A New Way to Control a Static Synchronous Series Compensator Using the Parameters of an Electric Arc Furnace Equivalent Circuit

In this study, a new method for controlling a static synchronous series compensator is proposed, which consists in using data on the parameters of the equivalent circuit of the electric arc furnace. In this case, the compensator is used to improve the energy efficiency and electromagnetic compatibility of a particular unit. A relationship was established between the control parameter - the primary voltage of the compensator and the current consumed by the technological plant. Data on the technological plant and the process can be presented for a given relationship in the form of nonlinear resistance and reactance. The installation of a series compensator controlled in this way makes it possible to regulate the unit current consumption without additional current injection. In the course of mathematical modeling of the process using the established dependence, it was found that the proposed solution allows for full or adjustable compensation of reactive power, filtering of current harmonics and excluding the impact of supply voltage distortions on the progress of the technological process.
