| Abstract: | The controllable switching current source converter (CSC) is considered to have promising technological advantages over LCC and VSC. The rapid development of reverse blocking high-power semiconductor devices provides a new opportunity for the application of CSC to HVDC system. Firstly, the advantages and disadvantages of the existing CSC topology and modulation methods are investigated in this paper. And then, the LCC-CSC topology and specific harmonic elimination modulation methods suitable for HVDC system are analyzed. Finally, the LCC-CSC based hybrid HVDC system is comprehensively compared with LCC and VSC technologies, and the technical advantages, existing problems and future researches of LCC-CSC are summarized. This work can provide a research basis for application of CSC in high-voltage DC transmission engineering. |
