Abstract

En 中文

Classical fault analysis methods for power systems are based on symmetrical components to represent various fault configurations. The complete electrical network is decomposed using a complex transformation matrix into decoupled zero, positive and negative sequence circuits. Faulted power system steady-state voltages and currents are computed using a nodal analysis solution method. This paper presents an extension of the above methodology using discretized RLC elements for the computation of the actual transient response of a network for various fault types. The decoupled networks are obtained using a real transformation matrix.
