Description: 对其它几种常用的FACTS器件也设计了阻尼控制器,并同样通过了PSASP下的仿真验证,阻尼效果很好。
- Damping controllers of other kinds of FACTS including TCSC, STAT-
COM and SSSC are also designed, which also have good effect to damping inter-area oscillation by simulation. The
power oscillation between two areas is damped quickly while these FACTS are installed.

Description: Flexible alternating-current transmission systems (FACTS) is a recent technological
development in electrical power systems. It builds on the great many advances achieved in
high-current, high-power semiconductor device technology, digital control and signals
conditioning. From the power systems engineering perspective, the wealth of experience
gained with the commissioning and operation of high-voltage direct-current (HVDC) links
and static VAR compensator (SVC) systems, over many decades, in many parts of the globe,
may have provided the driving force for searching deeper into the use of emerging power
electronic equipment and techniques, Platform: |

Description: In a deregulated utility environment financial and market forces will demand a more optimal and profitable
operation of the power system with respect to generation, transmission and distribution. Power electronic
equipment such as flexible AC Transmission systems (FACTS) opens up new opportunities for controlling power
and enhancing the usable capacity in the existing system. A Static synchronous compensator (STATCOM) based
on the voltage Sourced inverter is a widely used shunt FACTS device. This paper deals with the basic simulation
of STATCOM for two machine system and demonstration of transient stability enhancement using STATCOM
through Matlab/Simulink/Power system Computer Aided design (PSCAD). Platform: |

Description: This project deals with modeling and simulation technique of a Dynamic Voltage Restore (DVR).The DVR is a dynamic solution for protection of critical loads from voltage sags / swells. The DVR restores constant load voltage and voltage wave form by injecting an appropriate voltage. Present novel structure improves power quality by
compensating voltage sag and voltage swells.
The transient response of any natural system is the way in which the response of the system behaves as a function of time. Electromagnetic transient studies have always played an essential behavior of the system in the event of different forms of transient phenomena, which can hardly be achieved by other means. This project addresses the transient studies of electrical networks with embedded, power electronics-based, FACTS and Custom Power (CP) controllers. -This project deals with modeling and simulation technique of a Dynamic Voltage Restore (DVR).The DVR is a dynamic solution for protection of critical loads from voltage sags / swells.

Abstract In deregulated power system, congestion management
is a major problem due to operational constraints.
Flexible AC transmission systems (FACTS) devices can be
a choice to control the power flow in congested lines. This
paper explores the use of two popular FACTS devices,
TCSC and STATCOM for power flow control in electrical
network and their capability to decongest the network. It
suggests the optimal location of TCSC and STATCOM
individually to relieve congestion with minimum power
losses, voltage regulation and cost of the device. The
proposed method has been verified on IEEE-14 bus system
for its effectiveness. Simulation work is carried out in
MATLAB software. Platform: |
