Multiple-Run
The multiple-run component is available to users for the purpose of performing parametric studies. Through selection of appropriate parameter and input settings, the user can adjust the number of simulations that will be executed (number of simulation runs). The output variable signals from this component can be used as input signals to other components.
The inputs and outputs of this component are:
- Meas-Enab: Used to enable (1) or disable (0) the channel recording. Recording will be active only when the input to this variable is 1. Thus, the user can select the time interval(s), over which the input data will be considered for processing and recording.
- Ch. 1 ... Ch. 6: Input signals to be recorded.
- V1, V2 ... V6: Output signals controlled by the component.
Some application examples are as follows:
- Changing the point on wave (POW) of a fault inception, in order to find the worst overvoltage and/or peak fault current.
- Modifying the gains of a controller, in order to find the best response following a disturbance.
- Stepping through a range of RLC or system parameters to determine an optimum.
- Changing the type and location of faults, as well as the POW, in order to find worst case voltage and current transients.
- POW switching of a transmission line or cable, in order to determine the worst case transient overvoltage levels at different locations along the line.
The output signal values (any given output signal is constant for a given simulation run) can be used as inputs to either constant or variable-type parameters or connection ports on any other component. Depending on the requirements, the user can select to output up to six signals (V1 to V6). However, only one of the output signal values can changed between two successive simulation runs.
