ã€Industry Focus in China's Instrumentation Network Industry】 In 2015, Lijiang Bureau vigorously promoted the use of the metering four-in-one system, gradually improved the meter reading coverage rate, gradually improved the power meter reading, electricity data statistics input, long accounting cycle, and four points of line loss. Management issues such as lack of real-time data.
In January 2016, just a mouse click on the computer, the Gucheng Power Supply Bureau made a copy of the electricity in the township in December (statistics). The meter reading work that took 15 days to complete was shortened to 1 day. Solved the problem of meter reading that has been plaguing power supply for many years. Originally, in December 2015, a large power supply station realized the full coverage of the low-voltage collection in the township's entire rural area, which provided experience for advancing the development of the global metering four-in-one system.
The original meter reading can be so convenient Lijiang Power Supply Bureau most of the power supply area for the power supply area is a mountainous area, Shangao Road, a single line power supply radius, users scattered, to the power supply meter reading has brought great difficulties, a long period of meter reading every month In addition to the long meter reading period, there are still inaccurate meter readings, estimated copying, missed copying, and long battery data entry time. There is a lack of real-time supervision of power supply data, and users can only confirm the cause of the failure at the site and repair it is not timely. It is even more difficult to grasp the real conditions of line and station line loss, and these problems can all be solved by measuring the four-in-one system.
The metering four-in-one system is a system that combines the four functions of electric energy collection, distribution transformer monitoring, electric power load management, and low-pressure collection. By advancing the construction of a metering automation system, the power supply station can accomplish meter reading without leaving the house. With a click of a mouse, meter reading can be completed, completely eliminating missed copying, estimated copying, and realizing various data. Sex and timeliness are guaranteed.
On January 8th, in a large power supply station, the deputy director of the deputy director and Akihito skillfully entered the metering four-in-one system. After confirming that the value of the copied data is normal, “click on the batch remotely, all the users in the township The meter power is displayed, and the electricity data derived from the four-in-one system is measured. After checking, the data is imported into the marketing system and the meter reading task is completed within one month of the township. The previous 15 days are copied. Table work is now completed in one day."
For the benefits of low-pressure collections, it is also a great experience for both the director of power supply and Shih Yuan. “Our farthest station area is from Daguzitai District, Maoniuping, which is 30 kilometers away. There are only 2 users and the electricity consumption is about 60 degrees every month. Before, it would take three hours to copy one time table back and forth. Now On the computer, solving the meter reading problem will save time and effort."
“Although the low-pressure collection has been fully covered by townships, there is no need to go out to read the meter, but it is still necessary to regularly check the accuracy of the electricity on the spot.†He Ping said. Now, the accuracy of meter reading by large power supply stations is above 99%. However, in order to ensure the accuracy of the meter, the power supply institute has established a low-pressure meter reading meter inspection plan, and a certain percentage of the total number of meter counts will be checked on site every month. Degrees, all users in each zone will have one onsite inspection once a year.
Meter reading has a quick and accurate solution, and all of the power supply is devoted to standardization and customer service.
The powerful metering four-in-one system has more powerful functions than the meter reading and metering four-in-one system. "We can now do more things in the metering four-in-one system." He Shiyuan said that after the low-voltage data collection was fully covered, remote control of low-voltage users was realized, which reduced the delay due to arrears. The amount of work for the restoration of electricity and the supply of electricity can also put time into the work of recovering electricity charges, and gradually cultivate the user's good payment habits. In 2015, the Power Supply Institute achieved monthly electricity bills and annual zero, and the non-cash contribution ratio in the fourth quarter reached 79%.
In the past, the power supply station had to suffer from line loss management every month. Because there was no effective and accurate data, especially in low-voltage stations, line loss management has always been a difficult problem. Now, the line loss of each line and the station area is clear at a glance. At the same time, the previous error caused by the difference in meter reading time to the line loss calculation is avoided. "Because it takes a certain amount of time to read a meter in a Taiwan area, after reading the meter and copying the total, there will always be a time difference, resulting in inaccurate line loss management data. You can now view the line loss in real time." It said that real-time and accurate data provide effective support for line loss management, and it also provides effective technical means for analyzing abnormal line losses and reducing line losses.
