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

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

VOLTAGE SOURCE CONVERTER TOPOLOGY FOR HVDC GRID CONNECTION OF OFFSHORE WIND FARMS
ABSTRACT
Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connection to the AC network. HVDC systems based on voltage source converters (VSC) are a promising alternative to conventional AC transmission above a certain cable length. This paper p ....etc

A converter transformer is a main component in the HVDC transmission system. The converter transformer failure is the major cause of worry of electric power utilities. It is the top portions of the secondary windings of the converter transformers that fail leaving the primary winding unaffected. In this article, a practical HVDC system has been modelled to find the the causes for these failures. The MATLAB/SIMULINK environment has been used as the modelling environment. The possible solutions that emerged include providing passive filters on ....etc

12-PULSE HVDC TRNSMISSION SYSTEM BY USING IGBT VALUES


ABSTRACT

In this project an attempt has been made to analyze the effect of Using IGBTs rather than semiconductor devices such as Transistors, SCRs in the converter stations for HVDC transmission.
The main parts of any basic HVDC transmission system are converter stations transmission line and DC switch gear and protection equipment. Till now the main devices that are used in converter stations for the purpose of rectification and inversion are SCRs. B ....etc

Pulse Shape Improvement in Core-Type High-Voltage Pulse Transformers With Auxiliary Windings
High-voltage pulsed power technologies are rapidly emerging as a key to efficient and flexible use of electrical power for many industrial applications. One of the most important elements in high-voltage pulse-generating circuit technology is the transformer, generallyused to further increase the pulse output voltage level. However, its nonideal behavior has significant influence on the output pulse shape.The most attractive winding configurati ....etc
