Abstract

A method is described for selecting generator step-up and auxiliary transformer tap positions to provide the desired reactive power requirements in a coal burning power plant. It is shown how a generator could be made to absorb reactive power, when previously unable to do so, by the adjustment of tap positions on the generator step-up and auxiliary transformers. The approach described provides an indication of the range of reactive power outputs that are available for different tap positions. This information would facilitate the alteration of transformer tap positions to make more effective use of generator reactive power resources
