Method for controlling the generation of electricity applied to an aircraft gas turbine, and device implementing such a method

摘要

A method improving acceleration efficiency of a gas generator of a gas turbine by reducing take-up of electric power, during transition phases, to conserve a sufficiently large surge margin for an operating line. The method increases acceleration/deceleration power of the gas generator by adjusting voltage of an electric network onboard the aircraft. After a phase of starting the gas turbine, voltage of the onboard network is adjusted by a voltage set value controlled by determining unballasting/ballasting status of a main electricity generation source of the onboard network. The status-determining is executed according to demand for taking power to be supplied for propulsion of the aircraft. The status-determining is followed by selecting a voltage set value from plural levels according to the determining the unballasting/ballasting status, and applying the selected set value to a control loop of the voltage supplied to the onboard network.

1. A method for controlling generation of electricity applied to an aircraft gas turbine and output into an on-board network, comprising:
after a phase for starting the gas turbine, regulating a voltage of the on-board network by a voltage set point controlled by determining an unloading/loading status of a main electricity-generating source of the on-board network according to a request for power bleed to be supplied to propulsion of the aircraft; then, by selecting a voltage set point among plural levels according to a determination of the unloading/loading status; and applying the selected set point to a loop for regulating voltage supplied to the on-board network.
