| Abstract: | The transient, intermittent and permanent faults may happen because of the influence of the external condition or the internal devices when the components work in the distributed system. In order to process the fault, the importance is to identify the serious fault.According to the fault feature, frequency and the degree of seriousness,set the gain, the drain and the threshold in the filter algorithm of gain/drain.It filtered the fault flexibly and ensured the system to work reliably and stably. |

| Keywords: | fault filter up and down count gain drain |
