A fault location method and device for a power grid automation dispatching system

Abstract

The invention discloses a fault locating method and apparatus of a power grid automatic dispatching system. The fault locating method of a power grid automatic dispatching system includes the steps: receiving fault alarm information, and determining a plurality of alarmed processes according to the fault alarm information; according a service logic mapping relation, determining the alarmed processhaving the earliest time sequence when the alarmed process is executed in the same service as a candidate fault source process; according to a resource occupation constraint relation, determining theresource occupation type of the candidate fault source process, and acquiring the rated working parameter of the resource occupation type corresponding to the candidate fault source process; and acquiring the current working parameter of the candidate fault source process, and if the current working parameter exceeds the rated working parameter, determining that the candidate fault source processis a fault source process. The fault locating method and apparatus of a power grid automatic dispatching system can determine the candidate fault source process in the service through the service logic mapping relation, can decouple the complex automatic dispatching system through the resource occupation constraint relation and locate the fault source process, and can realize efficient and accurate fault location.

Description

technical field [0001] The invention relates to the technical field of smart grid fault diagnosis, in particular to a fault location method and device for a grid automatic dispatching system. Background technique [0002] With the development of society and economy and the advancement of technology, the smart grid (hereinafter referred to as the grid) has become the development direction of the future grid. The application of the power grid promotes the development and utilization of clean energy, optimizes the energy structure, promotes innovation in related fields, and improves the living standards of the people. The safe and stable operation of the power grid has far-reaching significance. The safe operation of the power grid requires high requirements, and the failure time of the power grid is not more than 3 minutes a year. After years of development, the power generation, transmission, transformation and distribution networks of the power grid have high reliability, ...

Problems solved by technology

At present, the monitoring function of the automatic dispatching system mainly relies on the electronic duty alarm, and other application modules also have some monitoring functions, but the monitoring range is small, the content is simple, the function is independent, and the false alarm rate is high, which is difficult to meet the needs of the smart grid.
