“…In Figure 1 the CFRP impedance is Z c (Ω), the impedance of the DC section of the network, which may include filters, is Z net (Ω), and the impedance of the current return network, which may require to be considered is Z gnd (Ω). The impedance Z gnd (Ω) is expected to be 2 mΩ/m and 8 μH/m [17].…”

“…2, the generator feeder cable to the ATRU has been modelled using a lumped parameter model [20] to represent the bundled phase and neutral cables. The current return network impedance has been represented by a lumped impedance of 2mΩ and 8 mH [2]. There is a capacitive coupling between the cable sheath and ground (1.2 nF per phase), which will conduct stray currents generated by electromagnetic interference [21].…”

“…The continued upwards trend for the use of electrical power on MEA, is resulting in on-board electrical power systems with higher voltage levels, increased use of direct current (DC) and more electrically powered critical loads [1]. In parallel to this there is a trend for the increased use of composite materials, in particular CFRP, for aerostructures, due to the superior mechanical performance of CFRP compared to metallic structures [2]. However, CFRP has a much poorer electrical conductivity than metallic structures [3] [4] and hence cannot form part of the electrical return network on the aircraft, where the ground plane must have a low enough electrical resistance such that the voltage drop over the current return path is negligible [5] [6].…”

The upwards trend for the use of electrical power on state of the art more-electric aircraft (MEA) has resulted in a significant changes to the electrical power system (EPS) for these platforms due to increased use of DC, higher voltage and power levels, and decentralized architectures. A dual trend is the increasing use of carbon fibre reinforced polymer (CFRP) for aircraft structures, due to the superior mechanical properties of CFRP compared to metallic structures. However, the poorer electrical conductivity of CFRP results in the aircraft structure no longer being fully integrated with the electrical power system. There is a need to integrate these two systems to fully maximize the performance benefits of CFRP, and optimize the weight and volume of the electrical power system. A first step in this integration is to identify an appropriate fault management strategy, which enables the detection of higher resistance ground faults through CFRP. This includes the consideration of appropriate grounding topologies. This paper proposes the implementation of a high resistance grounding topology, which enables the detection and location of a fault via spectral analysis of the voltage across the grounding resistor. From this, implications for wider EPS and CFRP designs to enable the reduction in the use of bulky cable harnesses, providing the first step to CFRP becoming an integral part of the EPS, are discussed.

“…Models for phase-balancing have been developed in many applications, such as in aircraft electric distribution systems [10] and in power distribution grids with a high penetration of electric vehicles [11]. Due to its combinatorial nature, the phase-balancing problem is usually solved using heuristics [12] and meta-heuristics [13] as well as expert systems [14].…”

A Mixed-Integer Quadratic Formulation of the Phase-Balancing Problem in Residential Microgrids

et al. 2021

Phase balancing is a classical optimization problem in power distribution grids that involve phase swapping of the loads and generators to reduce power loss. The problem is a non-linear integer and, hence, it is usually solved using heuristic algorithms. This paper proposes a mathematical reformulation that transforms the phase-balancing problem in low-voltage distribution networks into a mixed-integer convex quadratic optimization model. To consider both conventional secondary feeders and microgrids, renewable energies and their subsequent stochastic nature are included in the model. The power flow equations are linearized, and the combinatorial part is represented using a Birkhoff polytope B3 that allows the selection of phase swapping in each node. The numerical experiments on the CIGRE low-voltage test system demonstrate the use of the proposed formulation.
