САЖЕТАК / ABSTRACT:
The paper investigates the role of advanced use of controlled electrical drives and power lectronics in optimizing energy consumption in industrial processes. These technologies are crucial for enhancing the efficiency, flexibility, and overall performance of industrial processes. The paper emphasizes the principle of minimizing energy losses as the basis of energy efficiency and discusses various strategies for achieving this goal. Variable speed drives (VSDs) are highlighted as essential components for regulating motor speed and torque according to specific application requirements. By adjusting the frequency and voltage supplied to the motor, VSDs ensure that the motor operates at its optimum efficiency point, thereby reducing power losses associated with motors operating at fixed speeds.
Furthermore, the integration of power electronics and sophisticated control algorithms enables electrical drives to perform with exceptional precision and responsiveness, as well as to facilitate energy-saving strategies. The paper also discusses how power electronics devices can be employed to improve the power factor of industrial systems, ensuring more effective utilization of electrical power and reducing losses in the distribution network. Additionally, it highlights the role of advanced control systems and power electronics in managing peak loads efficiently, enabling industrial facilities to avoid costly demand charges and optimize energy usage during periods of high electricity prices. Integrating controlled electrical drives and power electronics with smart grid technologies enables demand response, grid interaction, and energy management strategies that contribute to overall energy efficiency and sustainability.
The paper systematically analyzes the potential energy savings achievable through functional adjustment of drive components to meet technological requirements. It categorizes savings into two main groups: savings achievable through functional adjustment of drive components and savings at each individual component of the drive system. Selected examples are methodically discussed to illustrate these points.
