Impedance Bus Matrix Formation using Bus Building Algorithm for Power System Analysis

Abstract

The mainstay of power system design and analysis is Power Flow analysis. The prime idea of power flow examination is to discover the phase angle and magnitude of voltage at all buses and the reactive and real power flow in individual transmission lines involved. This analysis is a significant tool that involves arithmetical study applied to a power system. It is known that the technique for attaining the Z bus matrices (impedance matrix) in any casing of orientation necessitates matrix transformation comprising multiplications and inversions. It could be very arduous and long standing method for enormous systems linking hundreds of buses or nodes. Such an algorithm would be very expedient for several outsized systems that may be desired while the system is running such as change in parameters, elimination of lines and addition of lines. The bus impendence matrix could be directly set up, by means of a building algorithm, and examination of a huge number of bus system could be performed effortlessly. Formation of Z Bus matrix is performed by taking a contextual analysis of 110/33 KV substation of 14bus by utilizing MATLAB tool, by this technique computation becomes simple and requires less time when compared to other methods.
