Energy meters themselves do not possess energy-saving features. However, they are capable of accurately measuring a user's electricity consumption. Real-time monitoring and statistical analysis of electricity data can help users understand their electricity usage patterns and current energy consumption. Whether residential users, industrial users, or power operators analyze the electricity consumption data recorded by energy meters, they can discover energy modes and energy consumption problems. Then, they can take measures to reduce energy waste, provide support and guidance for energy conservation.
With the advent of smart energy meters, electricity data can be feedback to users in real time. By combining real-time electricity data with usage patterns of household electrical appliances, users can analyze their primary energy consumption. For instance, if a user discovers that their air conditioner has been running for an extended period, they can implement strategies like setting timer switches on or off and adjusting the temperature to decrease the energy usage of their air conditioner. By discovering the neglected energy waste of household appliances in standby mode, we can improve our awareness of energy conservation.
Industrial equipment typically requires a significant amount of electricity for its operation, making it essential to understand and manage energy consumption effectively. Energy meters can provide real-time electricity consumption data, allowing factory managers to monitor the energy consumption of each production process in real time. This enables them to identify and resolve any issues related to energy wastage quickly. Effective analysis of electricity consumption is necessary in factories, and a single total meter is insufficient. Separate energy meters must be installed at key nodes, high energy-consuming equipment, and other areas. Correct installation of separate energy meters can diagnose high energy-consuming points, energy waste points, and points where production capacity and energy consumption do not match. Factory managers can implement targeted energy-saving measures, including improving production processes, enhancing equipment efficiency, and conducting energy consumption assessments, in order to effectively save energy. Energy meter grading and data analysis can help balance power loads and detect line losses in factories, resulting in energy savings.
Real examples of factory energy saving:
1. Waste was found and equipment was renovated to save up to 30 kWh per hour, 330 kWh per day, 9,900 kWh per month, and nearly 100,000 kWh per year. If industrial electricity is priced at 1 yuan/kWh, then 1 million yuan can be saved annually.
There is an smt workshop in this factory that operates around-the-clock, unlike most other workshops that typically conclude their duties by 9 pm and resume at 8 am the following morning. The smt work shop and other workshops share an exhaust ventilation pipeline that needs to be opened for use. After installing separate energy meters for the factory, using energy meters and classifying the metering, security personnel discovered that the energy consumption of one of the energy meters remained high late at night. Feedback was provided to the relevant department. The management department arranged personnel to analyze the problem and discovered that the shared issue was with the exhaust pipe. The pipeline was immediately rectified, and an independent exhaust pipe for the smt was established. The total motor power of the main pipeline amounted to 35 kW. However, the smt pipe fan requires only 5 kW, resulting in an energy savings of 30 kW in the smt workshop after 21:00.
2. The owner of the injection molding factory discovered that the injection molding machine had not been fully powered down at the end of the day.
An injection molding factory installed a separate energy meter for each injection molding machine to achieve independent metering and link energy consumption with production volume. After work every day, the factory boss checks the power data situation using the grading metering system platform. In the early stages, he discovered that the injection molding equipment had not been fully shut down. After a period of monitoring, training, and management, these incidents were resolved.
Energy meters not only provide real-time energy consumption data, but they can also predict future electricity demand based on historical data. Power operators can plan and adjust electricity supply based on historical data to meet future electricity demands and avoid power shortages or surpluses.
Although energy meters themselves do not possess energy-saving features, they can aid and direct individuals' energy conservation endeavors by measuring and analyzing electrical data. They can help users better understand and manage their energy consumption, optimize production processes, reduce costs, and improve efficiency. With the development of smart grid technology, the functions and performance of energy meters will continue to improve, providing more opportunities for energy savings and innovation in the future.
