Summary of research on synchronous generator excitation system

Under the background of “double carbon” strategy including large-scale grid-connection of renewable energy and the power grid interconnection, new situations have put forward increasingly stringent requirements for the safety and stability of power systems in recent years. In this case, the excitation system plays an increasingly important role in the power system. The article summarizes the basic principle of the excitation system, discusses the current status and development tendency of excitation system from excitation mode and core parts of excitation system such as de-excitation device, rectifier device, excitation regulator. The article also discusses the basic theory and development direction of the excitation control strategy from the aspects of AVR and PSS.
