APPARATUS FOR CONTROLLING REAL TIME STABILITY OF VOLTAGE AND POWER IN HVDC SYSTEM

摘要

The present invention is to disclose a real-time power stabilization apparatus of an HVDC system. The real-time power stabilization apparatus of an HVDC system according to the present invention comprises: a real-time stability analyzer which calculates and outputs a DC current variation amount, a DC power variation amount, and a voltage stability index on the basis of valid power, invalid power, DC current, and AC system information; and a stabilization controller which confirms the stability condition of voltage and power on the basis of the output of the real-time stability analyzer to change a sign of an instruction value of current.
