power_flicker

Perform statistical analysis of instantaneous flicker level signal

Syntax

power_flicker

Description

power_flicker opens a tool that computes the short-term flicker severity (Pst) and long-term flicker severity (Plt) and displays the cumulative probability function (CPF) of an instantaneous flicker level signal (S5 signal).

Note

You must have a Control System Toolbox™ license to use the power_flicker function.

Dialog Box

Load

Load the S5 signal into the module. Choose between From file and From workspace. The default value is From workspace.

Start time (s)

Specify the time, in seconds, of the beginning of the observed period. The default value is 0.

Number of classes

Specify the number of classes, which are used by the tool to compute the cumulative probability function of the instantaneous flicker level. The default value is 256.

Pit observation intervals (nb of 10–min intervals)

Specify the number of 10-minute intervals used by the tool to measure the long-term flicker severity (Plt). The default value is 1.

Compute

Compute the percentiles P0.1s, P1s, P3s, P10s, and P50s, which are the flicker levels exceeded for 0.1%, 1%, 3%, 10%, and 50% of the time during the observed period. Computes the short-term flicker severity (Pst) and long-term flicker severity (Plt) and displays the cumulative probability function (CPF) of the S5 signal.

Introduced in R2015b
