  1. POWER MANAGEMENT SYSTEM

  2. Presentation overview • Hardware: PMS, generator controller, diesel starter & safety, speed controller & load sharing unit • GENOP 71 • System overview • Power management system functions • Operation and configuration - Screens

  3. PMA 300 Components • Simatic S7-300 components • Touch screen panel MP370 Touch • Generator Controller (GENOP 71) • Diesel Starter and Safety System EC-2(Not part of PMA300) • Speed Controller and Load Sharing unit (Not part of PMA300)

  4. GENOP 71

  5. GENOP 71 Functionality • Monitoring of overcurrent in all phases • Monitoring and trip on short circuit • Monitoring and trip on reverse power • Disconnection of unessential consumers • Automatic synchronisation of the generator breaker (to the bus bar) • Collection, processing and transfer of various measurements to PMA300 • - Active power • -Reactive power • -Generator and bus voltage, three phases • -Generator current, three phases • -Generator and bus frequency • -Power factor • -….

  7. PMA 300 Functionality • Ships network monitoring (blackout, underfrequency…) • Load dependent starting of generator sets • Fault dependent starting of generator sets • - High power and current • - Low frequency and voltage • - External fault (i.e. diesel engine slow down) • Short circuit - and reverse- current protection • Tripping of unessential consumers • Automatic stop on low power • Load demand control (Heavy consumers) • Start and stop order control • Local, Semi Automatic, and Automatic modes • Interface to “third party”: Profibus and Modbus (converter)
