Addressing the primary characteristics of cycloconverters, which generate not only 5th, 7th, 11th, and 13th order harmonics but also sideband frequencies resulting in rich harmonic content, a filter device solution was selected. The filter type was determined, and engineering design calculations were performed for filter parameters. The TCR+FC type SVC compensates for the imbalance in the rolling mill system by independently controlling phase-to-phase adjustments to regulate capacitive and inductive reactance in the three-phase power supply, thereby reducing losses in the 35KV power grid. Code implementation involves real-time harmonic analysis algorithms and dynamic control logic for reactive power compensation.
