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 (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
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 Stability Improvement using Static Var Compensator in Power Systems

Abstract This paper investigates the effects of Static Var Compensator (SVC) on voltage stability of a power system. The functional structure for SVC built with a Thyristor Controlled Reactor (TCR) and its model are described. The model is based on representing the controller as variable impedance that changes with the firing angle of the TCR. A Power System Computer Aided Design /Electromagnetic Transients including DC (PSCAD/EMTDC) is used to ....etc

Abstract:
Voltage stability has recently become a challenging problem for many power systems. Voltage instability is one phenomenon that could happen in power system due to its stressed condition. The result would be the occurrence of voltage collapse which leads to total blackout to the whole system Investigation and online monitoring of power system stability have become vital factors to electric utility suppliers. Contingency screening and ranking (CS&R ....etc

ABSTRACT

The load on a power system network is increasing day by day without much enhancements in transmission and or generation capability. This causes the system to operate under stressed condition, even a small disturbance can l ....etc
