Abstract
The authors propose an experimental search optimization strategy for power consumption control of electric arc production units to maintain their maximum capacity. An EAF-180 modern high-power electric arc furnace is used as an example. The efficient and intelligent optimization of extremal control of electric power consumption at maximum capacity is facilitated by an extremum search method that stores the active power change rate extremum and stops at a set search time when the process reaches an optimal mode. Use of the proposed search method ensures high reliability of electrode transfer operation by near-complete exclusion of a periodic operation mode which is characteristic of known search methods. Bench-scale testing of the search optimizing extremal control was conducted on a computer-based unit representing a single-phase electric arc furnace. The proposed search method focuses on the application of software and regulating microprocessor controllers, does not require considerable expense, and almost fully excludes interference by process personnel in the power consumption control mode of an electric arc furnace.
