Embodiment Construction

[0029] Such as figure 1 Shown is a flow chart of the method of the present invention: the non-invasive real-time monitoring method for household load switching events provided by the present invention includes the following steps:

[0030] S1. Control parameter initialization, specifically including setting the voltage sampling frequency, current sampling frequency, single active power calculation step, the number of active power points in the steady-state window, the average active power of the previous steady-state window, and the average active power of the current steady-state window and power jump detection threshold;

[0031] S2. Cache the voltage sampling data and current sampling data of the household electrical system, and calculate the active power value; specifically, calculate the active power according to the single power calculation step value until the number of active power points in the cache reaches the set steady-state window active power. number of power p...

Abstract

Disclosed is a monitoring method of a non-invasive household load switching event in real time. The monitoring method of the non-invasive household load switching event in real time comprises the control of the parameters initialization, the calculation of the active power value, the judgment of the steady-state of the active power and the judgment of the load switching event. The monitoring method of the non-invasive household load switching event in real time, without the intrusion into the load inside, has the technical characteristics of high monitoring precision of a bound of the steady and transient state of the load event, strong fluctuation robustness of the active power, a small amount of calculation, a flexible configuration. The monitoring method of the non-invasive household load switching event in real time can provide a reliable basis for all kinds of the non-invasive load identification technologies and the classification measurement technologies.

Description

technical field [0001] The invention specifically relates to a non-invasive real-time monitoring method for household load switching events. Background technique [0002] The world's energy problems are becoming more and more serious, and energy conservation and emission reduction have long become the focus of attention from all walks of life. Taking home users as an example, Google research shows that if home users can keep abreast of detailed electricity consumption information of residential appliances, they can reduce their monthly electricity bills by 5% to 15%. Efficient classification and detection of power consumption loads can provide important references for optimizing power consumption patterns and improving power consumption habits, and can reduce power consumption expenses without affecting their normal life. [0003] Non-intrusive Load Monitoring (NILM) is easy to install and use, and data collection and information analysis has become a research hotspot in th...
