Description

The Busbar (DC) block is a DC connector for load-flow analysis. You can use this block with Simscape™ Electrical™ DC networks that are configured to run in time or frequency-time simulation mode. You can view the voltage and power values by enabling simulation data logging or by exposing the optional measurement ports on the block. For more information about data logging, see About Simscape Data Logging.

Parameters

Number of connections — Number of port connections

2 (default) | 1 | 3 | 4

Number of port connections to expose on the block.

Rated DC voltage — Busbar rated DC voltage

1e3 V (default) | positive scalar

Rated DC voltage of the busbar. This block uses this value to scale the per-unit voltage value.

Measurement type — Measurement type

Instantaneous (default) | Average over a specified period

Type of measurement. In time simulation mode, you can set this parameter to either Instantaneous or Average over a specified period. In frequency-time simulation mode, you must set this parameter to Instantaneous.

Averaging period — Averaging period of measurement

1e-2 s (default) | positive scalar

Period over which the voltage and power values are averaged.

Dependencies

To enable this parameter, set Measurement type to Average over a specified period.

Measurement ports — Measurement port exposure

No (default) | Yes

Whether to expose the Vt and P physical signal output measurement ports.
