Ji Hongliang is director of the Changjiaba Power Supply Office of Shaanxi Electric Power Foping Power Supply Branch. When he entered the power system in 2001, he was responsible for meter reading. Over the past 15 years, with his growth, meter reading methods and meter reading techniques have also constantly changed. In Ji Hongliang's view, it is even more critical that people must work hard to change themselves and try to adapt to changing methods and technological advances.
The meter reading shortens the time, but it does not mean that it is idle.
A copybook and a calculator are the memories of Ji Hongliang’s initial meter reading. “A monthly copy of the table, direct use of the meter to record the user's electricity situation, because the user is more dispersed, copy, nuclear, receive each month have to use It took ten days to complete this work."
With the continuous progress and development of science and technology, the use of smart meters has gradually been promoted and applied in rural areas. The number of households in the Changjiao Dam area has gradually increased. Due to the new technology and new functions of the system, the monthly reading of electricity by electric power employees has shortened the time. This is a great surprise and happiness for the copying and collecting personnel of the power supply station. That is, they reduced the workload of meter reading and running, and saved time for charging.
Collecting meter readings not only “saves†meter readers, but also equipment. The meter readers who are relaxed are not really "free". For them who are "more than a few," they begin to think about how to maintain the line, manage the equipment, and how to reduce the line loss.
“Because of the large amount of meter reading, in order to complete the task of meter reading on time, it is sometimes difficult to avoid the operation and maintenance of the equipment.†Since the installation of the meter collection system for power supply installation, the meter reading time has been reduced, freeing up more time for serious inspections. Equipment status, and timely processing of simple equipment abnormalities. Qian Zhanlin, who is in charge of supplying power to the remote mountainous area of ​​Changjiao Dam, said.
Automatic collection of active "play", so that new technology really play a role "Before, manual meter reading technology content is not high, but it is time-consuming and laborious, with remote collection copy, the meter reader just sitting in front of the computer, click the mouse, The batch meter reading and data entry work can be completed.†Chang Jihong, chief of the Changjiaba Power Supply Institute, said this with emotion.
After catching the “Technology Expressâ€, the phenomenon of wrong copying and missed copying can be completely eliminated, and the readers' work focus will be biased toward accurate analysis and control of electricity charges, line losses, etc. Occasionally, information about the missing mining will be carried out. Supplementary copy. With the improvement of the system, the probability of this copying will become smaller and smaller.
In the past, special surveys and inspections were required to be carried out on site. If there was a lack of clear evidence for electricity recovery during measurement failures, the situation was greatly improved after perfecting the special transformers in 2016. At any time, key data such as current indications, secondary currents, voltages, and power factors of each special variable metering unit are retrieved, so that the specific measurement operation can be accurately judged.
After the new equipment is installed, how to operate it well and let it play its due role becomes the key. “We began installing automatic collection devices at the end of 2015. When we started, we were not familiar with the equipment and we asked the Marketing Department for help as soon as the equipment became a problem. This resulted in a lower on-line rate of equipment.†This year's automatic collection device installation Among them, several employees, including Ji Hongliang, personally “played the battle,†not only learning and installing, operating, and operating with factory technicians, but also operating by themselves.
At the same time, the power supply station also carried out a thorough clean-up of the installed equipment, resolved problems in a timely manner, and actively involved in the operation and maintenance of the equipment. Through strengthening the operation and maintenance efforts, the employees' trust and application of the system are strengthened so that they can truly play a role.
In-depth application to provide better services In mid-June this year, technicians from the company’s technicians, marketing department, and other personnel came to the Changjiaba Power Supply Station to conduct an on-the-spot inspection of the 10 kV 125 Long Line. Its purpose was to Pilots carried out deep application of measurement automation.
“Selecting the long-angle dam power supply as a pilot point focuses on the coverage rate of the automatic collection device.†Field technicians said that through deep application, a large amount of measurement data will be excavated and analyzed, and the value of the data will be applied to power supply management. , Anti-Theft, Accurate Sales Expansion, Service Enhancement and other fields.
“This will be the driving force for us to further improve the quality of service.†Director Ji Hongliang believes that with the continuous increase in the coverage rate of automatic metering devices, the effective use of these mass data will provide the basis for improving the accuracy of services. For example, it is possible to accurately predict load changes through the trend of changes in user power consumption, facilitating the adoption of targeted safeguards.
Nowadays, new technologies and new ideas are stimulating changes in management methods at the Longhorn Dam power station. Next, the company's marketing department will set up a dedicated data network automation maintenance team that will be responsible for the meter reading and maintenance of the automatic collection device. "When automatic coverage is fully covered, maintaining data quality will become a key point, and the management focus will also shift from metering device management to data acquisition management," said Li En, who specializes in marketing.

From manual meter reading to smart meter reading system to witness the changing times
[China Instrument Network Instrument Industry] At 9:00 on August 29, 2016, Ji Hongliang opened the measurement automation module of the marketing system. He gently clicked a mouse and the data of 165 power meters was all uploaded to the system within 30 seconds. It is the result of the changes in Foping Power Times.
