ABSTRACT
Z-bus a matrix which contains the impedance of each element in an electric power system.
z-parameters the input and output impedances that are used to characterize a two port device (network).
z-transform a mathematical transformation that can be applied to a differential equation of a system in order to obtain the system’s transfer function. The z-transform is defined as
Z {f (n)} = F(Z) = ∞∑ n=0
f (n)z−n
where n is the series of discrete samples, f (n) is the series of sample values corresponding to the discrete samples.
