输电系统中变压器的最佳运行分析

主要研究和探讨了变压器的功率损耗、两台变压器并联运行时的自然功率分配及最佳功率分配、两台变压器电阻的比值及功率分配与变压器电阻的关系、两台变压器负荷S与其内阻RB的关系,并且分析了变压器的最佳运行区、临界负荷和两台并联运行变压器的最佳运行,比较了各种型号的两台变压器组合后在运行一定时期的总费用,确定出费用的最低值。结果表明,当为SFL1-10000/35×2的组合时,总投资为220.8万元,变压器运行在最佳区。

Analysis of Optimal Operation of Transformer in Transmission System

This paper mainly studied and discussed on several aspects such as power loss of transformer,the natural power allocation and optimal power allocation when two transformers operating in parallel,the ratio of the two sets' resistance,the relationship between power allocation and transformer's resistance and the relationship between load S and their resistance RB of two sets.It was also analyzed that transformer's optimal operation area,critical load,and the optimal operation of two transformers in paralleled.Moreover,comparisons of total cost of apiece type two sets assembled were done,and then the lowest cost was obtained.When assembled with SFL1-10000/35×2,the total investment was 2 2080 000 yuan,the transformer operated in optimal area.
