KUITUN, China, December 31, 2024 /PRNewswire/ — On December 30At the 220 kilovolt substation of Kuitun East Industrial Park, operation and maintenance personnel of the State Grid Kuitun Power Supply Company were carrying out a comprehensive inspection of the newly commissioned substation. Using methods such as infrared temperature measurement, they monitored the operating status of the equipment in real time, making every effort to ensure the safe and stable operation of the new substation after it was put into operation and providing a strong energy guarantee for regional economic development.
Since the beginning of this year, the company has carefully implemented the State Grid Corporation’s deployment of China on accelerating the construction of a modern equipment management system. Adhering to the principle of “safety first” and following the work philosophy of “reliability, standardization, efficiency and economy”, it vigorously promoted the implementation of “two replacements” construction and gradually advanced the “control sequential in one click. transformation. So far, 21 of the company’s substations meet the operating conditions for one-click sequential control.
One-click sequential control technology is an innovative achievement based on the automation system. In traditional switching operations, operation and maintenance personnel need to go to the site or operate manually in the main control room according to the operation ticket steps. However, new technology allows traditional manual switching operation procedures to be pre-entered into the computer. With a single click of the “one-click sequential control” command, the “one-click sequential control” conversion of the three states of “cold standby, hot standby and running” of the main equipment of the substation can be achieved, saving more than 50% of manual operation time. When preparing “one-click sequential control” operation tickets this time, Kuitun company innovatively integrated key elements such as anti-malfunction checking of equipment status and inspection of the state of the protection devices. It not only accurately checked the working status of the equipment, but also integrated the on/off state of the pressure plate of the protection device and the alarm information of the device into the locking logic of the sequential control operations, truly realizing “machines replacing laborious tasks and numbers driving intelligent operations.”
On December 26while the centralized control personnel clicked the “Run” button of the “one-click sequential control” operation interface, the No. 1 and No. 2 main transformers of the Kuitun East 220 Industrial Park substation kilovolts were officially put into operation with electricity. As the first substation of Kuitun Company to use “one-click sequential control” for power transmission, the company organized a professional technical team to form a special team. They conducted numerous technical discussions and formulated work plans, effectively managing various aspects such as safety, quality and progress, and effectively completed a series of tasks to improve the “one-click sequential control” system. station side.
This power transmission operation required 81 hours to safely and efficiently complete a total of 6,300 operations, phase checks, load tests and other tasks in accordance with provincial and local power grid dispatch orders. “The commissioning of the substation was shortened from six days initially to three days and nine hours. The safety and accuracy of operation were significantly improved and the risk of malfunction was virtually eliminated,” explained Jin Xiaofengthe head of the centralized control station of the Substation Operation and Maintenance Center of the State Grid Kuitun Power Supply Company.
So far, the company has used “one-click sequential control” to perform switching operations a total of 243 times. The efficiency of switching operations has been increased by approximately 60%, achieving “fast, precise and stable” switching operations. This effectively reduced the workload of operation and maintenance personnel and further guaranteed their personal safety.
