Bus admittance
WebBUS ADMITTANCE AND BUS IMPEDANCE MATRICES Let’s first review the Per-Unit (pu) System actual quantity Quantity in pu = base value of quantity For example S V I S pu = Vpu = I pu = SB VB IB Z Z pu = ZB Usually line-to-line voltage VB and MVA SB are selected. Then VB SB 3 IB = ZB = 3VB IB substitute (VB ) 2 (kVB ) 2 ZB = = SB MVAB Change of … WebAdmittance matrix is used to analyze the data that is needed in the load or a power flow study of the buses. It explains the admittance and the topology of the network. In a y-bus matrix, The diagonal element Y ii is the sum of all the admittances of the elements connected to the i th bus. Y ii = Σ y ik , k = 1, 2, …n and k ≠ i
