  • Substation instrument control system
    Patent number: 8682603
    Abstract: A substation instrument control system is disclosed. The substation instrument control system includes a plurality of transformers that generate a plurality of waveform signals representing electric properties of a substation instrument main body. A merging unit is communicatively coupled to the plurality of transformers and includes a signal processing unit and a control unit. The signal processing unit receives the plurality of waveform signals from the plurality of transformers and converts the plurality of waveform signals to a digital signal. The control unit controls operation of the signal processing unit using a setting data. An intelligent electronic device is communicatively coupled to the merging unit and receives the digital signal from the merging unit.

  • 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.
