A Novel Method for Starting of VSC-HVDC System

Abstract

The voltage source converters (VSCs) are the circuits, which convert the power from one form to the other. The application of voltage source converter is vital in HVDC systems. The voltage source converter technology is employed for the smooth operation of any HVDC system. Hence, the HVDC systems based on VSC are gaining importance compared to the other HVDC systems. The starting up process of HVDC system is associated with large value of current, so a proper method of starting is required for the safe operation of the HVDC system. In this paper, a new and novel method is proposed for the smooth starting of the VSC based HVDC system, which will limit the current successfully with high speed operation.
