Multi-unit System Applications 18
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.
June 10, 2011
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.

Multi-unit System Applications 19
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.

System Reliability and Availability 23
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 16Unit 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).
