The Energy Management System (EMS) ensures optimal control of the operation of the power generation facilities with the linkage system through the normal information collection and load frequency monitoring of the overall power supply system. With the efficient management of the power system, this large-scale power control system facilitates economic energy management.
In terms of system characteristics, only one EMS system has been built to monitor an entire power system. There are two EMS systems in Korea: one is the central EMS system that controls the whole power system, the other is the Jeju EMS system that controls Jeju Island. Our company manufactured and supplied the Jeju EMS System using domestic technology with proven technological strength.
| Master | Executes total node management, application program, and DB management Converts the acquired real data to calculation point data and alarm/event processing Automatic load frequency control and contingency analysis |
|---|---|
| Dispatcher | Supports various operations including screen display, alarm / event display, and printing report by using the processed information from the master. |
| DB Server | Processes the acquired data from the master and stores it with a specified report form using the relational database Manages the statistical / historical data required by the operator, executes RDBMS, and generates reports |
| FEP | Communicates with field devices such as RTU for data acquisition Transmits the commands from Master, Dispatcher and DB server to the field device in real time Stores the booting file and real time DB of the independent node |
| CNP | Links the related data from the central EMS and the Jeju EMS Configured as a point-to-point method for the data links between each system |
| Economic powerDispatch | In the event that the control data cannot be acquired from the central EMS due to a failure in the link between each system, the Jeju EMS will carry out the economical power dispatch function and control the generator and power line independently. |
|---|---|
| Dispatcher | Function which controls automatically the power generator output level Load frequency control using the local frequency data Optimal distribution control, frequency control, and reserved power calculation using the bidding data of generator output. |
| DB Server | Assumes an accident in a specific power line or generator Simulates a situation arising from the separation of each power line / generator from the entire power line system due to an accident |
