| Abstract: | The mathematical model and control strategy of the VSC-HVDC system are studied. The transient mathematical model for the VSC-HVDC system in dq0 reference frame is developed, and the corresponding decoupled controllers are designed to control the active and reactive powers respectively. In order to testify the proposed controllers, simulations are implemented with PSCAD/EMTDC. The results show that the control system is correct, and the proposed controllers can work well in both the steady and dynamic states. |
| Keywords: | voltage source converter transient mathematical model dq0 reference frame decoupled controllers |
