Abstract
This paper presents a general model of dual infeedHVDC system applying VSC-HVDC, which can be used as anelement in large multi infeed HVDC system. The model may havedifferent structure under different grid faults because of theaction of breakers. Hence power flow of the system based on thismodel is analyzed under steady state and different kinds of gridfault transient situations. Two main control methods applied onVSC-HVDC page link in this dual infeed HVDC system areinvestigated, and comparative analysis of them under transie ....etc

ABSTRACT

Electric power transmission was originally developed with direct current. The availability of transformers and the development and improvement of induction motors at the beginning of the 20th Century, led to greater appeal and use of a.c. transmission. Through research and development in Sweden at Allmana Svenska Electriska Aktiebolaget (ASEA), an improved multi-electrode grid controlled mercury arc valve for high powers and voltages was developed from 1929. Experimental plants were set up in the 1930â„ ....etc

ABSTRACT
Urban electrical power systems with steep demand increase need easily located solutions with short lead time from decision to transmission. While AC cable solutions can offer sufficient power ratings, the problems of load controllability and short circuit power increase with every added circuit. These problems may be countered with Voltage Source Converter (VSC) based technology using Cables for transmission, such as HVDC Light. This technology offers up to 500 MW per station with small footprint, ideal for in feed to city ....etc

Voltage Source Converter (VSC) based HVDC transmission systems are available in market for power rated between a few MVA to a few hundreds of MVA. The new system results in many application opportunities and new applications in turn bring up new issues of concern. This paper aims at exploring the HVDC transmission systems and also presents a comprehensive investigation on one of the concerned issues, which is the contribution of HVDC Light? to short circuit currents. Different AC network conditions, load conditions and fault types are considere ....etc

Abstract
This paper illustrates a study on HVDC Light for itsenhancement of AC/DC hybrid transmission system and multiinfeedHVDC system. In the sense of the realizing independentcontrolling of active and reactive power, HVDC Light is moreeffective compared to the conventional HVDC system. An AC/DCparallel transmission system and a three-infeed HVDC system aremodeled using PSCAD/EMTDC. Simulations corresponding todifferent situations are performed. From the simulation results,HVDC Light is proven to be able to improve the rotor anglesta ....etc
