Abstract

Abstract: Aiming at the problem of abnormal reactive power distribution of two parallel running 220kV transformers of Shangmiao substation manufactured by different factories, according to relevant theory, combining with practical running situations, the ring current of highvoltage side and middlevoltage side under parallel running condition was analyzed, and the treatment measures were proposed.

Key words: on-load voltage regulating transformer, parallel run, ring current, reactive power
