Abstract: In order to ensure the safe and stable operation of power grid and reduce production safety accidents, power supply companies carry out on-site safety management for a large number of infrastructure, production and operation operations, and have accumulated massive operational management and safety management business data. In order to make better use of these data and make it truly serve for early warning, prevention and control of operational risks of power supply enterprise, on the basis of combing the data of the entire process of field operations of power supply companies, the historical data of operational risk situation factors are analyzed to identify risk influencing factors such as human, machine, material, law, environment and management. The field operation risk assessment index system and operation safety situation index model are constructed from six dimensions including personnel, equipment (machinery), materials and appliances, operation methods, operation environment,  and time management. Combined with information technology, the tool design of intelligent risk situation assessment is carried out.
