Optimization Technique for Designing a Power Transformer

Abstract

Power transformer design is large variables multi-objective, time consuming design optimization problem. An optimization of Power transformer design is purposive by minimizing transformer cost, losses, temperature rise and its design making time, and maximizing its efficiency and lifespan by considering constraints imposed by IS specifications, customers application, and manufacturing constraints. By setting proper geometry parameter of transformer designer can minimize the transformer manufacturing cost and to reduce it designer have to select optimal value of volt per turn, core diameter and number of turns while considering constraints limits. In Proposed Methodology to do a Transformer design optimization I used a Cu-fill factor (winding space factor) and Ratio Factor (Height to Width Ratio of Transformer winding) concept by which designer can get Height, Width of different Winding and volt per turn, core diameter and selected number of turns while considering constraints limits. After getting geometric dimension of transformer winding as height and width of winding designer can find a conductor dimension while considering conductor dimension constraint. The main purpose of this work is to develop an optimization technique using successive iteration method to reach a global optimum design of a power transformer.
