<p>The present invention relates to an abnormal power key performance indicator (KPI) quick detecting method and device, the method comprising: first, acquiring certain KPI data at each detection point of a power grid to form an array comprising a set of KPI data; next, normalizing an upper limit value and a lower limit value of the KPI data at each detection point respectively, and simultaneously displaying the normalized upper limit values and the normalized lower limit values on the circumferences of concentric circles in polar coordinates; when lying in the annular band between an inner circle and an outer circle, the polar coordinate values of the KPI data at each detection point are normal data and are displayed as data points; and when lying outside the annular band, the polar coordinate values of the KPI data at each detection point are abnormal data, the values and device information being displayed at the points corresponding to the abnormal data. The method enables schedulers to quickly know the operational status of the power grid and timely handle abnormalities rather than focus on massive normal data, thus effectively improving decision-making efficiency of schedulers in power generation adjustment.</p> |