"After the user fails to repair the report, unless the main line trips, it is only at the scene that the cause of the failure can be checked and the time for resuming the power is difficult to control." He Shiyuan said that because it was impossible to determine the cause of the failure, the power supply would spend a lot of time looking for failure points. The recovery time is longer. "By measuring the four-in-one system, we can basically judge which line, station area, or a single user has blackouts." Shih says that especially if only one user loses power, it can still pass The phone allows the user to see if it is an open trip, which greatly reduces the inspection time and improves the efficiency of repairs.
The metering four-in-one system can also monitor current, voltage, and load. If there are overloaded lines and equipment, load transfer can be performed in time. At the same time, it can also provide powerful data protection for power grid reconstruction.
The power supply station autonomously installed the meter to increase the speed and set the whole township to cover the entire area. The power supply station is located in the north of the Yulong Naxi Autonomous County. It is beside the Yulong Snow Mountain, beside the Jinsha River, and is 89 kilometers away from the county seat. It has 14 employees and an average age of 30 years. A total of 3,952 households of 9 village committees in Dayou Township and Mingyin Town provided electricity supply services. The villagers’ group had 163 distribution transformers and the distribution line covered an area of ​​785.3 square kilometers.
There are 2019 households in the township of Daju Township. In 2014, when the rural network was rebuilt, 1,680 carrier watch replacements were implemented. In 2015, 134 power supply meters were independently replaced, and all meters were checked, all of which were in measurement One system maintenance.
In accordance with the work requirements of the “Cultivating Year for Collecting and Copyingâ€, in accordance with the work idea of ​​“Reconstruction and Transformation of Township Power Supply Stations with County and District Power Supply Bureaus as the Main Bodyâ€, in order to give full play to the role of fighting fortresses and vanguard models, the township and township power supply institutions in the area are promoted. Copying and reforming work promoted effectively and achieved substantial results. The Party General Branch of the Gucheng Power Supply Bureau responded quickly and took active actions, and established the “Party Commando†with the Party branch secretary as the leader, the deputy chief of the Party branch, and the deputy leader. And encourage the majority of young employees to set up a “Young Assault Teamâ€. In December 2015, they went to Dazhai Township to carry out the work of copying, transformation and assistance. Through commando team assistance, a total of 121 watches were replaced. After the raid, Daju Township set a copy rate of 96%. On December 31st, Daju Township set a copy coverage rate of 100%.
The large power supply station not only installed the meter reading meter independently, but also managed the power supply station. All employees of the power supply station can go on pole operations. In 2015, the 10kV line in the area under its jurisdiction was subject to structural barrier removal and hidden trouble investigation. The construction of a standardized and harmonious power supply station for power supply stations was effectively promoted. In 2016, a large power supply station will focus on completing the 400-volt line survey work, and will focus on sounding the sound to promote full coverage of the copy. At the same time, it will strengthen the internal management of the power supply base, effectively improve the reliability of power supply, and increase customer satisfaction.
On January 8, 2016, in order to rapidly promote Lijiang Bureau's information integration and measurement of "Four-in-one" system construction, leaders of 7 bureaus, offices, marketing department, measurement center, heads of Gucheng and Yulong Power Supply Bureau came to the The power supply station carried out special information training and on-site observation of information integration and measurement of "Four-in-one" construction. At the meeting, the marketing department introduced the Lijiang Bureau's application of information integration in construction, and the Gucheng and Yulong Power Supply Bureau introduced the application of information integration construction in the Bureau and the measurement of the four-in-one application of the terminal. The measurement center conducted a four-in-one system for measurement. Using training, the participants also visited and researched the construction site of the four-in-one station terminal, the negative control terminal, and the distribution transformer terminal where the power supply station was measured.
In 2015, Lijiang Power Supply Bureau had 133 power plants and substations, 1986 special-purpose users, 2016 public transformer station areas, and 17289 low-voltage residential users realized terminal coverage, realizing straight-to-driving and direct-control area stations, special transformers, and public transformers. cover.
