The first unit of the country's first million-kilowatt "two joint venture" demonstration project was put into operation in Guyuan, Ningxia

China News Service, Guyuan, October 30 (Reporter Li Peishan) On October 30, Unit 1 of the Liupanshan Power Plant of Ningxia Electric Power Company of the National Energy Group successfully passed the 168-hour full-load trial operation and was officially put into commercial operation. This is China's first typical demonstration project of "two joint ventures" of one million kilowatts of coal power and coal, coal power and new energy, marking a key breakthrough in the construction of Ningxia's new comprehensive energy base.

The project is located in Guyuan, the old revolutionary base of Liupan Mountain. It is the only energy integration project of National Energy Group in Ningxia that integrates coal, thermal power and comprehensive energy supply. The overall plan of the project is to build two million-kilowatt high-efficiency ultra-supercritical units, supporting 4 million kilowatts of new photovoltaic energy projects, an annual output of 4 million tons of coal mines, and dedicated railway lines, building a development model of "coal and electricity integration, new and old energy complementation" to help coal and electricity transform from traditional power supply to two-way functions of guaranteed supply and peak regulation.

Relying on a number of industry-first technologies, this project sets a new benchmark for green and intelligent construction of million-kilowatt units. For the first time, the project applies global adaptive intelligent cruise control technology for million-kilowatt units, which has deep load reduction and rapid ramp-up capabilities, and can efficiently adapt to the needs of large-scale new energy grid connection and consumption. At the same time, the project implemented innovative technologies such as China's first million-kilowatt single-shell hyperbolic steel structure indirect air cooling tower, new high-efficiency plasma ignition, Beidou + laser precision measurement and intelligent monitoring, which greatly improved the energy-saving, flexible and safe operation level of the unit.

In terms of green development in arid areas, the project explores new ways to save water and increase efficiency. The factory achieves zero discharge of production wastewater and consumes 4.1 million cubic meters of recycled water from Guyuan Urban Sewage Treatment Plant every year; all construction solid waste is recycled and utilized to minimize ecological impact. Relying on the smart power plant system, the project uses the Internet of Things and 5G visual management and control to achieve less-manned and intelligent operation and maintenance, ensuring safe and economical operation of the unit.

The commissioning of this unit has effectively made up for the shortcomings of Ningxia's energy layout, which is "heavy in the north and light in the south", and has become the backbone supporting power source in southern Ningxia. The project not only undertakes the tasks of ensuring regional supply during summer peaks, ensuring industrial energy consumption, and stabilizing peak shaving of the power grid, it can also provide industrial steam supply and centralized heating services for people's livelihood, promote the on-site conversion of local coal resources, open up regional industrial logistics channels, transform the resource advantages of old areas into industrial development advantages, and inject strong momentum into the revitalization of revolutionary old areas.
