Problems solved by technology

In general, the three-phase AC power supply of the airport can be used for power supply near the bridge, but in the case of far away from the bridge and there is no AC power supply, the auxiliary power unit (APU) of the aircraft or the ground diesel engine must be activated. Power generation, so the noise generated is also very large, the energy consumption is also high, the economic cost is huge, and the environmental pollution is relatively large

Embodiment Construction

[0027] Such as figure 1 As shown, the present invention provides a mobile airport ground static variable power supply system, the core part of which is mainly divided into three parts: a high-power rectifier, a power lithium battery energy storage system, and a high-power inverter. In addition, it also includes the system start-up power supply part, the display part with the operation interface, high-voltage output cables and other accessories, and the control part of the system.

[0028] Among them, the high-power rectifier rectifies the external input three-phase alternating current into direct current, and outputs it to the power lithium battery energy storage system or inverter. A preferred rectifier includes several modules combined in parallel in groups, and the output power can be adjusted by increasing or decreasing the number of incorporated modules through the main control system of the system and the controller of the rectifier.

[0029] The power lithium battery e...

Abstract

The invention relates to a mobile airport ground static inversion power source system mainly applied to the field of civil aviation aircrafts and used for supplying power for aircrafts landing on ground in specific working conditions. The system includes a large power rectifier, a power lithium battery power storage system and a large power inverter. The system also includes a start power system,an operation interface and a high voltage output cable. In a charging mode, after three-phase AC is connected to the rectifier, a main control system sends commands to a battery management system through CAN communication so as to close a high voltage relay of the power lithium battery power storage system. The main control system starts a charging module for charging after detecting high voltagesignals. A discharge mode includes three-phase AC on-load, power lithium battery power storage system DC on-load and AC / DC on-load. The invention can solve a problem of power supply for remote boarding gates of aircrafts and is low in noise, small in fossil fuel consumption, free of pollution and discharge and low in economic cost.

Description

technical field [0001] The invention relates to the technical field of power electronics technology and high-power lithium battery energy storage system, and in particular to a technology for applying lithium battery energy storage system in the field of civil aviation aircraft. Background technique [0002] With the large-scale application of power lithium battery energy storage systems in the field of new energy vehicles and large-scale energy storage systems, etc. Compared with other batteries, lithium battery cells have a long service life, a cycle life of more than 2,000 times, a high energy density of 122Wh / kg, and a wide range of raw materials for manufacturing, low cost, and high safety in use. Lithium battery advantages are becoming increasingly apparent. In the field of civil aviation, when an aircraft is shut down for maintenance or waiting for passengers to board, it needs to supply power to the aircraft to meet maintenance requirements or cabin environment requ...
