Parameter Sensitivity Analysis of a High-Voltage,Vaporization-Cooled,Three-Phase,Core-Type Transformer.

摘要

This parameter sensitivity analysis considers which independent design parameters have the most influence upon the determination of the weight and volume of a high-voltage,vaporization-cooled,three-phase,core-type transformer. The analysis is conducted through the use of a computer program which given a set of independent design parameters calculates a consistent set of values for the transformer's dependent design parameters. Two of the dependent design parameters are weight and volume. Initially,the weight and volume are determined for a reasonable set of independent design parameters. Then each independent design parameter is varied while all other independent parameters are held constant. With the weight and volume of th initial design as the common reference points,the comparison of the graphs of weight and volume as functions of the individually varied independent design parameters is the basis of the analysis. The analysis shows that the independent design parameters which most influence the determination of the weight and volume of the transformer are the power-out of the transformer,voltage-in,voltage-out,frequency of operation,number of inside secondary layers,maximum flux densities,conductor cooling rates,and the parameters which specify the core leg cross sectional areas.
