This paper analyzes the impact of using Gopinath observer on robustness current and torque model predictive controls for three-phase squirrel-cage induction motors. The performance two controllers are compared a magnetic flux estimator based voltage Gopinath’s through simulations dynamic behavior machine when errors introduced in its resistance values.

Three-phase induction motor are one of the most important elements of electromechanical energy conversion in the production process. However, they are subject to inherent faults or failures under operating conditions. The purpose of this paper is to present a comparative study among intelligent tools to classify short-circuit faults in stator windings of induction motors operating with three di...

Abstract— The doubly-fed induction machine used as a wind turbine generator has recently received a great attention from the industrial and scientific communities. The reason is twofold: first, this machine easily produces a fixed frequency voltage from the stator windings when the rotor is driven at variable speed; second, the excitation power electronics converter feeding the rotor windings n...

This paper presents simple and accurate approach to compute the minimum value of capacitance required for initiating the voltage build-up in a three-phase selfexcited induction generator. Based on the steady-state equivalent circuit model different numerical methods for solving frequency are known from previous literature, which are of 6 th order polynomial. In this paper the order of the polyn...

The steady state analytical performance of a line commutated inverter fed three phase synchronous motor under variable speed condition is presented. The firing pulses for six silicon-controlled-rectifiers of the three phase inverter are generated by the control circuit in proper sequence with the help of synchronizing signal derived from the induced electromotive force of the synchronous machin...

The paper presents an electromechanical auto synchronized wind energy conversion system (WECS) for larger penetration of renewable energy sources (RES) in the rural electrification systems. The architecture of the WECS uses two stator windings at power frequency which provides harvesting of power to flow from WECS to load and to grid side when the generated power is in access. Asymmetrical six ...
