This manual generally describes the ”Manager 300P” Power Management System and provides information regarding configuration, lay-out and basic functions of the system.

3. Configuration

·  S6000 generator protection unit, production of Selco (Denmark);

·  Synchronyser FAS 113DG , production of Deif (Denmark) ;

·  DG control unit (DGCU) based on microprocessor modular set Manager 300, production of Marine Bridge & Navigation Systems (Russia);

·  System control unit (SCUDG) based on TSX Micro controller, production of Schneider Electric, France;

·  Magelis touch screen control and monitoring panel, production of Schneider Electric, France;

4. Units basic functions

4.2. Generator protection unit S6000

·  Electrical parameters measuring:

-  three phase generator voltage;

-  three phase generator current;

-  three phase cosφ;

·  Generator protections:

-  short circuit;

-  overload;

-  overcurrent;

-  reverse power;

-  non essential load shedding.

·  Electrical parameters transmission to CAN bus.

4.3. DG Control unit (DGCU)

·  Prime engine protections:

-  lub oil pressure;

-  water temperature.

·  Canceling a. m. protections;

·  Automatic and remote DG start and stop;

·  Cyclic prelubrication of prime engine;

·  Automatic DG synchronization;

·  Active load sharing;

·  Keeping of network frequency in specified limits;

·  CANopen communication;

·  Installed CAN Bridge module provides:

-  Galvanic isolation of two CAN buses;

-  Coupling the buses with different baud rates;

-  Conversion bus topology to star.

4.4. DG System control unit (SCUDG)

·  Heavy consumer start inhibition if power reserve is insufficient at request receipt;

·  Stand-by DG (DGs) start if power reserve is less than specified value or heavy consumer

start request;

·  DG stopping with preliminary unloading and disconnection if total power is less than

specified value;

·  DG low load stop blocking;

·  DG stand-by start if operating DG is faulty. Unloading, disconnection and stopping of

faulty DG after connection of stand-by one;

·  Stand-by DG (DGs) priority definition;

·  Communication to panel and DGCU’s ;

·  Parameters modification from the panel;

4.5. Magelis control and monitoring panel

·  Provides:

-  Alarm summary pages ;

-  Alarm history pages;

-  Mimic diagram pages ;

-  Trend pages;

-  Touch screen control functions;

-  SCUDG communication by RS-485 (UNI-TELWAY protocol);

-  Parameters modification.
