      Summary

      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.

      Features

      • - Applies Open-Architecture and a general Database (ODBC, ADO)
      • - Uses real time OS to process real time data
      • - Supports Economic Dispatch and Load Frequency Control to ensure stable power supply and operation
      • - Applies the Contingency Analysis program which simulates the effect of separating the power line and generator in cases of accident
      • - Supports scenario restructuring and accident analysis in the event of an accident.

      Description

      Description
      MasterExecutes 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
      DispatcherSupports various operations including screen display, alarm / event display, and printing report by using the processed information from the master.
      DB ServerProcesses 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
      FEPCommunicates 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
      CNPLinks 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

      Functions

      Functions
      Economic powerDispatchIn 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.
      DispatcherFunction 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 ServerAssumes 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
