Strict environmental regulations and shrinkage of fossil fuels necessitate the generation of electrical power by using renewable energy sources. Wind energy is the most promising and popular source of green electricity. Wind energy conversion systems using SCIGs with full scale power converters is a meritorious option as these generators are simpler than(More)
Transformer fault diagnostic methods based on dissolved gas analysis (DGA) using artificial neural network (ANN), fuzzy logic & a self-adaptive neuro-fuzzy inference system (ANFIS) has been presented in this paper. Firstly, a fuzzy system development technique is proposed, in which the rule base is derived from IEEE and IEC DGA standards. The second(More)
Permanent magnet Synchronous Generators (PMSG) are becoming popular for wind energy conversion systems (WECS) nowadays due to the possibility of gearless operation even in grid connected mode. However, these systems have serious problems during fault conditions such as over speeding of the generator speed and undue increase in the DC link capacitor voltage.(More)
