Improving dynamic stability of a wind turbine using a magnetic continuously variable transmission

Abstract

Nowadays, wind power engineering is developing in two equal directions. The first one is the increase of rated power for a single wind turbine by mass and dimensions parameters of a wind turbine with the use of high-voltage generators. The second one is modernization of wind turbine elements and implementation of modern control systems for a whole wind turbine and for its elements to enhance power generation. These power sources are characterized by the low inertia and the small margin of dynamic stability under sharp power variations, for example, under short circuits. The present paper is devoted to the use of a magnetic continuously variable transmission for synchronization of generators in the power system under transient processes.
