  17. Multi-unit System Applications June 10, 2011 US-RUPS aCM Technology Product Line

  18. Multi-unit System Applications Induction Machine Generator (IMG) Provides Important Advantages Over Synchronous Machines in Multiple-Unit System Configurations • The excitation frequency/phase of the IMG is determined by high-speed • electronic control. • Load frequency/phase is not influenced by rotor speed/position. • Multiple IMGs can be perfectly synchronized with precise electronic frequency control. • Machine speed differences do not cause circulation of real power. • Load steps have no effect on frequency. June 10, 2011 US-RUPS aCM Technology Product Line

  19. Multi-unit System Applications Control Modes: • Connected to utility grid • Tie-inductors of all Rotary units are in parallel between grid bus and load bus. • Power from the grid is shared as a result of the (equal) tie inductors. • IMGs regulate load bus voltage level by providing fast reactive power. • IMGs share reactive power through a voltage droop algorithm. • IMGs provide transient real power for sudden load steps. • Real power for each IMG may be different. Real power for each unit • is limited by the internal control. • Disconnected from the utility grid • Electronic synchronization signal keeps the excitation of all IMGs • precisely locked in phase (and frequency). • Leakage reactance of the IMGs ensures real power sharing. • IMGs regulate load bus voltage level by providing fast reactive power. • IMGs share reactive power through a voltage droop algorithm.

  20. Multi-unit System Applications Normal Startup Sequence – All Units Started From Standstill 1) Stator shorted. Units accelerate to grid-connection speed using grid power drawn through tie inductor. 2) IMG synchronizes to grid and MGCB closes. IMG accelerates to normal standby speed using grid power drawn through tie inductor. When all units are at standby speed, IMG synchronizes to grid again. 3) LBCB in all units close and bypass breaker is opened. June 10, 2011 US-RUPS aCM Technology Product Line

  21. Multi-unit System Applications Transfer Load BusFrom One Unit toAnother Unit A and Unit B initially supply separate load buses from different power sources INPUT BREAKER A opens, putting Unit A in UPS mode. Synchronizing source voltage for Unit A is switched from input voltage of Unit A to LOAD B bus voltage. Unit A synchronizes to LOAD BUS B voltage. BUS TIE BREAKER closes and Unit A LBCB opens. Transfer is complete. June 10, 2011 US-RUPS aCM Technology Product Line

  22. Multi-unit System Applications Transfer of Unitfrom One PowerSource to Another Unit A initially connected to POWER SOURCE A. INPUT BREAKER A opens, putting Unit A in UPS mode (ICCB open). INPUT BREAKER B closes. Unit A synchronizes to POWER SOURCE B voltage. ICCB closes. Transfer is complete. June 10, 2011 US-RUPS aCM Technology Product Line

  23. System Reliability and Availability • Study Case: The Multi-unit Rotary System of 14 Units (N) plus y=2 distributed Redundant Units for a total number of Units n = N+y = 16, a 16-Unit Rotary Power System. • The components for Flywheel RTT were combined using appropriate use factors to a single Unit MTBF (Mean Time Between Failure) of 17.7 years, Notes 1 and 2. • Result: • With a MTTR (Mean Time To Repair) of 8 hours per failure the 16-Unit Rotary Power System Availability is 0.9997. • The Utility Grid MTBF is set at 100 hours and this yields Utility Availability of 0.995 assuming a nominal outage time of 30 minutes. • Combining the Utility Grid and 16-Unit Rotary Power System availabilities yields the 16-Unit Continuous Power System Availability of 0.9999987. • Notes: • 1. This number is in the same range as other published system level data for a Rotary UPS. • 2. Data from the PREP (U.S. Army Center for Public Works Power Reliability Enhancement Program) Database version 4.2. It is referenced in 'Operational Maintenance Data for Power Generation, Distribution and HVAC Components' (Hale, Arno and Briggs, IEEE Transactions on Industry Applications, Vol. 35, No. 2, March/April 1999).
