Active front‐end rectifier modelling using dynamic phasors for more‐electric aircraft applications

Active Front-End Rectifier Modelling Using Dynamic Phasors for More-Electric Aircraft Applications

The More-Electric Aircraft (MEA) has become a dominant trend for next-generation aircraft. The Electrical Power System (EPS) on-board may take many forms: AC, DC, hybrid, frequency-wild, variable voltage, together with the possibility of novel connectivity topologies. To address the stability, availability and capability issues as well as to assess the performance of the power quality and trans...

Using Tk as Remote GUI Frontend for 4GL-database Applications

This is a short report about our experience using Tk as GUI frontend. We wrote a compiler called F4GL , source compatible to the INFORMIX 4GL database language. (4GL means 4th generation language) This language was originally designed to create UNIX database applications with text-terminal output. 4GL programs compiled with F4GL generate Tcl-commands as graphic output (the text output is also s...

Power System Stability Monitoring and Control using Dynamic Phasors

Dynamic Phasors Based Modeling and Stablity Analysis of Droop-Controlled Inverters for Microgrid Applications

System modeling and stability analysis is one of the most important issues of inverter-dominated microgrids. It is useful to determine the system stability and optimize the control parameters. The complete small signal models for the inverterdominated microgrids have been developed which are very accurate and could be found in literature. However, the modeling procedure will become very complex...

Active Packaging for Food Applications - A Review

The purpose of food packaging is to preserve the quality and safety of the food it contains from the time of manufacture to the time it is used by the consumer. Recently, the demand for safe and high quality foods, as well as changes in consumer preferences have led to the development of innovative and novel approaches in food packaging technology. One such development is the active food packag...
