Project HPP-09: EPS, “Lisina” PSP PU-1 and PU-2 Units,



Basic Project Data

Project Name: Implementation of Protection and Machinery Monitoring System – “Turnkey Project”
Investor: PE Electric Power Industry of Serbia, Belgrade, Serbia
Object Name: “Vlasinske HE” Surdulica, “Lisina″ Pumped Storage Plant, PU-1 and PU-2 Units
Installed Power/Turbine Type: Two Units, Total 28.6 MW/Francis
Object Location: Surdulica, Serbia
Brief Project Description: “Lisina″ Pumped Storage Plant has two pumps units. The total installed power of the plant is 28.6 MW. Functional scheme of the plant is given on picture below:



This project is realized as part of the rehabilitation of the power plant control system. By now, delivery, installation and commissioning of two Machinery Monitoring Systems (MMS) by MC-monitoring, CH, type Rhino PMS-300® with Orca CMS-500® software have been completed. Both installed systems function as vibration protection systems independent of SCADA/DCS, but they are also integrated into the plant control system as well. Protection levels are set according to ISO 10816-5:2000 and ISO 7919-5:2005 standards. Orca CMS-500® software allows operators to monitor the dynamic state of the plant in real time, as well as archiving and analysis of characteristic dynamic parameters.

Machinery Monitoring System, for each of the pumps, has 25 channels, which include monitoring the following dynamic parameters:

  • Bearing absolute vibration number of sensors: 7 according to ISO 10816-5: 2005
  • Shaft relative vibration, number of sensors: 6 according to ISO 7919-5: 2005
  • The rotor-stator air-gap, number of sensors: 4
  • Rotor axial position, number of sensors: 3
  • Structure absolute vibration, number of sensors: 4
  • Key phasor/RPM, number of sensor: 1

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,
  • IMP Automation & Control Systems Ltd – project preparation, MMS and SCADA/DCS connections implemented,
  • NORTH Protection Ltd, Member of NORTH Group – assemblies, installation and commissioning,
  • NORTH Control Ltd, Member of NORTH Group – quality and quantity control, testing, functional control and settings
