Multi-channel measurement device and method for resident loads

Abstract

The invention discloses a multi-channel measurement device and method for residential loads. The device comprises analog-to-digital converters, a signal conditioning module, a communication module, asignal processor, a synchronous clock module, a high-speed storage module and a power conversion module. The input terminal of the signal conditioning module is connected with three analog-to-digitalconverters. The input terminals of the three analog-to-digital converters are respectively connected with current / voltage acquisition units arranged in a socket circuit, an air conditioner circuit anda lighting circuit and are used for acquiring voltage and current data of the socket, air conditioner and lighting circuits, and the output terminal of the signal conditioning module is connected with the signal processor; the synchronous clock module and the high-speed storage module are respectively connected with the signal processor, and the signal processor is connected with a system main station through the communication module. According to the invention, respective advantages of non-intrusive measurement and accurate independent measurement are fully utilized to carry out subentry measurement on resident load electricity consumption.

Description

technical field [0001] The invention relates to a multi-channel measuring device and method for residents' load, belonging to the technical field of load measuring. Background technique [0002] In recent years, with the development of my country's economy and the acceleration of urbanization, the continuous increase of urban population has led to an increasing trend in the total electricity load of residents, and its proportion in the overall electricity load of the power grid has continued to increase. However, the measurement of the total residential electricity load can no longer meet the current application requirements of power companies in terms of customer service, energy saving and efficiency enhancement, electricity safety, and demand-side management. The sub-item load management system is an effective way to solve the above needs. [0003] At present, the sub-item measurement of residential load electricity generally adopts an independent intrusive measurement me...

Problems solved by technology

The intrusive method requires a large number of measuring devices. Although the measurement is accurate, in some places where it is inconvenient to install measuring devices, line modification is required, and the cost of device deployment and maintenance is relatively high.

With the non-intrusive measurement method, only a single measurement point of the main entrance is used to obtain the results of the non-intrusive load decomposition algorithm. With the characteristics of the decomposition target itself and the background interference of the power consumption environment, its accuracy is often not ideal. reached the estimated level
