In order to provide a testing for Wind Energy Conversion Systems (WECS) control strategies, a Wind Turbine Emulator (WTE) was designed and realized. The experimental implementation of the WTE for WECS consists of permanent magnet DC motor controlled by Pulse-Width Modulated (PWM). A DC motor is used to generate speed and torque required by the aero generator (PMSG) for producing electrical power....
in this paper, a simple and low cost single phase seven-level inverter for PV solar pumping system is proposed. The system consists of a dc-dc multilevel boost converter which is utilized for generating three voltages at its output terminal. In addition a dc-ac multilevel converter apt for the engendered dc bus voltages generates seven levels at its output terminal. The proposed system has the advantages...
Generally manufacturer provides the transfer function of the wind energy conversion system. This paper aims to present a sensorless method to estimate the wind speed and determine the power coefficient of the wind energy conversion system. The method is based only on measurements of the current and voltage at the output of the permanent magnet synchronous generator. A spectrum analysis using the Fast...
This paper presents an approach to determine the power coefficient for a standalone wind energy conversion system (WECS) and estimate the wind speed. The knowledge of the power coefficient requires absolutely estimating the mechanical power supplied by the wind turbine of the system. An Extended Kalman Filter (EKF) associated to a PMSG model is used to reconstruct angular velocity and position. Generally...
In this paper, we present a study for modifying the topology of ENSET Mohammedia Morocco wind generator system. The electric energy storage is substituted by a boost chopper. Thus the electric power and DC output voltage became depending to the duty cycle of the boost chopper. The main proposed control is based on regulation of the inductance current of the boost converter. Finally the electric power...
