ETAP PowerStation Sequence of Operations
ETAP PowerStation Sequence of Operations
(OP)
All right everyone, here's a pretty focused question. Has anyone out there had much experience with the new Sequence of Operations module in ETAP PowerStation? This module is supposed to allow you to simulate a fault (3-phase or line-to-ground) anywhere in a system model and it will evaluate and report device clearing times in sequence. I played with it a bit when it first came out, but I wanted to see if anyone else has any experience with it - good or bad. My experience with it was not real positive, but the system I tried it on had a very complicated protection scheme. I am getting ready to analyze a loop system and I am trying to decide if I should try ETAP's Sequence of Operations or not.

It's a nice idea and moves into the realm of fault simulation. But it's important to be able to verify the results somehow.
Seems like it could be helpful for a looped system - it's difficult to use TCCs to evaluate and display results for loops since the relays often see very different of fault current for any one fault.
