Abstract

The invention discloses a modular storage battery aviation power supply starting system. The modular storage battery aviation power supply starting system comprises a 0-70V power module, a parallel connection and boosting starting component, an autotransformer rectifier, a system controller, a control panel and a plurality of power components, wherein each power component comprises a 28V storage battery, a bidirectional direct current conversion module, a single-phase alternating current inversion module and a three-phase rectifier power module. The modular storage battery aviation power supply starting system can be compatible with inputs of a low-voltage storage battery, a common frequency power network and a diesel generator by carrying out modular design and architectural design on a power supply, can output a multi-system power supply, has the advantages of an aviation storage battery starting vehicle and a static variable frequency power supply at the same time and can meet requirements such as maneuverability, redundancy, diversified power supply forms and continuous guarantee of an aviation guarantee power supply. The power module with multiple functions is adopted and organically combined, and all the power supply forms in an existing aviation field can be met by a single power supply.

Description

technical field [0001] The invention belongs to the technical field of aviation support power supply, and in particular relates to a modular battery aviation starting power supply system. Background technique [0002] According to different aircraft models, the external power supply of the aircraft (also often referred to as aviation support power supply) mainly includes 28V / 56V DC power supply, 270V DC power supply, 0-70V DC power supply, 115V / 400Hz single-phase AC power supply and 115V / 200V / 400Hz three-phase power supply. Phase AC power supply and other types. The current aviation support power supply mainly includes two types: linear power supply and power supply vehicle. The linear power-on type is used for fixed-position power supply, and uses a power converter (mostly a power electronic converter) to convert the 380V / 50Hz AC power provided by the power frequency grid (or diesel generator) into various power supply types required by the aircraft , using cable transmis...
