Information

This is a partial model that is extended by all the other validation test cases. This model defined replaceable probes and transformer so they can be easily changed when implementing the different tests.

More information can be found in each model that extends this one.

Reference results

The reference results for the tests are saved as parameter of the model and compared to the simulated ones. The error between the results (herein called X_model) and the references (herein called X_ref) are computed in both absolute and relative way. Note that X_model and X_ref can be either voltage amplitudes or phase angles.

Err_abs = X_model - X_ref

Err_% = Err_abs / X_ref

The variables that store the results of the comparison are listed in the table below

Variable	Description	Unit
`err_V2[3]`	Error between simulated voltage at node 2 and reference results	[V]
`err_V3[3]`	Error between simulated voltage at node 3 and reference results	[V]
`err_V4[3]`	Error between simulated voltage at node 4 and reference results	[V]
`err_Theta2[3]`	Error between simulated phase angle at node 2 and reference phase angle	[rad], displayed as [deg]
`err_Theta3[3]`	Error between simulated phase angle at node 2 and reference phase angle	[rad], displayed as [deg]
`err_Theta4[3]`	Error between simulated phase angle at node 2 and reference phase angle	[rad], displayed as [deg]
`err_V2_percent[3]`	Relative error between simulated voltage at node 2 and reference results	[%]
`err_V3_percent[3]`	Relative error between simulated voltage at node 3 and reference results	[%]
`err_V4_percent[3]`	Relative error between simulated voltage at node 4 and reference results	[%]
`err_Theta2_percent[3]`	Relative error between simulated phase angle at node 2 and reference phase angle	[%]
`err_Theta3_percent[3]`	Relative error between simulated phase angle at node 2 and reference phase angle	[%]
`err_Theta4_percent[3]`	Relative error between simulated phase angle at node 2 and reference phase angle	[%]
