Method and system for automatic recognition of fault signal of power grid and plan correlation

Abstract

The invention relates to a method and system for the automatic recognition of a fault signal of a power grid and the plan correlation. The method comprises the following steps: S101, building a signalmatching rule base, carrying out the dividing of a fault type according to different electrical devices, ad building a signal matching rule for each fault type; S102, building a plan system, and inputting a fault plan in the power grid into the system; S103, automatically recognizing the fault type and position of a fault signal through the signal matching rule, and achieving the automatic correlation with the fault plan. The method can help a power grid scheduling monitoring worker determine a defect and an accident signal of the power grid quickly and accurately. Moreover, the method and system achieve the automatic correlation of the defects of specific equipment with an accident plan, achieve the correlation between the signal recognition and a processing plan, greatly reduces the workload and wrong judgment of the power grid scheduling monitoring worker and the processing capability of signals, improves the signal recognition and processing efficiency and accuracy, and facilitates the safe and stable operation of the power grid.

Description

technical field [0001] The invention belongs to the technical field of power system grid monitoring and operation control, and more specifically relates to a method and system for automatic identification and associated pre-plan of grid fault signals. Background technique [0002] The SOE signal on the EMS system is mainly a series of event sequence records related to the real-time remote signaling, telemetry or protection actions of the power grid. With the continuous expansion of the grid scale, grid dispatching and monitoring personnel are faced with more and more SOE signals, and the workload and pressure are also increasing. Especially in the face of emergency defect signals or accident signals, grid dispatching and monitoring personnel are required to identify the signals as soon as possible and deal with them in accordance with relevant regulations and emergency plans, so that timely measures can be taken to isolate faults and ensure the safe and stable operation of t...

AI Technical Summary

Problems solved by technology

However, the above literature only realizes the judgment of the power grid accident signal, does not involve the defect signal, and also lacks effective correlation with the plan, so it cannot provide further processing opinions

[0004] In the current grid monitoring mode, facing a large number of SOE signals, especially grid accident signals, it is difficult for grid dispatching and monitoring personnel to quickly identify signals

After confirming the nature of the signal, it is necessary to search for relevant regulations and plans for processing, and the plans are generally stored in computers or filing cabinets in the form of electronic documents or paper, and it is not only urgent to consult them when dealing with defects or power grid accidents urgently , and it is easy to cause misuse of the plan

In short, from signal recognition to processing, there is still a lack of effective intelligent association means, which is inefficient
