In order to better guarantee the operation effect of substation, a substation telecontrol fast point-to-point system based on Naive Bayesian algorithm is designed. The hardware structure configuration of the system is designed, the system software function is improved, and the fast point-to-point steps of substation telecontrol are simplified. And the experiment proves that the performance of the substation telecontrol fast point-to-point system based on Naive Bayesian algorithm is significantly improved, which can better ensure the operation safety of the substation.
