As a critical component in the power system, the performance of transformers directly impacts energy transmission efficiency and reliability. The transformer core, being the core element of energy transfer, plays a pivotal role in its design. Traditional core design methods rely on empirical rules and experimental approaches, which are time-consuming and offer limited optimization potential. With advancements in computational technology, electromagnetic simulation provides an efficient and accurate method for core optimization, significantly reducing losses and costs while maintaining performance.

Electromagnetic simulation technology enables precise modeling of the electromagnetic field within transformers, allowing for the analysis of flux distribution, loss characteristics, and eddy current effects under various operating conditions. Compared to traditional physical experiments, simulation offers shorter cycles, lower costs, and more intuitive results. Furthermore, electromagnetic simulation can conduct multiphysics coupling analysis, such as evaluating the impact of core temperature rise on magnetic material performance, thus providing more comprehensive design insights.

Core optimization design based on electromagnetic simulation focuses on several key parameters: core shape, lamination method, silicon steel sheet thickness and material, joint locations, and flux density distribution. By adjusting these parameters, designers can reduce no-load losses and noise levels while improving magnetic permeability and mechanical strength. For instance, simulation results can help determine the optimal magnetic circuit design to minimize flux leakage.

In a project for optimizing the core of a small transformer, researchers utilized electromagnetic simulation to redesign the core structure. Improvements included modifying the lamination orientation and joint locations, adopting thinner silicon steel sheets, and adjusting the flux density distribution. Results showed a 15% reduction in no-load loss and a 10dB decrease in operational noise. This demonstrates the significant advantages of electromagnetic simulation in enhancing design efficiency and performance.

Transformer core optimization design based on electromagnetic simulation has been validated in numerous engineering projects, proving its ability to improve both design efficiency and core performance. In the future, with the further development of artificial intelligence and big data technologies, electromagnetic simulation is expected to enable more precise and automated optimization. By integrating new material developments and advanced manufacturing processes, transformer core performance can be further enhanced, providing robust support for sustainable development in the power industry.
