چکیده
It is widely accepted that transient stability is an important aspect in designing and upgrading electric power system. The objective of this paper was to investigate and understand the stability of power system In this paper, modelling and transient stability analysis of IEEE 9 bus system was performed using POWER WORLD SIMULATOR. The load flow studies were performed to determine pre-fault conditions in the system using Newton-Raphson method. With the help of three-phase balanced fault, the variations in power angle and frequency of the system were studied. Frequency is a reliable indicator if deficiency condition in the power systems exists or not. For three-phase balanced fault, fast fault clearing time was analysed to bring back the system to the stability. Further, comparison between Runga method and Euler method for better results was performed. Hence, impact of load switching on system was also computed so as to bring system to steady state.

Effective transient stability assessment based on composite indices
This paper presents a new composite index to analyze power system transient stability. Contingency ranking in power system transient stability is a complicated and time consuming task. To prevail over this difficulty, various indices are used. These indices are based on the concept of coherency, transient energy conversion between kinetic and potential energy and three dot products of the s...

A novel method to compute the stability region in power system transient stability analysis is presented. This method is based on the set analysis. The key to this method is to construct the Hamilton-Jacobi-Isaacs (HJI) partial differential equation (PDE) of a nonlinear system, using which we can compute the backward reachable set by applying the level set methods. The backward reachable set of...

متن کاملA 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...
