Problems solved by technology

[0003] The existing research and literature have studied the model and operating characteristics of the load of the breaker, but there is no literature that proposes an accurate, effective and rapid identification of the load of the breaker. According to the real-time average of the breaker The power and the time-domain law of the third harmonic current, the method to judge whether it is the start-up of the breaker

Embodiment Construction

[0033] In order to make relevant persons understand the technical content of the present invention better, the specific embodiments are now described as follows in combination with the accompanying drawings.

[0034] Such as figure 1 As shown, a non-invasive identification method of a wall breaker in the present invention includes the following steps:

[0035] Step 1: Use voltage and current sensors to collect voltage and current signals at the user's main incoming line to form a sampling sequence u and i of voltage and current. Among them, u and i are the sampling sequence of the voltage signal after pretreatment such as filtering and denoising, and the sampling frequency is selected as 1kHz in this article.

[0036] Step 2: Scan the voltage signal u and current signal i, and calculate the steady-state average power increment ΔP and the time Δt required for a sudden change 1 .

[0037] Depend on figure 2 It can be known that when the Supor wall breaker operates independe...

Abstract

The invention discloses a non-intrusive identification method for a high-speed blender. The method includes the following steps: step 1, collecting voltage and current signals at a total incoming lineof a user by using voltage and current sensors to form a sampling sequence u, i of the voltage and current; step 2, scanning the voltage signal u and the current signal i, calculating a steady-stateaverage power increment deltaP and the time deltat1 required for mutation; step 3, calculating the difference deltaI1 between the maximum third harmonic current after the mutation and the steady-statethird harmonic current before the mutation and the time deltat2 required for this segment of mutation; step 4, calculating the difference deltaI2 between the third harmonic current before and after the mutation and the time deltat3 required for the mutation; and step 5, calculating the ratio k of the steady-state average power increment to the mutation time. The scheme of the invention can accurately, effectively and quickly identify the high-speed blender, and has the advantages of simplicity, economical efficiency, easy popularization and application and the like.

Description

technical field [0001] The invention belongs to the field of electric power research, and specifically relates to a non-invasive identification method for a wall breaker. Background technique [0002] Residential load is an important part of power load, and its proportion of power consumption is gradually increasing. Therefore, it is an urgent need to establish an intelligent power consumption system that can realize the visualization of household power consumption. According to the power consumption of each electrical equipment, make a reasonable energy-saving plan, purchase energy-saving equipment in a targeted manner, and test the energy-saving effect, so as to reduce energy consumption and electricity bills. The visualization of electricity consumption is also considered to be one of the effective means of stabilizing peak electricity consumption. It can encourage users to choose electricity consumption during low-valley electricity price periods such as nighttime, so as...
