摘　　要：数字高压断路器具有无磨损、精度高、寿命长等优点,但某些部件的失效也会给电力系统及用户带来重大损失。为了提高断路器的性能和可靠性,减少事故,采用两片DSP芯片进行冗余来实现断路器控制器,不仅可以实现负载分担,还具有容错功能,在两芯片都正常工作的情况下,各自处理自己的输入信号,当其中某一芯片出现故障而不能处理信号时,另一芯片独立承担全部处理任务,提高了系统的处理能力和可靠性。Digital high voltage breaker has the advantages of no abrasion, high precision and long life-span, but the invalidation of some part of it will reduce the reliability of the whole system,Use two DSP chips to design breaker controller to improve the performance and reliability and to reduce accident based on redundancy. This design can share the load and also has the function of redundancy, when two chips work normally, they process their inputs separately, but when one of them runs out of order, the other will process all input information.
