Transformer Design Challenges and Simulation Requirements
📌 Three-phase power transformers are crucial components requiring high efficiency, precision, and long operational life in energy distribution networks.
⚙️ Key design issues requiring simulation include calculating magnetic fields, evaluating saturation levels, testing winding configurations ( and ), and determining and resistances/inductances.
📉 Mandatory pre-building analysis includes no-load conditions to extract the equivalent circuit and short-circuit analysis to evaluate high currents and damage risks to the system.
🔥 Critical evaluations involve accurately estimating losses (to reduce heat), predicting temperature and structural deformation, and investigating electric fields to limit insulation breakdown voltages.
EMWorks Simulation Solution Overview
🤖 EMWorks offers an electromagnetic simulation package supporting both 2D (faster iterations for early design stages) and 3D analysis (final validation incorporating 3D phenomena).
🔗 The solution integrates an circuit simulator using linear/non-linear components (resistors, inductors, switches) to model transformer circuits.
🌡️ Multiphysics options allow seamless, coupled analysis—such as magnetic, thermal, and structural—within a single study without data export/import.
🛠️ The package includes the Transformer Wizard, a template-based design tool for automatically generating 3D geometries for single-phase and three-phase transformers, integrated within and .
Simulation Case Study: vs. Connections
⏱️ A transient magnetic solution was performed using EMWorks 2D, first analyzing open-circuit conditions ( connection, input, ) to visualize magnetic field distribution versus time.
⚡ Short-circuit tests revealed higher short-circuit currents and associated winding losses () compared to the connection when using the delta connection ( losses).
🌡️ Steady-state magnetic analysis using 3D allowed for coupled electro-thermal-structural studies to identify temperature hot spots and structural deformations caused by magnetic forces and thermal stress.
⚡ Dielectric failure investigation used electric field analysis; a calculated safety factor compared the electric field against insulation dielectric strength, where a factor $>1$ indicated a breakdown risk.
Transformer Wizard and Software Demonstration
📐 The Transformer Wizard, integrated into , automatically generates 3D geometry templates based on user-defined core and bobbin parameters.
🔄 The (3D) and environments support various magnetic studies: magnetostatic, magnetic, and transient magnetic.
🔄 The software allows parameterization of both geometric variables (e.g., core diameter) and simulation variables (e.g., current, voltage), and supports multi-configuration to compare several design iterations within one model.
📚 The material library includes well-organized linear and non-linear magnetic materials, allowing customization and automatic curve generation based on initial permeability and saturation points.
Key Points & Insights
➡️ Virtual prototyping via simulation is crucial to save money, effort, and time in transformer design, given the high cost of physical prototypes.
➡️ Utilize coupled multiphysics analysis () within a single study to understand complex interactions like heat generation causing deformation.
➡️ Employ 2D simplification early in the design process for faster iteration cycles, reserving 3D simulation for final validation of results.
