Abstract

The invention discloses a non-invasive method and a system for monitoring an electric load alarm. The method comprises the following steps: obtaining a terminal voltage and a total current at the inlet of an electric load power supply at the current moment; performing electric load characteristic extraction on the terminal voltage and the total current to obtain an electric load characteristic atthe current moment; performing electric load decomposition on the terminal voltage and the total current according to the current electric load characteristic; obtaining a type, a current working state and current electric consumption information of each electrical equipment in the electric load; and generating electric consumption abnormal alarm information of the electrical equipment according to the current electric consumption information and a reference electric consumption information. Once any of the current electric consumption information of the electrical equipment is abnormal, the system can timely discover it and give an alarm. Users can timely view and process the abnormal condition according to the type, the current working state and the abnormal electric consumption information of the electrical equipment with abnormal electric consumption in the abnormal electric consumption alarm information of the electrical equipment.

Description

technical field

[0001] The invention relates to the technical field of non-intrusive electric load monitoring, in particular to a non-intrusive electric load alarm monitoring method and system. Background technique

[0002] In recent years, with the continuous improvement of the national economy and people's living standards, the growth of industrial and residential electricity consumption, industrial electrical equipment and household appliances are increasing. There are two problems in the current way of using electrical equipment: one is that the energy consumption is too high, which fails to optimize the user's electricity consumption habits, and the other is that there is no effective prompt method when the energy consumption of electrical equipment is abnormal. This is also something that will definitely appear in the process of economic development and energy-saving technology development. The emergence of these problems also puts forward new requirements for power lo...
