Automatic operation system and automatic operation method of upfc connected scada

A system for automatically operating a UPFC(Unified Power Flow Controller) coupled to a SCADA(Supervisory Control And Data Acquisition) and a method for the same are provided to set the operation condition to reduce the loss of the system. An automatic operation system of a UPFC(112) connected a SCADA includes an upper level controller(224). The UFPC is a series/parallel FACTS(Flexible AC Transmission System) apparatus. The UFPC controls the channel variable. The SCADA obtains the line data of the channel and the state data of the UPFC. The upper level controller analyzes the data which is received from the SCADA. The upper level controller sets the optimum operation mode by the channel condition and the optimum reference of the channel variable. The channel variable is the voltage of the channel, the effective radiated power, and the reactive power.
