基于DSP的数字式断路器失灵保护

Digital circuit breaker failure protection based on DSP

断路器失灵保护要从母线保护中分离出来成为一个独立保护,而原来的母线保护虽能实现失灵保护的要求,但成本过高。针对此提出开发一套全新的以DSP为核心的数字式断路器失灵保护,主、从CPU板的软、硬件均采用模块化设计。经实践证明使用此保护可大大降低成本且具有高抗干扰性、高可靠性、低出错等优点。

Bus circuit breaker failure protection should be separated from bus protection,because it is too expensive to use the later to realize failure protection. A digital circuit breaker failure protection with DSP as its core is presented. Both hardware and software of main and slave CPU boards adopt modularized design. Practices show that it reduces cost and has higher anti-interference ability,reliability and lower error possibility.
