- Zbus
Z Matrix or "bus impedance matrix" is an important tool in power system analysis. Though, it is not frequently used in
power flow study , unlikeYbus matrix , it is, however, an important tool in other power system studies likeshort circuit analysis orfault study .Context
Electric power transmission needs optimization. Only
Computer simulation allows the complex handling required. The "Zbus" matrix is a tool in that domain.Formulation
Z Matrix can be formed by either inverting the
Ybus matrix or by usingZ bus building algorithm . The latter method is harder to implement but more practical and faster ("in terms of computer run time and number of floating-point operations per second") for a relatively large system.External links
