Abstract
Active and reactive powers interact in the process of power line flow regulation for unified power flow con-troller ( UPFC) . To solve the problem, the mathematical model of UPFC is analyzed, and the voltage control and dual closed-loop control method of voltage and current to the shunt converter, as well as three loop decoupling control strat-egy of voltage, current, power to the series converter are proposed from the perspective of transmission line flow regu-lation with UPFC. These controls realize the capabilities of constant capacitor voltage, voltage stability of AC bus and independent active and reactive power flow regulation to UPFC. A grid-connected simulation model of UPFC is estab-lished to verify the effectiveness and feasibility of the control strategy in power flow regulation.关键词
