Before implementation:

  • Since 2012 modernization process is ongoing on TPP to improve its control as well as to increase the total power capacity to 83 MW
  • The existing fault recording and automation system is based on Russian equipment that was commissioned in 2002

Project results:

  • There are 88 additional calculated parameters and 420 various warning events which was set up for immediate user notification about changes in technological process
  • Tens of mnemonic diagrams were developed for full detailed control of the processes at TPP
  • Union of disturbance records from 39 devices into single file
  • Monitoring and control of the plant with 1-second data update time. This includes measurements through 380 analogue signals, 624 status signals, normal mode currents and fault currents
  • Display reliable information on the operation of the main TPP scheme
