US 2006/0066112 A1 · Turbogenerator/motor controller with ancillary energy storage/discharge

Abstract

A turbogenerator/motor controller with a microprocessor based inverter having multiple modes of operation with an energy storage and discharge system including an ancillary electric storage device, such as a battery, connected to the generator controller through control electronics. Electrical energy can flow from the ancillary electric storage device to the turbogenerator controller during start up and increasing load and vice versa during self-sustained operation of the turbogenerator. When utility power is unavailable, the ancillary electric storage device can provide the power required to start the turbogenerator. When a load transient occurs, the gas turbine engine and the ancillary electric storage device provide the power required to successfully meet the transient.

Claims73

Dependent claims

A turbogenerator/motor control arrangement for connection to an AC power grid, comprising:

at least one AC generator;
at least one turbine operatively connected to the generator;
a first converter operatively connected to the generator;
a second converter operatively connected between the first converter and an electric utility interface;
and
a DC bus operatively connected to the first and second converters, wherein power is supplied to the DC bus via the second converter during a first starting mode of the turbogenerator and power is supplied to the DC bus by the first converter during the second “generating” mode of the turbogenerator.
