The elements of the Admittance Matrix are the trans-admittance parameters YAdmittance Matrix (Ybus ) Formation. The program computes the admittance matrix by considering the transmission lines (pi model) data, transformers settings, and shunt elements. This program finds the Ybus matrix of a power system, the folder has 4 test cases (the 5, 6, 9 and 14 ieee bus systems), the data of the test cases is given on the per ...Admittance. In electrical engineering, admittance is a measure of how easily a circuit or device will allow a current to flow. It is defined as the reciprocal of impedance, analogous to how conductance and resistance are defined. The SI unit of admittance is the siemens (symbol S); the older, synonymous unit is mho, and its symbol is ℧ (an ...How do we characterize multi-port device? A: The analogy to Z, Y, and Γ for a multi-port device is the impedance matrix, the admittance matrix and the scattering matrix. HO: THE IMPEDANCE MATRIX HO: THE ADMITTANCE MATRIX We can determine many thing about a device by simply looking at the elements of the impedance and scattering matrix.
