Abstract |
This paper proposes a power flow current injection model of the Scott transformer in an autotransformer (AT) railway feeding system, using with the current-based Newton-Raphson power flow method. The model is formulated by circuit analysis and represented as a double current source for each secondary supply phase. A test system with different load conditions is established to simulate and test the effectiveness of the proposed model. The powers on primary and secondary side of the transformer, voltage unbalance, and node voltages in the catenary system can be obtained from the test simulation and prove the effectiveness and feasibility of the proposed model.
