The Speed Stabilization System of Electromechanical Energy Converters in ANSYS Twin Builder

Abstract

The paper is devoted to solving the problem of building a control system for a special electromechanical energy converter, which is due to the inverted structure of the stator and the presence of a solid hollow rotor made of ferromagnetic steel. The task of the control system is to ensure the speed of the rotor's run-up to a given value in a certain time and then maintain it regardless of load fluctuations. The task was solved due to the implementation of Field Oriented Control (FOC) vector control with speed and current controllers and a phase locked loop (PLL). Despite the fact that from the point of view of the electric drive theory, the given task is not new, its solution using only ANSYS Twin Builder blocks is being solved for the first time. The peculiarity of this work is that the electromechanical converter in ANSYS Twin Builder is not presented in the form of a mathematical model and electric machine blocks built into the Twin Builder library, but through the solution of the ANSYS Maxwell 2D/3D coupling project and the ANSYS Twin Builder solver with co simulation, which significantly increases the quality of calculations. The obtained results will be useful for solving similar problems for other types of electric machines, not only for the considered electromechanical converter of the asynchronous type with a solid rotor.
