Project HPP-03: EPS, “Međuvršje” HPP A1 and A2 Units,



Basic Project Data

Project Name: Vibration Protection and Monitoring System
Investor: “Drinsko-limske HE” Bajina Bašta, Serbia
Object Name: “Elektromorava” Čačak, “Međuvršje” Hydro Power Plant, A1 i A2 Units
Installed Power/Turbine Type: 2.5MW; 4.5MW/Kaplan
Object Location: Čačak, Serbia
Brief Project Description: “Medjuvrsje” HPP has two units with Kaplan type turbines. The total installed power of the power plant is 9MW. This project is realized as part of the rehabilitation of the power plant. By now, delivery, installation and commissioning of two Vibration Monitoring Systems (VMS) by Provibtech have been completed. Both installed systems function as vibration protection systems supported by the SCADA/DCS system and are integrated into the power plant control system control system. Protection levels are set according to ISO 10816-5:2000 and ISO 7919-5:2005 standards.

The project has been realized by the following Members of NORTH Group:

  • NORTH Point – delivery of equipment and project realization
  • NORTH Protection – installation and commissioning
  • NORTH Control – testing, functional control and settings

Below is a schematic map of units and topology of sensors of the vibration protection system.
