The two 1000MW ultra-supercritical coal-fired generating units of Guonong (Lianjiang) Port Power Co., Ltd. are the first demonstration project of energy conservation and emission reduction upgrading and transformation of coal power units of 1 million kW approved by the National Energy Administration and the key construction project of Fujian Province. The project integrates more than 20 advanced technologies at home and abroad, and the unit's performance is leading, the operation advantage is outstanding, and the environmental efficiency is leading. It has a wide range of technical guidance and demonstration significance in the industry.
In addition, the project adopts the world's first 2-in-1 frequency conversion center technology, which can further reduce the auxiliary engine energy consumption and plant power consumption rate, and applies the 100% high voltage bypass with the safety valve function, which can realize the three working conditions of stopping the furnace, the generator with plant power, and the turbine idling. The unit operates flexibly and has a deeper peak load capacity. It plays an exemplary role in the depth peak regulation in Fujian Province.
During the trial operation of the unit, the system equipment ran smoothly, all parameters met the requirements of the design technical specifications, the load rate of the unit reached 100%, the input rate and accuracy rate of thermal control protection, electrical protection and automatic devices reached 100%, and the environmental protection equipment such as desulfurization, denitrification and dust removal was put into operation at the same time with the host, and the environmental protection emission indicators and the quality of soda water met the national standards. To achieve safe, efficient, green and low-carbon operation of the unit.
"During the construction of the project, we tightly controlled the six dimensions of safety, efficiency, environmental protection, low carbon, flexibility and wisdom." Xin Xing, deputy director of the engineering department of Guoneng (Lianjiang) Hong Kong Power Co., LTD., said that the project is a typical representative of domestic clean green, efficient and low-carbon, flexible and safe, intelligent and smart coal power units.
