【国外标准】 IEEE Recommended Practice for Fault Diagnosis and Protection in Smart Distribution System

This recommended practice focuses on the configurations and schemes of fault diagnosis and protection corresponding to different grid operation modes, control patterns, equipment conditions, and reliability requirements in smart distribution network. With the development of information and communication technology (ICT ), there is diverse and abundant data in monitoring and control systems for the distribution network. And due to the connection of distributed energy resources (DERs) and… read more electric vehicles, the distribution network becomes more diversified and complex. Considering different distribution network conditions and requirements, this recommended practice provides valuable practices relevant to the fault diagnosis and protection strategies including operation requirements, architecture of fault diagnosis and protection configuration, basic functions and technical indexes of software systems and hardware terminals, the realization modes of fault diagnosis and protection, relevant information exchange demand, and so forth. 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. This recommended practice applies to distribution systems from 6 kV to 20 kV. read less
