Abstract In order to solve the problems in current power grid operation safety management field, the paper firstly distinguishes the concept definitions and forms the uniform standards by discriminating the basic concepts in safety management field. Then, the extension model is formed through standardizing the relationship between different terms by using Wayne diagram based on the set theory. Finally, a set of concept identification algorithm flow is proposed to help the identification of concepts in actual practices. The research shows that, from the perspective of accident causation, the safety management concepts can be divided into two categories. In terms of the causation, the accident potential belongs to the hazard of second kind and third kind which is included into the risk; in the results caused by the causation, the accident precursor includes the near-miss and the accident without intervention which are included into the incident.
