OpenIPSL.Electrical.Solar.PowerFactory.General.Picdro

Pick-up drop-off implementation for protection functions

Information

This function implements a logical pick-up-drop-off function commonly used when designingprotection schemes (e.g. fault detection, signal out-of-range, etc.).

Parameters

OpenIPSL.Electrical.Solar.PowerFactory.General.StaVmea

Voltage Measurement Device

Information

StaVmea model in PowerFactory measures voltage and frequency. The frequency in PowerFactory is computed with respect to the frame rotating with frequency equal to the synchronous machine. This is supported via the input omega here. Most of the OpenIPSL examples do not provide omega of the reference machine and thus, if the input is not connected the frequency is computed with respect to the 50 Hz reference frame and filtered to simulate the measurement delay.

Parameters

Name	Description
Tfe	Measurement delay [s]
fn	Nominal frequency [Hz]
angle_0	Initial angle [rad]
use_ref_machine_frequency	Use reference machine frequency

Connectors

Name	Description
p
u	Voltage magnitude [pu]
fe	Electrical frequency [Hz]
omega	Reference machine frequency [Hz]
