On December 11, at the 10 kV Jinghua Shijia Distribution Station in the Jinghua Shijia community in Baohe District of Hefei, employees from the Baohe Power Supply Branch of the State Grid Hefei Power Supply Company conducted special equipment inspections. Recently, the new construction of the Jinghua Shijia Distribution Station stood out, winning the "Top 100 Projects" for distribution network engineering quality from the State Grid Corporation for 2024, making it the only selected distribution station project in Anhui Province this time.

At the Jinghua Shijia Distribution Station, two robots automatically inspect the power equipment and perform infrared temperature measurements on the rooftop rails and the ground. The station is equipped with smoke detectors, temperature and humidity sensors, and conducts continuous, comprehensive monitoring without blind spots, 24 hours a day.

"This station is a smart station. Robots and sensors automatically complete routine inspections, transmitting information to the platform via a 4G wireless private network for intelligent analysis," said Feng Wei, project manager of the power supply service command center at Hefei Power Supply Company. "If any environmental anomalies or intrusions occur, the platform immediately triggers an alarm and sends a work order to the device owner's mobile phone. The station is equipped with a distribution automation system that can automatically isolate faulty equipment in seconds."

The Hefei Power Supply Company built the Jinghua Shijia Distribution Station according to the new generation Smart Station standards set by the State Grid Corporation. The station's distribution transformer capacity is 2000 kVA, using advanced domestic power equipment, and is equipped with distribution automation functions. The reliability of the 10 kV Jinghua Shijia Distribution Station's power supply reaches 99.999%, with a voltage qualification rate of 100%.

"Currently, there are 3,744 distribution stations in Hefei, with smart stations accounting for about 19.93%," said Zhu Jian, deputy director of the Smart Distribution Network Department at Hefei Power Supply Company. He stated plans to incorporate distribution network engineering construction into Hefei's "Major Construction" system through a "government-enterprise collaboration" model, aiming to promote the planning and construction of new distribution stations more efficiently and to higher standards, continually enhancing the reliability of the distribution network.
