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 centers. ....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 ( = 140 )
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
However this is usually written in t ....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

pdf files on a novel high step up dc dc converter for a microgrid converter

Abstract

A novel high step-up dc-dc converter for a distributed generation system is proposed in this paper. The concept is composed of two capacitors, two diodes, and one coupled inductor. Two capacitors are charged in parallel, and are discharged in series by the coupled inductor. Thus, high step-up voltage gain can be achieved with an appropriate duty ratio. The voltage stresses on the main switch and output diode are reduced by a passive clamp circuit. Therefore, ....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 t ....etc
