Problems solved by technology

[0003] The traditional load monitoring only measures the total power at the power entrance, but fails to detail it to the various electrical equipment inside the user. At the same time, it will also weaken the user's power consumption experience and energy-saving awareness. How to be used and consumed, it is impossible to formulate effective energy-saving control measures (such as purchasing energy-saving equipment in a targeted manner) and more efficient energy consumption methods (such as formulating a reasonable energy-saving plan). According to relevant data, home users in In the case of knowing the detailed electricity consumption information of residential appliances in a timely manner, the monthly electricity bill may drop by 5% to 15%, and even purchase more energy-saving electrical equipment. Therefore, when users do not know the detailed electricity consumption information of residential appliances case, the increased carbon emissions are equivalent to the additional use of 8 million cars

Embodiment 1

[0028] refer to Figure 1-3 , a method for laboratory electricity load decomposition monitoring, is characterized in that, comprises the following steps:

[0029] S1: First collect data, collect real-time voltage and current information from the user's indoor power entrance, and convert them into digital signals through the A / D converter, and then combine the data communication module to transmit the data to the load decomposition processor for further processing. analyze;

[0030] S2: Decompose the load through the load decomposition processor: read the voltage and current waveforms at the user's main incoming line; To express the current characteristics, the sliding window bilateral CUSUM detection algorithm is used to extract the transient characteristic quantities such as pulse amplitude and start time during the load start-stop process; the power size classifier is realized by cluster analysis method, the harmonic ratio Classifiers, equipment duration classifiers, etc. ...

Embodiment 2

[0040] refer to Figure 4 , a method for monitoring laboratory electricity load decomposition. Compared with Embodiment 1, in this embodiment, in order to increase the accuracy of load decomposition, a rollback mode is introduced in the load state tracking and identification, that is, when an obvious identification error is found , read the saved previous state, then quickly analyze and recurse, search for the hidden maximum possible load state, and then continue to track and identify the state of the electrical equipment.

Abstract

The invention belongs to the technical field of power load detection and decomposition, especially to a laboratory electrical load decomposition monitoring method. Traditional load detection cannot berefined and deeply applied to each electric device in a user, and the power use experience and energy saving consciousness of a user can be weakened. The method comprises the following steps of: performing data acquisition and communication: and acquiring real-time voltage and current information from an indoor power inlet of a user, and converting the real-time voltage and current information into digital signals through an A / D converter. The laboratory electrical load decomposition monitoring method is convenient for users to reasonably arrange the starting time of an electric appliance, responds to the tiered electricity price and reduces the power consumption to the maximum extent, and the electric power company can associate multi-source information such as user occupations and housetypes to accurately classify the electricity consumption habits of the users and formulate an electric power sales strategy, thereby providing bottom-layer technical support for marketing business ofthe company after electricity transformation, and providing bottom-layer data support for government departments to formulate next-step energy policies.

Description

technical field [0001] The invention relates to the technical field of electric load detection and decomposition, in particular to a method for laboratory electric load decomposition monitoring. Background technique [0002] The power grid is an important carrier and main form of energy transmission, distribution and use, as well as an important public service resource. Its efficiency has a major impact on other fields and industries. Extensive research on energy" technology, most of the electricity used by people is ultimately derived from fossil fuels, then saving electricity has a direct and key effect on the sustainable development of the environment and economy, and thus produces a support for saving electricity , High-efficiency power consumption technology and equipment market demand. [0003] The traditional load monitoring only measures the total power at the power entrance, but fails to detail it to the various electrical equipment inside the user. At the same tim...
