On the red hot soil of Liupan Mountain, a million kilowatt unit runs smoothly, delivering a continuous stream of clean electricity to this revolutionary old area. Recently, Unit 1 of the 2 × 1000 MW unit construction project of Ningxia Electric Power Liupanshan Power Plant, which China Power Construction Corporation participated in, successfully passed the 168 hour full load trial operation and officially entered commercial operation. The project has landed in Guyuan, filling the energy gap in southern Ningxia and injecting strong momentum into regional energy transformation and local development.

Precision construction ensures smooth operation of the unit

The Liupanshan Power Plant of Ningxia Electric Power is located in the revolutionary old area of Liupanshan in Guyuan City, Ningxia Hui Autonomous Region. It is the first typical demonstration project of two joint ventures with a capacity of one million kilowatts in China, developed and constructed by integrating coal and thermal power comprehensive energy supply. The project plans to construct two 1 million kilowatt high-efficiency ultra supercritical indirect air cooling units, with a new energy project configured in a ratio of 1:2, and synchronously equipped with desulfurization and denitrification devices, railway dedicated lines, and distributed photovoltaics.

China Electric Power Construction Corporation's subsidiary, Power Construction Nuclear Power Company, has been deeply involved in project construction, facing various technical difficulties in the installation of high parameter units, closely monitoring the welding quality control of key positions such as the four major pipelines of the boiler heating surface, strictly controlling the accuracy of equipment installation, system cleanliness, and construction standards of various key processes. It has successfully achieved multiple important milestones such as boiler water pressure test and generator rotor installation in one go, laying a solid foundation for the completion and operation of the project through high standard construction and high-quality performance.

Intelligent control collaborative support for new energy consumption

The project innovatively applies 20 to 100 domain adaptive intelligent cruise control technology for million kilowatt level units, which has the ability to deeply reduce load and quickly climb slopes, and can provide strong support for large-scale new energy grid integration and consumption in the region.

The project aims to create a full industry chain model that integrates coal and electricity, comprehensive energy, and intelligent operation. It can undertake the three core functions of regional power grid peak shaving, summer peak demand, and energy supply guarantee for local industries. It is a key project to support the construction of a 10 million kilowatt level thermal power base in Ningxia and serve the creation of a new power system demonstration zone. The joint venture of coal-fired power and new energy is not only a practical choice to ensure supply and stable prices, but also a long-term path to promote the transformation of coal-fired power and achieve the synergy and complementarity between traditional energy and new energy.

Green diversity drives the revitalization of industries in old areas

The project innovates the utilization of water resources by regularly using the standard tail water from the urban sewage treatment plant in Guyuan City as the main source of production. It can consume 4.1 million cubic meters of recycled water annually, fully activating recycled water resources and effectively alleviating the regional water resource shortage. The railway dedicated line built as a supporting project will open up the logistics channel of Guyuan New Materials Industrial Park, and the project will also have the ability to provide industrial steam and centralized heating for people's livelihoods, promoting the on-site transformation and value-added of regional coal resources.

After the project is fully put into operation, the annual power generation capacity can reach 10 billion kilowatt hours, filling the gaps in Ningxia's energy layout from the north to the south, becoming a backbone supporting power source in southern Ningxia, continuously optimizing the regional energy structure, driving the steady progress of local economy, and accelerating the transformation of coal-fired power to basic guarantee and system regulation power sources.Editor/Huang jiali
