“…This approach allows the prime movers to be operated at their most efficient speeds [2] and/or the electrical generators to be operated at very high speeds in order to achieve higher system power densities [12]. Also, the paralleling of generators onto a DC bus is easier than for an AC bus, as the requirement for tight frequency regulation of the supply is removed [13].…”

This paper analyzes the behavior of a highly capacitive DC marine network under fault conditions and demonstrates how overvoltages can be caused by the redistribution of stored energy following the clearance of a fault. This energy How can be complex in nature, making it particularly difficult to sufficiently protect the network effectively. Through the analysis and simulation of a representative zonal DC marine network, this paper analyzes the causes and severity of overvoltages which can occur following a fault, identifying key contributing factors. The paper also demonstrates how the effects of a fault on the network can propagate, potentially causing damage to previously healthy parts of the network. Through this analysis, this paper identifies options for the mitigation of overvoltage transients in DC marine electrical systems

On-board electrical systems are the key components of each modern aircraft. They enable its safer, more comfortable, and environmentally friendlier operation. The strict regulations to reduce pollution and noise are produced by aircraft eventuated in projects like Clean Sky or ICAO Global Coalition for Sustainable Aviation. One solution to environmentally friendlier operation is the full electric propulsion of the aircraft, which enables the reduction of both noise and pollution. Such a concept requires a total change of all on-board power systems and enables the profound change in aircraft design. This paper presents the evolution of aircraft power systems into the so-called more electric aircraft (MEA) and discusses the state-of-the-art electrical systems. Furthermore, the concept of all-electric aircraft (AEA) is presented here.

“…2 (i.e. the higher speed ranges) is the realm of the one-body rotor machines such as SR machines and IMs [25] [29]. In the 250kW range, two-channel SR generators developed by GE demonstrate a competitive power density, even against a modern advanced Siemens machine [37].…”

Electrical machines and drives keep moving away from traditional technologies such as brushed machines and wound field machines towards lighter, 'easier to maintain' machines. A very interesting aspect is that certain transport applications, especially the aerospace industry, still favour the classical wound field machine for its main generating system such as the Boeing 787.This paper focuses on investigating this particular trend by presenting a detailed overview of historical power generation systems on aircraft. This paper compares the current state of the art of wound field machines with other generator families. The results of this analysis are then projected into the needs of the electrical power generation and distribution system on aircraft. While power density is a major objective for any aerospace application, however the extra benefits associated with wound field systems are still essential in modern aircraft.The paper then focuses on the main challenges for improving power density of wound field machines. Recommendations, opportunities and improvements related to wound field machines are discussed. In conclusion, if robust designs for higher speed wound field generators were consolidated, it would be very probable that these classical machines might still be implemented on future MEA platforms.
