Variable voltage and frequency supply to AC drives is invariably obtained from a three-phase voltage source inverter (VSI). A number of pulse width modulation (PWM) schemes are used to obtain variable voltage and frequency supply. The most widely used PWM schemes for three-phase VSI are carrier-based sinusoidal PWM and space vector PWM (SVPWM). There is an increasing trend of using space vector PWM (SVPWM) because of their easier digital realisation and better dc bus utilisation. This paper focuses on step by step development of MATLAB/SIMULINK model of SVPWM. Firstly model of a three-phase VSI is discussed based on space vector representation. Next simulation model of SVPWM is obtained using MATLAB/SIMULINK. Simulation results are also provided.

    [Show abstract] [Hide abstract] ABSTRACT: In this paper, a predictive direct power control (PDPC) method for the brushless doubly fed reluctance generator (BDFRG) is proposed. Firstly, the BDFRG active and reactive power equations are derived and then the active and reactive power variations have been predicted within a fixed sampling period. The predicted power variations are used to calculate the required voltage of the secondary winding so that the power errors at the end of the following sampling period are eliminated. Switching pulses are produced using space vector pulse width modulation (SVPWM) approach which causes to a fixed switching frequency. The BDFRG model and the proposed control method are simulated in MATLAB/Simulink software. Simulation results indicate the good performance of the control system in tracking of the active and reactive power references in both power step and speed variation conditions. In addition, fast dynamic response and lower output power ripple are other advantages of this control method.

    [Show abstract] [Hide abstract] ABSTRACT: This paper proposes an advanced energy management strategy for a stand-alone hybrid energy system. The considered hybrid system includes a photovoltaic panel, a fuel cell, an electrolyzer, a battery bank and a supercapacitor. The proposed power management system aims to control the energy flow within the system and decides the amount of the load power shared with each power source. The system control is implemented in two parts: a central power flow controller that provides overall control of the power system and a local loads controller, which controls the different loads according to the energy balance of the system. The hybrid power system has been tested by simulation using models implemented in Matlab/Simulink software. The simulation is performed over a short and a long period of time in order to evaluate the performance of the dynamic controllers and the effectiveness of the management strategy. For a long simulation period, a house located in the province of Batna (35°33′N 6°10′E) has been taken as a case study with a deep study on real load profile for an average house with all required weather data with respect to the location. The simulation results confirm the efficiency of the proposed control strategy, as it increases the reliability of the system and improves its energy balance.

    • "Vector pulse Width Modulation (SV-PWM) which is used to defined the state of the inverter switching and the voltage vector. SVM is explained in detail in [14] and modeled using MATLAB. Another comparative study was conducted [15] to explore the difference between the conventional DTC and the DTC adding a PI controller, which is used in this thesis to get better reduction the ripple in the resultant flux and torque.

    [Show description] [Hide description] DESCRIPTION: This thesis project studies and compares two of the most commonly used electric driving methods of induction motors (IM). These methods, which have been used for three decades are Field Orientation Control (FOC) and Direct Torque Control (DTC). Theoretical background for both methods is explained. Due to its simplicity of use, MATLAB/ SIMULINK is used to simulate the dynamic model of (IM) and applying both techniques on it. The comparative study of speed, torque, and flux is performed under two cases which are the normal operation and in the presence of voltage-sag and short interruption.
