Formation of Ybus Martix By Using Direct Inspection MethodFor “12”Bus Power System.
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 12
Abstract
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 Y bus or 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 convenient for various large system that may needed while the system is in operation such as addition of line, removal of lines and change in parameters. The bus impendence matrix can be directly found by using building algorithm and analysis of large no of bus system can be done easily.As compared to other methods of Ybus formation Direct inspection method is convenient we have mention algorithm to calculate Ybus by taking a casestudy of 440kv Talandge, India substation of 12 bus by using tool MATLAB R2010a,version 7.10.0.499 by this method calculation is easy and required less time as compared to hand calculation Hand calculationis time consuming as the no buses increases.
