HVDC Technology for Power System Restoration

    Abstract
  • HVDC is widely used in power systems today. Different from AC transmission systems, HVDC systems have their special capabilities and characteristics. As more HVDC systems are integrated into power systems, startup strategies based on HVDC systems have to be carefully evaluated. In this paper, two kinds of most widely used HVDC technologies, i. e., LCC-HVDC and VSC-HVDC, are introduced. After a brief introduction of structures and control strategies of different HVaDC systems, the black-start capability and black-start sequence are discussed. Moreover, the black-start process of wind farms using LCC-HVDC with STATCOM, as well as VSC-HVDC, is simulated with PSCAD/EMTDC to demonstrate the dynamic performances of the two technologies.
