Against the backdrop of the accelerated penetration of the digital economy and the steady advancement of the construction of a new-type power system, the accuracy of electricity metering and the intelligence level of power supply services have become key supports for ensuring enterprise production and operation and promoting the high-quality development of the regional economy. To continuously improve the accuracy of electricity metering and the level of power supply services, and consolidate the foundation for grid intelligence, State Grid Xuchang Power Supply Company has based itself on the local development needs, taken the intelligent electric meter replacement project as a key livelihood task and a core task for grid upgrading, and promoted it in a well-planned and efficient manner. With "accurate metering" as the pen and "intelligent service" as the ink, it has injected strong electric power momentum into the industrial development and people's well-being improvement of Xuchang City.
Focusing on Industrial Pain Points, Targeted Promotion of Meter Upgrading in the Park
In August, Xuchang was still in the sweltering heat, and the Mafang Town Plate Industry Park was bustling with the roar of machines. As a local gathering area for characteristic industries, the park houses dozens of plate processing enterprises. During the peak summer production period, the electricity load continues to rise, putting forward higher requirements for power supply reliability and metering accuracy. Previously, some enterprises reported that the old electric meters had problems such as fluctuating metering errors and delayed data feedback, which not only affected the enterprise's cost accounting but also brought inconvenience to production scheduling.
In response to this situation, State Grid Xuchang Power Supply Company took the initiative to provide services, set up a professional team composed of metering technical backbones and power operation and maintenance personnel, and conducted on-the-spot investigations in the park. By analyzing the electricity load data and visiting enterprises to understand their demands, a targeted upgrading plan of "hidden danger inspection + faulty meter replacement + comprehensive maintenance" was finally formulated. On August 28, the upgrading work was officially launched. The staff, braving the high temperature of over 35℃, carried professional testing equipment to carry out door-to-door operations. In the factory area of Tenghe Plate Processing Enterprise, the staff checked the data and tested the accuracy of the original electric meter. After confirming that there was a metering deviation, they quickly removed the old equipment and installed a new intelligent electric meter. The new electric meter adopts high-precision sensors and digital transmission technology, which can not only collect electricity consumption data in real time but also realize data synchronization and abnormal early warning through a remote system, completely solving the problems of "delayed data and uncontrollable errors" of traditional electric meters.
At the same time, the staff did not limit themselves to meter replacement but extended the service to a comprehensive "physical examination" of the meter box and supporting equipment. They carefully checked the contact status of the metering switch, tested the on-off performance and operation reliability with special tools to ensure that the switch could safely carry current and switch on and off reliably under high load conditions; they checked each incoming and outgoing line in the meter box one by one, focusing on verifying whether the wire insulation layer was intact and whether the connection points were firm without heat oxidation. The 3 cases of line aging and 2 cases of loose contacts found were rectified on the spot. "The electricity load is high in summer. These seemingly small hidden dangers are likely to cause equipment failures or even power outages. The more careful we are, the more guarantee the enterprises' production will have," said Master Wang, the person in charge of the on-site operation, while tightening the line connectors and explaining to the enterprise's person in charge.
Improving the Service Mechanism to Ensure Efficient and Convenient Upgrading Work
The upgrading of intelligent electric meters is not only the update of equipment but also the optimization of the service process. State Grid Xuchang Power Supply Company is well aware that improper coordination during the project promotion process can easily affect the normal production of enterprises. Therefore, the company has established a "full-process coordination and full-cycle guarantee" service mechanism to make the upgrading work both "efficient" and "warm".
In the project preparation stage, considering the concentration of enterprises in Mafang Town Plate Industry Park and their urgent demand for electricity, the company communicated in advance with the park management committee and various enterprises, formulated a detailed operation schedule, clarified the number of households to be replaced daily and the specific time periods, and announced the power outage plan 3 days in advance through channels such as park notices and enterprise WeChat groups to minimize the impact on enterprise production. For some enterprises that carry out continuous production 24 hours a day, the staff even took the initiative to adjust the operation time and carried out construction during the intervals of the enterprises' production to ensure that "replacement does not delay work and upgrading does not affect production".
