Introduction
This block defines some of the parameters of voltage source converter (VSC) which can be adjusted during real time simulation. This block is usually put in the console subsystem and its output is connected to the input of the VSC Configuration Block. The VSC model can simulate a multi-stage multi-phase converter containing multiple two-level half-bridge (HF), full-bridge (FB) converters, three-level clamp double (CD), T-type (T-) and neutral point clamped (NPC) converters, and/or dual active bridges (DABs).
Mask and Parameters
| Name | Description | Unit | Variable = {Possible Values} | |
|---|---|---|---|---|
| SM type of group 1 | The VSC model simulate a multi-stage converter contains up to three groups converter units. The units in each group are of the same converter type. The supported types are Half-bridge, Full-bridge, Clamp double, T-type, and neutral point clamped. This parameter sets the type for the first group of converter units. | |||
| number of SM in group 1 | Defines the number of converter units in group 1 | |||
| SM type of group 2 | The VSC model simulate a multi-stage converter contains up to three groups converter units. The units in each group are of the same converter type. The supported types are Half-bridge, Full-bridge, Clamp double, T-type, and neutral point clamped. This parameter sets the type for the second group of converter units. | |||
| number of SM in group 2 | Defines the number of converter units in group 2 | |||
| SM type of group 3 | The VSC model simulate a multi-stage converter contains up to three groups converter units. The units in each group are of the same converter type. The supported types are Half-bridge, Full-bridge, Clamp double, T-type, and neutral point clamped. This parameter sets the type for the third group of converter units. | |||
| number of SM in group 3 | Defines the number of converter units in group 3 | |||
| IGBT/diode forward voltage | Defines the forward voltage | V | ||
| permanent Cap SC fault | Once checked, the capacitor is supposed to be damaged during short circuit fault and its voltage keeps 0. | |||
Note: The total number of SM of the three groups should be less than the parameter of "number of SM" set in VSC Configuration Block.
| Name | Description | Unit | Variable = {Possible Values} | |
|---|---|---|---|---|
| shunt resistance factor | User can change the capacitor discharge resistor value in the converter during real time simulation by adjust this parameter. The actual resistance value is the resistance value defined in VSC Configuration Block multiplied by this factor. | |||
| capacitance factor | User can change the capacitor value in the converter during real time simulation by adjust this parameter. The actual capacitance value is the capacitance value defined in VSC Configuration Block multiplied by the capacitance factor. | |||
| Vcap mode | normal operation: works as a capacitor Vcap reset to 0: the capacitor voltage is reset to 0 Vcap set to fixed value: the capacitor voltage is fixed | |||
| Vcap fix value (SI) | Define the capacitor voltage if "Vcap set to fixed value" in Vcap mode is selected | |||
| Name | Description | Unit | Variable = {Possible Values} | |
|---|---|---|---|---|
| DAB inductor factor | User can change the inductor value in the DAB circuits during real time simulation by adjust this parameter. The actual inductance value is the inductance value defined in VSC Configuration Block multiplied by this factor. | |||
| DAB resistor factor | User can change the series resistor value in the DAB circuits during real time simulation by adjust this parameter. The actual resistance value is the resistance value defined in VSC Configuration Block multiplied by this factor. | |||
