The "Yangtze River Delta Integrated Electricity Conservation Affairs Agreement Agreement" played a role in Zhejiang Jiashan Economic distribution network contact line from Shanghai Qingpu

"Hello, I am Jiashan to schedule Gaoli." "Hello, I am Qingpu to dispatch Liu Chao." "Due to sudden failures, the line after Jiashan 10 kV Yuhui changed the line of Qingpu." "Received!" At 12:28 on August 13th, the 10 kV Bare line of the 35 -kV Yuhui transformation station in Jiashan County, Zhejiang Province failed.

Since the summer, the Yangtze River Delta has encountered large -scale continuous high -temperature weather. In order to ensure that the normal power consumption company does not affect the normal power consumption of the residents when the failure is eliminated, Jiashan County Power Supply Company immediately contacted the Shanghai Qingpu Power Supply Company and decided to follow the "Yangtze River Delta Integrated Power Supply Aid Agreement". The power of electricity is transferred to Jiashan to ensure that the power supply is sustainable and reliable.

Jiashan County Power Supply Company Xitang Power Supply Station's operation and maintenance professional employees and employees of substation operations and employees found that the fault point is located on the 10 kV Yure Line. Due to the continuous high temperature, the number of rods on the 4th to 5th on this line is perpendicular to the arc. Decrease, discharge the lightning needles on the roof below, causing the line to ground, and it is necessary to repair it as soon as possible.

About half an hour later, the employees of the operation and maintenance company of Jiashan County Power Supply Company and Qingpu Power Supply Company arrived at the scene. With the inter -provincial distribution line, Jiashan -Qingpu No. 1 contact switch was changed to operating status, customers in Yuhui District, Jiashan County Power on the 35 -kilovolt Liteang substation from Shanghai. After more than 4 hours of repair, employees of Jiashan County Power Supply Company eliminated the bus failure at 16:50 and restored the power supply. On the same day, the 30 public transformers and nearly 900 special transformers of the 10 kV Yuhui Line of Jiashan County, nearly 900 customers of nearly 900 customers, supported Jiashan County's electricity volume of 1900 kWh. This is the first time that the "Yangtze River Delta Integrated Electric Power Supply Agreement Agreement" has been signed since the signing of the mutual aid agreement of the 10 kV inter -provincial distribution network.

On June 23, Qingpu District, Shanghai, Wujiang District, Suzhou City, Jiangsu Province, and Power Supply Company, Wujiang District, Zhejiang Province, signed the "Yangtze River Delta Integrated Electric Power Supply Aid Agreement" to clearly use power to protect the primary goal and integrate all parties to all parties. In the aspects of the operation management, maintenance and maintenance of the power grid facilities, maintenance and maintenance, fault repair, emergency linkage, etc., establish a model of "interconnection, interoperability, mutual protection, mutual preparation, and mutual preparation", and the full capacity supports the protection work, increasing the grid of the grid of the grid frame , Improve the level of power supply services and ensure the power supply of the three places.

After the signing of the mutual assistance agreement, Jiashan County Power Supply Company used the 10 -kilovolt interchanged distribution network connection line built in 2019 to carry out power access work. "Under the regular operation method, the 35 kV Yuhui transformation station of Jiashan was powered by the Jiashan 35 KV Shanyu Line." According to Huang Quanfei, the director of the Power Schedule Control Sub -Center of Jiashan County Power Supply Company, since the signing of the agreement, the Yuhui transformation power station was mainly built by the previously built before. Qingpu 35 kV Qianyu line is powered by the 10 kV level.

Qingpu Power Supply Company first tour the related equipment for inter -provincial contact lines of the three places after the agreement was signed.

"From the signing of the agreement until August 21, we passed the 35 -kilovolt Ganshu Line and the 10 kV inter -provincial distribution network contact line to confess a total of 6.7259 million kilowatt -hours of electricity to ensure that the residents at the junction of the two places under the junction of the two places were guaranteed. The company's normal life production electricity. "Yang Guojian, director of the Electric Power Schedule and Control Center of Qingpu Power Supply Company, introduced.

In order to do a good job in the peak summer power guarantee, the load prediction information of Qingwu Jialiang Power Supply Company is more closely connected, which has improved mutual supply efficiency. By establishing a cross -regional emergency contact mechanism, the three places power supply companies have also realized the ability to share emergency resources information and complement each other, and further enhance the ability to deal with the fault of integration.
