In an effort to address growing demands for reliable power infrastructure, Hitachi Energy is leveraging advanced simulation capabilities from Ansys in transformer development. The company applies a multiphysics approach to better understand the interaction between electromagnetic, thermal, and structural phenomena within transformers. Tools such as Ansys Maxwell are used to analyse core losses, leakage fields, and key electrical parameters, while Ansys Mechanical supports evaluation of mechanical stresses under scenarios like short-circuit events.
In addition, PyAnsys, including the PyAEDT library within Ansys Electronics Desktop, is used to automate simulation workflows, enabling efficient model generation, parametric studies, and result extraction. This simulation-driven methodology aims to allow engineers to investigate design variations, assess thermal performance, and validate operational limits. Overall, the approach aims to reduce reliance on physical testing, identify potential design issues earlier, and support compliance with evolving grid reliability and safety requirements.
