A Novel Power Decoupling Control in the Current-Orient Rotating Frame for Unified Power Flow Controller
This paper analyzes the coupling characteristics of the conventional power decoupling control strategy in the voltage-orient rotating d-q frame. a novel power decoupling control strategy in the line current-orient d-q rotating frame is proposed in the paper. A dual second order generalized integrator (SOGI) open loop phase measure method is introduced to increase current phase measure speed. The results of comparative simulations show that the proposed control method effective weakens the control coupling between active and reactive control loop, enhance the power flow control speed and performance.
