In the Dongxing area of Dongjiang High-tech Industrial Park in Zhongkai High-tech Zone, the construction site of Guangdong Huadian Huizhou Dongjiang Gas Turbine Thermal Power Project (hereinafter referred to as "Huadian Dongjiang Project") is lined with tower cranes, and all kinds of construction machinery are working at full capacity, showing a hot construction scene. The project is a key project of Guangdong Province's "14th Five-Year Plan" energy development plan to ensure power supply and a provincial key engineering construction project, and plans to build two 535MW gas-steam combined cycle cogeneration units (supporting the construction of heating and cold pipe networks).

"So far, about 70% of the investment in the project has been completed, and it has entered the stage of equipment installation and commissioning, and will be put into operation by the end of this year. Liu Xiaodong, chairman of Guangdong Huadian Huizhou Energy Co., Ltd., said that the project will build the first benchmark 9F5 gas turbine digital power plant with high localization rate in China, helping to improve the energy security capacity of the Guangdong-Hong Kong-Macao Greater Bay Area and the adjustment of Huizhou's energy structure.
The heavy-duty gas turbine is known as the jewel in the crown of industry, its operating conditions are harsh, involving complex disciplines, and it is extremely difficult to develop and develop, and it is one of the key equipment that is "stuck" in the mainland. It is understood that Huadian Dongjiang project plans to build 2 sets of F-class heavy-duty gas turbine units, with a localization rate of up to 85%.

"The project is currently built with the largest output and the highest efficiency of the F-class gas turbine M701F5 in China, with a single combined cycle machine assembly capacity of 535MW. Liu Xiaodong introduced that the model has made a number of technological breakthroughs in multi-stack cylinder block welding, compressor static blade grid welding, large-scale cylinder block parts processing and control deformation, and gas turbine digital assembly, reaching the advanced level in the industry.
On February 27 last year, the main project of Huadian Dongjiang Project started construction, and at the end of November of the same year, the lower cylinder of the first M701F5 gas turbine in China was successfully hoisted into place. On April 9 this year, the intelligent distributed control system (ICS) of Unit 1 of the project was successfully restored to a time, marking the transformation of the project from static installation to dynamic commissioning.
At present, Huadian Dongjiang Project is steadily promoting the installation and commissioning of equipment, and strives to achieve the commissioning of two sets of units by the end of this year.
In order to match the high parameters of the gas turbine and make more efficient use of the waste heat of the gas turbine, the waste heat boiler and supporting steam turbine used by the units of Huadian Dongjiang Project will realize the combined cooling, heating and power supply after completion. "The electricity generated is directly integrated into the 220KV Lujiang Station, and the high-quality steam and cold water generated by the waste heat will also meet the production needs of Dongjiang High-tech Industrial Park and its nearby enterprises, help improve the energy security capacity of the Guangdong-Hong Kong-Macao Greater Bay Area and the adjustment of Huizhou's energy structure, and promote energy conservation, emission reduction and efficient use of energy. Liu Xiaodong said that as a clean energy, Huadian Dongjiang project will contribute to the realization of the "double carbon" goal of the province and the city.

It is worth noting that, as a backbone power supply construction project in Guangdong Province, Huadian Dongjiang Project has actively embraced the wave of digital power transformation from the beginning of its establishment, and will build the first 9F5 gas turbine digital power plant with high localization rate in China.
On April 9, the intelligent distributed control system (ICS), which was successfully restored to power, is the key to the construction of a digital power plant. Liu Xiaodong introduced that the project will integrate the application of the first set of localized ICS system. With the help of this system, the project will apply 5G, Internet of Things, blockchain and other technologies, and use intelligent control and intelligent inspection robots to achieve efficient grasp and early prediction of the status of the unit, greatly improve the labor productivity of all employees, and build the project into a benchmark digital power plant in China.
"The digital power plant is a bold exploration of China Huadian's power projects, and it is also a concrete embodiment of new quality productivity. Liu Xiaodong said that next, Guangdong Huadian Huizhou Energy Co., Ltd. will further deepen scientific and technological innovation, strengthen joint research, build China Huadian's first ICS intelligent distributed control system project, and strive to form a number of scientific and technological achievements with independent intellectual property rights to realize the automation, informatization and intelligence of the power production process.