During the operation process, the company strictly implemented the power safety operation regulations. Each operation team was equipped with a safety supervisor. Before the operation, potential hazards were analyzed one by one, the status of insulating tools was checked, and insulating gloves, safety helmets and other protective equipment were provided for the staff to resolutely prevent safety accidents. At the same time, a "one person, one meter, one file" system was established. The staff recorded the meter reading data before and after the meter replacement on the spot, took video materials of the equipment replacement, and obtained the signature confirmation of the enterprise's person in charge to ensure that the metering data was transparent and traceable.
In the link of online system synchronous update, the company arranged special personnel to be responsible for data entry and verification, checked the customer name, contact information, meter asset number and other information item by item, and accurately matched them with the offline files to avoid billing problems caused by data errors. "In the past, when replacing electric meters, we always worried about problems in data connection. This time, the power supply company was open and transparent throughout the process and took the initiative to explain the use method of the new electric meter to us. It's really considerate," said the person in charge of Tenghe Plate Processing Enterprise, holding the instruction manual of the new electric meter.
Releasing Upgrading Dividends, Empowering High-Quality Development with Accurate Metering
The upgrading of intelligent electric meters has not only solved the "urgent issues" of enterprises but also brought tangible dividends to the regional economic development. For the enterprises in the park, the "data transparency, convenient payment and accurate billing" brought by the new electric meters have given them more confidence in production and operation. Through the mobile APP, the enterprise's person in charge can check the electricity load curve and electricity consumption data in real time, and reasonably adjust the production plan according to the electricity consumption situation, effectively reducing the electricity cost. "In the past, the monthly electricity fee depended entirely on the meter reading. Now we can see the electricity consumption in real time. We have optimized the production schedule, and the monthly electricity fee has been reduced by about 5% compared with before," said the financial director of a large plate processing enterprise, calculating an "economic account".
From the perspective of power supply enterprises, the popularization and application of intelligent electric meters have greatly improved the success rate of electricity collection and data accuracy, providing data support for the refined management of the power grid. By analyzing the real-time electricity consumption data collected by intelligent electric meters, State Grid Xuchang Power Supply Company can accurately grasp the change law of regional electricity load, predict the electricity peak in advance, optimize the grid operation mode, and improve the power supply reliability. At the same time, the fault early warning function of intelligent electric meters can timely detect problems such as line overload and meter abnormalities. The staff can locate the fault point through the remote system and carry out emergency repair quickly, reducing the power outage time to 1/3 of the original.
The intelligent electric meter upgrading action in Mafang Town Plate Industry Park is just a microcosm of State Grid Xuchang Power Supply Company's practice of the concept of "accurate metering and intelligent service". Up to now, the company has completed the replacement of more than 200,000 intelligent electric meters in the city, covering industrial enterprises, residential communities, commercial places and other fields. In the next step, State Grid Xuchang Power Supply Company will continue to accelerate the pace of intelligent electric meter replacement, aiming to achieve coverage of intelligent electric meters in the city within the year. At the same time, it will further expand the application scenarios of intelligent electric meters, promote the innovation of the "intelligent electric meter +" service model, such as providing value-added services such as electricity consultation and energy-saving diagnosis for enterprises through intelligent electric meter data, to help enterprises achieve green and low-carbon development.
From ensuring enterprise production to serving people's electricity consumption, from consolidating the grid foundation to promoting industrial upgrading, State Grid Xuchang Power Supply Company has taken the upgrading of intelligent electric meters as a starting point, used accurate metering to safeguard the development momentum, and used high-quality services to convey the warmth of electricity, injecting a steady stream of "electric power vitality" into the construction of a modern industrial system and the realization of high-quality development of Xuchang City.
