Objective To write a simple program in MATLAB174。 for the algorithm of bus admittance matrix. 2. System Requirement Computer with MATLAB174。 6 or above installed. 3. Procedure Launch the MATLAB program. Go to FILE NEW Mfile. Write a function Y = The_Node_Admittance_Matrix(TopoStructureAndBranchPara) for the formation of the bus admittance matrix. 1 TopoStructureAndBranchPara is the transmission line, cable and transformer input data and contains five columns parameters. The first two columns are the line bus numbers and the remaining columns contain the line resistance and reactance in perunit and transformer tap ratio or capacitor of transmission line. The function should return the bus admittance matrix. 4. Exercises Use the written function, Y = The_Node_Admittance_Matrix (TopoStructureAndBranchPara) to obtain the Ybus of the following power system work: Q1. You are required to write the Ybus topological structure and parameter into a text file. (Hint: use the matlab text piler to write down the table 1 data, using the ma to separate the parameters, and save it use the name of ) Q2. You are required to write out the program flow figure of forming a nodal admittance matrix.Hint. You are required to pile a program to form the Ybus Matrix, the following program is a reference program to you.
