Power, 1-ph

The Power, 1-ph component computes the active power (P), in watts, and the reactive power (Q), in vars, of a voltage-current pair at the specified fundamental frequency.

The output is held constant to the specified Initial active power and Initial reactive power values for one cycle of the specified fundamental frequency.

Example model

This example demonstrates the usage of 1-phase power block. A 1-phase 240V, 60Hz source connected to a 3kW and 0.6kVar load is demonstrated.

Note that the following demo requires that users edit the ScopeView template, and replace the existing .oprec data source with the data generated during the simulation.
