IEEE Guide for Protective Relay Applications to Power System Buses
Also Known As: IEEE Std C37.234-2021
The IEEE C37.234-2021 standard provides guidance on the application of protective relays to power system buses. The standard discusses principles of power bus protection, addressing the availability and location of breakers, current sensing devices, and disconnect switches. It also covers various bus configurations and switching schemes and their impact on the selection and application of bus protection.
The guide presents different bus protection schemes and examines their characteristics, strengths, and limitations. It provides specific application guidelines for the selection and engineering of bus protection schemes based on various bus arrangements. The standard also discusses breaker failure (BF) protection as it relates to bus protection and includes measures to secure bus protection schemes against corrupted relay input signals.
The primary purpose of this standard is to assist utility engineers, as well as industrial and commercial plant engineers, in selecting and engineering appropriate bus protection schemes. It serves as a comprehensive resource for understanding bus protection concepts and implementing reliable and effective bus protection in power systems.
