Vary parameters, start simulation and export scope waveforms by script

Description:
This script is a simple example to learn how to script.
The script is started from the EMTP design by double clicking on the 'Script1' grey button.
The script example:
... see more - varies a fault resistance
- runs a simulation for each value
- exports results of a selected list of scope in MAT and ASCII formats
- returns Min and Max

Continuous-Wavelet Transform for Fault Location in Distribution Power Networks: Definition of Mother Wavelets Inferred From Fault Originated Transients

Description:
The paper presents a fault location procedure for distribution networks based on the wavelet analysis of the fault-generated traveling waves. In particular, the proposed procedure implements the conti... see morenuous wavelet analysis applied to the voltage waveforms recorded during the fault in correspondence of a network bus. In order to improve the wavelet analysis, an algorithm is proposed to build specific mother wavelets inferred from the fault-originated transient waveforms. The performance of the proposed algorithm are analyzed for the case of the IEEE 34-bus test distribution network and compared with those achieved by using the more traditional Morlet mother wavelet.
