Modeling and control of VSC-HVDC supplying passive network

Based on the mathematical model analysis of VSC-HVDC under abc reference frame and dq reference frame, the controller of VSC-HVDC system supplying power for passive networks is designed in this paper. Rectifier controller adopts double closed-loop structure. The inner-loop adopts deadbeat control to achieve no-error tracking from the control variable to the given value. The outer-loop adopts constant DC voltage controller and constant reactive power controller to achieve independent control of active power and reactive power. A set of VSC-HVDC physical experiments platform supplying power for passive networks is set up to have the experimental verification. The experimental results indicate that the controller have good control performance and certain engineering application value.
