Simulation of the 3-phase double-feed induction motor (DFIM): a range of stable synchronous operation

A physical system has been simulated so as to obtain parameters as near to the real values as possible, to enable the physical construction of the system to a high precision. The mathematical model of the DFIM-load system with symmetrical supplies, expressed in "dq" variables, can be simulated in various ways. For this work the package SIMNON/sup TM/ was chosen. It is recommended for solving systems of differential equations presented in the form of equations of state, which are one way of modeling an electromechanical system. Some simulated situations are shown, including the stability limits of the DFIM in synchronous operation, which are compared with some experimental results.
