This paper proposed four stability improvement methods by source-side PWM rectifier for More Electric Aircrafts (MEAs). These stabilization methods are based on injecting compensation signals into the control loop of the source-side PWM rectifier which can omit remote sensor and compensation signal of each load. Besides, they overcome the drawback that load-side active damping methods do harm to load...
Starting an aircraft engine with an electrical machine has been one of the major trends for future aircraft. This paper studies the stability of a permanent-magnet machine (PMM) based aircraft starter/generator (S/G) system. Using control-to-output transfer functions, the stability analysis of this S/G system is thoroughly studied. The impact of the key parameters including the control parameters...
This paper investigates the dynamic stability of a droop-controlled multi-generator system in the more electric aircraft (MEA). Based on the developed state-space model of the potential dc electrical power system (EPS) architecture, the stability boundaries of EPS operation depending on parameter variations including component parameters and operating conditions are investigated. The effect of multiple...
Volume and weight are mostly considered when determining more electric aircraft (MEA) power system architecture in industry. However, stability, which has a great impact on system performance, is often neglected. Constant power loads (CPLs), which take a great portion in MEA loads, have destabilizing effect. This paper compares hybrid AC/DC and HVDC architecture for MEA from the perspective of system...
This paper deals with the coordinated control of load sharing among multiple sources in DC microgrid with energy storage system. The DC electrical power system (EPS) with parallel sources in the more electric aircraft (MEA) are under study in this paper. Permanent magnet synchronous generators (PMSGs) are the main sources to supply power to meet the load demand on board. An adaptive droop characteristic...
This paper deals with the modeling and small-signal stability analysis of a dc-distribution electrical power system (EPS) sourced by a permanent magnet synchronous generator (PMSG). The topology employed here is one of the main candidates for future more electric aircraft (MEA). A detailed mathematical model is developed and comprehensive EPS modal analysis is performed. Eigenvalue sensitivity and...

This paper has details the theoretical background, development and application of a newly developed Automated Stability Assessment Tool for More Electric Aircraft Electrical Power Systems. This tool is shown to provide an easy to use and extremely flexible way for system designers to analyze Electrical Power System stability. It is shown how system parameters can be easily varied in order to investigate...
The presence of constant power loads in novel aircraft electrical power systems may cause overall system instability if a power limit range is exceeded. This paper deals with stability analysis of the proposed aircraft power system in order to determine the power limit range and possible differences when varying system parameters such as DC bus capacitance, electrical frequency, and controller parameters...
