  • SYSTEM AND METHOD FOR CONTROLLING OUTPUT EVAPORATION RATE OF WIND POWER PLANT
    Publication number: 20170298905
    Abstract: The present invention relates to a system and method for controlling an output evaporation rate of a wind power plant. The system includes a wind power plant control unit configured to measure an output value of a wind power plant before a predetermined time from an output control time of the wind power plant, calculate a maximum output value of the wind power plant on the basis of the measured output value of the wind power plant, and distributing individual maximum output values of the wind power plant to individual wind power generators in the wind power plant and a wind power generator control unit configured to control outputs of the individual wind power generators according to the individual maximum output values when the individual maximum output values are distributed to the individual wind power generators.

  • Static compensator apparatus for HVDC system
    Patent number: 7944184
    Abstract: A static compensator apparatus for a HVDC system may control harmonic wave compensation at high passive speed to meet operating characteristics of the HVDC system. A static compensator is turned-on in a normal mode and compensates for invalid power and removes a harmonic wave generated by the high voltage direct current system. A static compensator controller controls an operation of the static compensator. A diesel power generator operates complementarily to the static compensator and being turned-on when the high voltage direct current system starts.
