Abstract

Wind energy systems have become a highly practical kind of renewable energy, which requires the development of more advanced control mechanisms to enhance efficiency and dependability. Five-phase machines provide several advantages compared to standard three-phase systems in this particular situation. These advantages include reduced torque variation, improved ability to handle faults, and increased capacity to handle power. The Direct Torque Control technology has attracted considerable interest for controlling five-phase squirrel cage induction generators employed in wind energy conversion systems. The main goal of DTC is to achieve efficient energy extraction from the wind by regulating torque and flux without the need for complex transformations and decoupling mechanisms, as required in field-oriented control. DTC is known for its simplicity and fast response, enabling high dynamic performance. This work introduces the notion of predictive torque control as a sophisticated control method for five-phase asynchronous generators in wind energy systems. to attain accurate control of stator flux torque control in the generator, which directly affects the efficiency of power generation. It use predictive modelling to forecast the future torque needs of the generator, allowing for proactive modifications of control parameters to meet the expected demands. It improves power generation efficiency by precisely forecasting torque changes, minimizing torque ripples, and optimizing the generator's reaction to varying wind conditions. It facilitates accurate and efficient torque management, resulting in enhanced overall system performance. In this paper implementing predictive torque control in five-phase asynchronous generators in wind energy systems provides substantial advantages in terms of maintaining stator flux at its rated value, precise torque control, dynamic responsiveness, and reduced harmonics in stator currents.
