This paper proposes an initial firing angle control algorithm according to the energy consumption and regenerative energy of a 12-pulse parallel connected dual converter for urban railway power substations. In this converter, the control scheme is divided into three operating modes depending on the electric energy flow of the train. When a train departs a(More)
Parallel-connected 12-pulse thyristor dual converters are connected to the up/down trolley line in urban power substations. When there are high-traffic trains on the up trolley line or the down trolley line, the electric energy, i.e., energy consumed and regenerative energy, increases. During this time, two converters are connected in parallel to supply(More)
