ACKNOWLEDGEMENT

The dissertation has been prepared based on the vocational trainingundergone in a highly esteemed organisation of Eastern region, a pioneer inGeneration Transmission & Distribution of power, one of the most technicallyadvanced & largest thermal power stations in West Bengal, the Meia Thermal!ower "tation #M$T$!$"%, under D'$( would li)e to e*press my heartfelt gratitude to the authorities of MeiaThermal !ower "tation and Techno (ndia for providing me such anopportunity to undergo training in the thermal power plant of D', MT!"$

( would also li)e to than) the Engineers, highly e*perienced without whomsuch type of concept building in respect of thermal power plant would nothave been possible$ "ome of them are+

The practical e*perience that ( have gathered during the overview training oflarge thermal power plant having a large capacity of .128 MW for LnitR ( to((( in three wee)s will be very useful as a stepping stone in building bright

professional career in future life$ (t gave me large spectrum to utili7e thetheoretical )nowledge and to put it into practice$ The trouble shootingactivities in operation and decision ma)ing in case of crisis made me moreconfident to wor) in the industrial atmosphere$Moreover, this overview training has also given a self reali7ation & handsKone*perience in developing the personality, interpersonal relationship with theprofessional e*ecutives, staffs and to develop the leadership ability in industrydealing with wor)ers of all categories$( would li)e to than) everybody who has been a part of this proect, without
