Project HPP-07: EPS, “Vrla 4″ HPP 4A and 4B Units,



Basic Project Data

Project Name: Implementation of Protection and Vibration Monitoring System – “Turnkey Project”
Investor: Electric Power Industry of Serbia, Belgrade, Serbia
Object Name: “Vlasinske HE” Surdulica, “Vrla 4″ Hydro Power Plant, 4A and 4B Units
Installed Power/Turbine Type: Two Units, Total 25.4 MW/Francis
Object Location: Surdulica, Serbia
Brief Project Description: “Vrla 4″ HPP has two units with Francis type turbines. The total installed power of the power plant is 25.4 MW. This project is realized as part of the rehabilitation of the power plant control system. By now, delivery, installation and commissioning of two “Rhino PMS-300” monitoring systems by MC-monitoring have been completed. Both installed systems function as vibration protection systems independent of SCADA/DCS, but they are also integrated into the power plant control system as well. Protection levels are set according to ISO 10816-5:2000 and ISO 7919-5:2005 standards.

The project is realized jointly by MC-monitoring SA, Switzerland,  IMP Automation & Control Systems Ltd, Serbia, NORTH Protection Ltd and NORTH Control Ltd, both Members of the NORTH Group, Serbia:

  • MC-monitoring SA –  production and delivery of components and assemblies
  • IMP Automation & Control Systems Ltd – project preparation and SCADA/DCS connection
  • NORTH Protection Ltd – installation and commissioning
  • NORTH Control Ltd – quality and quantity control, testing, functional control and settings
