Efficient identification of synchronous machine parameters through the finite elements method

This work proposes a methodology to identify the parameters of a synchronous machine based on the finite element method (FEM). Several offline real-time tests to identify SM parameters are reproduced on a digital platform of a FEM based solver. The proposed methodology is divided into three basic steps: creation of the basic physical geometry of the synchronous machine, development and execution of parameter estimation tests on the digital platform, and post-processing to calculate the parameters from the test results. Simulations are shown for a salient-pole synchronous machine. The proposed method is envisioned to replace the real-time offline tests.
