Power-voltage-current meter, 3-phase dq0

Extends from Partials.Meter2Base (Meter 2 terminal base, 3-phase dq0).

Information

'Meters' are intended as diagnostic instruments. They allow displaying signals in alternative representations, both in SI-units or in 'pu'.
As they use time-dependent coordinate transforms, use them only when and where needed. Otherwise use 'Sensors'.

Output variables in the chosen reference system:

  p         {AC active, AC reactive, DC} power term_p to term_n
  v          voltage phase-to-ground dq0
  vpp        voltage phase-to-phase dq
  i          current dq0, term_p to term_n

Optional output variables:

  p_av       power term_p to term_n, time tau average of p
  v_abc      voltage phase-to-ground,  abc-inertial system
  vpp_abc    voltage phase-to-phase,   abc-inertial system
  i_abc      current term_p to term_n, abc-inertial system
  v_norm     norm(v)
  i_norm     norm(i)
  alpha_v    phase(v)
  alpha_i    phase(i)
  cos_phi    cos(alpha_v - alpha_i)

Comment on the sign-definition of reactive power see ACdq0.Sensors.
