Simulation Studies, Ac Variable Frequency Induction Electric Dynamometer Systems

The simulation study of a AC VF asynchronous dynomometer is presented in this paper. According to a real AC VF asynchronous dynomometer system, first step, the paper deducts the mathematic model of the system, and analyzes the system stability on the basis of the 揊irst Method?of Lyapunov Stability, then draws the eigenvalues of the system under the situation of the variation of different parameters, and results in finding the changing regularity of the system stability caused by varitation of variant system parameter; Secondly, sets up a system simulation model in terms of a real power feedback AC VF asynchronous dynomometer system, and emulates different running states of the system, not only analyzes methods of adjusting parameters to improve the working performance in the field of weak flux of the system, but also proves the effectiveness of the methods via simulation; At last, compares the simulation results of the model with the experiment results of the real system, and show the nearly correctness of simulation system, and also confirms the practical usage of the simulation system as an effectively assistant tool in the process of developing and design a real dynomometer system.
