Abstract—Given a data point set , a query point set , and an integer , the Group Nearest Group (GNG) query finds a subset ( ) of points from such that the total distance from all points in to the nearest point in is not greater than any other subset ( ) of points in . GNG query is a partition-based clustering problem which can be found in many real applications and is NP-hard. In this paper, Exhaustive Hierarchical Combination (EHC) algorithm and Subset Hierarchial Refinement (SHR) algorithm are developed for GNG query pr ....etc

FACTS is a concept introduced by Electric Power Research Institute (EPRI), U.S.A.It is actually a group of advanced transmission technologies that rely on high speed, solid-state electronics, rather than electromechanical devices.

By this concept, the apparent impedance of a transmission line is controlled according to certain algorithm. Thus the power system operation is made more reliable, controllable and efficient. The FACTS system is a promising method, which can be implemented into the system for enhancing system stability by damping ....etc

FACTS:Flexible Alternating Current Transmission System For Cost Effective and Reliable Transmission of Electrical Energy
ABSTRACT:
Flexible alternating current transmission systems (FACTS) devices are used for the dynamic control of voltage, impedance and phase angle of high voltage AC lines. FACTS devices provide strategic benefits for improved transmission system management through better utilization of existing transmission assets; increased transmission system reliability and availability; increased dynamic and transient grid stabilit ....etc

ABSTRACT:
An experience of operating a large AC network like the one in INDIA has shown that a dispatcher today has hardly any control on the power flow in the transmission network and it is more difficult to regulate the power through the transmission lines. But the FLEXIBLE AC TRANSMISSION SYSTEMS (FACTS) could play a vital role in ensuring committed power flow.
FACTS is one of the best ways to reduce the ....etc

IMPROVING RELIABILITY AND PERFORMANCE OF TRANSMISSION LINE USING FACTS TECHNOLOGY


INTRODUCTION :-
As generation and consumption of electricity has grown, investment in the transmission infrastructure has declined. The grid is aging and few new lines are being built, given high cost and permitting delays. The inability to control power flow on the grid results in poor asset utilization and impedes the growth of the energy market. Uncertainties in transmis ....etc
