Phasor Dynamics

Root elements

Name	Value
`system_model_file`	Path to the system model file[1]
`dt_monitor`	Monitor output time interval for recorded simulation results (default: 0, no intermediate monitoring)
`tmax`	A floating-point value for max time
`rel_tol`	Relative solver tolerance (default: 1.0e-7)
`abs_tol`	Absolute solver tolerance override (default: 1.0e-9)
`dt_fixed`	Fixed solver time step size, or 0 for adaptive stepping (default: 0)
`events`	An array of event groups (see Events below)
`output_file`	Path to output (CSV) file (optional)
`reference_file`	A string containing the name of the case (optional)
`error_type`	One of { “relative” (default), “absolute” }
`error_tolerance`	A floating-point value for highest allowable total error (default: 1.0e-4)
`abs_err_threshold`	A floating-point value for the smallest value at which to scale relative error (default: machine epsilon for double-precision)

Each event group describes a system event that occurs at a given time point

Name	Value
`time`	A floating point value for time event occurs
`type`	Event type (one of { “fault_on”, “fault_off” })
`element_id`	An integer value referencing the element associated with the event (e.g., bus fault id)
