Abstract

The paper proposes a method to calculate voltage across faulted open port of short circuit fault and open conductor fault in detail. Based on the superposition theory, the formula is deduced to calculate voltage across faulted open port of short circuit fault when the potential values and the phrase angles of generators in power system unequal to each other. On the basis of superposition theory and the network theory, the practical formula to calculate voltage across open port of open conductor fault is obtained. Finally, the empirical study shows that the method can improve the calculation accuracy of voltage across faulted open port.
