1. The smart energy meter application is used to serve power customers
Smart energy meters can provide users with electricity consumption information and energy consumption data. Through data comparison, it can reflect the difference between energy-saving products and high-energy-consuming equipment, and guide users to adopt advanced energy-saving technologies and high-efficiency equipment to improve the end-use electricity efficiency.
At the same time, it can provide users with scientific electricity advice, electricity information, notice of power outages, and reminder information, etc., to strengthen the management of electricity marketing.
2. The smart energy meter application to improve the accuracy of load forecasting in distribution networks
In the distribution network, due to factors such as many load nodes, diverse parameters, incomplete meters, and lack of real-time monitoring equipment, it is difficult to obtain accurate load data. .
Using the smart energy meter and the terminal to input data to the main station in time through the channel can reduce the influence of uncertain factors and improve the accuracy of load forecasting.
3. Smart energy meter application to intelligent demand side management
Demand-side management refers to a management mode in which both parties of electricity supply and demand jointly manage the electricity market in order to improve the reliability of power supply and reduce energy consumption and expenses for both parties.
It uses economic incentives as the main means to guide and stimulate the majority of power users to optimize the way of electricity consumption, improve the efficiency of terminal electricity consumption, and realize the project of energy-saving management system.
The application of smart energy meters can monitor the operation status of the power grid in real time, track and monitor the whole process of users' electricity consumption, determine the optimal operation and load control plan, optimize the electricity consumption plan, and guide users to transfer loads through a reasonable electricity price structure, consciously shifting peaks. Fill the valley, flatten the load curve.
4. The smart energy meter application for the cost control function
There are two ways to realize the cost control function: local and remote. Local fee control implements fee control locally through solid-state media such as CPU cards and radio frequency cards. The charge control function of the local charge control electric energy meter is realized inside the smart electric energy meter. The remote cost control is the main station, and the electricity sales system uses the virtual medium to recharge and set the cost control function. The functions realized by the remote charge control are equivalent to those realized by the local charge control.
5. The smart energy meter application is for the measurement of the maximum demand
Smart meters measure bi-directional and time-based maximum demand, display date and time, and store time-stamped data. When the voltage line is powered on, time period conversion, reset, clock adjustment, etc., the energy meter starts from the current moment, and measures the demand according to the demand cycle. When the first demand cycle is completed, it starts according to the slip interval. Maximum demand measurement. During an incomplete demand period, no record of maximum demand is made.
6. Smart energy meter applications are used in the measurement of electric energy
Smart meters can measure and store various types of electric energy and electric energy data according to preset time intervals, and have forward and reverse active and four-quadrant reactive energy measurement functions, which can be combined through software programming. It also has the function of time-sharing metering, which can accumulate and store total, peak, peak, flat and valley active energy and reactive energy respectively according to the corresponding time period.
