A combined speed estimation scheme for indirect vector-controlled induction motors

In this paper a novel speed estimation scheme, combining sliding mode observer (SMO), model reference adaptive system (MRAS), and feedforward control, is proposed for indirect vector-controlled induction motors. Firstly, an intermediate current …

Prediction of insulating transformer oils breakdown voltage considering barrier effect based on artificial neural networks

The insulating oil performance could be enhanced in high-voltage apparatus using barriers. The importance of the barrier in increasing the dielectric strength of the insulating oils in order to reduce the oil failure stresses had not been …

Estimation of regions of attraction of power systems by using sum of squares programming

This paper presents an algorithm estimating the regions of attraction of power systems based on the Lyapunov function approach where a sublevel set of a Lyapunov function for a target system is used as the estimate. In particular, we focus here on …

Investigation of tracking phenomenon in cable joints as 3D with finite element method

Underground cables are manufactured finite length in terms of commercial use. As the underground cables are produced for commercial use, the length is often insufficient for transmission and distribution lines. Therefore, the cables are added …

Die Auswirkungen der Elektromobilität auf den Strommarkt und die CO2-Bilanz

In der aktuellen energiepolitischen Debatte werden dem Ausbau der Elektromobilität hohe Prioritäten eingeräumt, da mit der Umstellung von konventionellen Fahrzeugen auf elektrische Antriebe große CO2-Einsparpotenziale verbunden werden. So strebt die Bundesregierung bis 2030 6 Mio. zugelassene Elektroautos an. Lesen Sie hier, ob die mit dem Ausbau der Elektromobilität verbundenen Ziele tatsächlich erreicht werden können.
