Transient Stability Analysis of a Power System Network Using DIgSILENT PowerFactory Software

Abstract

In this project, we are uncovering the transient stability analysis and the load flow analysis of the interconnected power system. The Gauss-Seidel method is a successive displacement method; it is an iterative method that is used for nonlinear algebraic equations. The principle behind this method is to solve a set of nonlinear equations of the real and reactive power at each node. This method determines the realization of the solution depending on the precision index set for the power inconsistency and continues iterating until the size of an element is less than the specified value. When the solution converges, real and reactive powers are calculated. The DIgSILENT PowerFactory software is used to substantiate the load flow analysis; it provides different load flow calculation methods. Newton Raphson solution technique is used in combination with current or power mismatch repetitions, and the implemented algorithms show excellent stability and convergence. The analysis of DC power flow rectifies the flow of active power and voltage angle, it is indeed very fast and powerful. Multiple iteration levels guarantee convergence under all conditions and optionally change constraints.
