چکیده

The paper presents a method for finding out the weakest bus based on reactive power sensitivity index for a multibus real system. The Voltage Stability Margin (VSM) and change in voltage has also been calculated for the verification for with and without compensation. These techniques are tested on the 400 KV WBSEB system proposed in the 9th plan and results are given to prove the effectiveness of the proposed methods.

A Nonlinear Voltage Stability Index based on Vector Analysis Method and Measurements of Active and Reactive Powers of Power System

This paper proposes a new voltage stability assessment method based on vector analysis method. This index extraction process relies on measurements of active and reactive powers from connected buses to the generator buses. Therefore, a limit for beginning of voltage collapse is determined based on the maximum power transfer theory. On the other hand, when the system requires load shedding, a ne...

A Fast Voltage Collapse Detection and Prevention Based on Wide Area Monitoring and Control

Voltage stability is one of the most important factors in maintaining reliable operation of power systems. When a disturbance occurs in the power system, it usually causes instabilities and sometimes leads to voltage collapse (VC). To avoid such problems, a novel approach called Vector Analysis (VA) is proposed that exploits a new instability detection index to provide wide area voltage stabili...
