Basic space phasor models

This package contains basic space phasor models.

Real and imaginary part of voltage space phasor are the potentials v_[2] of the space phasor connector; (implicit grounded).

Real and imaginary part of current space phasor are the currents i_[2] at the space phasor connector;
a ground has to be used where necessary for currents flowing back.

`SpacePhasor` | Physical transformation: three phase <-> space phasors |

Physical transformation: three phase <-> space phasors

Physical transformation of voltages and currents: three phases <-> space phasors:

x[k] = X0 + {cos(-(k - 1)/m*2*pi),-sin(-(k - 1)/m*2*pi)}*X[Re,Im]

and vice versa:

X0 = sum(x[k])/m

X[Re,Im] = sum(2/m*{cos((k - 1)/m*2*pi),sin((k - 1)/m*2*pi)}*x[k])

were x designates three phase values, X[Re,Im] designates the space phasor and X0 designates the zero sequence system.

*Physical transformation* means that both voltages and currents are transformed in both directions.

Zero-sequence voltage and current are present at pin zero. An additional zero-sequence impedance could be connected between pin zero and pin ground.
