Zbus
From Wikipedia, the free encyclopedia
Z Matrix or bus impedance matrix is an important tool in power system analysis. Though, it is not frequently used in power flow study, unlike Ybus matrix, it is, however, an important tool in other power system studies like short circuit analysis or fault study.
[edit] Context
Electric power transmission needs optimization. Only Computer simulation allows the complex handling required. The Zbus matrix is a tool in that domain.
[edit] Formulation
Z Matrix can be formed by either inverting the Ybus matrix or by using Z 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.
