The article solves the problem of the dynamic behavior analysis and development of methods to increase the asynchronous motor response time in the amplitude-frequency control and low-inertia load conditions. The analysis is based on a dynamic model of an electrical machine obtained by the invariant transformation of the three-phase energy flow of the electromagnetic system into a generalized energy flow and replacement of the mechanical load with the electrical resistive-capacitive analog. The classical technique of studying transient responses of nonlinear controlled objects is applied using separate equivalent circuits for the steady state conditions and a free motion under the zero initial conditions. The authors give a general solution for the polynomial coefficients of the eigenoperator of the asynchronous motor's differential equation system. The article studies the dependency of the time constants and the attenuation coefficient of the eigenvalue equation aperiodic and oscillatory links on the electrical machine performance and parameter conditions. The article considers the design concepts of a highly dynamic electric motor drive with quasiindependent excitation of the asynchronous motor. |
