Formation of Zbus Martix By Using Step By Step Method For 8 Bus Power System

摘要

Power flow analysis is the backbone of power system analysis and design. They are necessary for planning, operation, economic scheduling and exchange of power between utilities. The principal information of power flow analysis is to find the magnitude and phase angle of voltage at each bus and the real and reactive power flowing in each transmission lines. Power flow analysis is an importance tool involving numerical analysis applied to a power system. In this analysis a general and procedural algorithm for- Y matrix building is proposed in this paper. We know that the procedure for obtaining Z bus matrices in any frame of reference. Requires Matrix Transformation Involving Inversion And Multiplications. It Could Be Very Laborious And Time Consuming Process For Large System Involving Hundreds Of Nodes Or Buses. Such an algorithm would be very con venient for various largesystemsthat may needed while the system is in operation such as addition of line, removal of lines and change in parameters. The bus impend ence matrix can be directly found by using building algorithm and analysis of large no of bus system can be done easily.Zbus by taking a casestudy of 110/33 KVVishrambag substation of 8bus by using tool MATLAB R2014a, version 8.3.0.532.by this method calculation is easy and required less time as compared to hand calculation.Hand calculation's time consuming as the no buses increases.
