Web5Shunt Admittance of Overhead and Underground Lines. The shunt admittance of a line consists of the conductance and the capacitive susceptance. The conductance is usually ignored because it is very small compared to the capacitive susceptance. The capacitance of a line is the result of the potential difference between conductors. WebNov 14, 2024 · In contingency analysis, the shunt elements are neglected, while forming the Z-bus matrix, which is used to compute the outage distribution factors. This can be easily obtained by inverting the Y-bus matrix formed by inspection method or by analytical method. The impedance matrix is a full matrix and is most useful for short circuit studies.
WebFor the admittance matrix, the T model is transformed into a PI model with the wye-delta transformation. For a transformer with tap ratio \(\tau\) on the primary side tap_side = 0 and phase shift \(\theta_{\textrm{shift}}\), the equivalent PI model is given by: for which the currents and voltages are related by:
