Description

New IEEE Standard – Active – Draft. This recommended practice provides the fault diagnosis and protection schemes and application cases for smart distribution systems from AC 6 kV to 20 kV, 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 grid 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-20 kV. The proposed FLISR schemes can also be used in the voltage range of 2.4 kV – 38 kV as specified in ANSI C84.1 after an evaluation of communication conditions and cost analysis. The fault types cover 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.Changes and needs brought by the connection of distributed generators are considered. And schemes empowered by information and communication technologies are also introduced.
