Abstract”
In This paper investigates the impact of a STATCOM operating in a phase imbalanced mode on damping sub synchronous resonance in series capacitive compensated transmission grid. Phase imbalance has the potential of reducing the energy exchange between the electrical and mechanical sides of turbine-generator and, therefore, damps the sub synchronous oscillations resulting from series capacitive compensation.

Abstract”
This paper presents a simplified sinusoidal uninterruptible power supply (UPS) system. The proposed scheme includes features such as high power factor, low total harmonic distortion and good dynamic response at the ac output voltage. In addition, the scheme has the desirable characteristics of high efficiency, simple circuit and low cost compared with a traditional standalone multiple stages UPS with power factor correction. The paper also presents the circuit operation, the analysis and, experimental results of the proposed U ....etc

Fuzzy Coordination of FACTS Controllers for Damping Power System Oscillations

Abstract
This paper concerns the optimization and coordination of the conventional FACTS (Flexible AC Transmission Systems) damping controllers in multimachine power system. Firstly, the parameters of FACTS controller are optimized. Then, a hybrid fuzzy logic controller for the coordination of FACTS controllers is presented. This coordination method is well suitable to series connected FACTS devices like UPFC, TCSC etc. in damping multi-mod ....etc

POWER QUALITY MEASUREMENTS PERFORMED ON
WIND FARMS IN TURKISH POWER SYSTEM
ABSTRACT
The wind farm integration may cause power quality concerns in power systems.
Integration of large scale wind farms into power systems presents some challenges
that must be addressed such as system operation and control, system stability, and
the power quality. Therefore, determining how much the power quality would be
affected by fluctuant power production and by the connection of the wind turbines
to the power system is the most important issue ....etc

VARIATION OF DAMPING RATIO AND SHEAR MODULUS WITH PLASICITY INDEX AND CONFINING PRESSURE

INTRODUCTION
Behaviour of soil under cyclic loading is non-linear

Non-linear behaviour commonly characterised by:

Damping coefficient, D

Shear modulus, G


DEFINITION
Damping coefficient
Is defined as the measure of energy dissipation
Shear modulus
Is the ratio of shear stress to shear strain
Plasticity index
Is the difference between liquid limit and plastic
limit
Confining pre ....etc

Asynchronous connection
The interconnected AC networks that tie the power generation plants to the consumers are in most cases large. The map below shows the European situation.
There is one grid in Western Europe, one in Eastern Europe, one in the Nordic countries. Islands like Great Britain, Ireland, Iceland, Sardinia, Corsica, Crete, Gotland, etc. also have their own grid with no AC connection to the continent. The oth ....etc
