Title:
GAS TURBINE POWER GENERATING SYSTEM INCLUDING A BATTERY SOURCE FOR SUPPLYING STARTUP POWER
Document Type and Number:
WIPO Patent Application WO2000028191
Kind Code:
A3
Abstract:
A microturbine power generating system (10) includes a battery source (46) for providing startup power. Dc power provided by the battery source (46) is converted to three-phase ac power, and the three-phase ac power is supplied to stator windings (36) of an electrical generator (16) of the system (10). The three-phase ac power causes the electrical generator (16) to operate as a starter motor. An up chopper (254) may be used to reduce the required voltage of the battery source (46). A down chopper (154) may be used to charge the battery source (46) during normal operation of the microturbine power generating system (10). The down chopper (154) can allow the battery source (46) to supply backup power in the event the electrical generator (16) experiences a failure.
