Short-circuit analysis of the onsite electric power system at Ringhals unit 4 MIKAEL NILSSON Department of Energy and Environment CHALMERS UNIVERSITY OF TECHNOLOGY ABSTRACT Because of an upcoming modernization of the electric system in unit 3 and 4 at Ringhals AB, new short-circuit current calculations have to be made. IEC 60865-1:2011 is applicable to the mechanical and thermal effects of short-circuit currents. It contains procedures for the calculation of: the electromagnetic effect on rigid conductors and flexible conductors, the thermal effect on bare conductors. For cables and insulated conductors, reference is made, for example, to IEC 60949 and IEC 60986. IEC 60865-1:2011 is applicable to the mechanical and thermal effects of short-circuit currents. It contains procedures for the calculation of: the electromagnetic effect on rigid conductors and flexible conductors, the thermal effect on bare conductors. For cables and insulated conductors, reference is made, for example, to IEC 60949 and IEC 60986. In the new version of IEC Standard Short-Circuit Calculation, the short-circuit current at the fault location is calculated in a first step, which is caused by the voltage sources, and the VSC...
