The growing use of electrical energy in the world leads to new problem concerning the generation of electrical energy. The advent of turbo generators opened a new era in the state of the art of alternator design. High centrifugal forces developed due to higher speed will be a threat to the laminations of the rotor. In addition to that, the traditional rotor is not adaptable for large rating synchronous generators as it is difficult to build with acceptable mechanical stress, rigidity and critical speeds. In order to overcome these drawbacks a Solid Rotor Alternator (SRA) is evolved.

India is world’s fourth largest growing economy. Our currently available power capacity is approximately 40% short of total demand. As a result the State Electricity Boards have to control the power distribution by imposing 'Load Shedding' to Industrial, Commercial and Residual consumers in a phased manner. For sustainable development, the growth in power demand will be never ending.

Multilevel converters enable power conversion technology for high voltage high power applications in today’s power industries. Multilevel converters possess greater advantage but there has not been an industrial boom in the industrial applications in the past decade. Currently there is a tough competition between the classical two level converters and the multilevel converters. Nowadays researchers all over the world are spending greater efforts trying to improve its performance such as control simplification and voltage balancing.

Double fed induction generators are good options for power production in remote areas. Experimental study has been carried out to verify the simulation results for different values of prime mover speed of DFIG keeping the rotor induced frequency constant or rotor induced voltage constant. Genetic Algorithm is used to get the optimized value of the rotor voltage to keep the stator voltage magnitude and frequency constant for different operating speed. Moreover, adaptive neuro-fuzzy inference system (ANFIS) alongwith GA is used to improve the speed of computation. Constant voltage constant frequency based control strategy is exploited to suit i   Read More...
