Abstract
This paper builds equivalent circuit of multi-terminal DC network composed of different types of converters and multi-termi-nal DC lines, and proposes the control methods of different types of converters and the coordination mechanism of control modes a-mong converter stations in multi-terminal HVDC transmission systems.A general electromechanical transient model of multi-terminal DC transmission system is established, and the model is realized based on the AC/DC power system calculation and analysis software ( DSP) .The results of the model is compared with PSCAD model through an example system.The comparison results show that the response characteristics of the established multi-terminal DC system model are in good agreement with that of the PSCAD model, and the accuracy of the model is verified.关键词
