The use of gas turbines in the power generation industry has been increasing. Their demand represents more than 50% of the world market of thermal power plants. Electric power generators using gas turbines as power sources are connected to the turbines thr ...
Many electric power generators use gas turbines as power sources. Typically they are connected to the turbines through a mechanical gearbox in order to adapt their synchronous speed to the optimal rotation speed of the turbine, which is very often much hig ...
Many electric power generators use gas turbines as power sources, coupled through a mechanical gearbox in order to adapt their synchronous speed to the optimal rotation speed of the turbine. This paper proposes to replace the mechanical gearbox with a flex ...
The principle achievement of this contribution is to develop and to describe a rapid DC component elimination strategy for AC currents in the frequency converter, simply by selecting transient period. To avoid DC component on the line current, it’s known t ...
The aim of the present paper is to describe a new control strategy for a three level NPC converter connected to the grid, characterized by its high efficiency. This efficiency is achieved using a square wave modulation or SWM, which has the advantage of a ...
In this paper a High Voltage Direct Current (HVDC) transmission system is proposed, based on using three level three phase (3L3P) converters, coupled through a specific transformer connection in order to benefit from natural and selective harmonic cancella ...
La contribution principale de cet article est la description d'une nouvelle stratégie de commande pour un onduleur NPC à trois niveaux connecté au réseau électrique. Dans cette étude, la commande de l’onduleur est caractérisée par un fonctionnement en mode ...
