Definitions
- the present invention relates to an electrical architecture for an aircraft.
- DC high voltage electrical distribution networks are suitable for supplying equipment and loads linked to propulsion. These networks are called “propulsion networks”. They have a DC voltage of between 400 Volts and 800 Volts.
- Three-phase AC power distribution networks are suitable for powering passenger service equipment such as amenities, light fixtures, entertainment systems and galleys.
- Three-phase AC electrical distribution networks can have a voltage of 115 Volts or 230 Volts.
- Each three-phase alternating current distribution network is supplied by an independent alternating current generator.
- Each alternating current generator is sized so that, in the event of a failure of a generator on another network, it can support at least part of the loads on the other network. Switches connected between the networks and between the generators make it possible to supply a network by a generator of another network.
- the frequency of the alternating voltage generated by each generator is a function of the speed of the turbomachine. Consequently, the various generators constituting the alternating voltage sources are at all different frequencies and phases.
- the power supply is cut off for a period of 20 to 30 milliseconds when connecting a generator to a second AC network. This cut leads to voltage drops of 100 to 200 ms that all equipment powered by the second AC network must undergo.
- the equipment is designed to accept these voltage holes with either reservoir strategies energy or restart as quickly as possible to disrupt the operation of the aircraft as little as possible because reconfigurations of the electrical network can occur on the ground but also in flight.
- a first object of the present invention is to propose an electrical network architecture making it possible to avoid these voltage holes.
- a second object of the present invention is to propose an electrical network architecture that is optimized from a mass, cost and efficiency point of view.
- the subject of the present invention is an electrical architecture for an aircraft comprising:
- first propulsion electrical distribution network suitable for distributing a high DC voltage
- the first propulsion electrical distribution network comprising at least a first electrical distribution box
- the second propulsion electrical distribution network capable of distributing a high DC voltage, the second propulsion electrical distribution network comprising at least one second electrical distribution box,
- an electronic unit connected to the first inverter and to the second inverter to control the frequency of the three-phase alternating voltage generated by the first inverter and the frequency of the three-phase alternating voltage generated by the second inverter.
- the electronic unit can easily control an inverter so as to synchronize the frequency of the first alternating electrical distribution network and of the second alternating distribution network. Consequently, in case of connection failure of the second propulsion network, the second AC network can be directly connected to the first propulsion network without it being necessary to wait for a discharge of the electronic components of the second AC network. Similarly, in the event of failure of the first propulsion network, the first alternating network can be directly connected to the second propulsion network. Thus, there is no longer any voltage gap on the AC networks.
- the first propulsion network and the first alternating network balance each other and operate at an operating point optimized with respect to losses.
- the second propulsion network and the second alternating network operate at an operating point optimized with respect to losses.
- the characteristics set out in the following paragraphs can, optionally, be implemented. They can be implemented independently of each other or in combination with each other: -
- the electronic box is suitable for slaving the phase of the alternating voltage generated by the second inverter to the phase of the alternating voltage generated by the first inverter.
- the electronic box is suitable for controlling the synchronization signals of the alternating voltage generated by the second inverter to the synchronization signals of the alternating voltage generated by the first inverter.
- the first inverter and the second inverter are controlled to generate an output three-phase alternating voltage at a frequency of 400 Hertz.
- the fixed frequency of 400 Hertz makes it possible to size all the loads with magnetic components (motors, pumps, voltage transformer, etc.) as precisely as possible, which no longer have to take into account the low frequency of 350 Hertz. This results in a mass gain of around 10% for voltage transformers.
- the motors and pumps can be dimensioned at their operating point at 400 Hertz. Thus, they can operate at their optimum operating efficiency.
- At least one inverter among the first inverter and the second inverter is a reversible inverter.
- the reversibility of the first inverter and/or of the second inverter makes it possible to supply electrical energy to the first and/or to the second propulsion electrical distribution network, for example using an auxiliary group of Powerful.
- This electrical energy can be stored in the accumulators or supply the power distribution box of the propulsion electrical distribution networks.
- This electrical energy can also be transmitted to electrical machines operating in motor mode.
- the architecture includes:
- a second switch capable of connecting the second propulsion electrical distribution network to the second alternating electrical distribution network
- At least one third switch capable of connecting the first alternating electrical distribution network to the second alternating electrical distribution network.
- these switches make it possible to connect the first alternating electrical distribution network to the second propulsion electrical distribution network in the event of failure of the first propulsion electrical distribution network.
- these switches make it possible to connect the second alternating electrical distribution network to the first propulsion electrical distribution network in the event of failure of the second propulsion electrical distribution network.
- the architecture comprises a connection box adapted to be connected to an auxiliary power unit, said connection box being connected between the first alternating electrical distribution network and the second alternating electrical distribution network.
- the first propulsion electrical distribution network further comprises a first accumulator connected to the first inverter.
- the electrical energy stored in the first propulsion electrical distribution network can be used by the first and possibly the second alternative electrical distribution network if necessary.
- the architecture includes:
- turbomachine having a low pressure shaft and a high pressure shaft
- the first electrical distribution box is powered both by an electrical machine coupled to the low-pressure shaft and to an electrical machine coupled to the high-pressure shaft.
- This cross-connection provides greater redundancy and greater fault tolerance.
- the architecture further comprises a second low-pressure electric machine coupled to the low-pressure shaft of the turbomachine and a second high-pressure electric machine coupled to the high-pressure shaft of the turbomachine, the second low-pressure electric machine and the second high-pressure electrical machine being connected to the second electrical distribution box.
- At least one low-pressure electric machine and at least one high-pressure electric machine are reversible electric motors.
- the electric motors can operate in generator mode to supply the first electrical distribution network or in motor mode to supply torque to the turbomachine.

They generate an alternating current which is rectified by rectifiers, not shown, to form a high DC voltage generally between 400 Volts and 800 Volts. This high DC voltage supplies the first propulsion network 16 and the second propulsion network 18.
- the low-pressure electric machines 8, 10 and the high-pressure electric machines 12, 14 consist of reversible electric motors. They can thus operate in engine mode to assist the turbomachine during particular phases of flight.
