Zusammenfassung: | Solar radiation is a major factor to convert energy into electricity, but when the solar rays are not be projected perpendicularly on the photovoltaic cells, this seriously affects the overall performance of this conversion. Several studies have been proposed to resolve this problem while ensuring a minimum investment cost of the entire system, and providing improved efficiency for production. We propose in this paper, a so-called optimal design of a system capable of continuing to lead the solar panel to the optimal position to ensure maximum sunlight and thus improve the overall efficiency of the photovoltaic generation system. A direct flux and torque control (DTC) is then applied to an induction motor (IM) which can develop the torque required to optimize the location of the solar panel when the sun moves on its trajectory. This is justified by the simplicity of this technique especially for its sensorless implementation and its robustness via the development of a desired useful torque, still IM is a dominant device in the industry also robust and less costly. So it's an economic system with a simple implementation, composed of three main parts: the capture of the sun, the rotation of the solar panel and the transmission of this rotation. |
