SIMULATION OF ELECTRIC POWER SYSTEM SSSC BY METHODS OF INTERCONNECTED CIRCUITS FOR ANALYSIS OF THE VOLTAGE SYNCHRONIZATION MODES OF TWO LINE

Electricity consumers of category 1 are powered from two mutually independent sources. In some cases, power interruption is unacceptable and voltage matching and short-term or long-term parallel operation of two sources are necessary. To analyze the capabilities of static longitudinal compensators for matching the stresses of two power lines, a computer model has been built. Modeling is carried out according to the methodology for calculating systems for interconnected subsystems, which ensures the minimum consumption of computer time. The static longitudinal compensator allows you to match either the phases or the effective values of the voltage of the transmission line. When phase matching the voltages, another device, for example a tapped transformer, matches the root meet square values. When matching the operating voltages of two power lines, the phase matching of the voltages should also be carried out by another device, for example, a phase-shifting transformer.
