  • Substation automatic control system
    Patent number: 8494684
    Abstract: According to one embodiment, there is provided a substation automatic control system. An automatic power adjusting apparatus activates an automatic voltage adjusting apparatus when a phase tap is controlled. The automatic voltage adjusting apparatus activates the automatic power adjusting apparatus when a voltage tap is controlled. The automatic power adjusting apparatus suppresses the effective power on a transmission line to the value smaller than the prescribed value while the automatic voltage adjusting apparatus is performing an automatic control, thereby maintaining transmission-side system voltage within a tolerant system voltage range.
