Basic Project Data
Project Name: Vibration Protection and Monitoring System
Investor: “Hidroelektrane Đerdap” Kladovo, Serbia
Object Name: “Vlasinske HE” Surdulica, “Vrla 1″ Hydro Power Plant, 1A, 1B, 1C and 1D Units
Installed Power/Turbine Type: 2×11.2 MW; 2×14.5 MW/Pelton
Object Location: Surdulica, Serbia
Brief Project Description: Vrla 1 HPP has four units with Pelton type turbines. The total installed power of the power plant is 50MW. This project is realized as part of the rehabilitation of the HPP control system. Up to now, delivery, installation and commissioning of four VM-600 monitoring systems by MEGGITT have been completed. Apart from functioning as vibration protection systems independent of SCADA/DCS, all installed systems are also 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 jointly by IMP Automatika Ltd, Serbia, NORTH Point Ltd, NORTH Protection Ltd and NORTH Control Ltd, Serbia.
Below is a schematic map of the units and topology of sensors of the vibration protection system.
