Precise Voltage Regulation Technology on Load Side of Distribution Network Based on TCSC

Through TCSC technology, the impedance can be adjusted smoothly, the voltage of lines with different parameters or loads can be adjusted, so the load side voltage can be stabilized. In this paper, the differential equation of thyristor conduction time is solved by the method of linear constant system, and the equivalent fundamental impedance of TCSC is derived by mathematical deduction. The series controlled voltage source is used to eliminate the influence of thyristor on voltage drop on the equivalent fundamental capacitive reactance of TCSC. The simulation analysis of TCSC on the voltage regulation of radiation distribution line is simulated to verify that the conduction voltage drop of thyristor will affect the voltage regulation effect of TCSC, and the series receiving voltage source can effectively eliminate this effect.
