Smart meters are one of the basic devices for data collection in smart grids (especially smart distribution networks). They undertake the tasks of collecting, measuring, and transmitting raw electrical energy data. They are the basis for information integration, analysis, optimization, and information display. In addition to the measurement function of the basic electricity consumption of traditional electric energy meters, smart meters also have two-way multi-rate measurement functions, user-side control functions, and two-way data communication modes in order to adapt to the use of smart grids and new energy sources. Intelligent functions such as function and anti-theft function.
The advanced measurement system and automatic meter reading system built on the basis of smart meters can provide users with more detailed power consumption information, so that users can better manage their power consumption, so as to save electricity costs and reduce greenhouse gas emissions. Goals; power retailers can flexibly set time-of-use electricity prices based on user needs and promote the reform of the electricity market price system; distribution companies can more quickly detect failures and respond in a timely manner to strengthen power network control and management.
The intelligent instrument defined in China is based on a microprocessor, which can store measurement information and can analyze, synthesize and make various judgments on the measurement results in real time. It generally has automatic measurement functions, powerful data processing capabilities, automatic zero adjustment and unit conversion functions, can perform simple fault prompts, has a human-computer interaction function, is equipped with an operation panel and a display, and has certain artificial intelligence. Generally, the electronic multi-function energy meter using a microprocessor is defined as a smart meter, and features such as communication functions (carrier wave, GPRS, ZigBee, etc.), multi-user metering, and specific user (such as electric locomotive) metering are introduced into the smart meter. In concept.
Combining various definitions, it can be considered that the smart meter is an intelligent instrument with microprocessor application and network communication technology as the core. It has the capabilities of automatic measurement / measurement, data processing, two-way communication, and function expansion. / Local communication, real-time data interaction, multiple electricity price billing, remote power cut, power quality monitoring, water and gas meter reading, interaction with users and other functions. The smart metering system built on the basis of smart meters can support the requirements of the smart grid for load management, distributed power access, energy efficiency, grid dispatching, power market transactions, and emission reduction.
