| Popis: | This paper proposes an improved version of the Fixed-point iterative method to solve the fault problems in three-phase power systems by phase-coordinates. The proposed method has non-expansive characteristic using for fault analysis and calculation, when the injected currents of the loads are with non-increasing functions about voltages. Based on the decoupling method, the network topologies enable to obtain the connections models for the system’s equipment and faults by adjusting the values of connected admittances, which makes the fault power systems easy to integrate into the proposed method rather than the multi-port Thevenin’s theory or the compensation method. And the matched version of the Fixed-point iterative method is designed and developed that can be used directly to calculate and analyze all kinds of simple faults and complicated faults both in the power systems and in the power system of multiple parallel lines. The validity and effectiveness of the proposed method can be demonstrated by the numerical test systems. |
