Class Description

DC side of the voltage source converter (VSC).

Attributes

Name Type Description
delta AngleDegrees Angle between VsConverter.uv and ACDCConverter.uc. It is converter’s state variable used in power flow. The attribute shall be a positive value or zero.
droop PU Droop constant. The pu value is obtained as D [kV/MW] x Sb / Ubdc. The attribute shall be a positive value.
droopCompensation Resistance Compensation constant. Used to compensate for voltage drop when controlling voltage at a distant bus. The attribute shall be a positive value.
maxModulationIndex Float The maximum quotient between the AC converter voltage (Uc) and DC voltage (Ud). A factor typically less than 1. It is converter’s configuration data used in power flow.
maxValveCurrent CurrentFlow The maximum current through a valve. It is converter’s configuration data.
pPccControl VsPpccControlKind Kind of control of real power and/or DC voltage.
qPccControl VsQpccControlKind Kind of reactive power control.
qShare PerCent Reactive power sharing factor among parallel converters on Uac control. The attribute shall be a positive value or zero.
targetPhasePcc AngleDegrees Phase target at AC side, at point of common coupling. The attribute shall be a positive value.
targetPowerFactorPcc Float Power factor target at the AC side, at point of common coupling. The attribute shall be a positive value.
targetPWMfactor Float Magnitude of pulse-modulation factor. The attribute shall be a positive value.
targetQpcc ReactivePower Reactive power injection target in AC grid, at point of common coupling. Load sign convention is used, i.e. positive sign means flow out from a node.
targetUpcc Voltage Voltage target in AC grid, at point of common coupling. The attribute shall be a positive value.
uv Voltage Line-to-line voltage on the valve side of the converter transformer. It is converter’s state variable, result from power flow. The attribute shall be a positive value.
