At 15:05 on January 12, 2022, Datang Anhui Luoneng Power Generation Co., Ltd. (hereinafter referred to as Datang Luohe) successfully completed the full-load trial operation of Unit 5 after comprehensive upgrading, marking the smooth operation of Unit 5 of Datang Luohe Power Plant after the transformation. Hollysys HOLLiAS MACS IC fully autonomous controllable DCS system has realized the first set of DCS+DEH integrated operation of ultra-supercritical thermal power units above 600MW, providing a model project for the localization transformation of large-scale thermal power units and setting an industry benchmark.
Promote the process of localization with innovative technology
Datang Luohe Unit 5 was put into operation in 2008 for power generation, using foreign DCS and DEH systems. This time, Hollysys HOLLiAS MACS IC completely autonomous and controllable DCS system was used to transform the No. 5 DCS system (including DEH and ETS) and the DCS public network of 5 and 6 units.
The total number of points of the project exceeds 30,000 points, and a total of 33 pairs of controllers are configured to complete the functions of DAS, MCS, SCS, FSSS, ECS, ETS, DEH and other functions of the unit. The project completed the factory acceptance on August 30, 2021; The on-site restoration was completed on September 25; On October 25, the public system was put into use; On November 26, it passed the on-site performance and function test of the expert group of the Power Generation Special Committee of the Chinese Society of Automation; The hydrostatic test was completed on December 8; Blowpipe completed on December 20; On January 4, the steam turbine impulse fixed speed was 3000 rpm; On January 8, the unit was connected to the grid; Finally, the full-load trial operation was completed on January 12.
Autonomous and controllable, safe and trustworthy HOLLiAS MACS IC DCS EFFICACY
Hollysys HOLLiAS MACS IC is an integrated management and control platform for industrial sites carrying DCS, SIS/CCS, PLC, SCADA, industrial software and other system functions, using ultra-large-scale system design, supporting up to 128 domain integration, a single domain up to 1.2 million points, 64 control stations, a single control station up to 360 IO configurations, and a system response time of < 30mS, which fully meets the high reliability and high safety requirements of ultra-large refining and chemical projects.
The system is the latest achievement of the deep integration of Hollysys' independent research and development of localized control technology and information security technology, and has the three characteristics of cross-platform, independent and controllable, safe and credible.
(1) The system software is all source-level cross-platform, and a set of software source code is adapted to the compilation and construction of a variety of operating systems, realizing cross-platform/cross-language data exchange, convenient deployment to different operating system platforms, and easy to upgrade and transform the existing system.
(2) Each system component adopts domestically produced components, the system software is independently developed based on the domestic operating system, and the platform adopts OT/IT deep integration technology to realize the integration of management and control. It can be said that the software and hardware of the system platform are independently controllable and produced in China.
(3) The main control unit of the system has a built-in independent trusted security protection system, which improves the technical level of trusted computing in the field of industrial embedded control, and is the first endogenous security DCS control system, and has a number of built-in security audit and data encryption algorithms to meet the requirements of the third level of information security protection.
The quality and efficiency have been improved, and it has been recognized by users
Since the establishment of the project, Hollysys has dispatched elite soldiers from various departments to form a project team. After it was put into operation, Hollysys system operated stably, safely and reliably, and was highly recognized by users. Datang Luohe Power Plant and the general contractor, East China Electric Power Design Institute, paid special tribute to Hollysys' high-quality product technology, and highly praised the project team's rigorous and responsible work attitude and excellent technical level. The successful application of Hollysys HOLLiAS MACS IC completely autonomous controllable DCS system in ultra-supercritical thermal power units above 600MW is the perfect coupling of chips, databases, operating systems, industrial software, automation technology and large-scale thermal power industry technology in the independent industrial field, which gets rid of the dependence of the core technology of domestic industrial control system on foreign countries, and solves the problems of supply chain security, information security, functional safety, and intrinsic safety in the traditional industrial control security application field. It has realized the upgrading and transformation of large-scale industrial control systems, improved the technical level of DCS control systems in the field of power generation in China, and is of great significance to ensure national energy security.
Hollysys will take this breakthrough as an important milestone in promoting the localization process, make unremitting innovation, boldly explore, empower the industry with independent, controllable, safe and credible products, technologies and solutions, help users achieve a significant improvement in engineering efficiency with an efficient and easy-to-use integrated platform, ensure the smooth operation of users' system equipment with digital services, and continue to escort the national industrial security.
