1. Power Flow Application on an Air Vehicle Electrical Power System

Recently, aircraft power systems have started to change enabling more electric aircraft (MEA) concept which aims to replace pneumatic, hydraulic systems with electrical ones as much as possible. Based on this approach, required power generation and distribution amount inside a platform increase, where MW level power generation capacities are seen in current commercial aircraft. As a result of this amount of power, there are some key issues for MEA related with power such as quality, sustainability, and power flow. This paper focused on establishing an analyzing environment for studying these parameters. By using load flow analysis based on Newton–Raphson method, voltage magnitudes and angles at each bus, losses and the power flows at each branch were calculated under a given different sample load conditions on a generic commercial air vehicle. Matlab environment was used to analyze the system in this study. Some of the simulation results have been presented and obtained electrical power system values were evaluated.
