Abstract
The control system is significant for steady and dynamic response of voltage source converter multi-terminal DC (VSC-MTDC) system. The VSC-MTDC system is first built and small signal models of different control modes are deduced. Then the converters in VSC-MTDC system are classified into two types. As for VSCs connected to active networks, design procedures for PI control parameters in outer loop and inner loop are given respectively. Design procedure is also given for VSCs connected to passive networks when AC voltage control is adopted. Simulation results, carried on PSCAD\EMTDC, are presented under various operating states.
