IEEE Recommended Practice for Fault Diagnosis and Protection in Smart Distribution System

The fault diagnosis and protection schemes and application cases for smart distribution systems from ac 6 kV to 20 kV are provided by this recommended practice, covering security requirements, architectures, and configuration, as well as basic functions and technical indexes of software systems and hardware terminals and requirements of information exchange. Schemes provided in this document are adaptable to various operation modes, control patterns, equipment conditions, and reliability requirements of distribution systems. This recommended practice is mainly based on engineering practices in the voltage range of 6 kV to 20 kV. The proposed fault location, isolation, and service restoration (FLISR) schemes can also be used in the voltage range of 2.4 kV to 38 kV as specified in ANSI C84.1 after an evaluation of communication conditions and cost analysis. Phase (three-phase and phase-to-phase) faults, ground (three-phase-to-ground, two-phase-to-ground, and single-phase-to-ground) faults and conductor-broken faults are covered by the fault types. Changes and needs brought by the connection of distributed generators are considered, and schemes empowered by information and communication technologies are also introduced.

Other Activities From This Working Group

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.


No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.


No Inactive-Reserved Standards
