Automatic faulty background studying and judging method based on marketing and distribution data run-through

The invention discloses an automatic faulty background studying and judging method based on marketing and distribution data run-through. According to the automatic fault repair faulty background studying and judging method, analysis is made based on a marketing and distribution information fused basic data model to obtain a topology from users to a power supply line, and a repair-class fault real-time location method based on repair fault information is adopted to locate possible fault sources in real time with the marketing and distribution information fused basic data model as the basis, the fault repair information as the reference and relevant medium-voltage fault power outage of a distribution network as the foundation. By analyzing the operation state of power supply equipment at a fault repair point, a repair-class fault can be quickly diagnosed. There is no need to spend a lot of energy in building an expert experience library. Studying and judging are quick and efficient. The method is highly versatile, and flexible and diverse. When the structure and the protection configuration of the power system change, the method can quickly adapt to a new power grid topology model.
