Description

The Three-Phase Mutual Inductance Z1-Z0 block implements a three-phase balanced inductive and resistive impedance with mutual coupling between phases. This block performs the same function as the three-winding Mutual Inductance block. For three-phase balanced power systems, it provides a more convenient way of entering system parameters in terms of positive- and zero-sequence resistances and inductances than the self- and mutual resistances and inductances.

Parameters

Positive-sequence parameters

The positive-sequence resistance R1, in ohms (Ω), and the positive-sequence inductance L1, in henries (H). Default is [ 2 50e-3].

Zero-sequence parameters

The zero-sequence resistance R0, in ohms (Ω), and the zero-sequence inductance L0, in henries (H). Default is [4 100e-3].
