微机发电机转子接地保护装置的原理与设计

Principle and design of micro-processor generator rotor earth-fault protection equipment

叙述了微机发电机转子接地保护装置的基本原理、软硬件设计.本装置以高速高性能微处理机及实时多任务操作系统为基本开发手段,利用切换采样原理构成机组励磁回路一点和两点接地保护,测定转子接地故障点位置和过渡电阻的大小.

The paper introduces the principal theory and software and hardware design of microprocessor rotor earthfault protection equipment. The equipment has development environment with switch sampling theory to measure the earthfault location and transition resistance and can finish one location and twolocation earthfault protection in the excitation circuit of generator.
