Modeling and Simulation of Synchronous Reluctance Motor for Pumping Application Using Field-Oriented Control

This paper presents field-oriented control (FOC) strategy to improve the performance of a synchronous reluctance motor (SynRM) drive system. In this article, the synchronous reluctance motor is used to drive the centrifugal pump that requires high power density . A mathematical model of SynRM is formed using dynamic equations of the motor. This motor model is then simulated using MATLAB Simulink. The suggested control strategy is reviewed, and its control performances (flux and current along direct and quadrature axes) are analyzed. Simulation results are presented to show the efficacy of the approach.

Investigation of Direct Torque Control-Based Synchronous Reluctance Motor Drive for Pumping

This paper discusses direct torque control (DTC) strategy for a synchronous reluctance motor (SynRM). In this article, the SynRM is used to drive the centrifugal pump that requires high power density. A mathematical model of SynRM is formed using dynamic equations. This motor model is then simulated using MATLAB Simulink. The suggested DTC control is analysed for different speeds, and the results are illustrated. The control strategy is simulated, and its performance parameters (flux and current along direct and quadrature axes) are analysed. Simulation results of the synchronous reluctance motor (SynRM) and pump are presented in this paper to determine the performance of the drive.

Modelling and simulation of solar photovoltaic fed induction motor for water pumping application using perturb and observer MPPT algorithm

This work focuses on the photovoltaic array fed water pumping system utilizing induction motor with the model developed in Matlab/Simulink. PV system is designed to avail the solar energy by means of Photovoltaic cells. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity. Maximum Power Point Tracking is a technique used to maximize power output from the Photovoltaic module and finally a 3 phase induction motor is driven through it. In this paper a Photovoltaic array is used to run a induction motor that drives the centrifugal pump. The simulink model of the PV array connected to induction motor where MPPT technique (perturb and observable) plays an important role that is developed in MATLAB and the outputs are observed.

Comparative evaluation of pulse width modulation techniques on effective DC link voltage utilization of grid connected inverter

In this paper, comparison between two different Pulse Width Modulation (PWM) techniques employed for three phase voltage source inverter (VSI) is discussed. The three phase voltage source inverter is basic topology used to supply a grid. In this paper we have design a LC filter between the inverter and the grid in order to stabilize the output voltage. The filter gives sinusoidal three phase voltage at the output of the inverter with almost zero/less harmonic distortion. A suitable PWM technique is employed to obtain the required output voltage in the line side of the inverter. The PWM generation techniques used mainly based on sinusoidal based Pulse Width Modulation (SPWM) and Space Vector based Pulse Width Modulation (SVPWM). In SPWM method involves the comparison of the three phase reference modulating signals with a common triangular carrier wave to generate the pulses for the three phases. Whereas, in SVPWM method, a revolving reference voltage vector is provided as voltage reference instead of three phase modulating waves. This paper analyses these two Pulse Width Modulation techniques for grid connected inverter and to study the performance of the same by comprehensively analyzing the simulation results.
