[BPA] BPA Knowledge Summary

Calculation target: Calculate the node voltage and phase angle, and then calculate the line power.

The active and phase angles are closely related, and the reactive power and voltage are closely related.

The direction of active flow is always from the phase angle of large flow phase angle small.

The direction of reactive flow is always low by the high voltage flow voltage.

The presence of BPA currents is analyzed by low voltage to high voltage flow:

According to the above analysis, this is due to the low voltage to the phase angle is large, and the high voltage phase angle is small, so that the active power from the phase angle of large flow to the phase angle small nodes, resulting in low voltage flow to the high voltage. And the value of the active current is very large.

The generator absorbs reactive power analysis in BPA:

The electrical parameters of the circuit are set too large, resulting in the emergence of the generator absorption reactive power.

Correction method: Reduce the line electrical na parameters.
