摘要： A system and method for operating a Unified Power Flow Controller (UPFC) connected to a SCADA (Supervisory Control and Data Acquisition) are disclosed. The UPFC automatic operation system receives power system data from the SCADA system, automatically determines UPFC's optimum operation conditions according to power system states. The system includes: a UPFC acting as a serial/parallel FACTS to control variables of a power system; a SCADA for periodically acquiring line data of the power system and state data of the UPFC; and an upper controller for analyzing data received from the SCADA, and determining an UPFC's optimum operation mode for each power system condition and UPFC's optimum set-point control commands.

摘要： A liquid crystal display device and a driving method thereof that are adaptive for detecting a presence and a frequency range of an input signal applied to the liquid crystal display. In the device, a timing controller is provided with a signal presence determiner for detecting an application of an input signal from an interface. The signal presence determiner is provided with an oscillator for generating a reference clock having the same frequency as a horizontal synchronizing signal and a pre-synchronizing signal having the same frequency as a vertical synchronizing signal, a period detector for comparing a data enable signal from the exterior thereof with the reference clock to output a period of the input signal with the aid of a detection reference signal and the pre-synchronizing signal, a period comparator for comparing a period range between a desired maximum value and a desired minimum value of the input signal, and signal presence/absence comparing means for determining a presence/absence of the input signal in response to a pulse number of the input signal detected within a period range between the maximum value and the minimum value during an application interval of the detection reference signal.
