Recently, Keyuan Smart successfully won the bid for the project of two 600MW 9H-level gas-steam combined cycle thermoelectric cooling joint production project of Guangdong Yuedian Daya Bay Comprehensive Energy Co., Ltd.
This is another major breakthrough in the national production of DCS system NT6000 in the gas-steam combined cycle unit control system after projects such as Huadu, Yong'an, Binhai Bay. In addition, before this, Keyuan has won the bid for the smart construction site project of the project, providing it with comprehensive and intelligent control during the infrastructure period.
Guangdong Yuedian Daya Bay Comprehensive Energy Station is located in Daya Bay Petrochemical District, Huizhou City, Guangdong Province. It plans to build a 4×600MW grade gas-steam combined cycle thermoelectric cooling unit. This period, it will build a 2×600MW (H-class) gas-steam combined cycle cogeneration unit. It is the first integrated comprehensive energy demonstration base in China that combines the utilization of hydrogen energy and . After the project is completed, the annual power generation will be about 4.7 billion kilowatt-hours and the heating capacity will be 11.12 million kog. It will effectively improve the power support capacity of Huizhou City, meet the heat load demand in the western part of Daya Bay Petrochemical Zone, and at the same time absorb the combustible hydrogen-containing exhaust gas generated by major surrounding projects, improve the comprehensive utilization rate of energy, and explore and lead the new model of comprehensive energy supply in the Guangdong-Hong Kong-Macao Greater Bay Area.
All DCSs of the energy station use NT6000 intelligent control system and are equipped with field bus. At the same time, a unified production data processing platform has been deployed to achieve automated control of the entire range and process to help the energy station operate safely and efficiently.
three highlights: creating a new model for 9H gas engine control
fieldbus system
fieldbus control system architecture is highly decentralized, the field control equipment adopts fully digital communication, has strong data processing, status analysis and fault self-diagnosis functions, and the system can diagnose the operating status of the equipment at any time. Greatly improve the integration and intelligence of field equipment, laying a good foundation for the implementation of digital power plants.
Intelligent Power Generation Platform
This project deploys a production real-time data unified processing platform based on the conventional DCS system to realize integrated centralized monitoring of the entire factory's machinery, electrical, furnace and public auxiliary systems. The five intelligent modules include "intelligent analysis", "intelligent control", "intelligent operation", "intelligent alarm" and "intelligent monitoring" to form an intelligent power generation platform, realizing control over the entire range and process, improving the automation control level of the unit, and greatly reducing the operation volume of operating personnel.
APS&FCB
Gas-steam combined cycle generator set has the characteristics of high efficiency and environmental protection. Its rapid start-stop capability has outstanding advantages in peak shaving of the power grid and natural gas pipeline network. This project is equipped with two functions: APS (automatic start-stop control system for power plants) and FCB (fast load-shelving unit to factory power consumption). APS can minimize the start-stop time of the unit and respond to load scheduling of the power grid or natural gas pipeline network in a timely manner. In the event of a power grid outage, the FCB can "guarantee the power supply in the factory", which plays an important role in shortening the accident time of the power grid and reducing operating costs, with significant social benefits.
Smart Construction Site: Helps comprehensive intelligent management and control in the infrastructure period
In response to the complex site environment and many safety hazards in the power plant infrastructure period, Keyuan Smart makes full use of new technologies such as the Internet, artificial intelligence , intelligent AI and other new technologies to explore and successfully practice and apply them on the infrastructure period construction site. It successfully developed and implemented and put into operation of the smart construction site control system during the infrastructure period, empowering traditional power construction management and building a solid "safety Great Wall" for the safety management of the construction site during the infrastructure period.
In the future, Keyuan Intelligence will also use advanced control technology and professional and comprehensive solutions to make breakthroughs in more innovative applications in the energy industry, and accelerate the achievement of the dual-carbon goal!
