Reactive Power Control and SVG Coordinated Control Method for HVDC Transmission System

Abstract This paper proposes a reactive power and SVG coordinated control method for HVDC transmission system. The includes calculating the ΔQ exchanged between converter station AC Set dead zone range of limit output ΔQ. restriction condition SVG’s ability to adjust judge whether emitted by is restricted. Based on sent limited limitation results ΔQ, input PI controller in QPC module calculated complete power, process. When this adopted, operating time greater than rated angle significantly reduced, loss effectively reduced. Meanwhile, DC voltage rise fall are stabilized, fluctuations due passive switching greatly
