This paper refers to modeling, simulation and analysis of doubly fed induction generator for wind turbines. This paper presents the modelling of DFIG based WT system and the simulation results performed for the system developed in Simulink environment of MATLAB . A gird connected wind energy generation model is developed and simulated for normal operation and for some faults in the grid. the an...

in this paper optimal torque control (otc) of stand-alone variable-speed small-scale wind turbine equipped with a permanent magnet synchronous generator and a switch- mode rectifier is presented. it is shown that with otc method in standalone configuration, power coefficient could be reached to its maximum possible value, i.e. 0.48. an appropriate control algorithm based on turbine characterist...

Abstract This article is focused on the simulation and implementation of simple fuzzy logic excitation control of a synchronous generator. In MATLAB/SIMULINK is simulated model of the synchronous generator connected to an AC system. A simple fuzzy logic control scheme is simulated for voltage control and generator stabilization. This simulation is compared with the behaviour of the real laborat...

  Objective(s): In nuclear medicine studies, gallium-68 (68Ga) citrate has been recently known as a suitable infection agent in positron emission tomography (PET). In this study, by applying an in-house produced 68Ge/68Ga generator, a simple technique for the synthesis and quality control of 68Ga-citrate was introduced; followed by preliminary animal studies. Methods: 68GaCl3 eluted from the ge...

In this paper, we present a new contribution for the control of Wind-turbine energy systems, a nonlinear robust control of active and reactive power by the use of the Adaptative Backstepping approach based in double-fed asynchronous generator (DFIG-Generator). Initially, a control strategy of the MPPT for extraction of maximum power of the turbine generator is presented. Thereafter, a new contr...
