Power savings obtained with integrated industrial system drives

Numerous scientific and official documents stress that energy efficiency improvements can play a key role in both assuring a sustainable energy future and mitigating climate change through socio-economic development. Last World Summit in Durban concluded that changing unsustainable patterns of energy use is a key area for global action to ensure the survival of our planet. This paper proposes a new Concept of five (5) Essentials of Application Engineering, (5 EAE), which would enable designers, manufacturers, and end-users to consistently design and evaluate any design or retrofits of power converters and/or industrial system drives. Five (5) essentials of application engineering have already been successful in designing and manufacturing integrated industrial system drives (IISD), and has created new basis-of-design for drives in mining and heavy industries in South Africa. 5 EAE, as a concept, produces several collateral benefits: 1) An increased technical and economic performance of processes; 2) The defusing of incipient energy and economic crisis; 3) An improvement of environmental conditions; and 4) The creation of jobs in industries. Consequently, 5 EAE can be used as a model for improving a company´s corporate policies and/or utilities, and government energy policies.
