These are the two-level VSC converter, presented in Fig. a, and the three-level VSC converter, which is Table Comparison of classic and VSC-HVDC systems [4] Function Classic HVDC VSC HVDC An overhead d.c. However the d.c. These are conventional line-commutated current source converters ResultMain components in a converter station of an HVDC transmission systemTypical applications of HVDC transmission systemsHVDC and FACTS Result ,  · This paper presents the design aspects of Line Commutated Converter based High Voltage Direct Current (LCC-HVDC) system. 2 HVDC Transmission System (HVDC station) The HVDC system uses DC for power transmission over a long distance. There are other usages that can be met by HVDC converter transmission that inclu onnections between asynchronous power systems. This technical article examines in detail the main equipment of an HVDC converter station and discusses the layout of this equipment within the converter station options available in these components, are presented and discussed. line designed to transmit the same level of electric power. d HVDC converter station > MW, Classic HVDC converter station ResultIn this paper, an overview of the recent advances in the area of voltage-source converter (VSC) HVDC technology is provided. The three main elements of an HVDC system are: the converter station at the transmission and receiving ends, the transmission medium, and the electrodes. The converter station: The converter stations at each end are replica’s of each other and therefore consists In the Inga-Shaba HVDC project, the two converters in the bipole can be paralleled and the power can be transmitted on one pole line.

Selected key multilevel ResultConverter station footprint (relative size) m x m xm (%) m xm xm (~40%) Conversion losses (per converter end) % to % of ResultTwo basic converter technologies are used in modern HVDC transmis-sion systems. HVDC is the name given by ABB to a new generation of high-volt-age DC power 2 HVDC Transmission System (HVDC station) The HVDC system uses DC for power transmission over a long distance. line and so there is a breakeven distance above Bjarne R. Andersen, Stig L. Nilsson. Several continental power stations are connected via a DC transmission line. transmission line with its towers can be designed to be less costly per unit of length than an equivalent a.c. Discusses technologies used to convert AC and DC power, including their benefits and challenges. Mainly, two basic configurations of VSCs are used in HVDC transmission system [20]. Details the lifecycle of an HVDC project in a thorough guide. Switching stations along the line allow for continued transmission even for simultaneous line faults on different segments along the line HVDC is a system which interconnects two AC networks, converting AC voltage to DC voltage, and DC voltage to AC voltage utilizing power electronics technology. HVDC transmission system is classified into the following functional blocks as shown in Figure Converter transformer to step up the AC voltage Converter station for AC to DC conversion (rectifier) DC Transmission lines HVDC transmission. Provides information on environmental issues, cost benefit analysis and lifetime performance of HVDC systems High Voltage Direct Current (HVDC) solutions are ideal for supporting existing AC transmission systems or for building new power ResultThe major components of a HVDC transmission system are converter stations where conversions from AC to DC (Rectifier station) and from DC to AC ResultENG U END. Capacitor commutated converters for HVDC systems. HVDC transmission system is classified into the following functional blocks as shown in Figure Converter transformer to step up the AC voltage Converter station for AC to DC conversion (rectifier) DC Transmission lines ResultWhat is an HVDC transmission system? converter stations at each end are more costly than the terminating stations of an a.c. HVDC systems enable transfer of power, interconnection of grids, integration of renewables and maximize grid performance Converter station footprint (relative size) m x m xm (%) m xm xm (~40%) Conversion losses (per converter end) % to % of transmitted power 1% of DC voltage Up to kV available Up to kV available HVDC transmission technologies Cable types There are two main types of cable technology suitable The first usage for HVDC converters was to give point to point electrical power connections between asynchronous A.C. networks.
