Package com.powsybl.openloadflow.ac

Class VoltageMagnitudeInitializer

java.lang.Object

com.powsybl.openloadflow.ac.VoltageMagnitudeInitializer

All Implemented Interfaces:

VoltageInitializer

public class VoltageMagnitudeInitializer
extends Object
implements VoltageInitializer

This voltage initializer is able to find a voltage magnitude starting point by resolving a linear system using only voltage set points, branches reactance and branches voltage ratio. This initializer is particularly useful for cases with a large range of voltage (many transformers with a ratio far from 1pu for instance).
