Rule base construction method of section out of limit disposal strategy for thermal power unit equipment fault

This paper proposes a rule base construction method of section out of limit disposal strategy for thermal power unit equipment fault, which can solve the problems of abnormal power transmission and grid real-time scheduling caused by section out of limit. Through the improved Apriori algorithm, the section out of limit disposal strategy of thermal power unit equipment fault is designed. In the mining result of thermal power unit equipment fault section out of limit, the association rules between section state and unit and load disposal strategy are established. By using the improved Apriori algorithm, the policy data and section state data are set as the preceding and following constraints of the association rules, The strong association rules are obtained, and the rule base of cross section out of limit disposal strategy is constructed according to the association rules. The experimental results show that: the number of association rules obtained by the improved Apriori algorithm mining each database is less than 1000, and the rule effectiveness and analysis efficiency are significantly improved; The rule base built by this method can effectively deal with the out of limit problems of different sections and units, and the sensitivity of each generator node increases greatly after the treatment.
