VECTOR ASYNCHRONOUS ELECTRIC DRIVE INVARIANT WITH RESPECT TO THE MOMENT OF CHARGE WITH ACTIVE ENERGY TRANSFORMER FOR MACHINE OF THE SLUGS CONTINUOUS CASTING
Abstract
In the articles there are presented two systems of vector asynchronous electric drives, invariant to vibrating load moment:
1) the traditional x-network of rectification in direct current element is used, and also the positive back coupling on oscillating term of load moment is embedded for guarantee of invariance;
2) in the direct current element there is applied active rectifier, and for guarantee of invariance there is used the positive back coupling on full load moment.
The presented in the article arguments prove advantage of the second system over the first one.
