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

NEW TRENDS IN HVDC TRANSMISSION BASED ON ADAPTIVE NEURO-FUZZY INTERFACE SYSTEM (ANFIS)
ABSTRACT
The industrial growth of a world requires increased consumption of energy, particularly electrical energy. This has led to increase in the generation and transmission facilities to meet the increasing demand. In developing countries like India, the demand doubles every seven years which requires considerable investment in electric power sector. The problems of AC transmission particularly in long distance transmis ....etc

BASIC HVDC AND CONVERTER OPERATION



Why HVDC rather than HVAC?
Long distances make HVDC cheaper
Improved page link stability
Fault isolation
Asynchronous link


Inverter operation ( = 140º)
Firing is delayed so much that the entire area enclosed between the voltage waveform and the zero line is of opposite polarity.

The equation written in terms of  is still correct:

Vd=Vdio -0.766-Id. Xc+Er
2
Vd=-Vdio x 0.8609

MODELING AND APPLICATION OF VSC-HVDC IN THE
EUROPEAN TRANSMISSION SYSTEM


Abstract –

The present paper focuses on the technical,
environmental, and economic features of VSC-based
HVDC technologies. The aim is to investigate the impact of
VSC-HVDC on the European power system: specific attention
is paid to the transmission capacity enhancement
attainable in targeted applications. Towards this purpose,
an original steady state model of the VSC-HVDC is presented
and tested. Then, a techno-economic analysi ....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 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
