Abstract

Forced cooling have been utilized for many years to increase transformer loading capacity. Method of transformer cooling system control affects its thermal performance directly. So, it is possible to prevent from undesired operational conditions such as accelerated ageing and critical hot spot temperature to some extent by proper control of cooling system. In this paper, the method of transformer cooling control in online monitoring system is addressed. Also, advantages of this control scheme over traditional method are discussed and demonstrated by simulation results.
