Abstract :
A high-speed phase shifter (HSPS) is proposed to be installed in a distribution line for better voltage regulation performance and other functions instead of the load tap changing transformer (LTC). In the proposed system, the one converter of HSPS is connected with the tertiary winding of three-phase three-winding transformer of the substation or step voltage regulator (SVR) instead of connecting the LTC. The other converter is connected to the series transformer to inject a voltage to the transmission line. The voltage regulation range and the capacity of HSPS have been analyzed theoretically, and the simulations in which the simulation code "PSCAD/EMTDC" is used have been carried out. As a result, it is shown that the voltage regulation range of HSPS is wider than that of LTC even-though the same winding is used, and HSPS is a one of the solution to regulate the voltage of distribution system.
