Optimization measures to reduce the influence of the network failure in DCS system of power plant

In order to alleviate or avoid the adverse impact of the DCS system net fault on the unit running state, in this paper, the logical is combed and analyzed according to network failure mode and network signal fault characteristics, and the control logic and signals which influence the unit state are optimized. Through theoretical analysis and practical verification, the optimized logic can effectively alleviate the adverse impact of network faults on the unit state.
