OPTIMIZATION OF STEP-DOWN SUBSTATION TRANSFORMER OPERATION MODES OF OIL INDUSTRY NETWORKS
Keywords:
transformer substation, economical power distribution, transformation ratio of transformers, series reactance compensation, power losses, mode optimization.Abstract
The article deals with the step-down substation transformer operation modes to reduce their power and energy losses due to economical load power distribution in case when different capacity transformers are installed on the substation. It is shown that the economical load power distribution, which corresponds to the minimum power losses, differs from the natural one because of connection layout heterogeneity. The econo mical mode of simultaneous operation of the different capacity transformers can be achieved by changing their transformation ratio. Another possible way of transformer modes optimization is series reactance compensation of one of the transformers. The mode optimization by changing the transformation ratio is one of the simplest organizational arrangements to decrease power losses. Economic efficiency of this way of mode optimization depends on the connection layout heterogeneity degree
