Abstract

A redundancy design strategy based on component´s fault model of device was proposed for distributed control system (DCS). This paper analyzed component´s fault model of typical device based on the characteristic of DCS, sorted the faults of components according to the feature which is individual and diagnostic online between the faults of redundancy devices, and put forward the invalidation rate equation of the redundancy system. Then proposed a redundancy design method and verify method of reliability based on the analysis of component´s fault model in redundancy device. At last, the experiment data of field application were collected and these data have verified the conclusion above.
