Abstract

Demand type of power is divided into residential, industrial and commercial three types. Feeders loading are combination with the three type demands to form residential-oriented, industrial-oriented and commercial-oriented. Different demand-oriented loading of feeders affect the load flow with different line model such as lumped model, π model and distributive model. In this paper, chosen a main transformer at Wei-Wu substation which loadings is summation by the connective feeder’s loadings. By using the PSS/E software to find the maximum power and power margin under different power delivery. With the testing result, the power margins is relative with the various categories of main transformer assumes tendency of the inverse ratio.
