ELECTRIC SYSTEM STABILIZING SYSTEM FOR AIRCRAFT

摘要

A power stabilizing device in a system includes as a portion of a power converter section, a second PWM converter provided between a second primary AC bus and a second DC bus in an electric system and configured to perform mutual conversion between DC power and AC power. A power stabilizing control section in the power stabilizing device controls charging and discharging of a secondary battery based on a voltage and a frequency in the second primary AC bus, thereby stabilizing the electric system.

主权项

1. An electric system stabilizing system for aircraft, comprising at least:
an electric system including a DC power supply and an AC power supply as an electric power supply device, an AC power supply bus connected to the AC power supply, a DC power supply bus connected to the DC power supply, and a power converter section for converting AC power from at least the AC power supply into DC power to supply the DC power to the DC power supply bus via the AC power supply bus, the electric system being configured to supply the electric power to an electrified device mounted in the aircraft via the AC power supply bus and the DC power supply bus; and a power stabilizing device for stabilizing an electric power output of the electric power supply device; wherein the DC power supply is configured to absorb regenerative power from the electrified device and transiently supply electric power to the electrified device; wherein the power stabilizing device includes a power stabilizing control section for controlling conversion of the electric power in the power converter section; and wherein the power stabilizing control section causes the DC power supply to be charged and discharged, based on a voltage in the AC power supply bus and a voltage in the DC power supply bus to stabilize electric power in the AC power supply bus and electric power in the DC power supply bus so that the electric system is stabilized.
