摘要
着重叙述了用MCS—51单片机实现6KV馈出线继电保护。系统地给出了本保护的硬件设置以及数学模型和软件流程。还介绍了系统同步跟踪采样硬件的构成。
This paper describes the basic method for realizing the relay protection with 8031 chip microcomputer in 6kv feed line. The hard—ware, mathematical model and soft ware of the protective system are listed. This paper also introduces the strueture of A·C Sampling hardware for the system synchronizing tracing.
