Power failure fault judgment method based on line topological relation

Abstract

The invention discloses a power failure fault judgment method based on a line topological relation, belongs to the technical field of power failure fault judgment based on the line topological relation and aims to improve the power failure fault judgment method based on the line topological relation. The technical scheme adopted for solving the technical problem is as follows: establishing a multi-source information fault line judgment system; establishing a power failure event information pool: after a to-be-judged power failure event is triggered, the specific control system sends event information to the information pool recorded by the power failure event database server through the monitoring server, and establishing a task of a to-be-judged power failure fault; and after the task is established, carrying out power failure fault judgment and analysis according to a trigger condition and an external interface, feeding back power failure information to a fault analysis server by a specific control system, and enabling the fault analysis server to generate a power failure fault judgment and analysis result and send the result to an information pool of a database server to perfect power failure event information. The method is applied to power grid power failure fault judgment places.

Description

technical field [0001] The invention discloses a method for judging a power outage fault based on a line topological relationship, and belongs to the technical field of power outage fault judgment based on a line topological relationship. Background technique [0002] During the dispatching and operation of the power grid, there are often hidden dangers in the line. If the hidden danger is not repaired for a long time, it will turn into a line fault. It is very important; the current location methods for hidden faults in the power grid mainly include traveling wave method, impedance-based fault location, voltage drop-based method, knowledge-based method, information integration method, etc. [0003] Since different business departments in the distribution network have developed numerous business application systems according to their own needs, each application system provides information about power failures from different perspectives. For example, customers report faults...

Problems solved by technology

For example, customers report faults and repairs through the customer service management system, and describe the outage faults found on the customer side; the distribution automation system and dispatching automation system model the topology of the distribution network and the main network topology, and obtain information from the data collection and monitoring system About the status of the outlet switch and branch line switch on the feeder, and related voltage and current information; the user information collection system is used to maintain the relationship between the meter and the customer, as well as the status and data of the meter and the meter box; the production management system is It can provide planned power outage information and equipment asset information in the distribution network; since the control systems of each department and user end are set independently, data interaction cannot be performed with each other, and information fusion cannot be performed when comprehensively analyzing the power grid. Reduce the accuracy and speed of fault judgment, resulting in low troubleshooting efficiency and long waiting time for power restoration, seriously affecting the service quality of power supply companies
