The traditional operation and maintenance decision algorithms often ignore the analysis of data source security, which makes them highly susceptible to noise, time-consuming in execution, and lacking in rationality. In this paper, we design an automated operation and maintenance decision algorithm based on data source security analysis. A multi-angle learning algorithm is adopted to establish a noise data model, introduce relaxation variables, and compare sharing factors with noise data characteristics to determine whether the data source is secure. Taking the ideal power shortage and minimum maintenance cost as the objective function, we construct a classical particle swarm optimization model and derive the expressions for particle search velocity and position. To address the problem of local optima, a niche mechanism is incorporated: the obtained automated data is treated as the population, the reasonable number of iterations is determined, the individual fitness is stored, and the optimal state is obtained through a continuous iterative update strategy. Experimental results show that the proposed strategy can shorten operation and maintenance time, enhance the rationality of decision-making, improve algorithm convergence, and avoid falling into local optima. In addition, fault-tolerant analysis is performed on the security of the data source, effectively eliminating bad data, preventing interference from malicious data, and further improving convergence performance.
