Optymalizacja konstrukcji uzwojeń stojanów turbogeneratorów chłodzonych bezpośrednio wodą

In the paper, three most often applied structural solutions of winding with direct water cooling are presented. The optimization procedure of these structural solutions is discussed. The objective functions which can be used in the procedure of optimization of these structural solutions are described. The drawings of three structural solutions and average rises of temperatures in the elementary wires of winding conductors for optimized structural solutions are presented. The results of optimization calculations which effected with optimal constructions of three water cooled winding types are listed in table 1. For the water-cooled winding construction type 1, the area of acceptable solutions with technical constrains taken into account is presented on a 3D graph. The attempt was taken to show the need for the use of optimization procedures in designing of direct water cooled windings.
