Project Background and Significance
The Dunhuang 35kV power transmission and transformation project is a key energy project in Gansu Province's 14th Five-Year Plan, with a total investment exceeding 200 million yuan. The project plans to construct a new 35kV intelligent substation and supporting transmission lines, covering Dunhuang City and surrounding desert photovoltaic parks, with an annual green electricity transmission capacity of 320 million kilowatt-hours. The project aims to strengthen Dunhuang's power grid structure, support the development of local new energy industries, and provide a strategic foothold for energy interconnection along the Belt and Road Initiative.
Shanghai Zikai Electric Co., Ltd., as the core power distribution equipment supplier and technical service provider, provided a complete set of intelligent power distribution solutions for the project and participated in the entire process of system commissioning and power transmission, helping Dunhuang build a safe, efficient and low-carbon energy supply system.
Project Highlights and Contributions of Zikai Electric
High-reliability desert smart substation
In response to the unique environment of Dunhuang, characterized by extreme drought, large temperature differences between day and night, and wind and sand erosion, Zikai Electric designed a fully sealed GIS combined electrical appliance + intelligent circuit breaker architecture, with equipment protection level reaching IP65 and key component lifespan extended to more than 25 years.
A digital protection and control system is adopted to achieve millisecond-level fault location and automatic isolation, ensuring the stable operation of photovoltaic grid connection and power grid.
Intelligent monitoring and green electricity traceability
An integrated IoT monitoring platform monitors equipment status, power quality, and renewable energy consumption in real time. It also enables green electricity traceability through blockchain technology, supporting Dunhuang in building a "zero-carbon city" brand.
It reserves access ports for energy storage systems, which can be expanded to frequency regulation auxiliary services in the future to improve grid stability.
Adaptability to harsh environments
The equipment has passed sandstorm environment testing and certification, and can withstand extreme climates with PM2.5 concentrations exceeding 5000μg/m³, ensuring long-term stable operation in the Gobi Desert.
Strictly adhere to State Grid's technical specifications, support the implementation of the "West-to-East Power Transmission" strategy, and help transmit Dunhuang's green electricity to North and Central China.
Customer testimonials and regional value
The head of Dunhuang Energy Investment Group stated, "Zikai Electric's intelligent substation not only far exceeded expectations in terms of technological advancement, but its professional team also collaborated efficiently throughout the entire process, from scheme design to power transmission implementation, fully guaranteeing the project's progress and quality. This cooperation has laid a solid foundation for Dunhuang's strategic position in the new energy era!"
The successful power transmission of this project marks a significant step forward for Gansu Province in the integrated development of "desert photovoltaic power + smart grid," providing a replicable solution for the construction of new energy bases in Northwest China.
Zikai Electric: Lighting Up the Silk Road with Green Electricity
