Embodiment Construction

[0018] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ...

Abstract

The invention relates to an abnormal state detection method. The method comprises the steps of obtaining state data of electronic equipment; Equally dividing the state data into a plurality of sequences and carrying out sequence abnormity operation to obtain the number of abnormal sequences; Performing clustering operation on the state data, and obtaining a plurality of clusters; Calculating the sum value of the number of the data points in the state data and the intersection of all the clusters as a null set, and judging that the state data is abnormal when the sum value is greater than a first preset value and the number of the abnormal sequences is greater than a second preset value; And sending a state abnormity response to the monitoring equipment. The abnormal state detection methodcomprises the following steps: obtaining the number of abnormal sequences through similarity operation on a plurality of sequences; And performing clustering operation on the current state data to form a plurality of clusters. Only the number of data points with the intersection of the current state data and all clusters as a null set and the number of abnormal sequences reach a certain number, itis determined that the state data of the current group are abnormal, it is convenient to determine the abnormal state in advance, and therefore early warning is provided conveniently.

Description

technical field [0001] The invention relates to the technical field of power grid security, in particular to an abnormal state detection method. Background technique [0002] The healthy operation of power equipment is the basis for the safe operation of the power grid. The detection of power equipment has become a necessary condition for its safe operation. The traditional detection of abnormal state of power equipment adopts the threshold method. [0003] However, due to the diversity of power equipment types, operating conditions and operating environments, the parameters of power equipment change with time, and the fixed threshold detection and judgment method cannot guarantee universal applicability to different types of equipment in different regions. It cannot meet the high requirements for the safe operation of the power grid. Especially when the state of the power equipment is abnormal due to insulation aging and other reasons, if the change of the equipment state ...
