IEEE 1129 2014 Edition, March 27, 2014 Guide for Online Monitoring of Large Synchronous Generators (10 MVA and Above)
More info
Description / Abstract:
This document describes guidelines for online monitoring of
large synchronous generators with ratings of 10 MVA and above. The
scope includes generators with salient-pole rotors as well as
generators with cylindrical rotors.
This standard also provides basic information on the various online monitoring techniques described as well as recommended threshold values for initiating a remedial or compensating action, whenever those values are typical within the power generation industry.
This standard does not cover those instruments that are clearly associated with the protection scheme of the generator, such as: differential, out-of-step, over/under frequency, and so forth.
Purpose
The purpose of this guide is to
a) Describe mechanisms of degradation and applicable monitoring devices.
b) Describe methods available for online monitoring of large synchronous generators included within the scope of this standard.
c) Recommend which of the online monitoring techniques described in this standard ought to be adopted based on machine type.
d) Recommend monitored threshold values for initiating remedial or compensating actions when widely agreed industry practice exists.
