IEEE C37.234 2009 Edition, September 11, 2009 Guide for Protective Relay Applications to Power System Buses
More info
Description / Abstract:
Concepts of power bus protection are discussed in this guide.
Consideration is given to availability and location of breakers,
current transformers (CTs), and disconnectors, as well as
bus-switching scenarios, and their impact on the selection and
application of bus protection. A number of bus protection schemes
are presented; their adequacy, complexity, strengths, and
limitations with respect to a variety of bus arrangements are
discussed; specific application guidelines are provided. Breaker
failure (BF) protection is discussed as pertaining to bus
protection. Means of securing bus protection schemes against
corrupted relay input signals are also included.
Purpose
The purpose of the guide is to assist utility engineers and industrial and commercial plant engineers in selecting and engineering proper bus protection.
