Assessment on the Threat to the Information Security of Power Plant Control System Based on SA-PSO-AHP Method

doi:10.11930/j.issn.1004-9649.201903085

Abstract

Abstract: Due to the severe situation of information security in power plant control system, based on the information security evaluation of a power plant, a hierarchical progressive analysis model is established by using analytic hierarchy process (AHP) model. And then the consistency problem of judgment matrix is solved through the enhancement of particle swarm optimization (PSO) method in combination with simulated annealing (SA) algorithm, which can effectively overcome the drawbacks such as strong subjectivity and uncertainties in the current information security threat assessment. The practice in the thermal plant shows that this method can not only fully demonstrate the application of the fuzziness of the evaluation elements and processes, but also reduce the impact of individual subjective factors such that satisfactory evaluation results can be achieved.

Key words: control system of thermal power plant, analytic hierarchy process, simulated annealing, particle swarm optimization, consistency correction, threat assessment
