Innovative Aspects of Power Transformer Design Optimization

Abstract

Aim: Now a days, its prime important to develop, manufacture and deliver the transformer which can satisfy the customer s specifications with most compatible cost. That means continual improvement; analysis and innovative techniques must need to apply for transformer engineering. Customers are asking high efficient transformers but not ready to pay more. To comply this requirement most powerful optimization techniques to be apply for transformer design. The aim of proposed work to develop software for power transformer design optimization based on protocol using different optimization techniques. Not only to develop a program, but to manufacture and test the transformer at NABL laboratory to validate the technology practically. newline newlineMaterials and methods: This work comprises the Excel based software development for transformer design as per conventional mathematical formulas, industrial code of practice and applicable national and international standards. The optimization methods like GA, PSO, TLBO and the engineering analysis method like FEM is considered for this research work. Self-developed binary encoded GA, PSO and TLBO is applied to drive the transformer design optimization. The multi objective optimization technique is applied for this work to conclude transformer design which has low cost and high efficiency. 15 MVA 66/11 kV transformer design data is referred to develop software based program of transformer design and respective TDO methodology. On the base of developed TDO, the real transformer of 10 MVA 66/11 kV has been developed and tested at NABL laboratory. newline
