A Review of Key Technologies for Converting Thermal Power Units to Condensers in New Power Systems

Around the requirements of green and low-carbon development of energy, in the context of building a new power system with new energy as the mainstay, the transformation of thermal power units into condensers can not only play the role of thermal power units to hold up the supply, but also provide a new way for the transformation and development of thermal power generation. The problem involves theories and methods in the fields of power system stability, thermal power unit transient analysis, excitation control, generator transformation and remaining life assessment, which is a common bottleneck and difficult problem of multidisciplinary cross-fertilization. This paper summarizes and analyzes the impact of thermal power units retrofitting to condensers on power systems, key technology research and economic evaluation, and proposes relevant research ideas and specific routes.
