Abstract: Under-damped and low inertia problems caused by a large number of power electronic converters connected to power systems can be solved by virtual synchronous machine technologies. This paper illustrated the origin and development situation of virtual synchronous machine technologies, analyzed the topological structure and working principle of virtual synchronous generators and motors, and expounded the specific application of virtual synchronous machines in territories, such as new energy resources grid connected, voltage source converter based high voltage and electromobile, pointing out that this technology has the extensive application prospect in the fields such as optimal electric power system operation, plug and play of new energy grid connected equipment implement etc.
Key words: virtual synchronous machine; synchronous machine; power system; virtual inertia
