power plant and that of the power exchange, the power trader had to perform the verification of the amount of electricity trade every day. Some power plants, which have only a large number of generators installed, have to be verified once every three weeks, which makes it difficult to carry out accurate verification of electricity trade. In addition, the problem of the loss of the power transaction volume gains has arisen since the power transaction volume cannot be corrected in real time according to the time when an error of the power transaction volume occurs due to the manual transaction verification.

In order to solve the above-mentioned problems, the present invention, the amount of electricity generated by generators and the amount of electricity sold by generators announced every hour by the power exchange are automatically acquired through the Internet, and whether the power transaction volume is error by comparing the two electricity values. It is an object of the present invention to provide a system and a method for automatically verifying a power transaction volume that automatically verifies the system at all times.
