Overview and application of large thermal power excitation localization
摘要
Abstract
It is necessary to break the technical barrier and make breakthroughs in information system,control system,device and other aspects when reforming large thermal power excitation system domestically.The article first systematically concludes and summarizes the key technologies of modern excitation technology,including control and command subsystems,communication subsystems,rectifier subsystems,and excitation subsystems.It analyzes and summarizes the research status,existing problems,and difficulties involved in each technology at home and abroad.Secondly,the localization and replacement process of the HN-i6200 excitation system for large-scale supercritical 670 MW thermal power units was described.Targeted design was carried out to meet the special requirements of the excitation system operation for thermal power units,and highly reliable domestic DC breakers were developed.Through experimental research,the operation strategy of the excitation system for thermal power units was overcome,and a nationally produced HN-i6200 excitation system was successfully developed.The on-site testing and system modeling have verified the working performance of the nationwide production excitation system,providing technical and practical references for the localization of excitation technology in the power industry.关键词
