A relevant example is provided in the attached project. Please refer to the attached pdf document for a description of the model aggregation principles.…
The injection of harmonic currents is modeled in PowerFactory using the "Harmonic Sources" object (class "TypHmcur"). Various PowerFactory elements can be configured as harmonic current sources, such…
The full network model might not be available for the harmonic analysis or the full model has to be reduced for performance reasons. Examples are: Harmonic Analysis for a power plant (e.g. wind farm /…
1. Lines: • Losses = P(terminal i) + P(terminal j) • Losses (no load) = U(terminal i)2* B1/2 + U(terminal j)2* B1/2 ,(B1 line susceptance C1,G1 . . . ) • Losses (load) = Losses - Losses(no load) 2.…

Firstly, it is considered a transformer that has a tap changer on the HV side, with a voltage source of 100 V on the HV. If the tap is on the position where the primary turns are np=50 then the…

The LDC is normally used in MV/LV radial networks to control the voltage at a remote end (by measuring the load current and compensating the voltage drop). A detailed explanation of the Line Drop…

To change the tap position of a 3-winding transformer during a simulation define a parameter event (EvtParam) using the appropriate variable: nntap_int_h which corresponds to the tap-position HV side.…

According to VDE/IEC in standard system fed directly from generators without transformer units, the corrected generator impedance defined in following equation has to be used. Z_GK = K_G x Z_G = K_G x…
