Problems solved by technology
However, since the power system is a large and complex system, it is difficult to obtain a complete knowledge base. When the power system structure and protection configuration change, the maintenance of the knowledge base is also quite difficult. These factors lead to the existing power fault diagnosis The method has low diagnostic efficiency and poor diagnostic effect

The embodiment of the invention discloses a power failure diagnosis method. The method comprises the following steps of: receiving an input power failure equipment node; according to the power failure equipment node, in a power grid topology model, acquiring power equipment nodes directly connected with the power failure equipment node; judging whether at least one of the acquired power equipment nodes is located in a power cut range, if so, diagnosing the power failure as a power-cut affected power failure; otherwise, diagnosing the power failure as an unknown failure, wherein the power cut range refers to a power grid topology containing preset power-cut power equipment nodes and nodes below the power-cut power equipment nodes in the power grid topology model. The embodiment of the invention also discloses a power failure diagnosis device. When the method and device disclosed by the embodiment of the invention are adopted for diagnosing power failures, the diagnosis efficiency can be increased, and the diagnosis effect can be improved.
Description
technical field [0001] The present application relates to the technical field of power systems, in particular to a power fault diagnosis method and a corresponding device. Background technique [0002] With the development and promotion of smart grid, the power supply level of my country's power system is increasing day by day, which better meets the power supply needs of various users. But at the same time, users have put forward higher and higher requirements on the reliability and speed of power supply. An important aspect of improving the reliability of power supply is to reduce the occurrence of power failures, and to quickly diagnose power failures (reasons) after power failures, so that timely repairs can restore the normal operation of the power grid as soon as possible. The power failure here can refer to factors such as equipment failure, power outage failure, and risk failure that lead to abnormalities in the power grid. [0003] At present, the methods of power...
