Abstract
A line power control method and system for a unified power flow controller includes outer loop line power control, inner loop valve side current control, and converter valve control. Series-side converter valve side current reference values Iand Iare calculated by means of the outer loop line power control according to line power instructions Pand Qthat are input, a measured line power U, and measured line power Pand Q; a converter output voltage reference value Uis calculated by means of the inner valve side current control according to the valve side current reference values that are output by means of the outer loop power control, a measured valve side current, and a measured valve side voltage; and finally, a converter outputs, according to the voltage reference value, a corresponding voltage to control line power to achieve a reference value.
