The paper considers the principle of stabilization for the rotation speed with the use of a magnetic CVT in the form of a magnetic gearbox providing the required reduction coefficient. The paper is devoted to investigations of transients in a autonomous power system consisting of wind turbines with synchronous generators with permanent magnets under sudden change wind speed. The investigation involves...
The paper presents a structure of a magnetic gearbox. It is shown that a simulation model of a magnetic gearbox can be reduced to the two-mass system. Based on the representation of force impact of a magnetic field between two halfcouplings by inertialess flexible coupling, the structural model of the magnetic gearbox is developed.
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...
The relevance of the research is caused by the fact that more than two thirds of territories in Russia do not have centralized power supply. There are small isolated power systems consisting of several loads ranging from 1 to 15 MW. Unfortunately, the share of small power plants in the world does not exceed 25%. Another part is large gas turbine generators with powers over 20 MW. One of the reasons...
