Study on the Static Load Capacity and Synthetic Vector Direct Torque Control of Brushless Doubly Fed Machines
Abstract: Compared to the doubly fed machine, the brushless doubly fed machine (BDFM) has high reliability and low maintenance requirements. First, by taking the negative conjugation of the control motor variables in rotor reference frame, a state-space model of BDFM is derived. It is then transformed into synchronous reference frame, called synchronous reference frame state-space model (SSSM)....
متن کاملAn Improved Three-level Direct Torque Control Method of Brushless Doubly-fed Machine Based on the Fixed Synthesizing Vector
Article history: Received: 11. 09. 2013. Received in revised form: 17.10.2013. Accepted: 17.10.2013. With the rapid growth of an AC adjusted speed system application, it is necessary to control and reduce harmonic pollution since the problem brought about by the device of power electronics not only blocks the development of power electronics technology, but also causes severe harm in an electri...
متن کاملControl Methods for Doubly-Fed Reluctance Machines
The paper considers aspects of scalar V/f control, vector control and direct torque (and flux) control (DTC) of an emerging cost-effective technology for limited speed range applications the brushless doubly fed reluctance machine (BDFRM). Apart from giving a comprehensive review of the various control methods, its major contribution is the presentation and experimental verification of a sensor...
متن کاملVSC-based direct torque and reactive power control of doubly fed induction generator
This paper proposes a novel direct torque and reactive power control (DTC) for grid-connected doubly fed induction generators (DFIGs) in the wind power generation applications. The proposed DTC strategy employs a variable structure control (VSC) scheme to calculate the required rotor control voltage directly and to eliminate the instantaneous errors of active and reactive powers without involvi...
متن کاملImplementation of a Neuro-Fuzzy Direct Torque and Reactive Power Control for Doubly Fed Induction Motor
This paper proposes a Takagi-Sugeno neuro-fuzzy inference system for direct torque and stator reactive power control applied to a doubly fed induction motor. The control variables (d-axis and q-axis rotor voltages) are determined through a control system composed by a neuro-fuzzy inference system and a first order Takagi-Sugeno fuzzy logic controller. Experimental results are presented to valid...
