Summary
The E2S is a system that automatically analyzes the occurrence of a problem by receiving information in real-time from when
the protective relays installed in all power facilities of the power plant detect any accident.
This is the system that analyzes the occurrence data of protective relays in real-time through IEC61850 communication protocol
used by protective relays.
This system automatically diagnoses details, such as causes of failure, countermeasures, actions, and operational details, of protection relays through a fault analysis algorithm with the analysis data.

Necessity
Current Systems
- Recently, the Protection Relay is undergoing a generational shift to digital-type IED (Intelligence Electronic Device), and the work related
to the protection system requires experts, and it is difficult to respond to the problems quickly and on- the-spot. - In case of failure of power facilities, the operational information of protection relays is collected manually.
- The internal and external experts are needed to analyze collected data and to carry out follow-up measures.
- In general, analysis of the operating causes of a protective relay results in 6 hours.
- Immediately identify the cause of an accident
- In the event of accidents in which the protective relays operate in the power facilities, the accidents have a very high ripple effect, so it is
necessary to immediately identify the causes of the accident as quickly and accurately as possible.
- Immediately create the report
- In the event of critical accidents when protective relays operate, it is very important to identify the causes of the operation and to identify the
exact causes of the accident, and to prepare reports within a short period of time.
- Skilled technique
- The high level of knowledge and long-term acquired techniques are required to determine the exact causes of power plant accidents where
protective relays operate.
- Immediate on-site solutions
- Due to these problems, it is very difficult for field workers to analyze and report on the causes of operation of power facility accidents in a
short time.
