On September 19,MK socks State Grid Aksu Power Supply Company successfully achieved, for the first time, the one-click "full stop and full turn" of the entire 110 kV Sunshine distribution network load through power distribution automation. The successful application of this technology will elevate the practical level of distribution automation in the Aksu region to new heights.

The one-click "all-stop-all-turn" technology for the entire distribution network load station refers to a sequence control technology that enables one-click initiation and sequential execution of batch distribution network switch operations. The application of this technology is of great significance for improving power supply reliability, optimizing power system operation, and improving customers' electricity experience.
It has been reported that the traditional load transfer method for the whole station often involves complex processes and lengthy operations for transferring the distribution network load of four 10kV lines. The conventional on-site load transfer requires 8 operating points and 16 people, with simultaneous operations taking at least 30 minutes, which not only increases operational risk, but also negatively impacts on the user experience. However, by utilizing the one-click "full stop and full switch" technology for the entire distribution network load, four 10 kV lines can be operated through a single power adjustment and switching action. It only takes 1 minute to achieve "full stop and full rotation" of the entire station's distribution network load, an approach that greatly improves work efficiency and reduces operational risks.
To successfully complete this load transfer work, State Grid Aksu Power Supply Company planned and prepared in advance, organizing coordination among various disciplines, such as dispatching, mode, protection, automation, and local county companies. They conducted on-site terminal location verification, remote control preset, switch status verification, and remote signaling checks to ensure the smooth completion of the one-click "full stop and full turn" task for the 110 kV Sunshine Transformation and Distribution Network Load Station.
The successful application of this technology not only enhances the "zero perception" of customers' electricity consumption during operations, improving their overall electricity experience, but also paves the way for Aksu's distribution network to quickly adjust and cope with large-scale maintenance operations.
Next, State Grid Aksu Power Supply Company will continue to promote the functional innovation and construction of the distribution automation master station system. They will keep promoting the one-click "all-stop-all-turn" working method, achieve lean dispatching empowerment through automated means, and continue to pursue high-quality development to meet people's electricity needs for a better life.
