Electric power key indicator abnormity rapid detecting method and device

Abstract

The invention relates to an electric power key indicator abnormity rapid detecting method and device. The method comprises the steps of collecting some KPI (Key Performance Indicator) data on each detection point of a power grid to form a sequence composed of a group of KPI data; performing normalization processing on the upper limit value and lower limit value of the KPI data collected at each detection point; displaying the upper limit value and the lower limit value which are subjected to normalization processing in polar coordinates at the same time; respectively displaying the upper limit value and the lower limit value of the KPI data collected at each detection point, which are subjected to normalization processing, on the peripheries of concentric circles; when the polar coordinate values of the KPI data of the detection points are displayed on an annular belt between an inner circle and an outer circle, the KPI data are taken as normal data and are displayed in data points; the KPI data of the detection points of which the polar coordinate values are displayed outside the annular belt are taken as abnormal data; displaying numerical values and equipment information at the points corresponding to the abnormal data. According to the method, a dispatcher can rapidly master the running state of the power grid, deals with the abnormity in time, and does not need to pay attention to a great amount of normal data, and the power generation adjustment decision-making efficiency of the dispatcher is effectively improved.

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 (Key Performance Indicator, referred to as key indicator), shows the operation status of the power grid in a concentrated manner, and provides information on 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 power grid operation. Through the monitoring of KPIs, problems such as safety hazards, uneconomical operation,...

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.
