Different schemes for connecting a static thyristor compensator (STC) are examined. Research conducted using a simulation model in the Simulink app of the Matlab mathematical package for the DSP-250 and STK-330 MVAr complexes at the metallurgical enterprise MMK Metalurji (Dortyol, Turkey) is presented. Three STC connection schemes, differing from the classical schemes, are analyzed. For each variant, the operating regimes of the thyristor-reactor group (TRG) for which the maximum electric power increase in the working space of the SEAF obtains are determined. An operational algorithm was developed for automatic control of the TRG in order to maintain the normative reactive power factor.
