چکیده :
A transformer is a vital component of the power grid infrastructure as it facilitates efficient transmission, distribution, and utilization of electrical energy, and ensures reliable and uninterrupted power supply to consumers. As the demand for electricity in a power grid increases, additional transformers with higher ratings may be required to handle the increased load. Therefore, the reduction of losses in power transformers is essential for optimizing energy efficiency, reducing costs, and maintaining a reliable electrical grid. Stray loss which is 20-25% of the total load loss of the transformer, can affect power quality by introducing harmonics into the power grid. Stray losses also increase the temperature, and cooling requirement for the transformer. In addition to the cost and performance of the power grid, the lifetime of the transformer is also important, which ultimately depends on the amount of losses. Therefore, to compromise between cost and performance, as well as to guarantee losses, it should be reduced. Magnetic shield is a way to reduce stray loss by creating a low-reluctance path for leakage flux. In this research, the three-dimensional finite element method has been used to accurately calculate the stray losses of structural parts of a 250 MVA power transformer. Factors such as selection, and positioning of magnetic shields are taken into account to minimize energy losses and maximize the transformer’s overall efficiency.
