【 摘 要 】

The article presents the control algorithms that allow to increase the energy efficiency of the metallurgical production facilities' blow molding mechanisms by impacting on the actuating elements of electrical engineering complexes. A mathematical model is proposed that allows the calculation of energy efficiency. It is shown that this effect is achieved due to: a systematic approach to the design of electrical systems; the use of new types of electric machines; selection of control and regulation algorithms; transition of unregulated control systems to adjustable electric drives; rational choice of elements of electrical systems; increasing the level of staff skills. Energy efficiency assessment was performed for the object, which proposed the mutual influence of the elements of the system. The proposed control laws were compared with systems based on unregulated electric drives and structures in which the air flow was controlled by the guide vanes. It has been established that while transitioning to new control algorithms, it is possible to reduce losses in the system by about 35%.
