Basic Project Data
Project Name: Vibration Protection and Monitoring System
Investor: “Drinsko-limske HE” Bajina Bašta, Serbia
Object Name: “Elektromorava” ?a?ak, “Ov?ar Banja” Hydro Power Plant, A1 i A2 Units
Installed Power/Turbine Type: 2.0MW; 4.0MW/Kaplan
Object Location: ?a?ak, Serbia
Brief Project Description: “Ovcar Banja” HPP has two units with Kaplan type turbines. The total installed power of the power plant is 8.26MW. 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. 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.
