Embodiment Construction

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

[0039] like figure 1 As shown, a schematic diagram of the main flow of an embodiment of a method for managing abnormal power quality data provided by the present invention is shown. In this embodiment, the method includes the following steps:

[0040] Step S10: Read the power quality monitoring terminal data, and for each read data, use a pre-selected abnormal data judgment model for judgment to determine whether the data is abnormal; the abnormal data judgment model is trained by machine learning ; It can be understood that the machine learning can be implemented by using machine learning languages ​​commonly used in the market;

Abstract

The invention discloses a power quality abnormal data management method, device and system. By introducing the recognition model of the power quality abnormal data, the power quality abnormal data canbe automatically recognized and processed, so that the power quality statistical result can correctly and truly reflect the operation condition of the power system. The abnormal data is managed in the electric energy quality data collection process, the proportion of the abnormal data in the database is reduced, and the quality of the electric energy quality data and the credibility of the electric energy quality analysis result based on the data are improved.

Description

technical field [0001] The invention relates to the technical field of data management, in particular to a method, device and system for managing abnormal power quality data. Background technique [0002] One of the characteristics of the power quality monitoring system is the large amount of data. The large amount of data brings a series of problems such as storage space and query efficiency, one of which is the problem of abnormal data processing. [0003] The main reasons for abnormal power quality data are as follows: [0004] Due to the normal overhaul, maintenance, and temporary adjustment of the operating state of the power system, the steady-state index of power quality exceeds the standard for a long time, for example, the supply voltage drops to zero during the entire overhaul period. [0005] Due to various transient events in the power system, such as voltage interruption, voltage swell, voltage sag, etc., the steady-state indicators of power quality in a short...
