Integrated WEB SCADA System – KEPCO

Altibase enables KEPCO to build a web-based SCADA system to monitor and respond to incidents in real time.

Use Case: Supervisory Control and Data Acquisition (SCADA)

Current Customer: Incheon International Airport Corporation, DOPCO, and KEPCO

Industry: Manufacturing

Who

KEPCO is South Korea’s largest electricity producer.

Problem

KEPCO adopted Oracle databases when integrating its eleven Supervisory Control and Data Acquisition (SCADA) systems in 2011. However, the databases presented numerous problems because of their slow performance.

The databases were not able to remit data collected from terminals to the control center in real time.

The data contains information on electricity demand from each region. Without the information, KEPCO would have difficulty in providing adequate electricity to places where there is a shortage.

With Oracle databases, KEPCO was only able to collect two batches of electricity consumption data in a day, which was not enough to analyze where electricity was distributed and consumed.

Consequently, the SCADA systems were not able to function properly because of the bottleneck caused by Oracle databases.

Solution

KEPCO has adopted Altibase since 2013. Altibase’s hybrid architecture has enabled KEPCO to detect data abnormalities in real time with non-stop service by continuously updating hot or frequently used data and gradually migrating hot data to disk tables.\

Results

Real time collection and analysis of a wide array of data is possible with Altibase. The data includes temperature abnormalities, natural disasters, human error and power loss.

KEPCO reduced TCO by 33.3%.

Data is processed 10 times faster than Oracle databases.

Power is analyzed and distributed across the nation in real time.
