Analysis and assessment of STATCOM's effectiveness in improving transient stability for power system

چکیده
Many of papers refers to study of application for FACTS. Especially for using reactive compensators for 500KV power system in order to increase the static voltage stability margin and transient stability enhancement have considered. However the selection of suitable Var source (STATCOM or SVC) also need to be considered. The purpose of this paper is to solve the above problems in order to suggest a olution of the appropriate shunt compensator for a reality 500KV power system. All the simulations for the above work have been carried out using MATLAB-SIMULINK environment.

Power System Transient Stability Analysis Based on the Development and Evaluation Methods
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...

In this study, a new method for designing the damping controller was proposed to improve the transient power system stability in a single machine network connected to an infinite bus. The STATCOM controller problem in a wide area of the system function was considered as an optimization problem with multi-purpose objective function. Also, the Honey Bee Mating Optimization Algorithm was used to d...
متن کاملEffective 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...
