On May 11, 2024, the DCS autonomous controllable transformation project of Unit 9 of Datang Toktor Power Plant successfully passed 168 hours of trial operation and successfully completed the operation. Hangzhou Hollysys Automation Co., LTD. (hereinafter referred to as: Hollysys) provided the HOLLiAS MACS IC fully autonomous controllable DCS system for the project, and the software and hardware realized 100% localization. The independent and controllable transformation of the project has become an important demonstration benchmark for stable production and supply in the Beijing-Tianjin-Hebei region, and comprehensively guarantees the essential security of major national energy sources.

DS200TCPDG1BEC The project department of Hollysys has been unanimously recognized by the owners for its spirit of performance and technical ability in the implementation process, and has received the “excellent project” banner awarded by the owners, as well as the trophies of “Quality supplier” and “excellent engineering team”, demonstrating the company’s professional engineering strength and first-class service level.

The state is as important as Japan

Datang Toktor Power Plant is located in Toktor County, Hohhot City, Inner Mongolia. It is the largest thermal power plant in the world with 10 units of 600,000 units and 2 units of 300,000 units. As the first 600,000-kilowatt ultra-supercritical unit in the plant, the independent and controllable transformation of Unit 9 is the most crucial part of the transformation of 24 units in the Beijing-Tianjin-Hebei guaranteed supply area of Datang Group. The successful transformation of the project has an important demonstration significance in Datang Group and even in the power industry.

Domestic transformation and intelligent upgrading are the fundamental needs of Datang Toktor Power Plant. The 660MW unit No. 9 of the thermal power plant was put into production in 2016. The original DCS, DEH, MEH, ETS, METS and other systems are all branded by foreign manufacturers, and their independent controllable transformation time is tight, the task is heavy, and the construction complexity is high and difficult.

China Wisdom building unswervingly

DS200TCPDG1BEC In order to ensure the smooth implementation of the domestic transformation of DCS of Unit 9 and start the first shot of the domestic transformation of the Great Tang Beijing-Tianjin-Hebei Guarantee project, Hollis attaches great importance to the project, effectively organizes and coordinates the company’s superior resources and sets up a major project team. In the design, supply, in-plant testing, on-site construction, transmission commissioning and other links, with high standards, high quality, high efficiency to promote the smooth implementation of the project.

The project adopts HOLLiAS MACS IC fully autonomous controllable DCS system independently developed by Hollysys, with 100% localization of software and hardware, a total of 38 pairs of controllers, 84 control cabinets, 15,160 I/O measuring points, including DCS/DEH/ETS/MEH/METS system. The transformation of the factory-level public system has solved the strategic problem of autonomy and controllability of the current major equipment, and laid a solid foundation for Datang Group to accelerate the construction of energy security and achieve high-quality development.

In the future, Hollysys will vigorously promote the comprehensive application of independent innovation technology in key energy fields such as power, petrochemical, metallurgy, and strive to build first-class demonstration benchmarking projects, and provide strong support for the localization and intelligent development of China’s major equipment. With the fire of science and technology, build the soul of a powerful country!
