modelPVImeter
Power-voltage-current meter, 3-phase abc
Extends from Partials.Meter2Base (Meter 2 terminal base, 3-phase abc).
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 dqo
vpp voltage phase-to-phase dq
i current dqo, term_p to term_n
Optional output variables:
p_av power term_p to term_n, time 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 ACdqo.Sensors.
