Zhejiang's first multi -source collaborative mountain distribution network opened in Taishun

"Successful investment!" At 10 am on August 16th, the dispatching hall of Power Supply Company of Tai Shun County, Guonet, accompanied by the resounding of the dispatcher's resounding, marked the official in Zhejiang's first multi -source coordinated mountain distribution network. Shunzun production is enabled.

Taishun is located in the mountainous area of ​​Zhejiang, and 90%of the territory are covered by mountains. There are problems such as weak power grid structure and low anti -interference ability in power supply lines. Located in Nanpuxi Town, which is located in the northern Mountains of Taishun, more than 20 villages only rely on a 50 -kilometer -long lifeline to ensure electricity consumption. When natural disasters such as typhoons and lightning strikes, the safety of electricity in mountainous residents is difficult to obtain stable guarantee. To build a 35 -kilovolt power station in mountainous areas, it costs nearly 50 million yuan, and the construction is difficult and the cycle is long.

"The data shows that the number of power outages in the Shinpo G973 line in the past three years is as many as 63 times, and the maximum failure of the fault repair is up to 11 hours, and the average repair time is about 2 hours, which affects the normal power consumption of residents." Manager Zhang Zhijun said. How to ensure the stability of the end of the mountain area into a heart disease of Taishun Electric Power.

Although the average annual power generation of the Taishun Small Hydropower Station exceeds 600 million kilowatt hours, they are concentrated in remote mountainous areas and are at the end of the distribution network line. Limited to the superior power supply points and high costs. This part of the distribution grid line is basically no connection, and the reliability of power supply is difficult to guarantee. To this end, Taishun proposed to build a multi -source coordinated mountain distribution network, which overlap the 10 kV home line of 35 kV rising stations with the distribution line, so that the electric power "copy the small road" from the hydropower station to the user to solve the solution With weak issues such as network racks.

Liu Yingying, the person in charge of the project, said that the project integrates a large number of "black technology" and is equipped with new products such as "4G+quantum" switch and "smart cabinet". When the grid fails, the switch is automatically closed to achieve the "second -level" re -power of the line. Taking the Xinpu G973 line as an example, once a power failure failure occurs, the liaison line of the hydropower station can directly supply power to residents to avoid the impact of power outages on residents.

At present, the company has successively built a demonstration project in two multi-source collaborative power distribution networks in Yangtze-Diqian and Longnan-Xiao Village. Compared with traditional projects, this project only invests only 500,000 yuan in funds, which not only solves the problem of weakness in remote mountain racks, but also saves a large number of artificial operation and maintenance costs, which can still run stably under extreme conditions.

"In addition to saving costs and improving power supply reliability, the project has also greatly improved energy from balanced and eliminating." Zhang Zhijun added. As a typical energy area, Taishun County is delivered to one -sixth of the electrical energy loss caused by a large amount of hydropower. And the multi -source coordinated mountain distribution network breaks through the method of long -distance transportation power from traditional hydropower stations, and achieves clean energy and local balance. According to estimates, a single project can reduce the energy loss of 50,000 kilowatt -hours per year, which is equivalent to 20 years of electricity consumed by residents of one mountain area. In the context of structural lack of electricity in the province, the investment operation of the multi -source collaborative distribution network is of great significance.

Standing at the foot of the mountains, the small water power stations laid between the mountains are like "high mountain pearls", more like the seeds sprinkled between the green mountains and green mountains. Serving the development of energy green and low -carbon transformation is ready to go. (Correspondent Wang Fuxuan Bao Shu Jingxian quietly)
