Rectifier - Power Flow Tab

When the rectifier type is thyristor, the control can be one of the following:

• Voltage: If the output is voltage controlled, specify the per unit control voltage in the Ctrl kV PU field.
• Current: If the output is current controlled, specify the output current in the Current Set Point field.

Commutation impedance is used to calculate the power flow using Kimbark’s equations. The rectifier must be fed by a dedicated transformer, where the characteristics are also defined here:

• Z1: Equivalent impedance in percent. Corresponds to the upstream rectifier transformer.
• X/R: X/R ratio of the upstream rectifier transformer.
• kVA: kVA rating base for Z1.

When the rectifier type is IGBT, this specifies the control input power factor.

Ratio of output power to input power in percent.

For IGBT type or voltage control thyristor type, this is the controlled output voltage in per unit.

The fixed value of output current in Amps for current controlled thyristor type.
