An auxiliary decision-making method for power grid dispatching fault handling

Abstract

An auxiliary decision-making method for power grid dispatching fault processing, including: fault diagnosis: constructing a regional power grid topology map, establishing a power grid fault information association table for storing the correlation between a fault occurrence and corresponding fault information; screening OPEN3000 corresponding fault information when a fault occurs The characteristic information of the target component is searched for the fault of the target component and the corresponding fault caused by it, the degree of coincidence between the characteristic information and the corresponding fault is calculated, and the degree of coincidence is converted into the first probability of occurrence of each fault; the characteristic information includes when the fault occurs The fault messages, photon information, telemetry changes, and remote signal displacements; retrieve the data of the fault recording device when a fault occurs, use the wavelet analysis method to analyze the waveform, and combine the fault analysis results obtained from the recording report to calculate the occurrence of each fault. The second probability of failure; weight the first probability and second probability of failure, determine the scope and type of failure according to the principle of the highest probability, and then form a failure treatment plan based on this.

Description

technical field [0001] The invention relates to the field of power grid operation, in particular to an auxiliary decision-making method for power grid scheduling fault processing. Background technique [0002] At present, the power grid dispatching automation integration system (OPEN3000) can only display alarm and abnormal information, without functions such as signal analysis, fault judgment, and auxiliary decision-making. The information submitted to the dispatcher in the event of a fault is often some listed data and simple prompts. There is no comprehensive analysis and systematic judgment on the overall relevant alarm data, and there is a lack of decision support for power grid dispatching. When a power grid fault occurs, the system can transmit a large number of accident messages in time, but it cannot analyze and judge the fault itself, and cannot directly prompt the fault situation from the system. Fault diagnosis and fault treatment rely entirely on manual analysi...

Problems solved by technology

When a power grid fault occurs, the system can transmit a large number of accident messages in a timely manner, but it cannot analyze and judge the fault itself, and cannot directly prompt the fault situation from the system

Fault diagnosis and fault treatment rely entirely on manual analysis and processing, relying largely on the operation experience of dispatchers, lack of auxiliary decision-making systems for accident handling, and cannot provide direct and effective accident handling decision-making solutions, which ultimately leads to the efficiency of power dispatching and grid fault handling. decrease in accuracy
