A method and device for rapidly detecting abnormality of key electric power indicators

Abstract

The present invention relates to a method and device for fast abnormal detection of key electric power indicators. In the method, a certain KPI data is collected at each detection point of the power grid to form a series of KPI data, and then the upper and lower levels of the KPI data collected at each detection point are The limits are normalized respectively, and the normalized upper limit and lower limit are simultaneously displayed in a polar coordinate, and the upper and lower limits of the normalized KPI data collected by each detection point are respectively displayed in concentric circles On the circumference of the circle, the polar coordinate value of the KPI data of the detection point is displayed in the annular zone between the inner circle and the outer circle as normal data and displayed as data points, and the polar coordinate value is displayed in the KPI of each detection point outside the annular zone The data is abnormal data, and the value and equipment information are displayed at the corresponding point of the abnormal data. This method enables dispatchers to quickly grasp the operating status of the power grid, handle abnormalities in a timely manner, and does not need to pay attention to a large amount of normal data, and effectively improves the decision-making efficiency of dispatchers for power generation adjustment.

Description

technical field [0001] The invention relates to the technical field of power grid operation safety, in particular to a method and device for quickly detecting abnormality of key electric power indicators. Background technique [0002] A large amount of data will be generated during the operation of the power network. Finding key information from these data and mastering the operating status of the power system are of great significance for dispatchers to improve the decision-making efficiency of power generation adjustment. Key performance indicator KPI (KeyPerformance Indicator, referred to as key indicator), shows the operation status of the power grid in a concentrated manner, and provides information about the safety, economy, quality and environmental protection of the power grid operation for the company's senior decision-makers and personnel in key positions in the power grid operation. Through the monitoring of KPIs, problems such as safety hazards, uneconomical oper...

Problems solved by technology

[0004] Aiming at the problems in the prior art that it is necessary to browse a large amount of data to understand the operation state of the power grid and search for KPI abnormal information, the work intensity is high, the efficiency is low and it is easy to miss, a method for quickly detecting the abnormality of key electric power indicators is provided, and the normalization technology is adopted Simultaneously display a set of series of power KPI data in the polar coordinate system. This method enables dispatchers to quickly grasp the operating status of the power grid, handle abnormalities in a timely manner, and does not need to pay attention to a large amount of normal data, and effectively improves the decision-making efficiency of dispatchers for power generation adjustment.
